Summary: The dilemma of fossil fuel use, political versatility, and global climate change have led to a growing interest in renewable energy and green chemical technologies. Glycerol, a by-product of biodiesel production, has gained attention for its low cost and potential as a renewable green chemical building block. This study proposes a conceptual design of integrated glycerol hydrogenolysis with on-site hydrogen produced from glycerol reforming, which shows promising economic potential and environmental benefits in producing high-value chemicals derived from glycerol.

Summary: Glycerol, a co-product in the biodiesel process, can be used as a raw material in a biorefinery scheme. Studies have been conducted to selectively reduce and oxidize glycerol, as well as steam reform it, to produce valuable chemicals and energetic compounds. The integration of these processes into a biorefinery framework has been demonstrated. The conversion of glycerol to various compounds such as propylene glycol, ethylene glycol, hydrogen, dihydroxyacetone, lactic acid, syngas, carbon dioxide, and methane shows the potential of utilizing glycerol in expanding biorefinery schemes.

Summary: This study assessed the use of two glycols and their mixtures in microemulsions and found that the composition and viscosity of microemulsions can be changed by quantifying glycols. The selected oils and glycols composition resulted in microemulsions with reduced surfactant content and improved safety as delivery systems.

Summary: MXenes have promising applications due to their two-dimensional nature and adjustable functional groups. However, their fast degradation caused by dissolved oxygen and water molecules hinders their practical use. To address this issue, the researchers introduced glycerol as a protective agent for MXene suspension, achieving long-term storage.

Summary: The study focuses on nanofluids consisting of propylene glycol, water, and dispersed graphene nanopowder. Nanofluids were prepared by mixing propylene glycol and water in ratios of 100:0, 75:25, and 50:50. The main objective is to investigate the tribological behavior of nanofluids using a pin-on-disc device. The effects of load on wear, coefficient of friction, and frictional force were examined, revealing a reduction in wear, friction coefficient, and frictional force for most samples with increasing load, but an increase for some samples.

Summary: The use of electronic cigarettes by young adolescents has dramatically increased in recent years, with manufacturers adapting to make them more appealing to this demographic. However, research is beginning to show that e-cigarette use can have negative effects on cardiac function, vascular integrity, and cardiometabolic health. It is important to have a comprehensive understanding of these effects in order to inform policymakers of the dangers associated with e-cigarette use.

Summary: Hydrogels with OEG, OPG, and combined OEG/OPG pendant chains were synthesized and their properties were investigated. An optimized method for OPGMA synthesis was developed. PEG6MA, PPG5MA, and P(EG6/PG5)MA hydrogels were produced using gamma radiation-induced polymerization. The combination of OEG and OPG allowed easy tuning of the phase transition temperature, making it suitable for biomedical applications.

Summary: A novel route for the sustainable synthesis of Vinyl Methyl Ether (VME) from biomass-derived ethylene glycol dimethyl ether (EGDE) catalyzed by CaO-MgO catalyst at atmospheric pressure has been reported. The strongly basic sites on CaO-MgO surfaces facilitated the formation of VME, achieving high efficiency and stability. This work provides a viable and sustainable strategy for the synthesis of VME and other high-value vinyl compounds from biomass.

Summary: This article reviews the pearls and pitfalls of toxic alcohol ingestion and its diagnosis and management in the emergency department, based on current evidence. Toxic alcohols include ethylene glycol, methanol, isopropyl alcohol, propylene glycol, and diethylene glycol. Timely diagnosis is crucial to prevent irreversible organ damage or death, and treatment depends on the ingestion and severity of illness.
