However, the level of GSAC decreases significantly during the processing of black garlic, and the pathways and degradation products resulting from this decline remain unclear. To investigate the potential transformation mechanisms of GSAC in black garlic, simulation systems for thermal decomposition, Maillard reactions, and enzymatic hydrolysis were established.

Carboxylated cellulose nanocrystals mediated flower-like zinc oxide for antimicrobial without activation of light.

Conventional light-driven antimicrobial strategies of zinc oxide (ZnO) are limited by inadequate illumination in dark environments. In this study, carboxylated cellulose nanocrystals (MCNC) mediated flower-like ZnO (C@Z) with self-promoted reactive oxygen species release under dark is fabricated. The adsorption of Zn ions on MCNC prompts the growth of ZnO along the (002) crystal plane, forming a flower-like hybrid with superior dispersibility and oxygen vacancies compared to MCNC-free ZnO, which exposes the (100) plane.

Deciphering the Sulfur-Involved Bonding Interactions in Sulfurized Polyacrylonitrile: The Formation Thermodynamics and the Roles in Electrochemical Characteristics.

Sulfurized polyacrylonitrile (SPAN) exhibits a very high cycle stability by overcoming the shuttle effect of conventional Li-S batteries. However, there are still controversies in SPAN about the bonding types of sulfur with the matrix, their critical synthesis temperature regions, and their roles in the electrochemical lithium storage reaction, seriously hindering the economical synthesis of SPAN, the optimization of performances, and the exploration of other SPAN-like alternatives. The key to solving the above problems lies in accurate measurements of the thermodynamic evolution of bonding interactions in the synthesis process as well as in the electrochemical process.

Ultrathin MWCNT/TiCT Hybrid Films for Electromagnetic Interference Shielding.

The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit the application of electromagnetic interference (EMI) shielding. In this work, an ordered lamellar assembly structure of multiwalled carbon nanotube/TiCT (MWCNT/TiCT) hybrid films was achieved by vacuum-assisted filtration through the hybridization of TiCT nanosheets and carbon nanotubes, where carbon nanotubes were tightly sticking on the surface of TiCT nanosheets via physical adsorption and hydrogen bonding. Compared with the pure carbon nanotubes films, the hybrid MWCNT/TiCT films achieved a significant improvement in conductivity of 452.

"May we be the bridge and boat to cross the water": Community-engaged research on metta meditation.

Inclusive research is needed to understand how contemplative practices are used by people of diverse identities. Metta meditation-also known as loving-kindness meditation-may be particularly relevant for people committed to equity and justice because of the social nature of the practice. Using community-based participatory research and an intersectional framework, we assessed how people in a diverse meditation community teach and practice metta meditation.

Solvent-Dependent C(sp)-CF Reductive Elimination from Neutral Four-Coordinate Cu(III) Complexes.

A solvent dependent C(sp)-CF bond-forming reductive elimination from neutral four-coordinate Cu(III) complexes [(L)Cu(CF)(CHCO Bu)] (L=pyridine or its derivatives) is described. Reactions in less polar solvent ClCHCHCl proceed via a concerted bond breaking/bond forming process along with the reorientation of the ligand, while reaction in polar solvent DMF occurs via a rate limiting ligand-dissociation, followed by C(sp)-CF reductive elimination from the resulting three-coordinate intermediate. These mechanistic proposals are supported by kinetic studies that included ligand and temperature effects, as well as DFT calculations.

Virus-mediated delivery of single-chain antibody targeting TDP-43 protects against neuropathology, cognitive impairment and motor deficit caused by chronic cerebral hypoperfusion.

Chronic cerebral hypoperfusion induced by permanent unilateral common carotid artery occlusion in mice was recently found to induce an age-dependent formation of insoluble cytoplasmic TDP-43 aggregates reminiscent of pathological changes found in human vascular dementia. In this model, the gradual deregulation of TDP-43 homeostasis in cortical neurons was associated with marked cognitive and motor deficits. To target the TDP-43-mediated toxicity in this model, we generated an adeno-associated virus vector encoding a single-chain antibody against TDP-43, called scFv-E6, designed for pan-neuronal transduction following intravenous administration.
