In-field deployable and facile nanosensor for the detection of pesticides residues.

Local air and water should be first priority to understand the environment of any area. Different categories of contaminants behave like bottleneck situation in collection and analysis of data about abiotic factors for the understanding and resolving the environmental issues. In digital age the emerging nano technology enroll its role to meet the needs of hour.

High performance and gate-controlled GeSe/HfS negative differential resistance device.

Transition metal dichalcogenides (TMDs) have received significant attention owing to their thickness-dependent folded current-voltage ( - ) characteristics, which offer various threshold voltage values. Owing to these astonishing characteristics, TMDs based negative differential resistance (NDR) devices are preferred for the realization of multi-valued logic applications. In this study, an innovative and ground-breaking germanium selenide/hafnium disulfide (p-GeSe/n-HfS) TMDs van der Waals heterostructure (vdWH) NDR device is designed.

Construction of 1T-MoS quantum dots-interspersed (Bi Fe )VO heterostructures for electron transport and photocatalytic properties.

The present study reports trigonal phase molybdenum disulfide quantum dots (MoS/QDs)-decorated (Bi Fe )VO composite heterostructures. Initially, (Bi Fe )VO heterostructure nanophotocatalysts were synthesized through the hydrothermal method decorated with 1T-MoS a sonication process. 1T-MoS@(Bi Fe )VO heterostructures were characterized in detail for phase purity and crystallinity using XRD and Raman spectroscopy.

Bismuth vanadate/MXene (BiVO/TiC) heterojunction composite: enhanced interfacial control charge transfer for highly efficient visible light photocatalytic activity.

We have synthesized BiVO/TiC nanocomposite via a low-cost hydrothermal method and investigate its photocatalytic degradation activity against monoazo (methyl orange) and diazo dye (Congo red) in an aqueous solution under visible light. The physiochemical characterization exhibited that the addition of MXene in pristine BiVO nanocomposite led to an increase in specific surface area and reduction in optical band gap energy. MXene also helps in enhancing visible light response via a higher electron-hole pair generation rate and long lifetime.

Biotransformation and toxicity evaluation of functionalized manganese doped iron oxide nanoparticles.

Safe inorganic nanomaterials are tremendously used for diagnosis and therapies. However, essential processing in the microbiological environment changed the physical properties and in situ degradability, which is evaluated meticulously. In this research article, bare, Polyethylene glycol, and citrate coated manganese doped iron oxide nanoparticles are synthesized through the coprecipitation route.

Solution growth of 1D zinc tungstate (ZnWO) nanowires; design, morphology, and electrochemical sensor fabrication for selective detection of chloramphenicol.

Development of 1D nanostructures with novel morphology is a recent scientific attraction, so to say yielding unusual materials for advanced applications. In this work, we have prepared solution grown, single-pot 1D ZnWO nanowires (NWs) and the morphology is assessed for label-free but selective detection of chloramphenicol. This is the first report where, such structures are being investigated for this purpose.

Synthesis of Zn(VO)/BiVO heterojunction composite for the photocatalytic degradation of methylene blue organic dye and electrochemical detection of HO.

In this study, a Zn(VO)/BiVO heterojunction nanocomposite photocatalyst was prepared using a hydrothermal route with different molar concentration ratios. The as-synthesized nanophotocatalyst was characterized using XRD, SEM, EDS, XPS, FT-IR, Raman, BET, UV-vis DRS, EPR and PL. The effect of molar ratio on composition and morphology was studied.

Visible light assisted photocatalytic degradation of crystal violet dye and electrochemical detection of ascorbic acid using a BiVO/FeVO heterojunction composite.

A BiVO/FeVO nanocomposite photocatalyst was successfully synthesized a hydrothermal method. The prepared heterojunction photocatalyst was characterized physically and chemically using XRD, SEM, EDX, XPS, BET, FT-IR, Raman, UV-vis DRS, EPR and photoluminescence techniques. BiVO/FeVO was explored for its photocatalytic activity by the decomposition of crystal violet (CV) organic dye under visible radiation.
