Abstract Conventional amine‐capped perovskite nanocrystals (A‐PNCs) often show microscopic fluctuation (blinking) of photoluminescence (PL) between bright and near‐background (dark) states. The transient dark phases spanning milliseconds (ms) to several seconds timescale typically owe the non‐radiative (NR) fate charge carriers in crystal defect states, limiting PNC's efficiency optoelectronics. A PL study a novel trioctylphosphine (TOP) capped rhombic cuboctahedron‐shaped amine‐free (AF)...
Kaolinite clay supported doped TiO<sub>2</sub> and anisotropic gold deposited visible light induced plasmonic nanocatalysts for dye degradation esterification reactions.
Leveraging ligand shell engineering, our study elucidates the structure and origin of luminescence in sulfur dots. These dots are consisting multiple aggregated species, where aggregation level governs their luminescent colors.
Single-molecule measurements are crucial for studying the interactions between G-quadruplex (GQ) DNA and ligands, as they provide higher resolution sensitivity compared to those of bulk measurements. In this study, we employed plasmon-enhanced fluorescence investigate real-time interaction cationic porphyrin ligand TmPyP4 different topologies telomeric GQ at single-molecule level. By analyzing time traces bursts, extracted dwell times ligand. For parallel DNA, distribution followed a...

Synthesis of highly active and recyclable nanocatalyst is important from the application perspective. This study reports a novel strategy for organization as synthesized Pd nanoparticles via green route using natural surfactant Acacia (Acacia auriculiformis) clove bud (Syzygium aromaticum) extracts into fractal patterns evaporating sessile drops on flat surfaces (glass silicon wafer). The studies based effects individual components used during synthesis process show that flavonoids present...
The present study deals with the preparation of new cellulosic catalyst materials, viz. paper and textile industry waste. Activated nano-carbons were prepared from these waste materials using thermo-chemical method. Nano-silver particles (AgNP) embedded into synthesized carbons to incorporate antimicrobial properties. characterized FESEM-EDX, XRD, FTIR, etc. characterization results showed that nanoporous silver was uniformly distributed throughout catalyst. suitability as an agent studied...
The Aegle marmelos leaf extract (LE) mediated synthesis of prismatic and spherical Ag nanoparticles (NPs) has been studied. formation structures from NPs was observed microscopically using scanning electron microscope, transmission atomic force microscope. shape transformation to nanostructures studied by simply changing LE concentration, keeping constant AgNO 3 concentration (1 mM). role pH toward prism the effect sonication on formed were also investigated. antimicrobial activity...
