Graphitic sulfur functionalized carbon sheets as an efficient “turn-off” absorption probe for the optical sensing of mercury ions in aqueous solutions

New Journal of Chemistry (2022)

Vishal Bharati Jaryal Dilbag Singh Neeraj Gupta

The sulfur - rich activated carbon (g-SFCSs) derived from coconut husk is used for detection of Hg 2+ ions. The presence of sulfur groups results in remarkable absorbance quenching of g-SFCSs on the addition of different concentrations of Hg 2+ ions.

Applications of ZnO Nanoflowers as Antimicrobial Agents for <I>Escherichia</I> <I>coli</I> and Enzyme-Free Glucose Sensor

Journal of Biomedical Nanotechnology (2013)

Ahmad Umar M.S. Chauhan Sachin Kumar Chauhan Ramesh Kumar Pankaj Sharma

Well-crystalline ZnO nanoflowers were prepared by a facile solution process and their applications as an antimicrobial agent against Escherichia coli and enzyme-free glucose sensor have been studied. The morphological, structural, compositional, and optical properties of ZnO nanoflowers were characterized by various techniques, which confirmed the well-crystalline wurtzite hexagonal phase. The minimum inhibitory concentration of ZnO nanoflowers for inhibiting the growth of Escherichia coli was found to be 25 microg/ml. ZnO nanoflowers were also tested as an efficient electron mediator for the fabrication of highly sensitive non-enzymatic glucose sensor, which exhibited a high sensitivity of -411 microA M(-1) cm(-2) and detection limit of -1.25 mM with a quick response time of -10.0 s. The presented studies showed that ZnO nanomaterials can be efficiently used as an antimicrobial agent and a highly sensitive non-enzymatic glucose sensor.

CHEMICAL SYNTHESIS AND VISIBLE PHOTOLUMINESCENCE EMISSION FROM MONODISPERSED ZNO NANOPARTICLES

Pathik Kumbhakar Dilbag Singh Chandra Sekhar Tiwary

Monodispersed PVP capped nanoparticles of ZnO have been prepared in double distilled water through chemical technique. Nanostructures of the prepared ZnO particles have been confirmed through XRD, TEM, and UV-VIS absorption characterizations. The average size of the prepared ZnO nanoparticles is as small as 1.9 nm. A strong green photoluminescence emission under UV excitation is reported from the prepared ZnO nanoparticles due to the recombination of a photo-generated hole with a singly ionized charge state.

Recent Developments in Heterogeneous Catalytic Routes for the Sustainable Production of Succinic Acid from Biomass Resources

ChemSusChem (2020)

Minal Verma Parteek Mandyal Dilbag Singh Neeraj Gupta

Succinic acid is a "hot molecule" identified by United States Department of Energy as a substitute for petrochemicals with great scope for its production from biomass. It is used as an intermediate for the production of a huge variety of everyday consumer products with an addressable market share of billions of dollars. Succinic acid and its derivatives are mainly used as pharmaceuticals, adhesives, solvents, intermediates for polymer synthesis, and food additives. Succinic acid is commercially produced from petrochemicals and there is a deficiency of economically viable catalytic processes for its large-scale production from biomass. Recently, a lot of biochemical routes have been devised to enhance its production from biomass resources, but such processes are time-consuming and involve tedious separation procedures. Therefore, this Review focuses on metal-based and metal-free heterogeneous catalytic routes for the synthesis of succinic acid from biomass derived products. The presence of uniform channels, cavities, active sites of various strengths, and the unique surface structure of the heterogeneous catalysts are a few of the interesting features that promote their use in industrial processes.

Online Learning

Advances in higher education and professional development book series (2024)

Amrik Singh Dilbag Singh Sumit Chhikara

The coronavirus (COVID-19) was declared a global pandemic on 12 March 2020 and social distancing was adopted in many places to contain the problem. Indeed, numerous countries around the world decided to close educational institutions nationwide to prevent or contain the spread of the virus, significantly affecting the learning of millions of students in higher education institutions. COVID-19 has highlighted the problem of the management of classroom teaching and learning processes worldwide. Online learning, which involves interactions that are mediated through using digital, typically internet-based, technology, is pervasive, multi-faceted, and evolving, creating opportunities and challenges for educational research in the wake of the COVID-19 pandemic. The present study aims to investigate the challenges of online learning and suggestions to improve student engagement through the intersection of educational technology, and online platforms that stimulate the learning sciences in higher education institutions.
