Seasonal variations of water-soluble organic carbon, dicarboxylic acids, ketocarboxylic acids, and α-dicarbonyls in Central Himalayan aerosols [PDF]
Atmospheric Chemistry and Physics, 2012 Aerosol samples were collected from a high elevation mountain site (Nainital, India; 1958 m a.s.l.) in the central Himalayas, a location that provides an isolated platform above the planetary boundary layer to better understand the composition of the ...

Analysis of chemical signatures of alkaliphiles using fatty acid methyl ester analysis
Journal of Pharmacy and Bioallied Sciences, 2017 Background: Fatty acids occur in nearly all living organisms as the important predominant constituents of lipids. While all fatty acids have essentially the same chemical nature, they are an extremely diverse group of compounds. Materials and Methods: To

Fe3O4@SiO2–SO3H Nanoparticles: An efficient magnetically retrievable catalyst for esterification reactions [PDF]
Journal of Particle Science and Technology, 2018 In this study, magnetite nanoparticles were obtained from Fe(II) and Fe(III) salts in an alkaline medium. The nanoparticles were then protected from oxidation by a silica shell formed by the sol-gel method using tetraethoxy orthosilicate (TEOS) in an ...

Advanced Robotics Research, EarlyView.To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...

Topology‐Aware Machine Learning for High‐Throughput Screening of MOFs in C8 Aromatic Separation
Advanced Intelligent Discovery, EarlyView.We screened 15,335 Computation‐Ready, Experimental Metal–Organic Frameworks (CoRE‐MOFs) using a topology‐aware machine learning (ML) model that integrates structural, chemical, pore‐size, and topological descriptors. Top‐performing MOFs exhibit aromatic‐enriched cavities and open metal sites that enable π–π and C–H···π interactions, serving as ...
