A cosurfactant-mediated microemulsion synthesis of free-standing CuO arrays with hierarchical micro-cog architectures on copper substrates has been successfully established. The CuO cog-array films directly employed as anode electrodes derive from thermal dehydration of Cu(OH)2 arrays grown from copper substrates in t…
The surface plasmon resonance evaluation of colloidal metal nanoparticles, synthesized in organic medium, is reported in this work. Metal salts were dissolved in dioxane/AOT solution and reduced by hydrazine hydrate under vigorous stirring. Optical properties of obtained colloidal nanoparticles were investigated by UV…
The reversible addition and fragmentation (RAFT) polymerization of vinyl pyrrolidone (VP) from graphene oxide (GO) is used to produce GO-g-PVP (GP) and the grafting is confirmed from Fourier transformed infrared (FTIR) and nuclear magnetic resonance spectra. The average thickness of GP (8.2 nm) obtained from atomic fo…
Investigation into the use of artificial enzymes has become an increasingly popular area of research due to the numerous advantages offered in comparison to protein enzymes. One particular area of research interest involves the use of metal nanoparticles as artificial enzymes. The peroxidase-like activity of a variety…
The subjects of the symposia are on composite materials behaving as brittle, normal and special conditions of exploitation. Brittle matrix composites are applied in various domains and the series of symposia are closely related to their applications in civil engineering. In the last decades their importance is increas…
ZnS nanoparticles are prepared by coprecipitation method using various capping agents like PVP (polyvinylpyrrolidone), PVA (polyvinylalcohol) and . These are characterized by UV-Visible spectra, X-ray diffraction (XRD) studies, Fourier Transform Infra-red spectra (FTIR) and Transmission electron microscopy (TEM). UV-V…
Due to its biodegradability, biocompatibility, weak antigenicity and well-known safety profile, collagen becomes a very useful carrier for the delivery of various kinds of drugs and agents like growth factors, collagen possess some very unique properties as compare to other drug carriers that’s why a numerous number o…
A novel and very simple photochemical strategy that utilizes light as a facile means to provide spatio-temporal control for the direct covalent immobilization of nucleophiles is presented. The concept is based upon the efficient trapping of photogenerated thioaldehydes by amines, hydroxylamines, and thiols. Surface pa…
Faster nucleation of hydroxyapatite (HAP) at lower pH (with lower supersaturation) contradicts classical understanding. We find that the residue calcium ion in the mother liquor is the key to trigger ACP phase transformation, which gives an understanding of nonclassical nucleation kinetics of ACP-mediated crystallizat…
We describe the synthesis of self-assembling cyclic octapeptides of alternating D- and L-chirality conjugated to two poly(2-ethyl-2-oxazoline) chains. The resulting conjugates form nanotubes in water, which are reversibly transformed into microparticles as the temperature reaches the cloud point temperature of the con…
We report a thorough experimental study on the microstructure, thermal behavior and thermoelectric properties of the amorphous composition Cu15As30Te55 and the glass–ceramics related-compounds synthesized by using the Spark Plasma Sintering (SPS) technique. Varying the conditions of the SPS process enables the synthes…
We report the pH and ionic strength triggered self-assembly of polyanionic dendritic peptide amphiphiles into well-defined nanorods in water; by establishing state diagrams we show how frustrated growth is used as a sensitive tool in order to manipulate and control the one-dimensional supramolecular polymerisation pro…
In this article we have demonstrated the influence of growth-temperature on the morphology and orientation of SnS films deposited by thermal evaporation technique. While increasing the growth-temperature, the morphology of SnS films changed from flakes-like nanocrystals to regular cubes, whereas their orientation shif…
In this article, we have investigated spin polarized electronic transport in two dimensional sheet materials of silicon and germanium, such as, monolayer silicene and germanene, using semi-classical Monte-Carlo approach. Monte-Carlo simulations are used to model spin transport along with spin density matrix calculatio…
It is well documented that dendrimers were described as one of the most tunable nanomaterials both for therapeutic applications and diagnostics. This concise review surveys the different types of both non-targeted and targeted drug-encapsulated dendrimers and dendrimer–drug conjugates in oncology. In addition, progres…
We present a series of hydrogel nanoparticles (nanogels) incorporating either acyclic or cyclic gadolinium chelates as crosslinkers. These crosslinkers are used to formulate polyacrylamide-based nanogels (diameter 50 to 85 nm) yielding contrast agents with enhanced relaxivities (up to 6-fold greater than Dotarem®), be…
A new two-dimensional cobalt based phthalocyanine covalent organic framework (CoPc-BPDA COF) has been synthesized under solvothermal conditions. CoPc-BPDA COF exhibits a high surface area (SBET = 1087 m2 g−1), and it can store up to 1.2 wt% of hydrogen at 77 K and 1 bar.
We report a facile fabrication method for the fabrication of functional large area nanostructured polymer films using a drop casting technique. Reusable and tapered silicon molds were utilized in the production of functional polymers providing rapid fabrication of the paraboloid nanostructures at the desired structura…
Self-assembled peptide materials have received considerable interest for a range of applications, including 3D cell culture, tissue engineering, and the delivery of cells and drugs. One challenge in applying such materials within these areas has been the extreme stability of β-sheet fibrillized peptides, which are res…
Calcium and strontium metals react with Hg(C6F5)2 and 2,4-di-tert-butylphenol (H-DBP) in tetrahydrofuran (THF) and 1,2-dimethoxyethane (DME) to give [Ca(DBP)2(THF)4] (1), [Ca2(DBP)4(DME)4(μ-DME)] (2), [Sr3(μ-DBP)6(THF)6] (3), and [Sr2(DBP)(μ-DBP)3(DME)3] (4). Compound 1 is a six coordinate trans-octahedral monomer, wh…
