Adsorption of Methane on Poly Vinyl Alcohol

Journal of the College of Basic Education, 2023
تمت مناقشة دراسات امتزاز غاز الميثان كغاز ملوث بيئي على سطح PVA كأحد التطبيقات الغازية الصلبة وإزالته من الغلاف الجوي. تمت دراسة قدرة الامتزاز لغاز الميثان بمعدل درجات الحرارة 20 و 30 و 40 و 50 درجة مئوية. أوضحت النتائج أن العلاقة بين تركيز الغاز وسعة الامتصاص تخضع لتساوي درجة حرارة Freundlich ، وقد تم حساب قيم a & n بزيادة مع انخفاض درجات الحرارة ،

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

Advanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

Thermochemical Core–Shell Architecturing of Si‐SWCNT Composites for High‐Performance Li‐Ion Battery Anodes

Advanced Science, EarlyView.
A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.
