In International Journal of Extreme Manufacturing, researchers used a carefully tuned femtosecond laser under water immersion to etch nanogratings just 46 nanometers apart with groove widths near 13 nanometers onto highly oriented pyrolytic graphite (HOPG). It addresses a long-standing challenge: fabricating uniform structures smaller than 100 nanometers.

Ce-MOFs based solid frustrated Lewis pairs (FLPs) were designed via a competitive coordination strategy using single-carboxylate ligands. Functional groups (–NH₂, –OH, –Br, –NO₂) modulate the Ce–CUS/Ce–OH acid–base sites, enhancing H₂ heterolytic cleavage through a “push-pull” effect. The optimized MOF-808-NH₂ achieves complete conversion of styrene and dicyclopentadiene at 100 °C and 2 MPa, providing an efficient pathway for green olefin hydrogenation catalysis.

Journal of Bioresources and Bioproducts reports a 1 000-L process that converts 20 % solids corn stover into 10.6 g L⁻¹ Rhodosporidium toruloides lipids. After 80-day 6 % NaOH ambient storage, one-hour steam and cloth-squeeze detox, the fed-batch fermentation achieves 93.6 % total reducing-sugar recovery and a palm-oil-like fatty-acid profile without centrifuges, demonstrating scalable, low-energy microbial oil production from agricultural waste.

Researchers have discovered a powerful synergy between gold, manganese, and copper that could transform the way we produce valuable chemicals. By supporting tiny gold nanoparticles on a specially designed perovskite material (LaMn_0.75Cu_0.25O₃), the team achieved an impressive 95% yield of acetaldehyde from ethanol at just 225 °C, a major step toward cleaner, more efficient chemical processes. The secret lies in the smart use of copper. A small amount of Cu dramatically improves the catalyst by creating active sites that speed up the toughest step in the reaction. But there’s a catch: too much copper destabilizes the system, reducing efficiency. This delicate balance highlights the importance of atomic-level design in next-generation catalysts for sustainable chemical manufacturing.

Radiative cooling systems (RCSs) possess the distinctive capability to dissipate heat energy via solar and thermal radiation, making them suitable for thermal regulation and energy conservation applications, essential for mitigating the energy crisis. A comprehensive review connecting the advancements in engineered radiative cooling systems (ERCSs), encompassing material and structural design as well as thermal and energy-related applications, is currently absent.

MXene-based smart contact lenses demonstrate a cutting-edge advancement in wearable ophthalmic technology, combining real-time biosensing, therapeutic capabilities, and user comfort in a single platform. These devices take the advantage of the exceptional electrical conductivity, mechanical flexibility, and biocompatibility of two-dimensional MXenes to enable noninvasive, tear-based monitoring of key physiological markers such as intraocular pressure and glucose levels. Recent developments focus on the integration of transparent MXene films into the conventional lens materials, allowing multifunctional performance including photothermal therapy, antimicrobial and anti-inflammation protection, and dehydration resistance. These innovations offer promising strategies for ocular disease management and eye protection. In addition to their multifunctionality, improvements in MXene synthesis and device engineering have enhanced the stability, transparency, and wearability of these lenses. Despite these advances, challenges remain in long-term biostability, scalable production, and integration with wireless communication systems. This review summarizes the current progress, key challenges, and future directions of MXene-based smart contact lenses, highlighting their transformative potential in next-generation digital healthcare and ophthalmic care.

As global demand for green hydrogen grows, scientists are exploring direct seawater electrolysis as a sustainable way to produce hydrogen without consuming scarce freshwater. Yet, seawater contains abundant chloride ions, which corrode electrodes and drastically shorten device lifetimes — a major barrier to commercialization.

Ru-Co/ZrO₂ single-atom alloy catalyst was developed for alcohol amination, which exhibited satisfactory yields to primary amines for a broad scope of substrates. The synergistic effect between Ru and Co was demonstrated by the significantly higher turnover rate and yield to primary amine than those on Co/ZrO₂ and Ru/ZrO₂. This study opens a new avenue to the design of low-cost and efficient catalysts for alcohol amination.

A team of researchers in China has developed a new low-cost biochar material that can efficiently remove persistent metal complexes from water, offering a promising tool for improving water quality and environmental safety.
