Jasmonic acid's impact on Sedum alfredii growth and cadmium tolerance: A physiological and transcriptomic study.

Soil cadmium (Cd) pollution is escalating, necessitating effective remediation strategies. This study investigated the effects of exogenous jasmonic acid (JA) on Sedum alfredii Hance under Cd stress, aiming to enhance its phytoextraction efficiency. Initially, experiments were conducted to assess the impact of various concentrations of JA added to environments with Cd concentrations of 100, 300, and 500 μmol/L.

High-efficiency adsorption of phenanthrene by FeO-SiO-dimethoxydiphenylsilane nanocomposite: Experimental and theoretical study.

Phenanthrene (PHE), as one of representative polycyclic aromatic hydrocarbons (PAHs) can cause serious adverse effects on human health, developing effective adsorbents to alleviate PHE contamination is in urgent demand. A novel FeO-SiO-Dimethoxydiphenylsilane (FeO-SiO-2DMDPS) nanocomposite was fabricated from encapsulation and grafting process. Magnetic FeO nanoparticles were served as preliminary matrix material, SiO was used to link the magnetic oxide and provide hydroxyl groups for proceeding the silane coupling reaction subsequently, and the aromatic rings in DMDPS could provide active sites for PHE adsorption via π-π interaction.

GC analysis of black gel pen ink stored under different conditions.

In many criminal and civil cases in China, the most commonly questioned documents are those written with gel pen ink. An important task for forensic document examiners is to identify whether two or more ink entries in one or more documents were written with the same ink type. The identification of the age of gel ink entries made poses an important and difficult problem for forensic document examiners.
