Electrocatalytic efficiency of carbon nitride supported gold nanoparticle based sensor for iodide and cysteine detection.

Extensive investigations are being conducted on gold nanoparticles focusing on their applications in biosensors, laser phototherapy, targeted drug delivery and bioimaging utilizing advanced detection techniques. In this work, an electrochemical sensor was developed based on graphite carbon nitride supported gold nanoparticles. Carbon nitride supported gold nanoparticles (Au-CN) was synthesized by applying a deposition-precipitation route followed by a chemical reduction technique.

Electrical response of organic molecule supported preformed and formed antimony sulfide nanoparticles under frequency conditions.

A complexation route mediated synthesis of orthorhombic antimony sulfide nanoparticles is described in this report where uniformly distributed particles within the size range of 2-12 nm are stabilized within the aniline matrix. The organic-inorganic hybrid system was investigated for dielectric capacitance and electric field-induced polarization performances under varying temperature and frequency conditions. The AC-conductivity revealed a correlated barrier hopping conduction mechanism in the hybrid system.

Copper-azide nanoparticle: a 'catalyst-cum-reagent' for the designing of 5-alkynyl 1,4-disubstituted triazoles.

A single pot, wet chemical route has been applied for the synthesis of polymer supported copper azide, CuN, nanoparticles (CANP). The hybrid system was used as 'catalyst-cum-reagent' for the azide-alkyne cyclo-addition reaction to construct triazole molecules using substituted benzyl bromide and terminal alkyne. The electron donating group containing terminal alkyne produced 5-alkynyl 1,4-disubstituded triazole product whereas for alkyne molecule with terminal electron withdrawing group facilitate the formation of 1,4-disubstituted triazole molecule.

Enhancement of dielectric and electric-field-induced polarization of bismuth fluoride nanoparticles within the layered structure of carbon nitride.

A single-pot, wet chemical method has been reported for the synthesis of bismuth fluoride nanoparticles (BF) and functionalized BF within the network of carbon nitride (BFCN). In BFCN, a structural transformation of BF, from cubic to pseudo-cubic (as evidenced by Rietveld refinement analysis), confirmed the contribution of carbon nitride (CN) on functionalization. The effect of functionalization of BF has been investigated through dielectric and field-induced polarization studies under different temperature and frequency conditions.

Resistive switching characteristics of carbon nitride supported manganese oxysulfide: an evidence for the sweep dependent transformation of polarity.

As part of a program to investigate the materials for resistive random access memory (ReRam) applications, a study has been conducted using embedded manganese oxysulfide (MOS) nanoparticles on the thin film of carbon nitride (CN). A high-temperature in-situ route was employed to synthesis CN-MOS composite where thiourea and manganese chloride was used as the precursor. The electrical property of the CN-MOS composite system (active layer), sandwiched between two gold electrodes, was measured under different sweeping (voltage) conditions.

Organic-Inorganic Complexation Chemistry-Mediated Synthesis of Bismuth-Manganese Bimetallic Oxide for Energy Storage Application.

An organic-inorganic complexation method was applied for the synthesis of bismuth-manganese bimetallic oxide (BMO) nanoparticles where highly dispersed oxide particles were stabilized in an organic matrix (hexamethylenediamine). The as-synthesized hybrid material was subjected to microscopic, optical, and structural studies to gain comprehensive insights into the system. In the X-ray diffraction pattern, the majority of the diffracted peaks are matched to the orthorhombic phase of the BiMnO structure.

Organic molecule stabilized bismuth iodide nanoparticles: a hybrid system with multifunctional physical properties.

An organic-inorganic hybrid system of aniline stabilized bismuth iodide nanoparticles (ABI) was synthesized and investigated for its dielectric properties, AC-conductivity, polarization hysteresis and non-volatile memory performances. The X-ray diffraction result indicates the single phase crystalline nature of the nanoparticles and a microscopic image shows the homogeneous distribution of the bismuth iodide nanoparticles within the organic matrix. The material has exhibited a moderate dielectric performance via an interfacial polarization mechanism.
