As the world searches for practical ways to reduce carbon dioxide emissions, scientists are developing catalysts that can transform CO2 from a climate concern into a useful industrial resource. A study published in Biochar reports a coconut shell-derived biochar catalyst that efficiently converts CO2 into carbon monoxide, an important building block for producing fuels, chemicals, methanol, olefins, and polymers.

Researchers have developed a light-driven catalyst made from two common waste materials, discarded PET plastic bottles and orange peels, that can efficiently break down acetaminophen in water. The study, published in Biochar, presents a sustainable strategy that links plastic upcycling with advanced water treatment.

Scientists at the U.S. Department of Energy's Oak Ridge National Laboratory have developed a method that uses additive manufacturing, or 3D printing, to fabricate custom canisters for powder metallurgical hot isostatic pressing, streamlining production of large-scale metal components used in aerospace, energy and medical applications.

The team of Yanjun Jiang from Hebei University of Technology has constructed an efficient asymmetric reduction system for the synthesis of chiral alcohols by coupling electrochemical coenzyme regeneration with immobilized enzymes.

Researchers have reviewed recent advances in electrocaloric (EC) cooling devices, highlighting their potential as compact, energy-efficient alternatives to conventional refrigeration technologies. The study, published in the open-access journal Thermo-X, summarizes the latest developments in device architectures, thermodynamic cycles, and performance evaluation methods for electrocaloric cooling systems.

This study highlights a practical formulation strategy to enhance the skin penetration of 10-hydroxy-2-decenoic acid (10H2DA), a key bioactive compound in royal jelly. By incorporating anionic cross-linked polymers, the authors achieved more than a tenfold increase in 10H2DA permeation compared with royal jelly extract alone. The study further confirmed epidermal penetration using DESI imaging mass spectrometry and demonstrated that higher skin hydration strongly promotes 10H2DA delivery. These findings emphasize that both formulation design and skin condition are critical for improving the dermal delivery of low-molecular-weight amphiphilic compounds.

A study shows how a modified form of biochar can help microbial biofilms break down stubborn dye pollutants in wastewater, offering a promising strategy for cleaner and more stable anaerobic treatment systems.

As the world searches for cleaner ways to store and convert energy, scientists are turning to an unlikely source of high-performance materials: biomass. A review published in Biochar examines how biomass-derived materials, especially biomass-derived carbon materials, are being developed for energy storage devices and electrocatalytic energy conversion systems, including supercapacitors, fuel cells, water electrolysis, and carbon dioxide reduction.
