Summary: In this study, a dual modification approach was employed to improve the removal efficiency of volatile organic compounds (VOCs) using metal-organic framework (MOF) MIL-101(Cr) powder. The first modification involved crystallizing MIL-101(Cr) on the surface of amine grafting macroporous polyacrylate (PA-NH2) spheres, resulting in smaller crystal size. The second modification involved the synthesis of a hydrophobic composite P-MIL-101(Cr)@PA-NH2 using chemical vapor deposition (CVD) with polydimethylsiloxane (PDMS). The modified material exhibited excellent adsorption performance and structural stability, making it highly promising for VOC capture.

Summary: The researchers report an activatable antimicrobial nanoplatform with ultralow-background persistent luminescent (PL) turn-on imaging and therapeutic capability. The platform utilizes chitosan as a linker to immobilize copper ions on the surface of persistent luminescent nanoparticles (PLNPs) to fabricate PLNPs-CS-Cu2+. The PL emission of PLNPs is quenched by Cu2+ under physiological conditions but recovered due to the conversion of Cu2+ into Cu+ by high glutathione (GSH) levels at the infection site. The as-prepared antibacterial nanoplatform shows promise for highly sensitive persistent luminescent imaging and simultaneous treatment of bacterial infection.

Summary: Ball milling is effective in activating and reducing the size of microscale zero valent iron (mZVI) and sulfidating mZVI mechanochemically. However, there are differences in the interaction between chlorinated ethenes (CEs) and ball milled mZVI (mZVIbm) and mechanochemically sulfidated mZVI (S-mZVIbm) that are not well understood. This study found that simple ball milling exposed active Fe0 sites, while mechanochemical sulfidation decreased Fe0 sites and increased S2 sites. The sulfidation process enhanced the reactivity of TCE dechlorination the most, followed by PCE and 1,1-DCE, but reduced the reactivity of trans-DCE, cis-DCE, and VC compared to simple ball milling. Sulfidation also improved the electron efficiency of CE dechlorination, except for cis-DCE and VC. The kSA of cis-DCE, VC, and trans-DCE dechlorination positively correlated with the sulfide content.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
