Researchers developed a novel approach to convert technical lignin into functional coatings using low-energy suspension plasma spraying (LE-SPS). The new technique eliminates the need for solvents, crosslinkers, or catalysts, and produces continuous and dense coatings with improved UV attenuation and anti-fogging behavior.
Researchers developed a cellulose-based aerogel inspired by white beetles' optical structure, achieving high solar reflectance and infrared emissivity through hierarchical photonic scattering networks. The material achieved daytime subambient cooling of up to 7.1 °C and reduced building energy consumption by 43.5% on average.
Researchers have developed a highly sensitive electronic 'skin' using tiny devices that can measure force applied over an area. This technology has the potential to improve prosthetic limbs and robotic manipulation, allowing robots to accurately track hand movements and grasp delicate objects.
Researchers developed a synergistic structure-doping regulation strategy for lignin-based carbon aerogels using phytic acid, promoting uniform spherical hierarchical structures and dual phosphorus-sulfur doping. This approach achieves high-performance supercapacitors with superior power density and energy storage capabilities.
Researchers have discovered a zero-cost solution to reverse desertification by using food waste nanocellulose extracted from pineapple peels. The material cuts water leakage by 90% and triples phosphate retention, offering a more sustainable alternative to expensive hydrogels.
Researchers developed a gravity-driven biochar microreactor from rattan, achieving ultrahigh flux and complete degradation of common pollutants. The system activated peroxymonosulfate through a non-radical pathway, with boundary-like defects as primary active sites.
Researchers from Tokyo Institute of Technology have developed a novel synthesis method for imine-based COFs, eliminating the need for long reaction times, high temperatures, and Lewis acid catalysts. The method uses an electrogenerated acid as a catalyst, enabling direct fixation of COF films onto electrodes.
Researchers at KAUST have developed a simple technique to create highly porous organic polymers, known as poly(aryl thioether), for applications in photocatalysis and optoelectronics.

Researchers develop cellulose nanofiber plate (CNFP), a sustainable and high-performance material replacing traditional plastics. With exceptional strength, toughness, and thermal dimensional stability, CNFP has the potential to revolutionize industries, including aerospace.
Researchers at UMass Amherst used advanced seismic imaging and data from the National Science Foundation's EarthScope program to construct a detailed model of the tectonic plate beneath the Adirondack Mountains. They discovered a 'pillow' of low-density, relatively light rock material that appears to have been squeezed up under the mou...
Researchers adapted rock imaging methods to study fungi on paper, revealing that fungi grow similarly to mushrooms and can be embedded within paper fibers. This new insight enables conservators to develop effective conservation strategies for paper artefacts.
University of Pittsburgh researchers design a family of ultra-porous materials with potential applications in drug delivery, gas storage, and industrial separations. The materials' high porosity could enable more efficient pharmaceutical delivery into the human body and lower-cost industrial separations.
Researchers from Kiel University and Hamburg University of Technology have developed Aerographite, a three-dimensionally interwoven porous carbon tube material that is incredibly strong yet extremely light. The material has unique properties, including being electrically conductive, ductile, and non-transparent.
Scientists at Rensselaer Polytechnic Institute created a coating with low-density, vertically-aligned carbon nanotube arrays that absorb more than 99.9 percent of light, making it the darkest material ever made by man. This breakthrough could lead to improved solar energy conversion and detection capabilities.
