    Transfer of super-cooled or cryogenic fuel from one tank to another in the zero gravity of space may one day be a reality. But the challenges of measuring fuels and fuel levels in the weightlessness of space must be solved first.

    One of the things highlighted in the news this week is the risks of contamination from removing—”doffing”—personal protective equipment. “Meticulous removal, or doffing, of PPE is as important as its meticulous donning,” wrote infectious disease physician Amesh A. Adalja in “Ebola Lessons We Need To Learn From Dallas.” Most chemists don’t need to fear Ebola, but they do wear PPE to protect from chemical exposure. I asked Iowa State University lab safety specialist Ryan Wyllie and biosafety specialist Amy Helgerson what chemistry researchers should keep in mind when…

  • NASA creating a virtual telescope with two small spacecraft

    24 Oct 2014 | 4:25 pm
    Although scientists have flown two spacecraft in formation, no one ever has aligned the spacecraft with a specific astronomical target and then held that configuration to make a scientific observation -- creating, in effect, a single or "virtual" telescope with two distinctly different satellites.

  • First protein microfiber engineered: New material advances tissue engineering and drug delivery

    23 Oct 2014 | 8:10 am
    Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale -- a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.
  • RF heating of magnetic nanoparticles improves thawing of cryopreserved biomaterials

    23 Oct 2014 | 7:07 am
    Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Reserachers leverage a clinically proven technology platform, in magnetically heated nanoparticles, to overcome this major hurdle limiting further…

    A comment on personal versus institutional responsibility by Suzanne Donovan, an infectious disease specialist at Olive View-UCLA Medical Center, who spoke on NPR on Sunday about the Texas health care worker now infected with Ebola: And I think it’s really important that there is no finger-pointing at the healthcare worker so that the healthcare worker did something wrong because this is all about training and having the appropriate equipment. … I think in a country like the United States, where there’s very few cases, the environment is very safe and the equipment is…
  • Preparing piranha

    Piranha solutions are used to remove organic residues from substrates. Typically a 3:1 mixture of concentrated sulfuric acid to 30% hydrogen peroxide, it is highly corrosive and a powerful oxidizer. Simply mixing the solution is dangerous. And mixing piranha begs the question raises the question: Add the acid to the peroxide, or the other way around? Everyone hopefully learned in chemistry labs to “never cover an acid”–that is, when diluting, always add acid to water, not the other way around. For piranha, however, best practice is to add the peroxide to the acid. Robin…

At a press briefing yesterday, Chemical Safety & Hazard Investigation Board investigators spoke about what they’ve learned so far regarding an incident at a Denver high school that sent four students to the hospital on Monday: The teacher lit a small pool of methanol to demonstrate its flame properties.

    In last week’s exploding pianos post, the experiments focused on the addition of flour to a theatrical “flash pot.” How important the flour was to the ensuing explosion was never resolved. Flour is, in fact, a combustible material–along with sugar, grains, tobacco, plastics, wood, paper, pesticides, pharmaceuticals, dyes, coal, and metals. The U.S. Chemical Safety & Hazard Investigation Board has been warning about combustible dust hazards in industry for years. A CSB report on combustible dust issued in 2006 recommended that the Occupational Safety & Health…

    Two nurses who treated the late Ebola-virus victim Thomas Eric Duncan have been diagnosed with Ebola virus as well.  They treated him at the Texas Health Presbyterian Center hospital in Dallas, where he died on October 8 after traveling there from Liberia, where he acquired the virus.  Despite apparently following the protocols recommended by the U.

    Okay, suppose some of the most extreme voices warning of global warming are right.  Suppose we really do face the inundation of much of the world's coastlines in a generation or two.  Even if, starting tomorrow, nobody ever burned a drop or a gram of fossil fuel ever again, the carbon dioxide now in the atmosphere might take hundreds of years to fall to pre-industrial levels.  So simply implementing restrictions on fossil fuels to reduce carbon-dioxide levels may not do the job fast enough.  What do we do in the meantime?  To use an automotive analogy, if you're going…

    The safety of nuclear weapons is the theme of Eric Schlosser's 2013 book Command and Control:  Nuclear Weapons, the Damascus Accident, and the Illusion of Safety.  After reading the book, my own reaction is mirrored in a quote Schlosser cites from General George Butler, who became head of the U. S. Strategic Air Command shortly before the Soviet Union came to an end in 1991.  After familiarizing himself with the secret plans for nuclear war, Butler later remarked that "we escaped the Cold War without a nuclear holocaust by some combination of skill, luck, and divine…
  • The Limits of Diversity

    This month's Scientific American devotes twenty pages to articles on diversity in science—the shameful lack thereof, and what can be done about it. One piece is a kind of confessional by a Lockheed Martin engineer who quickly moved into management and found that as she chose staff from widely varying backgrounds, the quality of her group's work increased.  Other articles cite social-science studies that show diverse organizations are not only more socially just; they do better science and engineering too.  The reader of these paeans to diversity could not be blamed for taking away…

  • Alaskan megathrust fault more active under Kodiak

    22 Oct 2014 | 10:27 pm
    The 1964 Alaska Earthquake was 9.2 in magnitude and caused dramatic destruction and dramatic examples of surface rupture, subsidence, and liquefaction. New paleoseismic evidence points to a previously unknown earthquake that happened on the same fault segment approximately 500 years ago. This new evidence would change the recurrence interval for the earthquakes on the Alaskan megathrust fault, which would affect seismic hazard in Alaska, but could also increase the tsunami hazard in places as far away as California and Hawaii.

    It's October 2 again, and today would have been Karl Terzaghi's 131st birthday. As I was reflecting on Terzaghi and some of his quotes, I was reading a passage from Professor's Goodman's biography1 that described a talk that he gave in 1924 entitled "The Way to Happiness." I thought this would be a nice change of pace from some of his more famous quotes and topics. Here are some selections from Goodman's description of the presentation. ...This stems from application of the law of selection, which "leads to the survival of the most clever, most reckless, and most hypocritical.

    A recent report from the New York Fed looks at the economic benefits of college. While there has been a great deal of talk about the “bubble” in higher education the Fed finds college is very wise economically for most people. They do find a larger portion of people that are not getting a great return on their investment in higher education. That could well indicate students studying certain majors and perhaps some people with less stellar academic skills would be better off economically skipping college.

    Self-driving cars was something that seemed very far-fetched when I first read Google was seriously investing in pursuing that idea as a commercially viable product (Google’s Self Driving Car – 2010 post). I quickly became convinced they were right. I still think it is questionable if they will succeed (the political issues may well be even more difficult than technical ones). But the chances of success seem reasonable and the investment in research could provide a huge payoff. Google’s self driving cars have driven 700,000 miles without an accident already; which is amazing.

The driver had ignored several less obvious signals that they were headed for danger. This is an application of one of my favorite management (and industrial engineering) concepts: mistake proofing. As I have stated before, often it is really mistake making more difficult rather than mistake proofing. This truck driver ignored the first several…

However, nanotechnology has pushed through many barriers that previously seemed insurmountable.

In 1995, we were assured that it was impossible to go smaller than 250 nanometres. Despite this, today's... Is there a limit to Moore's law?

  • The Engineering Workforce Problem: Doing More with No More

    22 Oct 2014 | 12:00 am
    According to a 2010 Pew research study, roughly 10,000 Baby Boomers will turn 65 every day for the next 18 years. This increase in retirees means the skilled engineering workforce that companies have depended on will leave behind more openings than there are people to fill them. In December 2012, Aberdeen conducted research into the state of the engineering and technical workforce and found out a majority of the 526 companies polled (over 60%) feel understaffed in their engineering positions.This Analyst Insight will look into how Best-in-Class manufacturers successfully win the fight against…

  • Top 10 Important Things to Know for SIPs

    Dean Dalvit
    4 Oct 2014 | 12:41 am
    With the growing popularity of SIP designed homes, it is important to know some critical details that are different than traditional stick frame design. Below is a list of what I have developed as important details to consider as early as the pre-design stage as well as tips during construction as well: 1.) The thickness of the SIP wall is a critical factor in determining your layout geometry. Most SIP manufacturers provide panels in both 2×4 and 2×6 varieties, however, bear in mind that those sizes predicate that the 2×4 or 2×6 is sandwiched between the panels. Therefore,…

    Being licensed as both professional engineers and professional land surveyors allows us to offer significant cost savings and drastically helps improve the efficiency of our projects. For example, when we do a site visit at the start of a project we are already thinking about what surveying services are going to be required in order to complete the civil engineering that is needed for that particular project. To that end, we make sure our clients are not paying for what we call “overkill” surveying. In this competitive marketplace there is no need for clients to pay for a surveyor…

  • The 3 Most Important Things to Remember Before Starting an Engineering Project

    Chris Walker
    22 Oct 2014 | 8:40 am
    I have spent the day building a wooden playhouse for my daughter. It’s been a bit of a mission and has taken much longer than it should have. I’ve been reminded of a few basic principles which will be helpful in all sorts of engineering situations, not just when building a glorified garden shed. Measure Twice. Cut Once. Perhaps this is a more specific version of the more general principle of planning well. It’s always better to take time over making sure measurements are correct before committing to an irreversible course of action. Thankfully in my case, I only had one…

  • 3 Reasons Why People Think Engineers are Jerks. And Why They are Wrong

    Put Title “People don’t like engineers because engineers are always the ones who bring up all the problems.” When my manager told me this I had to take a moment to calm myself down and not be offended. After all, this manager was a fellow engineer, and a good friend, so I knew it wasn’t meant as an insult. But still the comment hurt: How could people not like engineers? It is true though; engineers tend to point out problems before they become apparent to others, and have a few tendencies which can bother our non-engineer colleagues and acquaintances. But many of these…

    The Mapping Network created a hydrographic and sediment survey for a property owners association in Cleveland, Ohio.   The main lake inlet has shallow water because sediment settles out at the mouth of the stream, creating deltas. These deltas impede fish migration, act as bedding areas for nuisance aquatic species, hinder recreational activities such as swimming and boating, and force property owners to extend their docks. The POA installed two sediment basins to capture sediment coming from the north but as you can see from the watershed map, much more sediment is arriving from the east…

    Lean Six Sigma is a management strategy that leaped into the forefront of business thinking when legendary executive Jack Welch applied it at General Electric in 1995 — and now more companies are adopting its principles to increase efficiency and reduce costs. At its core, Lean Six Sigma exists to improve the performance of business processes by identifying and removing the causes of waste and minimizing variation. I can’t think of a single business that wouldn’t benefit from those things. Start Early for Maximum Impact The key to getting the most out of Lean Six Sigma is adopting its…
  • Webinar: Master Planning Today for Payback Tomorrow

    Jon Schwartz
    19 Sep 2014 | 9:31 am
    Utility master plans are one of the most critical tools for campus infrastructure systems. Without a master plan in place, campus systems are flying blind, reacting to increased demands on the utility systems as they come. Each rushed decision impacts the next and creates cascading effects. The good news: With a little upfront planning today, utility master plans can help campuses achieve big paybacks tomorrow — and can update systems to run more efficiently and cleanly. What Is a Master Plan and Why Do I Need One? Simply put, a utility master plan (UMP) is a comprehensive study of existing…

    Two weeks ago, I was in Chicago for the 136th Annual National Guard Association of the United States (NGAUS) Conference. It’s the must-attend event for anyone who works in the defense industry, particularly with national security and disaster response.

  • LEED Leads to Big Energy Savings for Military Buildings

    8 Sep 2014 | 4:00 am
    The topic of energy savings for the military isn’t new, but in light of recent budget cuts for the U.S. Army, there’s a renewed focus on lowering operations costs for new and existing National Guard facilities. Top it off with a government mandate to design all new National Guard buildings to meet Leadership in Energy and Environmental Design (LEED®) standards, and that can lead to big energy savings for military buildings. When a building achieves LEED certification, it demonstrates that it meets environmental goals for sustainability, which inherently lowers operations costs in the…

    Scientists at Southampton University have revealed in a new study that feather shafts are made of a multiple layers of keratin, a fibrous material similar in construction to carbon fibre. Since their appearance over 150 million years ago, feather shafts or rachises have evolved to become some of the lightest, strongest and most fatigue resistant natural structures. Until now relatively little work has been done on their morphology, especially from a mechanical perspective and never at the nanoscale. Scientists at the University were the first to use a material testing technique called…

Typically the answer is that creating apps isn't quite as simple as using apps. But creating an Android app to control your latest OSHW invention can be pretty darn simple thanks to MIT’s App Inventor. In my opinion, it is one of the best-kept secrets in the maker community.

    While my current gig is serving as the President of a product development professional services firm, I’ve spent many years in companies large and small developing products as a mechanical engineer and also in engineering management. In those pre-consulting roles, I often was the person responsible for finding, engaging and managing product development service providers (see my earlier post on choosing a product development partner.) In fact, my experiences as an engineering management executive inside a large product company were the basis for starting IPS, our own consulting firm. What…
  • The Four Truths About Real Innovation

    17 Sep 2014 | 10:40 am
    DON’T TRY TO INNOVATE BY YOURSELF AT HOME! Or anywhere else. When we think of genius inventors, we’re still inclined to envision the mad scientist in his lab, or the lone Einstein changing the world as we know it. But the myth of the solitary genius inventor (Einstein collaborated frequently) no longer serves the tech community. In its place is a new understanding of collaboration, in pairs and groups, as the next big competitive advantage. In fact, chances are that a solo innovation effort will not be as successful as a partnered one. A new book, “Powers of Two” by Joshua Wolf…
  • New gTLDs: The Wild, Wild Web

    25 Aug 2014 | 7:02 am
    October of last year marked the beginning of a new wave of generic Top-Level Domains (gTLDs) becoming available to domain registrars. This revolutionary change is very exciting for a computer geek like me. Some of you may ask, “Ok, so what exactly is a generic Top-Level Domain?”, Wikipedia states that: A generic top-level domain (gTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. It is visible to Internet users as the suffix at the end of a domain name. In…
  • Consumer Devices for Business Applications: IBM’s Corporate Customers Deploying Apple Devices in the Field?

    mitchm11741
    28 Jul 2014 | 2:20 am
    A big, surprising deal between Apple and IBM was announced in the WSJ in July – the two giants announced the intention of having IBM offer Apple devices and Big Blue custom apps to corporate clientele. While such a strategy may make sense for supporting knowledge and BYOD (bring-your-own-device) workers, it misses the boat for major commercial vertical markets (i.e. utilities, logistics, warehouse, MRO, health care, retail, etc). A recent article in Wired magazine asks why commercial users of mobile computing devices are not readily gravitating towards consumer grade cell phone devices.

    Great product ideas surface every day. Sketches are drawn, teams are formed, new companies are born, business plans are written and everybody gets to work. The product varies – it could be a physical product, software, a new service or a complete solution – but the goal is always the same. A successful product. Enthused entrepreneurs frequently delve right into the design and development process, often misunderstanding the importance of asking the critical question: Exactly what am I designing and producing?  Design teams may have well developed concepts, great sketches and lots of…

    25 Oct 2014 | 6:06 am
    Before the engineer can design a foundation intelligently, he must have a reasonably accurate conception of the physical properties and arrangement of the underlying materials. The field and laboratory investigations required to obtain this essential information are called soil exploration or site investigation. A site investigation simply is the process of the collection of information, the appraisal of data, assessment, and reporting without which the hazards in the ground beneath the site cannot be known.

  • Advantages and Disadvantages of Concrete

    15 Oct 2014 | 8:42 am
    Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials acts as binder. The most important binding materials are cement and lime. Inert materials used in concrete are termed as aggregates. Most common aggregates are sand, brick chips, stone chips, gravels, shells etc.   Advantages of Concrete Ingredients of concrete are easily available in most of the places. Unlike natural stones Concrete is free from defects and flaws. Concrete can be manufactured to desired strength with economy. The durability of concrete is very high.

    The Top 5 Constructional Mistakes and Concrete Problems which can bring disastrous results if ignored are not the huge ones but very common in every construction work, which gets out of the notice of the Engineer-In-Charge in most of the cases. As I feel most of the bad construction takes places not due to the unwillingness of the Engineers, but mostly due to the lack of awareness about those small things which they take lightly and thinks they are of no major importance and will not affect the ultimate construction. I do partially agree with them to the fact that it will not harm the…
