Colloidal Quantum Dots…

Topics: Energy, Materials Science, Nanotechnology, Quantum Mechanics, Solar Power ABSTRACTSolution-processed colloidal quantum dot (CQD) solar cells are lightweight, flexible, inexpensive, and can be spray-coated on various substrates. However, their power conversion efficiency is still insufficient for commercial applications. To further boost CQD solar cell efficiency, researchers need to better understand and control how charge carriersContinue reading “Colloidal Quantum Dots…”

What They Meant…

Topics: Civics, Civil Rights, Democratic Republic, Existentialism, Fascism, Human Rights 100 photos, Time: In August 1955, Emmett Till, a black teenager from Chicago, was visiting relatives in Mississippi when he stopped at Bryant’s Grocery and Meat Market. There he encountered Carolyn Bryant, a white woman. Whether Till really flirted with Bryant or whistled at herContinue reading “What They Meant…”

The Black Edison…

Topics: African Americans, Civics, Civil Rights, History, Human Rights “If you can control a man’s thinking you do not have to worry about his action. When you determine what a man shall think you do not have to concern yourself about what he will do. If you make a man feel that he is inferior,Continue reading “The Black Edison…”

Snapping Polymer Discs…

Topics: Chemistry, Polymer Science, Materials Science, Research A polymer-based gel made by researchers in the US and inspired by the Venus flytrap plant can snap, jump and “reset” itself autonomously. The new self-propelled material might have applications in micron-sized robots and other devices that operate without batteries or motors. “Many plants and animals, especially smallContinue reading “Snapping Polymer Discs…”

Einsteinium Chemistry…

Topics: Chemistry, Einstein, Materials Science, Research To date, researchers have created more than two dozen synthetic chemical elements that don’t exist naturally on Earth. Neptunium (atomic number Z = 93) and plutonium (Z = 94), the first two artificial elements after naturally occurring uranium, are produced in nuclear reactors by the thousands of kilograms. But the accessibility ofContinue reading “Einsteinium Chemistry…”

Touchdown…

Topics: Mars, NASA, Perseverance, Space Exploration, Spaceflight Editor’s Note: This release was updated on Feb. 22 to correct the metric unit for the speed at which the rover’s wheels made contact with the surface to kph. New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, andContinue reading “Touchdown…”

Splitting Babies, Washing Hands…

Topics: Civics, Civil Rights, Existentialism, Fascism, Human Rights, Politics To split the baby is a reference to a story in the Old Testament in Kings 3:5-14, regarding a decision of Solomon that shows his wisdom when given a difficult task. Solomon as king was often asked to judge between people with difficult problems, and hisContinue reading “Splitting Babies, Washing Hands…”

Kondo Mimic…

Topics: Magnetism, Materials Science, Nanotechnology A new type of quasiparticle – dubbed the “spinaron” by the scientists who discovered it – could be responsible for a magnetic phenomenon that is usually attributed to the Kondo effect. The research, which was carried out by Samir Lounis and colleagues at Germany’s Forschungszentrum Jülich, casts doubt on current theories of theContinue reading “Kondo Mimic…”

Well Deserved…

Topics: Biology, COVID-19, Research, Science Anthony Fauci – director of the National Institute of Allergy and Infectious Diseases, an expert on HIV and immunoregulation, and the de facto public face of a science-based recovery from COVID-19 – has been named the winner of the 2021 Philip Hauge Abelson Prize, awarded annually by the American Association for theContinue reading “Well Deserved…”
