An ingredient commonly found in toothpaste could be employed as an anti-malarial drug against strains of malaria parasite that have grown resistant to one of the currently used drugs. This discovery was aided by Eve, an artificially intelligent 'robot scientist.'
Researchers have described a new technique to improve chemical stability of electrode materials which can extend the lifespan by employing a very little amount of metals. Using computational chemistry and experimental data, the team observed that local compressive states around the Sr atoms in a perovskite electrode lattice weakened the Sr-O bond strength, which in turn promote strontium segregation.
In an advance that could push cheap, ubiquitous solar power closer to reality, researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors.
A new article outlines a pioneering method of screening a person's diverse set of antibodies for rapid therapeutic discovery. Antibody proteins are an important part of the human immune system that specifically target foreign viruses and bacteria, and they have been the fastest-growing class of approved drugs in the past several decades.
A public database of more than 300 substances used to dye hair will help accelerate research and development work on more sustainable hair color. Researchers say computer modeling can save years of lab work and millions of dollars.
Photons with energy higher than the 'band gap' of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy is lost very fast, as it is converted into heat so it does not contribute to the voltage. Researchers have now found a material in which these hot electrons retain their high energy levels for much longer.
Nitrogen-based synthetic fertilizer forms the backbone of the world food supply, but its manufacture requires a tremendous amount of energy. Now, computer modeling points to a method that could drastically cut the energy needed by using sunlight in the manufacturing process.
A nanostructured composite material has shown impressive performance as a catalyst for the electrochemical splitting of water to produce hydrogen. An efficient, low-cost catalyst is essential for realizing the promise of hydrogen as a clean, environmentally friendly fuel.
Metal-organic perovskite layers for solar cells are frequently fabricated using the spin coating technique on industry-relevant compact substrates. These perovskite layers generally exhibit numerous holes, yet attain astonishingly high levels of efficiency. The reason that these holes do not lead to significant short circuits between the front and back contact has now been discovered.
Conjugated tetraenes are important key substructures in electronic materials, natural products and pharmaceutical molecules. However, they are difficult to synthesize. Now, researchers in Japan have achieved a new synthetic route of conjugated tetraenes from inexpensive and easily available 1,3-butadiene and substituted acetylenes by a one-pot approach under mild conditions.
Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, researchers have developed a new class of robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom.
