Although triboelectrification is a well-known phenomenon, fundamental understanding of its principle on a material surface has not been studied systematically. Here, we demonstrated that the surface potential, especially the surface dipoles and surface electronic states, governed the triboelectrification by controlling the surface with various electron-donating and -withdrawing functional groups. The functional groups critically affected the surface dipoles and surface electronic states followed by controlling the amount of and even the polarity of triboelectric charges. As a result, only one monolayer with a thickness of less than 1 nm significantly changed the conventional triboelectric series. First-principles simulations confirmed the atomistic origins of triboelectric charges and helped elucidate the triboelectrification mechanism. The simulation also revealed for the first time where charges are retained after triboelectrification. This study provides new insights to understand triboelectrification.

Machine learning algorithms have proven to be effective for essential quantum computation tasks such as quantum error correction and quantum control. Efficient hardware implementation of these algorithms at cryogenic temperatures is essential. Here we utilize magnetic topological insulators as memristors (termed magnetic topological memristors) and introduce a cryogenic in-memory computing scheme based on the coexistence of a chiral edge state and a topological surface state.

Bioaugmented slurry technology is a sustainable remediation technology for PAHs-contaminated soil. However, the lack of experimental data on the remediation of complex, actual contaminated soils has hindered the practical application of this technology. This study explored the bioaugmented degradation of PAHs using actual soil slurry with and without the addition of microbial agents in the microscopic world.

Ethnopharmacological Relevance: The Chinese medicine sappanwood is primarily sourced from the dried heartwood of the medicinal plant Caesalpinia sappan Linn., which has been found with a variety of valuable properties including anti-inflammatory, anti-oxidant, and anti-viral effects. Preliminary investigations have demonstrated that sappanwood showed strong anti-SARS-CoV-2 M effects, but the key constituents responsible for SARS-CoV-2 M inhibition and their anti-M mechanisms have not been uncovered.

This study aimed to develop bead-free nanofibers for effective omega-3 encapsulation using optimal mixing ratios of whey protein isolate (WPI)/polyvinyl alcohol (PVA) blends via electrospinning method. Various WPI-PVA ratios (100:0, 90:10, 80:20, 70:30, 60:40, 50:50 v/v) were examined for surface tension, viscosity, and conductivity. SEM images revealed uneven nanofibers with bead at 90:10 and 80:20 ratios, while the 70:30 ratio produced uniform and bead-free nanofibers with an average diameter of 262.

This study focuses on the development of an efficient membrane-based clarification process to enhance the performance of subsequent ultrafiltration and produce high-quality sweet lime juice. A range of casting solutions were prepared using a blend of pore-forming polymers, including polyvinylpyrrolidone (PVP), polyvinylidene fluoride (PVDF), and cellulose acetate (CA), dissolved in dimethylformamide (DMF) solvent through the phase inversion technique. To further enhance the membrane's performance, four biopolymers poly (lactic acid) (PLA), xanthan gum, chitosan, and gelatin were incorporated, with and without clay, to refine its structure, porosity, and surface properties.
