Published Concept for efficiency-enhanced noble-metal catalysts
(via sciencedaily.com) Original source The production of more than 90 percent of all chemical products we use in our everyday lives relies on catalysts. Catalysts speed up chemical reactions, can reduce the energy required for these processes, and in some cases, reactions would not be possible at all without catalysts. Researchers developed a concept that increases the stability of noble-metal catalysts and requires less noble metal for their production.
Published Physicists develop new method to combine conventional internet with the quantum internet
(via sciencedaily.com) Original source Researchers send entangled photons and laser pulses of the same color over a single optical fiber for the first time.
Published Solving the doping problem: Enhancing performance in organic semiconductors
(via sciencedaily.com) Original source Physicists have discovered two new ways to improve organic semiconductors. They found a way to remove more electrons from the material than previously possible and used unexpected properties in an environment known as the non-equilibrium state, boosting its performance for use in electronic devices.
Published Sustainable catalysts: Crystal phase-controlled cobalt nanoparticles for hydrogenation
(via sciencedaily.com) Original source Controlling the crystal phase of cobalt nanoparticles leads to exceptional catalytic performance in hydrogenation processes, scientists report. Produced via an innovative hydrosilane-assisted synthesis method, these phase-controlled reusable nanoparticles enable the selective hydrogenation of various compounds under mild conditions without the use of harmful gases like ammonia. These efforts could lead to more sustainable and efficient catalytic processes across many industrial fields.
Published The next generation of RNA chips
(via sciencedaily.com) Original source An international research team has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient.
Published More electricity from the sun
(via sciencedaily.com) Original source A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.
Published Researchers identify unique phenomenon in Kagome metal
(via sciencedaily.com) Original source A new study focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons -- nanoscale-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.
Published Organic nanozymes have broad applications from food and agriculture to biomedicine
(via sciencedaily.com) Original source Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.
Published Plant-inspired polymers for water purification
(via sciencedaily.com) Original source Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.
Published Optical fibers fit for the age of quantum computing
(via sciencedaily.com) Original source A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published Pioneering measurement of the acidity of ionic liquids using Raman spectroscopy
(via sciencedaily.com) Original source A study has made it possible to estimate experimentally the energy required to transfer protons from water to ionic liquids.
Published 'Miracle' filter turns store-bought LEDs into spintronic devices
(via sciencedaily.com) Original source Scientists transformed existing optoelectronic devices into ones that can control electron spin at room temperature, without a ferromagnet or magnetic field. Researchers replaced the electrodes of store-bought LEDs with a patented spin filter made from hybrid organic-inorganic halide perovskite.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com) Original source Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Better way to produce green hydrogen
(via sciencedaily.com) Original source Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Tackling industrial emissions begins at the chemical reaction
(via sciencedaily.com) Original source Researchers are proposing a new way to curb industrial emissions, by tapping into the 'atomic intelligence' of liquid metals to deliver greener and more sustainable chemical reactions.
Published Researchers discover faster, more energy-efficient way to manufacture an industrially important chemical
(via sciencedaily.com) Original source The reactivity of zirconium on silicon nitride enhances the conversion of propane into propylene, a key commodity chemical needed to make polypropylene. This finding hints at the reactivity researchers might achieve with other nontraditional catalysts.
Published Researchers develop innovative battery recycling method
(via sciencedaily.com) Original source A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published A new way to make element 116 opens the door to heavier atoms
(via sciencedaily.com) Original source Researchers have successfully made super-heavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.
Published Mass layoffs and data breaches could be connected
(via sciencedaily.com) Original source A research team has been exploring how mass layoffs and data breaches could be connected. Their theory: since layoffs create conditions where disgruntled employees face added stress or job insecurity, they are more likely to engage in risky behaviors that heighten the company's vulnerability to data breaches.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com) Original source Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
