Rapid Thermal Processing (RTP) technology was employed to perform flash grafting reactions of a hydroxyl terminated poly(styrene- <italic>r</italic> -methylmethacrylate) random copolymer to a silicon surface.
Triple core-shell structures in the Cu24Gd6 and Cu24Dy6 clusters were first observed and structurally characterized. The magnetic investigations reveal that Cu24Gd6 possesses the significant magnetic entropy change (-ΔSm) of 21.2 J kg(-1) K(-1) for ΔH = 7 T, and a slow magnetization relaxation is observed in Cu24Dy6.
We present a significant efficiency enhancement of hybrid bulk heterojunction solar cells by utilizing CdSe quantum dots attached to reduced graphene oxide (rGO) as the electron accepting phase, blended with the PCPDTBT polymer. The quantum dot attachment to rGO was achieved following a self-assembly approach, recentl…
The light-induced <italic>trans</italic> -to- <italic>cis</italic> -isomerization of a single azobenzene moiety triggers the disintegration of a dimeric tetraurea calix[4]pyrrole capsule.
The hydrogen sorption properties of oxide-supported Ir-Pd nanoalloys have been determined for the first time, and correlated with their catalytic behavior. The addition of Ir to Pd suppresses hydride formation and leads to improved catalytic performances with respect to pure metals in the preferential oxidation of CO…
In this work, we report a novel and feasible strategy for the practical applications of one-dimensional ultrasensitive phototransistors made of tungsten-doped VO2 single nanowires. The photoconductive response of the single nanowire device was investigated under different visible light excitations (405 nm, 532 nm, and…
Graphene oxide membranes were recently suggested for applications in separation of ethanol from water using a vapor permeation method. Using isotope contrast, neutron reflectivity was applied to evaluate the amounts of solvents intercalated into a membrane from pure and binary vapors and to evaluate the selectivity of…
We report a new type of fast photochromic imidazole dimer, pentaarylbiimidazole (PABI), which shows a few μs fast photochromism with high fatigue resistance against light irradiation. PABI has an unusual spiroconjugated imidazoisoindole skeleton and its derivatives can be prepared by simple synthetic procedures.
complex, in medical biotechnology. The fabrication of such self-assembled idiosyncratic capsules is very simple, feasible, and cost effective; moreover, it demonstrates improved performance in drug and gene delivery applications.
Monodisperse Pr(3+)/Yb(3+):NaGdF₄@NaYF₄ active-core/inert-shell nanoparticles, which exhibit efficient near-infrared quantum-cutting luminescence, are successfully prepared. In order to relieve the adverse effect caused by concentration quenching in the core, the extra Yb(3+) ions are introduced into the shell, formin…
Nanocrystalline form of manganese ferrite (MnFe2O4) has been synthesized by simple sol-gel auto combustion method using citric acid as chelating agent. The obtained nanocrystalline powders of manganese ferrite were subjected to structural and magnetic measurements. Temperature dependent magnetization was also carried…
Magnesium alloys are lightweight materials primarily used in transportation industry, and are also emerging as a potential material for biodegradable fixation implants. However, unsatisfactory corrosion resistance largely limits the application of these materials. Residual stresses were reported to have significant in…
Silver sulfadiazine (AgSD) is the leading topical antibacterial agent for the treatment of burn wound infections. Antibacterial effect of AgSD is limited by its poor aqueous solubility, and antibacterial activity develops only by decomposition of AgSD to silver ions and sulfadiazine. In this study, it is for the first…
The adsorption of a series of aromatic compounds from aqueous solution onto purified, free-standing single-walled carbon nanotube/graphene nanoplatelet hybrid papers is studied both experimentally and theoretically. Experimental data is obtained via changes in optical absorption spectra of the aqueous solutions and is…
A chemical reduction-based, morphology-controlled synthesis of K-containing manganese oxide nanostructures for electrochemical supercapacitor application.
The eect of particle size on the magnetic and optical properties of cobalt oxide Co3O4 has been investigated. Single phase Co3O4 nanoparticles were synthesized by co-precipitation route and their structure was conrmed through X-ray diraction analysis. The average crystallite sizes of the nanoparticles as determined fr…
Silica nanotubes with controlled diameters and lengths were fabricated by a template-directed method. Nanowires composed of poly(2-dimethylaminoethyl methacrylate)-block-polystyrene (PDMAEMA–PS), which were fabricated by RAFT dispersion polymerization of styrene in methanol using PDMAEMA as a macro-RAFT agent, were us…
A thorough characterization of thermally obtained Cu( <sc>i</sc> )/Cu( <sc>ii</sc> ) oxide (photo)electrodes has been conducted for applications of solar fuel generation.
Single phase nanoparticles (NPs) of CeO2, Ce0.5Zr0.5O2, Ce0.5Hf0.5O2 and Ce0.5Hf0.25Zr0.25O2 were successfully synthesized by co-precipitation method at constant pH and temperature. The X-ray diffraction results revealed that the additive atoms did not segregate to form secondary phases but led to grain size variation…
Linear and hyperbranched poly(azomethine)s (PAMs)-based on triphenylamine moieties are synthesized and used as the functioning layers in the Ta/PAM/Pt resistive switching memory devices. Comparably, the hyperbranched PAM with isotropic architecture and semi-crystalline nature shows enhanced memory behaviors with more…
