We report the systematic appearance of a plasmon-like optical absorption feature in silver clusters protected with 2-phenylethanethiol (PET), 4-flurothiophenol (4-FTP) and (4-(t-butyl)benzenethiol (BBS) as a function of cluster size. A wide range of clusters, namely, Ag₄₄(4-FTP)₃₀, Ag₅₅(PET)₃₁, ∼Ag₇₅(PET)₄₀, ∼Ag₁₁₄(PE…
We report the selective synthesis of CuGaS <sub>2</sub> nanostructures of different sizes (3.0–10.9 nm), phases (chalcopyrite and wurtzite) and morphologies (nanocrystals and nanowires) in hot-solvent synthesis.
We report here the first studies addressing fate and transport of single walled carbon nanotubes (SWNTs) in aquatic mesocosms.
. These Ag nanoplate arrays are used for SERS-based analysis of DNA hybridization monitoring, protein detection, and virus differentiation without any additional surface modifications or labelling. They all exhibit an extremely high detection sensitivity, reliability, and reproducibility.
Micropore engineering of porous carbons on the effect of capacitance was explored using a carbonized porous aromatic framework (PAF-1). The porous carbons obtained through different carbonization methods show different pore structures enabling us to do this. The capacitance was measured both in aqueous electrolyte and…
We show in the case of N,N'-dimethyl-N,N'-dioctyl-2-(2(hexyloxy)ethyl)-malonamide (DMDOHEMA) chosen as a typical oil-soluble extractant with surface activity that the free energy of formation of reverse micelles in the solvent phase strongly depends on the presence of polar solutes. Free energies per molecule vary typ…
Waste thermal energy, such as that released from industrial or manufacturing processes, is a promising but as-yet underutilized source of sustainable energy. As an alternative to traditional semi-conductor based thermoelectrics, thermoelectrochemical cells use a redox couple in an electrolyte to directly convert therm…
The efficacy of two nanocarriers polyethylene glycol and polyvinyl alcohol magnetic nanoparticles coated with gallic acid (GA) was accomplished via X-ray diffraction, infrared spectroscopy, magnetic measurements, thermal analysis, and TEM. X-ray diffraction and TEM results showed that Fe3O4 nanoparticles were pure iro…
AIM OF THE STUDY: The synthesis, characterization and application of biologically synthesized nanomaterials are an important aspect in nanotechnology. MATERIALS AND METHODS: The present study deals with the synthesis of silver nanoparticles (Ag-NPs) using the coconut water (C. nucifera) as the reducing agent. The form…
Carboxyl-terminated polymers are known as good candidates for realizing the surfaces pH-responsive wettability. In the present work, we have successfully fabricated smart fabrics with both pH-responsive water wettability in air and pH-responsive oil wettability underwater via in situ growth of Ag nanocrystals on the f…
We report on a supramolecular self-assembly system that displays coupled light switching, biocatalytic condensation/hydrolysis and gelation. The equilibrium state of this system can be regulated by light, favouring in situ formation, by protease catalysed peptide synthesis, of self-assembling trans- in ambient light;…
A solvothermal approach and a mutual oxidation–reduction strategy were demonstrated for the synthesis of RuO <sub>2</sub> -based nanocomposites for supercapacitors.
It has been stated clearly that nanofillers could make an enhancement on the mechanical performances of dental composites. In order to address current shortage of traditional dental composites, fillers in forms of nanofibers or nanotubes are broadly regarded as ideal candidates to greatly increase mechanical performan…

We report a facile, nanocasting synthetic method that results in nitrogen-doped mesoporous carbons with tailorable density of N-dopant and high charge storage capacity.
Herein, we report a simple, facile, green and cost effective strategy for the synthesis of graphene using naturally available anti-oxidants such as carotenoids present in vegetable (carrot, sweet potato, <italic>etc.</italic> ) extracts.
The Mg/Al-layered double hydroxides and iron oxide (LDHs–Fe3O4) nanocomposites were synthesized via a facile two-step wet chemistry route. The fabricated samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), high-resolution…

Blood-brain barrier (BBB) damage during ischemia may induce devastating consequences like cerebral edema and hemorrhagic transformation. This study presents a novel strategy for dynamically imaging of BBB damage with PEGylated supermagnetic iron oxide nanoparticles (SPIONs) as contrast agents. The employment of SPIONs…
Here we have designed a strategy to improve the electronic conductivities of polyoxometalates (POMs) via property-oriented organic grafting for use in lithium-ion batteries (LIBs). POMs usually exhibit limited electronic conductivity that hinders their use in electronic applications. Organic grafting of POMs defines a…
