In this short review, we report on the recently found growing experimental evidence for the existence of Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) states in quasi-two-dimensional organic superconductors. At high magnetic fields aligned parallel to the conducting organic layers, we observe an upturn of the upper critical…
Well-defined thermosensitive poly[tri(ethylene glycol) monoethyl ether methacrylate] (P(TEGMA-EE)) brushes were synthesized on a solid substrate by the surface-initiated atom transfer radical polymerization of TEGMA-EE. The polymerization reaction was initiated by 2-bromo-2-methylpropionate groups immobilized on the s…
The effect of La 3+ and Nd 3+ on piezoelectric, dielectric and ferroelectric properties of PZT (Pb(Zr 0.53 Ti 0.47 )O 3 ) was studied. The powders were prepared by “wet-chemical” route followed by calcination at 800 °C for 4 h. XRD analysis of the calcined powders confirms the tetragonal phase in the undoped PZT, whic…
The aim of present study is to develop a toughened polylactic acid/talc composite. Talc and epoxidized natural rubber (ENR-50) were compounded with polylactic acid using counter-rotating twin-screw extruder followed by preparation of samples through injection molding. The effect of silane-treated talc and epoxidized n…
BACKGROUND: Sequential low-dose chemotherapy has received great attention for its unique advantages in attenuating multidrug resistance of tumor cells. Nevertheless, it runs the risk of producing new problems associated with the accelerated blood clearance phenomenon, especially with multiple injections of PEGylated l…
When imaging insulating specimens in a scanning electron microscope, negative charge accumulates locally ('sample charging'). The resulting electric fields distort signal amplitude, focus and image geometry, which can be avoided by coating the specimen with a conductive film prior to introducing it into the microscope…
This work reports the mechanical properties and corrosion performance of a newly fabricated series of protective epoxy coatings for offshore applications. Bisphenol A diglycidyl ether epoxy resin (DGEBA) was treated with different stoichiometry variations of polyamidoamine adducts (ARADUR-PA450) as a curing agent at a…
Recent years have seen a growing interest in using metal nanostructures to control temperature on the nanoscale. Under illumination at its plasmonic resonance, a metal nanoparticle features enhanced light absorption, turning it into an ideal nano‐source of heat, remotely controllable using light. Such a powerful and f…
The metal-reducing bacterium Shewanella oneidensis MR-1 has been employed to obtain Ag 2 S nanoparticles from an aqueous solution of AgNO 3 and Na 2 S 2 O 3 at an ordinary temperature and pressure. The nanoparticles vary in size within 2–16 nm, and the fraction 6 to 12 nm in size constitutes about 70%. The maximum yie…
We investigated the effect of surface temperature on deuterium retention in self-damaged tungsten exposed to high-flux deuterium plasmas. The retention saturates at a W 4+ fluence of about 3 × 10 17 m −2 and is strongly reduced for the present high surface temperatures of 800–1200 K as compared with previous experimen…
A novel manganese peroxidase (MnP) isolated from solid state culture of Trametes versicolor IBL-04 was immobilized using xerogel matrix composed of trimethoxysilane (TMOS) and propyltetramethoxysilane (PTMS). FTIR spectroscopy confirmed the successful entrapment of MnP into the xerogel matrix. An immobilization effici…
The field of nanoscience is expected to make significant contributions to contemporary medicine by providing unique solutions to critical problems. These solutions require the design of hybrid materials/systems with new properties and functionalities. This review focuses on spherical polymer nanocompartments (capsules…
The flat circular-shaped shells from Placenta placenta demonstrate high optical transparency in the visible light range while still maintaining mechanical robustness. The optical and mechanical design of this mineralized material system in correlation to its multiscale structural and crystallographical features are di…
In this work, an exhaustive study of the calculation of micropore and mesopore volumes with α s -plot method as proposed by Professor Sing is carried out. The method is critically compared with other similar methods such as the Dubinin–Radushkevich, t-plot and those based on density functional theory (DFT). For compar…
Zinc oxide nanoparticles (ZnO2), a common ingredient of cosmetics has a huge variety of applications. Previous studies reported oxidative stress mediated toxicity of ZnO2 nanoparticles on various mammalian cell lines. Although zinc (Zn) is an essential mineral at higher concentrations this metal is toxic. The present…
Melt spinning of polypropylene nonwoven nanofiber mats is demonstrated using Forcespinning. The effects of rotational speed and melt flow rate of polymer on fiber diameter were studied. It was observed that melt flow rate of the polymer plays a major role in nanofiber formation and uniformity. Differential scanning ca…
In recent years, nanoparticles (NPs) and related applications have become an intensive area of research, especially in the biotechnological and biomedical fields, with magnetic NPs being one of the promising tools for tumor treatment and as MRI-contrast enhancers. Several internalization and cytotoxicity studies have…
Microstructure stability is essential to maintain a fine grain structure for an alloy throughout its processing. The effects of Er addition and its existing form on the static recrystallization and grain growth during annealing of an extruded Mg–1.5Zn–0.6Zr magnesium alloy were studied in this paper. The results showe…
BiFe1-xCrxO3 (x = 0.0, 0.05 and 0.1) nanoparticles are prepared by the combustion method without using any solvent. All the synthesized nanoparticles are single phase in nature, nearly spherical in shape and crystallize in distorted perovskite structure (space group R3c) with an average crystallite size of the order o…
Till date several methods of chemical synthesis of silver nanoparticles (AgNps) are known. Most of the protocol dealing with the chemical synthesis of AgNps involves high pressure, temperature, energy and technical skills. Thus, a method with much greener approach is the need of the hour. Accordingly, the authors have…
