The spin-phonon coupling in magnetic materials is due to the modulation of the exchange integral by lattice vibrations. BaFe12O19 M-type hexaferrite, which is the most used magnetic material as permanent magnet, transforms into ferrimagnet at high temperatures, but no spin-phonon coupling was previously observed at th…
The problem of conduction electron scattering by inhomogeneous crystal lattice strains is addressed using a tight-binding formalism and the differential geometric treatment of deformations in solids. In this approach, the relative positions of neighboring atoms in a strained lattice are naturally taken into account, e…
In this paper Al doped ZnO (AZO) thin films with 0, 3, 6 and 12 at. % Al concentration were prepared by sol-gel method on glass substrates. The deposited films were annealed at different temperatures of 300, 350, 400, 450 and 500 °C for 1 h in air. X-ray diffraction (XRD) showed wurtzite crystalline structure for the…
A practical and feasible bottom‐up chemistry approach is demonstrated to dramatically enhance thermoelectric properties of the Bi 2 Te 3 matrix by means of exotically introducing silver nanoparticles (AgNPs) for constructing thermoelectric composites with the hierarchical two‐phased heterostructure. By regulating the…
Novel ultrathin dual-functional metalenses are proposed, fabricated, tested, and verified in the microwave regime for the first time. The significance is that their anomalous transmission efficiency almost reaches the theoretical limit of 25%, showing a remarkable improvement compared with earlier ultrathin metasurfac…
Journal of Pharmaceutical Research International (ISSN: 2456-9119) is dedicated to publish high quality papers in all areas of pharmaceutical Science including pharmaceutical drugs, community pharmacy, hospital pharmacy, clinical pharmacy, compounding pharmacy, consultant pharmacy, internet pharmacy, veterinary pharma…
We investigated the surface-initiated atom transfer radical polymerization (SI-ATRP) of methyl methacrylate (MMA) using monodisperse rod-type particles of iron oxide, β-FeOOH. The slow hydrolysis of iron(III) chloride yielded monodisperse β-FeOOH rods with an average length-to-width ratio, L/W, of 6 (L = 210 nm and W…
Chiral, multipetal gold nanoflowers ( AuNFs ) with crystalline tips were synthesized in high yield through the reduction of HAuCl 4 in water in the presence of preformed core–satellite Ag nanoparticle ( AgNP ) seeds. High-resolution transmission electron microscopic (HRTEM) images and tomography reveal the actual crys…
Haemophilus influenzae, a Gram-negative bacterium and a member of the family Pasteurellaceae, causes chronic bronchitis, bacteremia, meningitis, etc. The H. influenzae is the first organism whose genome was completely sequenced and annotated. Here, we have extensively analyzed the genome of H. influenzae using availab…
Cellulose can be liquefied in ethylene glycol at 180 °C, using 6.7 mol % 1-(1-alkylsulfonic)-3-methylimidazolium chloride ionic liquids as catalysts. The maximum liquefied product yields of 0.3436 and 0.3046 g/g of cellulose were achieved after 20 h at 180 °C using 1-(1-proylsulfonic)-3-methylimidazolium chloride and…
OBJECTIVES: The hypolipidemic effects of di(2-ethylhexyl)phthalate (DEHP) exposure in humans have not been investigated. And the influences of maternal prenatal DEHP exposure on birth outcomes are not well-known. We aimed to estimate prenatal DEHP exposure in maternal blood, and evaluate its relationships to maternal…
A negative capacitance field‐effect transistor (FET) with sub‐60 mV/decade subthreshold slope (SS) at different temperatures (i.e. 14.8 mV/decade at 300 K, 15.7 mV/decade at 360 K and 24.3 mV/decade at 400 K) is experimentally demonstrated. A detailed account of the fabrication process of a negative capacitor is first…
The mechanical behaviour of gelatine gels as a function of test rate and gelatine concentration was determined through lubricated uniaxial compression and wire cutting tests. Similar to other reported literature, it was observed that the fracture stress and strain of the gels were strongly strain rate dependent wherea…
Zinc chromite (ZnCr2O4) nanocrystalline spinel material was synthesized through hydrothermal method by using zinc nitrate 6-hydrate and chromium nitrate 9-hydrate as precursors. The synthesized material was characterized for phase identification, crystallinity and surface morphology by X-ray diffraction (XRD) and scan…
Sustainable development and continued prosperity of humanity hinge on the availability of renewable energy sources on a terawatts scale. In the long run, solar energy is the only source that can meet this daunting demand. Widespread utilization of solar energy faces challenges as a result of its diffusive (hence low e…
Using density functional theory, we systematically compute and investigate the binding enthalpies of 14 different small molecules in a series of isostructural metal–organic frameworks, M-MOF-74, with M = Mg, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn. The small molecules we consider include major flue-gas components, trace…
Se produjeron microfibras de bagazo de caña de azúcar que exhiben repelencia al agua tras su pretratamiento y modificación superficial con hexadeciltrimetoxisilano. Fueron estudiados tres pretratamientos para llevar a cabo deslignificación, remoción de hemicelulosa y exposición superficial de celulosa: tratamiento con…
C. procera in India holds a pride of place largely because of its pharmacological uses and economic values. Arka (C. procera) an important drug of Ayurveda is known from the earliest time. Traditionally Calotropis is used alone or with other medicines to treat common disease such as fevers, rheumatism, indigestion, co…
High-quality carbon nanotubes (CNTs) are promising materials in many applications. However, current chemical vapor deposition (CVD) methods for CNT synthesis suffer from the discrepancy between the quality and yield of CNTs: Low-quality CNTs can be synthesized with high yield, while high-quality CNTs can only be synth…
A good understanding of the mechanism of interaction between quantum dots (QDs) and heavy metal ions is essential for the design of more effective sensor systems. In this work, CE was introduced to explore how l-cysteine-capped-CdTe QDs (l-cys-CdTe QDs) interacts with Hg(2+) . The change in electrophoretic mobility ca…
