Author: Claire Hendershot, Broad Institute of MIT and Harvard Developing a new drug can take years of research and cost millions of dollars. Still, more than 90% of drug candidates fail in clinical trials, with even more that never make it to the clinical stage. Many drugs fail because they simply aren’t safe. Researchers at […]
Adopting a more sustainable energy portfolio is imperative to address and alleviate the impacts of climate change. A key process is energy harvesting versus energy “production”. In this vein, a potentially viable approach involves the conversion of dissipated heat into electrical energy via the use of thermoelectricity. This method has the potential to contribute significantly […]
You can think of our atmosphere as a big chemistry set, a global churn of gaseous molecules and particles that constantly bounce off and change each other in complicated ways. While the particles are very small, often less than 1% of the thickness of human hair, they have outsized impacts. For example, particles are the […]
The bottom-up design of hierarchically organized nanostructures is a powerful strategy to achieve new materials with innovative functionalities. To a large extent, this approach takes inspiration from the ability of living organisms to engineer hybrid nanocomposites both for structural and functional purposes. Intense research has been dedicated to synthesizing biologically inspired textures and shapes mimicking […]
The development of luminescent organic radicals has resulted in materials with excellent optical properties for near-infrared (NIR) emission, like organic light-emitting diodes (OLEDs). Light generation in this range could be used for healthcare diagnosis and treatment to surveillance, communications and other security applications. Although an external quantum efficiency greater than 20% in electroluminescence has been […]
Author: Ambuj Tewari, Professor of Statistics, University of Michigan Over 100 years ago, Alexander Graham Bell asked the readers of National Geographic to do something bold and fresh – “to found a new science.” He pointed out that sciences based on the measurements of sound and light already existed. But there was no science of […]
Carbon monoxide (CO) oxidation (2CO + O2 → CO2) on platinum (Pt) group metal surfaces is the model heterogeneous gas/surface catalytic reaction. Pt itself is of the upmost importance as a catalyst for car exhaust cleaning or for the water gas shift reaction, whereas Pt crystal surfaces are model systems for investigating the catalytic CO […]
“Helicene” is the name introduced by Newman in 1955, to describe the benzologues of phenanthrene in which the extra ortho -condensed rings give rise to a (regular) cylindrical helix. The pioneer work of Newman in this field cannot be overemphasized; his brillant synthesis and resolution of [6]helicene will remain as a landmark, for it opened […]
Convenient fast charging and energy density of lithium-ion batteries have long been considered a trade-off, which has hindered the widespread adoption of electric vehicles. A new process will help develop stable, high-energy-density lithium-ion batteries capable of fast charging. A crucial prerequisite for the widespread adoption of electric vehicles (EVs) is the enhancement of lithium-ion battery […]
In organic chemistry, π-stacking systems are supramolecular structures that arise due to the dispersion force, a type of intermolecular noncovalent interaction. They are a common occurrence in nature. The stabilized structure of DNA is a very prominent example of a π-stacking system, and so are the arrangement of amino acids in certain proteins. Interestingly, π-stacking […]
