Osmium Analysis, Engine Oil Additives and Catalysts: Journal of Modern Chemistry & Chemical Technology 17(3)
By STM Journals ·
This issue of the Journal of Modern Chemistry & Chemical Technology includes four papers on applied chemistry. One reviews spectrophotometric methods for measuring osmium, a rare and toxic metal. One evaluates how additives affect lubricating oils in car engines. One studies a cobalt-molybdenum nitride catalyst for making styrene, and one reviews smart nanomaterials for targeted drug delivery.

Advances in Spectrophotometric Determination of Osmium: Role of Organic Reagents in Trace Analysis and Speciation
Osmium is rare and highly toxic, so measuring it accurately matters. This review evaluates spectrophotometric methods that use organic reagents, including sulfur-containing ligands, azo dyes and flavonoids, and critically discusses a total of 50 reagents.

Evaluation of Additive Effects on Lubricating Oil Properties in Automobile Engines
What do additives do to engine oil? This study compares two commercial lubricating oils with different additive packages, fresh and used at set mileage intervals, and analyses changes in properties such as viscosity, viscosity index and pour point.

Studies on Co-Mo Nitride Incorporated Mesoporous Alumina for the Oxidative Dehydrogenation of Ethylbenzene to Styrene
Oxidative dehydrogenation can convert ethylbenzene to styrene at lower temperatures than the conventional steam process. This study tests 10 and 15 weight percent cobalt-molybdenum nitride on mesoporous alumina as oxidative dehydrogenation catalysts at 873 K, and reports that the 10 percent catalyst gave the higher conversion.

Smart Nanomaterials for Targeted Drug Delivery: Properties, Functionalization and Biomedical Applications
Conventional drug delivery can distribute medicine non-specifically. This review examines the role of smart nanomaterials in targeted drug delivery, covering their properties, functionalisation and biomedical applications. It is a review, not a clinical study.
