Exploration of high-value pathways for lignin: From catalyst preparation to product development.

Considering the facts of fossil fuel depletion and environmental issues, the conversion of biomass into high value-added chemicals is of great importance. In this work, Ni and Co were encapsulated in lignin-derived phenolic resin spheres to obtain NiCo@LRS, which was then employed as a sacrificial template for the synthesis of the bimetallic catalyst NiCo@LC-RS. The Ni and Co act as the acid and dehydrogenation sites for the catalytic transfer hydrogenolysis of 2-phenoxy-1-phenylethanol (pp-ol) and corncob lignin, respectively, and exhibit a synergistic enhancement effect.

MiR-124 Delivered by Extracellular Vesicles from Mesenchymal Stem Cell Exerts Neuroprotective Effects by Stabilizing the p62-Keap1-Nrf2 Pathway after Spinal Cord Injury in Rats.

Spinal cord injury (SCI) can cause irreversible trauma to nervous tissue, leading to permanent damage to the patient's motor and sensory functions. Extracellular vesicles derived from mesenchymal stem cells (MSC-EVs) can simulate most of the functions of MSCs and are considered an ideal treatment option for SCI. However, the potential mechanism of MSC-EVs treatment for SCI still needs to be explored.

Conversion of α-linolenic acid into n-3 long-chain polyunsaturated fatty acids: bioavailability and dietary regulation.

N-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs) are essential for physiological requirements and disease prevention throughout life but are not adequately consumed worldwide. Dietary supplementation with plant-derived α-linolenic acid (ALA) has the potential to rebalance the fatty acid profile and enhance health benefits but faces challenges such as high β-oxidation consumption, low hepatic conversion efficiency, and high oxidative susceptibility under stress. This review focuses on the metabolic fate and potential regulatory targets of ALA-containing lipids , specifically the pathway from the gastrointestinal tract to the lymph, blood circulation, and liver.

Tuning the Interfacial Deformation of Gliadin-Flaxseed Gum Complex Particles for Improving the Foam Stability.

Gliadin nanoparticle (GNP) is a promising foaming agent, but its application is hindered by the limited foam stability under low acidic conditions. Herein, we attempted to tune the foam stability of GNP by coating it with flaxseed gum (FG) and investigated the structure, interfacial behaviors, and foam functionality of gliadin-FG (GFG) particles at pH 4.5.

Contaminant-free layer-by-layer annealing to improve the properties of HfO/SiO optical films for the fs laser.

The low laser-induced damage threshold (LIDT) of HfO/SiO films is an important factor in limiting the further development of high repetition rate femtosecond (fs) laser systems. Conventional whole-layer annealing can effectively improve the properties of SiO films, but it is difficult to improve the properties of HfO films located in the intermediate layer and is also prone to introduce contaminants. In this study, an innovative magnetron sputtering-vacuum tube furnace combined system was presented to deposit and anneal the HfO/SiO films without contaminant.

Spatial differentiation and influencing factors of heavy metals in soils of typical counties in Lhasa river basin.

This paper studied the spatial distribution and influencing factors of heavy metals (HMs) such as Cu, Pb, Zn, Cr, Ni, Cd and As in the soil of Linzhou County in the Lhasa River basin. By collecting 504 surface soil samples, using descriptive statistics, Kriging interpolation and geoaccumulation index methods, combined with the geographic detector model, the spatial distribution characteristics of soil HMs content and its interaction with 19 environmental factors were systematically analyzed.The results showed that the content of heavy metals in the soil in this area was generally higher than the background value of soil in Lhasa, especially Cd and As, which showed strong spatial heterogeneity, suggesting the existence of specific pollution sources.

Preparation of cellulose-based nanoparticles via electrostatic self-assembly for the pH-responsive delivery of astaxanthin.

Oral administration of astaxanthin (AST), a potent antioxidant, is limited owing to its low solubility, physicochemical stability, and bioavailability. This study developed pH-responsive nanocarriers by the electrostatic self-assembly of 2,2,6,6-tetramethylpiperidine-1-oxyradical (TEMPO)-oxidized cellulose nanofibers (TCNFs) and chitosan (CS) to enhance the intestinal delivery of AST. The TCNF/CS@AST nanoparticles were optimized through single-factor experiments and Box-Behnken design, subsequently overcoming the hydrophobicity of AST and demonstrating improved stability against environmental stressors and controlled release in the intestinal environment.

Design of an Oxide Monolayer with High by a Strong Anharmonicity Unit.

In this paper, a new strategy to obtain a transition-metal oxide (TMO) thermoelectric monolayer is demonstrated.

Specifically, the transition-metal atom in the XO (X = Ti, Zr, Hf) monolayer is replaced by the [Ag] cluster and a stable structure AgO is achieved.
