The black walnut, Junglas nigra, is indigenous to eastern North America, and abscission of its fruit occurs around October. consists a husk, hard shell, kernel. husk commonly discarded in processing, though it contains phenolic compounds that exhibit antioxidant antimicrobial properties. For this study, walnut husks were extracted using supercritical carbon dioxide with an ethanol modifier. effects temperature, concentration, drying prior extraction upon potential evaluated factorial design...

This investigation rigorously analyzes and introduces a new class of high-performance inorganic solid-state electrolytes, formulated as Ag 7 P 3 X 11 (X = {O, S, Se}), through comprehensive ab initio calculations, highlighting their potential for advanced energy storage technologies.

Chemical surface modification of polymethylmethacrylate (PMMA) and polypropylene (PP) particles was achieved using a continuous atmospheric plasma process, resulting in increased oxidation hydrophilicity. Contact angles treated PMMA ranged from 79–117° (125° for untreated). Air produced higher contact than pure nitrogen, which is attributed to primary degradation oxygen. Higher energy flow rate water resulted decreased angles. Treated PP mixed upon agitation, while untreated remained at the...

By using silicon (Si) as an anode of lithium-ion batteries, the capacity can be significantly increased, but relatively large volume expansion limits application efficient material. Huge during lithiation, however, leads to cracking and losing its connection with current collector. This shortcoming improved by deposition a nanometric carbon- or nitrogen-doped carbon coating on surface, resulting in Si/C-layer Si/C3N4 interfaces. In this work, Li+ diffusion composite materials along three Si...

Abstract Grapes are widely known for health benefits due to their antioxidant content. In wine production, grape stems often discarded, though they has a higher content of antioxidants than the juice. The effectiveness using an environmentally friendly solvent, ethanol, as superheated liquid and supercritical fluid extract compounds from organically grown Crimson Seedless grapes was evaluated. Ferric Reducing Ability Plasma ( FRAP ) assay Total Phenolic Content TPC ), or Folin‐Ciocalteu...

The surfaces of high-density or ultra-high-molecular-weight polyethylenes were hydroxylated using a two-step process. wetting and wear properties the untreated (virgin) surface compared. introduction hydroxyl groups provided an increase in hydrophilicity resulting reduced wear. Hydrophilicity was analyzed by optical analysis water contact angle. Wear determined weight loss under conditions reciprocating pin-on-plate apparatus with panels immersed calf serum. These results suggest that...

A computational fluid dynamics model based on a finite difference solution to mass and momentum conservation equations (Navier–Stokes equations) for liquid droplet transport between two porous or nonporous contacting surfaces (CSs) is developed. The CS dynamic (equation of motion) the spread incompressible available primary surface transfer are coupled with Navier–Stokes equations. topologies inside both (primary CSs) compared experimental data. amount being transferred into CS, predicted by...

The growing energy storage market requires safe and stable high-capacity cycling, silicon (Si) anodes are ideal for this purpose. Electrochemical reactions between Si lithium pose challenges due to the significant volumetric expansion during lithiation. Expansion material can cause cracks in structure result disconnection from current collector. exhibit a variety array of phenomena, such as amorphization crystallization upon full lithiation, with variations depending on crystal orientations....
