Eco-friendly antioxidant carboxymethyl cellulose /pectin films incorporating oregano essential oil and vanillic acid for tomato shelf-life extension.

The widespread use of conventional non-degradable packaging films for fruit preservation has led to serious environmental concerns, highlighting the urgent need for sustainable, biodegradable, and multifunctional packaging materials. Herein, we developed a carboxymethyl cellulose/pectin/oregano essential oil/vanillic acid (CMC/pectin/OEO/VA) film, in which hydrogen bonding between CMC and pectin hydroxyl groups enhances structural integrity and mechanical properties, further strengthened by VA, while phenolic compounds such as carvacrol and thymol in OEO provide antioxidant and antimicrobial functions. The optimized CMC/Pectin/OEO/VA0.

Multi-layered smart film based on anthocyanin-citric acid complex for real-time meat freshness monitoring.

Synergistic CuO@Ni(OH) Core-Shell Electrocatalyst for High-Efficiency Nitrate Reduction to Ammonia.

The electrocatalytic reduction reaction of nitrate (NORR) is anticipated to convert nitrogen-containing pollutants into valuable ammonia products. Copper-based catalysts have received great attention because of their good performance in the NORR due to the strong binding energy with *NO intermediates. However, the poor HO dissociation ability of Cu is unable to provide H in time for the hydrogenation reaction of NO, thus hindering the electroreduction of the NO.

Carboxymethyl cellulose/polyvinyl alcohol-based antioxidant film strengthened by physical/chemical bonding of cinnamaldehyde-tannin-metal nanoparticles.

Carboxymethyl cellulose (CMC) is a potentially biodegradable substrate widely used in antioxidant food packaging films. However, the rigid structure and large number of hydroxyl groups of CMC films result in poor mechanical properties and are prone to hygroscopicity, which limits their practical application. In this study, we developed a self-assembled multifunctional cinnamaldehyde-tannin-metal composite nanoparticle (CIN-TA metal nanoparticle) that coats cinnamaldehyde via catechol bonds between metal ions and tannic acid to form nanocomposites that produce physical and chemical crosslinks with the CMC matrix.

Interface Energy-Level Reorganization for Efficient Perovskite γ-Ray Detectors.

Metal halide perovskites are promising candidates for gamma-ray (γ-ray) spectrum detectors. However, achieving high-resolution energy spectra in single-photon pulse-height analysis mode remains challenging, due to the inevitable leakage currents degrade the recognizable fingerprint energies which is critical for resolving γ-ray spectroscopy. We demonstrate under high bias voltage, a deficient contact barrier can lead to excessive surface charge injection, thereby increasing leakage current from electrodes to perovskites.

Structural design of FeCo alloy implanted into N,S co-doped carbon nanotubes self-catalyzed growth for advanced liquid and flexible all-state-state Zn-air battery.

The introduction of transition bimetallic alloys can effectively improve oxygen reduction reaction (ORR) activity. However, the alloy particles are inclined to dissolve under harsher conditions, resulting in a serious decrease in catalytic activity and stability. Herein, an efficient ORR catalyst, FeCo alloy nanoparticles (NPs) encapsulated in N,S co-doped carbon nanotubes (FeCo-NSCNTs), was developed through a self-catalyzed growth strategy.

Single-Atom Zinc Sites with Synergetic Multiple Coordination Shells for Electrochemical H O Production.

Precise manipulation of the coordination environment of single-atom catalysts (SACs), particularly the simultaneous engineering of multiple coordination shells, is crucial to maximize their catalytic performance but remains challenging. Herein, we present a general two-step strategy to fabricate a series of hollow carbon-based SACs featuring asymmetric Zn-N O moieties simultaneously modulated with S atoms in higher coordination shells of Zn centers (n≥2; designated as Zn-N O -S). Systematic analyses demonstrate that the synergetic effects between the N O species in the first coordination shell and the S atoms in higher coordination shells lead to robust discrete Zn sites with the optimal electronic structure for selective O reduction to H O .

Synthesis-on-substrate of quantum dot solids.

Perovskite light-emitting diodes (PeLEDs) with an external quantum efficiency exceeding 20% have been achieved in both green and red wavelengths; however, the performance of blue-emitting PeLEDs lags behind. Ultrasmall CsPbBr quantum dots are promising candidates with which to realize efficient and stable blue PeLEDs, although it has proven challenging to synthesize a monodispersed population of ultrasmall CsPbBr quantum dots, and difficult to retain their solution-phase properties when casting into solid films. Here we report the direct synthesis-on-substrate of films of suitably coupled, monodispersed, ultrasmall perovskite QDs.
