Dielectric spectra of two K0.5Na0.5NbO3 ceramics with different grain sizes (10 and 0.5 μm) were measured from 102 to 1014 Hz in a broad temperature range. The sequence of first-order phase transitions (cubic-tetragonal-orthorhombic-rhombohedral) was detected by differential scanning calorimetry, dielectric spectrosco…
Textiles are ubiquitous materials that many of us take for granted in our everyday lives. We rely on our clothes to protect us from the environment, for modesty, to enhance our appearance and reflect our personality. Beyond these traditional applications, high-performance fibres have been specifically developed for mo…
A simple method of fabricating pristine few-layer and single-layer graphene which could be used for production on a gram scale is described.
In this article it is demonstrated how the combination of a novel gas-in-liquid-templating method followed by foam freezing in liquid nitrogen can be exploited for the synthesis of polysaccharide based porous materials endowed with characteristics particularly suited for tissue engineering applications. The model poly…
Chiral-mesoporous-polypyrrole (CMPPy) nanoparticles are synthesized by templating chiral block copolymers (CBCs) of poly(ethylene oxide), (PEO) and chiral L-/D- glutamic acid [PEO-b-(L-/D-GluA)10] and blocks of chiral L-/D-phenylalanine [PEO-b-(L-/D-Phe)10]. The well ordered chiral mesopores of nanoparticles are chara…
The performance and durability for Ni-YSZ and Ni-ScSZ anodes of solid oxide fuel cells were compared between internal steam and reforming of methane in the carbon deposition conditions. With a supply of mixtures to the anode, the polarization resistance increased with a rise in CO concentrations at 1023 K because of t…
Noble metal nanocrystals with controlled morphologies play important role in many fields, such as catalysis and SERS, etc. To date, solution-based methods developed to synthesize nanocrystals mainly exploit organic reagents as solvents including polyol, oleic acid/oleylamine, toluene, diphenyl ether and so on. In orga…
In as-cast structure of AISI M2 steel, the predominant type of eutectic carbides is M2C, the morphology of which has crucial influence on the distribution and dimension of carbides in final products. In the present work, the morphology and properties of M2C carbides formed at different cooling conditions have been inv…
Reactant incompatibility is a common problem in organic chemistry. This study investigates the use of concentrated aqueous dispersions of mesoporous oxides to overcome incompatibility. Oxidation of cyclohexene into adipic acid using aqueous hydrogen peroxide as oxidant has been performed in a range of ordered and diso…
Simple oil-in-water emulsion led to structural complexity at both the surface and interior of the PLGA microsphere. A golf ball-like dimpled surface comes from the heteroaggregation of volatile nonsolvent colloid originating from the inside of the organic droplet as supported by in situ optical microscopy. The interna…
The dissimilar metal weld is demanding as well as the similar weld, however, dissimilar weld is more complex than similar weld due to the necessity of being applied in zones where a requirement is to improve some properties. In this work the main purpose is to know the mechanical behavior of a dissimilar weld between…
Clean fabrication of a five-component supramolecular triangle was elaborated via self-sorting. The robustness of the dynamic triangle against external stimuli was challenged by varying both the metal ions and their ratios. Self-sorting of five components proved to be superior to that of four components.
Soft polyester elastomers have emerged as a promising family of biodegradable materials for drug delivery and tissue engineering. Specifically referring to soft tissue engineering, potential biomaterials should be elastic and flexible, so as to mimic the mechanical properties of natural tissue. Herein, we report the d…
The synthesis and the photophysical studies of the first bodipy-DOTA and its In(III), Ga(III) and Cu(II) complexes are reported. The introduction of an isothiocyanate handle generates a new bimodal imaging agent capable of both optical and nuclear imaging.
A new series of distyryl-BODIPY has been rationally designed and synthesised from a novel fluorinated platform, 8-pentafluorophenylBODIPY, which has enhanced reactivity in the presence of both electron rich, and for the first time, electron deficient aldehydes. The pentafluorobenzene leads to larger red shifts of abso…
Hybrid semiconductors of the general formula 2D-[Cd2Se2(ba):Te] (ba = bultylamine) emit direct white light upon illumination of UV-LED. The band gap and photoluminescence properties of this group of materials can be systematically tuned by changing the composition and doping level. The sample with 25 mol% of Te corres…
Alkyl substituted 4-cyanoresorcinol 1,3-bisbenzoates with terephthalate based rod-like wings show a series of three orthogonal smectic phases SmA-SmAP(R)-SmAP(A).
FT-Raman, IR and UV-vis spectroscopies have been applied to investigate the potential nonlinear optical (NLO) material 4-methoxy-2-nitroaniline. A detailed interpretation of the vibrational spectra was carried out with the aid of normal coordinate analysis following the scaled quantum mechanical force field methodolog…
This paper summarizes topics on microorganisms able to degrade polylactic acid (PLA) and PLA depolymerases. Although the glass transition temperature for PLA is high (approximately 60 °C), PLA-degrading microbes can degrade solid PLA at far lower temperatures such as 30 or 37 °C. Such degraders are Actinomycetes belon…
Here we report for the first time, to the best of our knowledge, the synthesis of silver nanoparticles of varying sizes using parthenium leaf extract at a higher temperature of 100°C as well as at room temperature. The synthesized nanoparticles are characterized using Scanning electron microscope (SEM), X-ray diffract…
