In the Journal of Renewable and Sustainable Energy, researchers in Taiwan — where expanding renewable energy is challenging given its limited size and geographical constraints — compared land-based solar farms and the island nation’s first large-scale commercial offshore floating photovoltaic installation. They found that offshore systems can generate more electricity over their lifetime, possibly because of the cooling effect of the surrounding water. The study yielded comprehensive insights into the carbon footprint of both types of systems, offering guidance for mitigating CO2 emissions.

Ice-nucleating proteins naturally bind only to organic surfaces, so understanding whether they can bind to human-made materials can help with applications like deicing, creating artificial snow, cryo-medicine, and more. In Biointerphases, researchers found that the proteins connect to a surface in a layer of single molecules with their ice formation side facing out, allowing ice to grow atop the surface, and that they do not seem to care what type of material they are binding to; for both artificial and natural surfaces, the INPs bind in remarkably similar ways.

A new study led by Dr Lin Su of Queen Mary University of London, published today in the Journal of the American Chemical Society, describes a new integrated solar reactor in which engineered Escherichia coli (E. coli) are grown directly inside the same liquid that converts CO₂ into a usable energy source using sunlight. In future, this technology may be used to make environmentally clean chemicals, plastics or even microbial protein.   

SAN ANTONIO — May 19, 2026 — Southwest Research Institute (SwRI) has achieved ISO 14001:2015 certification for its fire technology, pharmaceutical development, analytical and environmental chemistry, and chemical engineering research areas. The internationally recognized environmental management framework supports proactive systems and operations to reduce emissions and protect the environment.

Electrocatalytic nitrite reduction reaction (NO₂⁻RR) to synthesize ammonia (NH₃) has been constrained by sluggish kinetics of water dissociation and the weak adsorption of nitrite. In this work, we develop an in-situ reconstruction strategy that transforms Ni-doped BiO_2-x (NiBiO_2-x) to Bi/NiBiO_2-x, which exhibits excellent activity and selectivity for NO₂⁻RR to synthesize NH₃. Diverse ex-situ and in-situ characterizations reveal potential-driven structural transformation from NiBiO_2-x to Bi/NiBiO_2-x, which features dual Ni²⁺-Bi⁰ active sites. The Ni²⁺ site is able to reduce the water dissociation barrier from 0.79 to 0.41 eV, while concurrently the Bi⁰ site can strengthen NO₂⁻ adsorption to promote *NO₂H intermediate formation. Consequently, the in-situ constructed Bi/NiBiO_2-x catalyst with Ni²⁺-Bi⁰ catalytic pairs enable an excellent NO₂⁻RR performance, achieving a NH₃ Faradaic efficiency (FE_NH3) of 94.5% at −0.6 V vs. RHE. The present study opens the new direction to in-situ construct high-performance electroreduction catalysts for small molecule synthesis.

A new scientific review reveals how click chemistry—a highly efficient chemical approach—is transforming oncology by merging accurate diagnosis with precision therapy into a single system. 

A team at the University of Vienna, led by chemist Nuno Maulide, has developed a groundbreaking method for controlling chemical reactions in a more targeted and efficient manner. At the heart of this is the concept of 'cation sampling': specially selected groups (ketones), in a sense, function as molecular signposts for randomly migrating positive charges, enabling reactions to take place at sites on a molecule that were previously difficult to access. The method allows carbon-hydrogen bonds (C–H bonds) to be specifically modified. The study was published in the prestigious Journal of the American Chemical Society. 

A low-Tg chalcogenide-glass adhesive (As-S(Se)-I, Tg = 8.85 ℃, n≈2.1) is presented that bonds at 120 ℃, wets interfaces, fills gaps, and cools into a robust glass bonding layer. It lifts transmission to a maximum of 91%, reduces reflection to 4.8% (from 58.5%), increases the laser-damage threshold by >59%, and enables 11.7 W delivery from endcap fiber, providing a universal, thermoplastic yet stable route to compact, high-power, thermally reliable mid-IR photonic systems.

Linzhi Yu et al. have developed compact metasurface operators for all-optical image processing, enabled by double-phase encoding and polarization multiplexing. This ultrathin nanophotonic platform performs real-time light field transformations, including edge detection, object recognition, and volumetric holography. The work introduces new possibilities for ultra-compact, energy-efficient analog computing systems, with potential applications in imaging, sensing, and holographic displays.
