In this communication, we report the successful synthesis of gradient morphology nanoparticles composed of poly(styrene- <italic>co</italic> -methyl methacrylate) and their characterisation using X-Ray Photoelectron Spectroscopy (XPS).
Amorphous poly(vinyl phenol) (PVPh) is introduced into poly(butylene succinate-co-butylene adipate)/poly(l-lactic acid) (PBSA/PLLA) blends via solution casting. Fourier transform infrared spectroscopy (FTIR) analysis verifies that intermolecular hydrogen bonding formed in PBSA/PVPh/PLLA blends. The miscibility between…
Tissue adhesives, which inherently serve as wound sealants or as hemostatic agents, can be further augmented to acquire crucial functions as scaffolds, thereby accelerating wound healing or elevating the efficacy of tissue regeneration. Herein, multifunctional adherent fibrous matrices, acting as self-adhesive scaffol…
The voltage-tunable multicolor emission was realized in a poly(p-phenylene)/nanoporous ZnMnO organic-inorganic hybrid light-emitting diode. Red, green, and blue (RGB) colors sequentially appeared with increasing magnitude of the bias voltage (i.e., R → RG → RGB with V↑). At a higher voltage (>2.4 V), eventually, the d…
Eu2+ doped SrI2 is an important scintillator having applications in the field of radiation detection. Codoping techniques are often useful to improve the electronic response of such insulators. Using first-principles based approach, we report on the properties of SrI2:Eu and the influence of codoping with aliovalent (…
Hierarchical assembly of hard/soft nanoparticles holds great potential as reinforcements for polymer nanocomposites with tailored properties. Here, we present a facile strategy to integrate polystyrene-grafted carbon nanotubes (PSgCNT) (0.05-0.3 wt %) and poly(styrene-b-[isoprene-ran-epoxyisoprene]-b-styrene) block co…
Multicomponent nano-agents were designed and built via a core-shell approach to enhance their surface enhanced Raman scattering (SERS) signals. These nano-agents had 36 nm × 12 nm gold nanorod cores coated by 4 nm thick silver shell films and a subsequent thin bifunctional thiolated polyethylene glycol (HS-PEG-COOH) l…
Using the first-principles calculations, we have systematically investigated the atomic configurations, electronic structures, formation energies and transition energies of native point defects in cuprite Ag2O. Under the conditions of Ag-rich, we find that the oxygen vacancy (VO) and the oxygen interstitial (Oi) have…
-PEI@AuNSs-EGCG/PEG is a promising, potentially effective, theranostic nanoplatform for tumour treatment.
In the past decade, electro-assisted sol–gel deposition was employed by different groups in the world to deposit thin coatings on a variety of substrates. By applying a negative potential, the reduction reactions of water and oxygen occur at the working electrode, and the concurring generation of hydroxide makes the p…
A simple and scalable method, based on dip-coat colloidal lithography, mask reduction, and plasma-based pattern transfer, is presented to create graded-index, moth eye-inspired antireflective features on II–VI semiconductors. Hexagonal arrays of isolated conical frusta with tunable geometry (top diameter = 200–1300 nm…
In this study, a novel aggregation-induced emission (AIE) enhancement triggered by the self-assembly of chiral gelator is described. Tuning of molecular chirality in situ triggers different assemblies of superstructures exhibiting fluorescence. This novel AIE material can constitute an emerging library of chiral supra…
Dislocations in shock loaded tantalum single crystals were imaged using both transmission electron microscope (TEM) and electron channelling contrast image (ECCI) in a scanning electron microscope with a conventional backscattered electron detector. The results were compared with backscattered electron intensity profi…
Semiconductor heterostructures for solar energy conversion interface light-harvesting semiconductor nanoparticles with wide-band-gap semiconductors that serve as charge acceptors. In such heterostructures, the kinetics of charge separation depend on the thermodynamic driving force, which is dictated by energetic offse…
Abstract This paper reviews experimental phase diagrams of cuprates and pnictides to demonstrate that specific features of the superconducting phase diagrams in both HTSC families can be understood within the framework of the proposed approach, which assumes the formation, under heterovalent doping, of localized trion…
The novel coordinate compounds T 8 [(CH 2 ) n -EWG] 8 F – -18-crown-6-M + were prepared by reaction of EWG-(CH 2 ) n -Si(OEt) 3 (where n = 1–3 and the electron-withdrawing group, EWG, contains an Si–C(sp 3 ) bond) with an 18-crown-6-M + F – complex (where M + is K +, Cs +, and Rb + ) in the presence of a limited amoun…
meso-Tetraalkylporphycenes were synthesized in a few steps using intramolecular oxidative coupling of the Z-isomer of 5,6-dialkyldipyrroethenes. The use of a hypervalent iodine(III) reagent, namely phenyliodine(III) bis(trifluoroacetate), is essential for performing these reactions. A few step synthesis of meso-tetraa…
Tuning the microstructure, conductance, band gap of a single molecule with an external stimuli such as light have vital importance in nanoscale molecular electronics. Azobenzene systems are inimitable light responsive molecules suitable for the development of optically modulated materials. In this work we have demonst…
Thermal transformations of binary mixtures of hydrocarbons and fluorocarbons under high pressures demonstrate significantly lower initiation temperature thresholds for all major transformation stages, including carbonization, graphitization, and diamond formation, than the transformations of pure hydrocarbon and fluor…
This book deals with experimental results of the physical characterization of several important, dielectric materials of great current interest. The experimental tools used for the analysis of these materials include X-ray diffraction, dielectric measurements, magnetic measurements using a vibrating sample magnetomete…
