Surface tensions were determined using the pendant drop method, in which a drop is suspended from a needle into air. Images of the droplet were taken and analyzed in MATLAB to determine the interfacial tension between the drop and air. Interfacial tension measurements between silicone oil and mineral oil were determined by measuring the contact angles formed by placing a drop of light mineral oil (NF/FCC-grade; Fisher Scientific) in a bath of 100 cSt oil (Sigma-Aldrich) and solving Young’s equation. The contact angles were measured using FIJI ImageJ software.
There is a lot of research into batteries so expect the lithium batteries to be replaced by something better/cheaper in the future.
In mid-century America, cities such as Los Angeles and New York were repeatedly shrouded in thick brown fog—sometimes so lung-burningly toxic that it was mistaken for a chemical-weapon attack by a foreign power—and air pollution became an urgent issue. Legislation to curb it began appearing in the U.S. and other countries in the nineteen-fifties. After the passage of the Clean Air Act, government research dollars flowed to scientists looking to understand and to mitigate the sources and the health effects of air pollution. But there was still almost no funding available for research into indoor air. Charles Weschler became one of just a few scientists in the field when he went to work for Bell Labs, in 1975, soon after completing a Ph.D. in chemistry. The company had noticed that the equipment in its telephone switching offices was failing faster than expected; it turned out that wire relays were being eaten away by an acidic, invisible indoor smog. Weschler told me that the little indoor-air research that was being done at the time was mostly geared not toward protecting people but toward preserving things.
Large scale aerobic production of PHB can be carried out using genetically engineered E. coli strains in bioreactors [11]. The advantages of using recombinant E. coli for the production of PHB include rapid growth, accumulation of PHB greater than 50 % of cell weight [12], and the ability to utilize inexpensive carbon substrates [13, 14].
Think about a small economy car with a 50 mile battery range, and a small propane engine that offsets the energy drain to extend the mileage. Could this be a cheap way to significantly improve the range of the vehicle and keep an economy level cost? Similar to a hybrid but less effective and much cheaper?
For its part, the BLM maintains that air quality is best considered later in the process, when companies formally request the chance to drill and the Bureau can better account for how much activity there will be. In addition, Colorado has upgraded to a state-of-the-art air modeling program that continually runs simulations of air quality across the state to incorporate projected new development, which it says will enable quicker and better decisions.
But, but . . . just like the world’s major fiat currencies are tethered to their underlying economies, Bitcoin is tethered to hype. Shouldn’t hype be at least as good as an economy that produces things? Especially if it’s “digital / tech hype?”
The FDA delivered another wake-up call to manufacturers of laser-based biomedical systems. In April 2018, following Medtronic’s (Minneapolis, MN) Class 2 recall of its Visualase Cooled Laser Applicator System (VCLAS) for MRI-guided laser brain surgery, the FDA issued a Class I recall(the most serious type) for Monteris Medical’s (also in Minneapolis) NeuroBlate MRI-guided ablation system because of unexpected heating of laser delivery probes. Soon afterward, the FDA issued a general warning about the risk of tissue overheating during use of such systems, owing to inaccurate magnetic resonance thermometry. To address the problem, the manufacturers provided guidance to users, and Monteris obtained 510(k) clearance for a fiber-optic-controlled, cooling-equipped laser probe.
