Published Producing hydrogen and fertilizer at the same time
(via sciencedaily.com) Original source This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
Published Crystals from radioactive metal actinium
(via sciencedaily.com) Original source Researchers grew crystals containing actinium and illuminated them with X-rays to learn how the radioactive metal binds with other elements. That information could help design better cancer treatments.
Published When to trust an AI model
(via sciencedaily.com) Original source A new technique enables huge machine-learning models to efficiently generate more accurate quantifications of their uncertainty about certain predictions. This could help practitioners determine whether to trust the model when it is deployed in real-world settings.
Published Microbeads with adaptable fluorescent colors from visible light to near-infrared
(via sciencedaily.com) Original source Researchers have successfully developed an environmentally friendly, microspherical fluorescent material primarily made from citric acid. These microbeads emit various colors of light depending on the illuminating light and the size of the beads, which suggests a wide range of applications. Furthermore, the use of plant-derived materials allows for low-cost and energy-efficient synthesis.
Published A chemical claw machine bends and stretches when exposed to vapors
(via sciencedaily.com) Original source Scientists have developed a tiny 'claw machine' that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors. The findings point to a technique that can enable soft actuators--the parts of a machine that make it move--to perform multiple tasks without the need for additional costly materials. While existing soft actuators can be 'one-trick ponies' restricted to one type of movement, this novel composite film contorts itself in different ways depending on the vapor that it is exposed to.
Published A better way to make RNA drugs
(via sciencedaily.com) Original source RNA drugs are the next frontier of medicine, but manufacturing them requires an expensive and labor-intensive process that limits production and produces metric tons of toxic chemical waste. Researchers report a new, enzyme-based RNA synthesis method that can produce strands of RNA with both natural and modified nucleotides without the environmental hazards.
Published Scientists create computer program that 'paints' the structure of molecules in the style of Piet Mondrian
(via sciencedaily.com) Original source Scientists have created a computer program that 'paints' the structure of molecules in the style of famous Dutch artist, Piet Mondrian. Researchers are opening eyes and minds to the beauty of molecular structure, as well as posing new questions about the form and function of the molecules themselves.
Published Nanoplastics and 'forever chemicals' disrupt molecular structures, functionality
(via sciencedaily.com) Original source Researchers have made significant inroads in understanding how nanoplastics and per- and polyfluoroalkyl substances (PFAS) -- commonly known as forever chemicals -- disrupt biomolecular structure and function. The work shows that the compounds can alter proteins found in human breast milk and infant formulas -- potentially causing developmental issues downstream.
Published Study finds health risks in switching ships from diesel to ammonia fuel
(via sciencedaily.com) Original source Without additional regulation, burning ammonia in ship engines could cause serious impacts on air quality that could result in more than 600,000 additional premature deaths per year, according to new research.
Published New solutions to keep drinking water safe as pesticide use skyrockets worldwide
(via sciencedaily.com) Original source Water scientists have proposed a more effective method of removing organic pesticides from drinking water, reducing the risk of contamination and potential health problems.
Published BESSY II shows how solid-state batteries degrade
(via sciencedaily.com) Original source Solid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes.
Published Researchers show promising material for solar energy gets its curious boost from entropy
(via sciencedaily.com) Original source Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
Published Moving from the visible to the infrared: Developing high quality nanocrystals
(via sciencedaily.com) Original source Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
Published Mining rare earth metals from electronic waste
(via sciencedaily.com) Original source A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice.
Published Diagnosing different forms of dementia now possible using artificial intelligence
(via sciencedaily.com) Original source Ten million new cases of dementia are diagnosed each year but the presence of different dementia forms and overlapping symptoms can complicate diagnosis and delivery of effective treatments. Now researchers have developed an AI tool that can diagnose ten different types of dementia such as vascular dementia, Lewy body dementia, and frontotemporal dementia, even if they co-occur.
Published Chemistry inspired by one-pot cooking
(via sciencedaily.com) Original source Is it possible to create a new class of materials from very different substances using the 'one-pot synthesis' approach? Chemists explain how they enable the synthesis of such novel materials.
