Researchers showed that recycled PET can be combined with 10 wt% waste cellulosic fibers to produce usable composites, provided processing conditions limit thermal degradation. Performance depended strongly on the PET feedstock, with the TiO2-containing grade showing the smallest losses in molecular weight, strength, and ductility.
Researchers developed a method to grow multilayer graphene-like networks directly on nickel powder using sucrose and rapid thermal annealing, then consolidated the material by spark plasma sintering. Under selected processing conditions, the resulting nickel composites showed higher strength, hardness, and fracture elongation than pure nickel while retaining a well-bonded carbon network.
Researchers used ultrasound-assisted carbonation to control water confinement in fresh cement paste, producing a highly refined pore network with 96.8% of pores below 200 nm. The resulting paste combined high specific compressive strength, greater high-frequency sound transmission loss, strong strength retention after water saturation, and cumulative CO2 uptake of 7.11% of cement mass after 28 days.
The start of a new battery materials library could pave the way for future AI models to help scientists design sodium-ion batteries that charge faster, last longer and store more energy, according to new research from the University of Surrey.
To build faster and more energy-efficient computers, researchers need to understand nanoscale magnetic materials. But looking inside these tiny magnets is surprisingly difficult: modern microscopes only measure the magnetic field outside the material, not the magnetic pattern inside. Because many different internal patterns can produce the exact same field, working backwards has long been a challenge.
The Korea Research Institute of Standards and Science (KRISS, President Dr. Ho Seong Lee) has re-measured a key transition frequency of the strontium (Sr) atom for the first time in 88 years since 1938, using a photonic grating chip, and has established a new absolute frequency value with a measurement uncertainty reduced by more than 50 times.
The Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) has joined BioMADE, a national institute focused on advancing manufacturing using biological systems in the United States, strengthening connections between ORNL research, industry needs and pathways to commercial-scale production of new chemicals and materials.
Large quantities of acrylic glass are used worldwide in a wide range of applications, from window panes and car tail lights to furniture. The polymer is also known by the brand name Plexiglas.
Researchers demonstrated a proof-of-concept method for machining silicon with a single 30-femtosecond extreme ultraviolet pulse, producing reproducible micrometer-scale craters with sub-micrometer widths under selected conditions. Simulations captured the dose-dependent trend but underestimated crater size, while the experiments point to possible future uses in maskless semiconductor processing and photomask fabrication.
The Advanced Research + Invention Agency (ARIA) has today announced it is backing 11 new research projects (Creators) with £50 m to develop new ways of manufacturing advanced materials at scale using proteins, as part of its Universal Fabricators program.
