Carbon Storage…
Keeping the carbon: Biochar can be added to cement to sequester carbon within concrete. (Courtesy: Sabbie Miller) Topics: Biomass, Civil Engineering, Environment, Global Warming, Green Tech Replacing conventional building materials with alternatives that sequester carbon dioxide could allow the world to lock away up to half the CO2 generated by humans each year – about 16Continue reading “Carbon Storage…”
89 Seconds…
Topics: Applied Physics, Chemistry, Entropy, Environment, Existentialism Humans tend to chronicle worst-case scenarios, such as Armageddon (Judao-Christian), Pralaya (Hindu), and Ragnarok (Norse). If you follow the scripts for each, there is a “hack”: a insisted upon “happy ending” where everything is reborn anew, and those bothersome “others” that you couldn’t legislate or exterminate are killedContinue reading “89 Seconds…”
Plasmons and Diamonds…
Topics: Chemistry, Materials Science, Plasmons, Quantum Mechanics, Semiconductor Technology Researchers report plasmons in boron-doped diamond; quantum applicationsDiamond, often celebrated for its unmatched hardness and transparency, has emerged as an exceptional material for high-power electronics and next-generation quantum optics. Diamond can be engineered to be as electrically conductive as a metal, by introducing impurities like theContinue reading “Plasmons and Diamonds…”

A finished device: Optical microscope image of the transistor (left) and an ultra-scaled vertical nanowire (right). (Courtesy: Y Shao) Topics: Electrical Engineering, Materials Science, Nanoengineering, Nanomaterials, Nanotechnology, Semiconductor Technology A new transistor made from semiconducting vertical nanowires of gallium antimonide (GaSb) and indium arsenide (InAs) could rival today’s best silicon-based devices. The new transistors areContinue reading “Defeat of the Boltzmann Tyranny…”
Water and Lithium…
Emissions of Carbon Dioxide in the Transportation Sector, Motor Vehicle Miles Traveled, and Emissions per Mile Traveled by Light-Duty Vehicles Measured as a Percentage of Their Value in 1975 – Transportation sector emissions have not risen nearly as much as vehicle miles traveled because gains in fuel economy have reduced emissions per mile of travel.Continue reading “Water and Lithium…”

Ice sample on the melter during continuous ice core chemical analyses at the Desert Research Institute (Credit: Sylvain Masclin) Topics: Chemistry, Civilization, Democracy, Environment, Existentialism It’s perhaps historically appropriate that the word “ironic” contains “iron.” Mining and smelting minerals like iron represented technological highs at the Roman Empire’s peak. But those activities also produced enoughContinue reading “Lead, Iron, and Empires…”
