In the current era, an ever-emerging threat of multidrug-resistant (MDR) pathogens pose serious health challenges to mankind. Researchers are uninterruptedly putting their efforts to design and develop alternative, innovative strategies to tackle the antibiotic resistance displayed by varied pathogens. Among several naturally derived and chemically synthesized compounds, quinones have achieved a distinct position to defeat microbial pathogens. This review unleashes the structural diversity and p...

The zinc oxide (ZnO) nanostructures were synthesized using hydrothermal reaction technique at 180 °C with varying reaction time viz., 2, 4, 8 and 12 h and characterized with different spectroscopic/microscopic techniques. XRD indicate the formation of hexagonal phase of ZnO in all the prepared samples. The FESEM confirms the formation of hexagonal-shaped plate-like ZnO nanostructures having size in the range of 50 to 100 nm with the thickness of 10–15 nm, at 2 h reaction time. Further increase i...

Green synthesis of nanoparticles has attracted significant attention as an alternative to chemical synthesis procedure. The bulk availability of plants, microbial biomass and the use of eco-friendly solvents has significantly reduced the cost in addition to the hazards associated with the chemical synthesis of the nanoparticle. In this study, we demonstrated the biosynthesis of titanium nanoparticles (TiO2NPs) with the extract of Trichoderma citrinoviridae as a reducing agent. The physicochemica...

We report a versatile epoxide assisted synthesis route of developing Ni/SnO2 xerogels and their use as efficient H2S gas sensors. Instead of expensive, non-aqueous and complicated organometallic precursors, epoxide route utilizes easy to handle salts as precursors (tin and nickel nitrates, in the present case) and epoxide (propylene oxide, in the present case) as a gelation agent. The obtained Ni/SnO2 xerogels with 1–4 mol% Ni doping, were analyzed using various physico-chemical techniques such ...

Abstract In recent times carbon black is getting part replaced in the tire industry by silica as the major reinforcing filler for the development of “greener tires”. The green claim comes from the fact that silica reinforcement helps in further fuel saving in vehicles and reduction in CO2 emission into the environment. Making the green claim further, researchers are also looking at reinforcement fillers that are synthesized from bio-waste as raw materials. In this paper we have evaluated the eff...

Traditionally, sol–gel processing of metal oxides using organometallic precursors is expensive, nonaqueous, and complicated when it comes to two-or-more dissimilar metal oxides. Herein, we report a versatile epoxide-assisted non-organometallic, aqueous, and inexpensive synthesis route of developing Cu/SnO2 xerogels and their use as efficient formaldehyde (FA) gas sensors. The route utilizes easy to handle salts as precursors (tin and copper chlorides, in the present case) and organic epoxide (pr...

Abstract Phellinus badius is one of the medicinal mushrooms used as folk medicine in Western Ghats of India. Traditionally, the P. badius is used in the treatment of diabetes, diarrhea, arthritis, toothaches, as well as tongue and throat related ailments. Therefore, we investigated the hypoglycemic and anticataract activity of P. badius crude exopolysaccharides (EPS) in streptozotocin (STZ) induced diabetic rats and Goat eye lens, respectively. The EPS obtained from the submerged mycelial cultur...

Abstract The cascade synthesis of 3-aroylimidazo[1,2-a]pyridines using chalcones and 2-aminopyridine was achieved over the SnO2/I2 catalytic system in toluene at ambient air atmosphere. The catalyst shows high activity towards the broad substrate scope of the various aromatic and heterocyclic chalcones with 2-aminopyridine, 4-methyl 2-aminopyridine, and 5-methyl 2-aminopyridine in good yields during the synthesis of 3-aroylimidazo[1,2-a]pyridines. The methodology was further extended for the one...

Abstract A robust synthesis approach to Al/SnO2 based formaldehyde gas sensing xerogels using epoxide assisted sol-gel chemistry is reported. The route utilizes simple tin and aluminum salt precursors in alcohol/water mixture, thus eliminating the need for organometallic precursors. Propylene oxide acts as a proton scavenger and drives metal hydroxide formation and subsequent polycondensation reactions. Al/SnO2 xerogels (with Al doping 1-4 mol%) were aged for 24h to strengthen the gel network, f...
