Multilevel Compositional Characterization of Shea Butter: Fatty Acids, Triacylglycerols, and Unsaponifiable Constituents

ABSTRACT Shea butter is a compositionally complex vegetable fat with a distinct multi‐level lipid composition. In this study, the fatty acid (FA), triacylglycerol (TAG), and unsaponifiable fractions of commercial shea butter were characterized to establish a multi‐level analysis...

Sustainable closed-loop recycling of spent graphite anodes via pre-oxidation and carbon coating

To achieve high-value recovery of graphite anodes from spent lithium-ion batteries, conventional hydrometallurgical and pyrometallurgical routes face environmental and economic bottlenecks, including complex wastewater treatment, high energy consumption and equipment corrosion. T...

Performance evaluation of an earth–air heat exchanger system for temperature and humidity regulation in underground granaries

Underground grain storage facilities benefit from the thermal inertia of surrounding soil, but grain respiration and coupled heat and moisture transfer may induce condensation and mold growth, threatening storage safety. This study experimentally compared conventional mechanical...

Flexible PVDF-HFP Piezoelectric Nanofibers with In Situ rGO and BCZT for High-Sensitivity Tactile Sensing and Haptic-Visual Feedback

Abstract Flexible polymer-based piezoelectric sensors are promising for electronic skin and human–machine interfaces, but challenges remain in achieving efficient electromechanical conversion and sensitive low-pressure detection due to insufficient polarization and weak interfaci...

Valorization of poultry waste into calcium salt of fatty acids (bypass fat): Characterization and techno-economic assessment

Global poultry production generates millions of tons of chicken fat and eggshell waste annually, posing significant solid waste management challenges. To address the environmental burden and underutilization of poultry processing waste, this study integrated waste valorization ap...

Girth Characterization of (3,29)-Regular Bipartite Graphs and Their Associated LDPC Codes

This paper studies a family of (3,29)-regular bipartite graphs introduced by Tanner for low-density parity-check (LDPC) codes. For a prime p≡1(mod87), the graph has 3p left vertices and 29p right vertices. In the associated LDPC code, the right vertices (there are 29p of them, ea...

Antimonate reduction and immobilization driven by pyrite and woodchips-based abiotic and biotic processes

Antimony (Sb) pollution in aquatic environments poses severe threats to ecological safety and human health due to its high toxicity. Four reaction systems were constructed in this study, including a pyrite abiotic reactor (PAR), a pyrite-woodchips abiotic reactor (PWAR), a pyrite...

Preparation of Substituted Phenyl Perfluoro ‐tert ‐butyl Sulfones and Their Use in Nucleophilic Perfluoro ‐tert ‐butylation Reactions

A series of perfluoro‐ tert ‐butyl aryl sulfones are successfully prepared under mild conditions and subsequently employed as reagents for the perfluoro‐ tert ‐butylation of arynes and benzyl bromides, respectively. It is found that the reactions with benzyl bromides generally sh...

Projective Synchronization of Uncertain Linear Systems With Stochastic Perturbations via Discontinuous Adaptive Odd Impulsive Control

ABSTRACT This article studies the discontinuous adaptive odd impulsive control for the projective synchronization of uncertain linear systems with stochastic perturbations. Although the traditional discontinuous adaptive impulsive control can realize system stability, the adaptiv...

Impact of Lactiplantibacillus plantarum on the aerobic deterioration of ensiled total mixed ration inoculated with Pichia kudriavzevii upon aerobic exposure

Ensiling is a common method for preserving total mixed ration (TMR), although exposure to air upon opening often leads to aerobic deterioration associated with fungal community succession. This study evaluated the impacts of Lactiplantibacillus plantarum inoculation during ensili...

Enantiomer-racemate regulated material photoluminescence

Chiral and racemic forms of the same molecular components can adopt distinct molecular packing arrangements, leading to differences in crystal structures, intermolecular interactions, and consequently photophysical properties. This review focuses on how chiral/racemic packing and...

Simplified calculation method for settlement of necking piles accounting for pile-soil interaction in the necking zone

Existing calculation methods often neglect the pile-soil interaction within the necking zone, leading to inaccuracies in predicting the settlement of necking piles. Through transparent soil model tests, the deformation mechanism of the soil around necking piles was investigated....

Hazard assessment of spontaneous plants based on plant diversity: A case study of the Jiahu Archaeological Site, China

This study fills a long-standing research gap in systematic vegetation hazard assessment for Chinese archaeological sites, a field previously dominated by Mediterranean-focused cases. Taking the Jiahu Archaeological Site in Henan as the research object, it explores the correlatio...

PEDOT:PSS-Based OECT Common-Source Amplifiers for Electrophysiological Signal Amplification

Stable amplification of weak electrophysiological signals is important for low-voltage bioelectronic interfaces, but the gain and waveform fidelity of organic electrochemical transistor (OECT)-based amplifiers are strongly influenced by device characteristics and bias conditions....
