Microporous structures are usually designed for hemostatic agents to dehydrate blood and thus accelerate the natural clotting process. We have developed gelatin-based fibrous membranes by co-electrospinning with a hydrophobic protein, zein, for hemostatic dressings. The hybrid gelatin/zein fibers showed structural int…
We suggest a more nuanced view of the merit and utility of generalized gradient approximations (GGAs) for the noninteracting kinetic energy (KE) than the critique of Xia and Carter (XC) [Phys. Rev. B 91, 045124 (2015)]. Specifically, the multiple valuedness of the Pauli term enhancement factor (denoted $G[n]$ by XC) w…
This paper describes a lamination method of commercially produced silica aerogel composite and investigates its suitability for thermal insulation within protective footwear applications for severe cold and extreme high-altitude environments. A silica aerogel composite was used with a thickness of 2.7 mm and mass per…
Tm-doped fiber laser or amplifier can be applied in varied adverse environments. In this work, we demonstrate the pump bleaching of Tm-doped silica fiber with 793nm pump source under gamma-ray irradiation in the range 50Gy-675Gy. The recovery time, the fiber slope efficiency and the fiber cladding absorption spectra a…
Abstract The synthesis of a new mixed metal–organic framework (M′MOF) has been accomplished by the metalloligand approach. [NaCu(2,4‐HPdc)(2,4‐Pdc)] (2,4‐H2Pdc = pyridine‐2,4‐dicarboxylic acid) has been obtained from the hydrothermal reaction of the metalloligand [Cu(2,4‐HPdc)2(H2O)2] NaOH, and a transition metal salt…
We combine supramolecular host–guest interactions of β-cyclodextrin (CD) with light-induced Diels–Alder reactions of 2-methoxy-6-methylbenzaldehyde (photoenol, PE) for the formation of multiblock copolymers. Via the synthesis of a new bifunctional chain transfer agent (CTA) and subsequent reversible addition–fragmenta…
Microwave dielectric ceramics of (1− x )Ba(Mg 1/3 Nb 2/3 )O 3 ‐ x BaSnO 3 [(1− x ) BMN ‐ x BS] with high quality factors was synthesized by the solid‐state reaction method. The effects of BaSnO 3 additions ( x = 0–0.2) on the sinterability, crystal structures, microwave dielectric properties, and microwave dielectric…
Spatiotemporal nanofocusing of ultrafast surface plasmon polaritons (SPPs) coupled on a metal Au tapered tip with a curvature radius of a few tens of nanometers is deterministically controlled based on the measured plasmon response function. We control the SPP pulse shape and the second harmonic generation at the apex…
The voltammetric (CV and DPV) behavior of multi-walled carbon nanotube/Nafion composite coupled with a glassy carbon electrode was investigated for the determination of 2,4-dichlorophenol. The structural and morphological evaluation by XRD and FESEM revealed that the acid treated MWCNT retained their morphology withou…
The effects of constrained sample dimensions on the mechanical behavior of crystalline materials have been extensively investigated. However, there is no clear understanding of these effects in nano-sized amorphous samples. Herein, nanoindentation together with finite element simulations are used to compare the proper…
The new amphiphilic BODPY-porphyrin conjugate BZnPP and its precursor BZnPH were synthesised, and their linear and two-photon photophysical properties, together with their cellular uptake and photo-cytotoxicity, were studied. This amphiphilic conjugate consists of a hydrophobic BODIPY moiety and a hydrophilic tetra(et…
PURPOSE: A type of in vivo dosimeter, an optically stimulated luminescent dosimeter, OSLD, may have dose sensitivity that depends on the angle of incidence of radiation. This work measures how angular dependence of a nanoDot changes with the geometry of the phantom in which irradiation occurs and with the intrinsic st…
A synthetic strategy for functionalization of the three vertices of o-carborane and the attachment of the obtained triped to the solid support was developed. Further functionalization of the triped with short DNA sequences by automated DNA synthesis was achieved. The proposed methodology is a first example of boron cl…
Hyperthermia is considered the fifth pillar of cancer treatment. It induces cancer cell apoptosis, however, its molecular mechanisms remain unclear. In the present study, the role of Survivin in hyperthermia-induced apoptosis in esophageal cancer was investigated. Different temperatures were used to treat EC109 esopha…
We show that correlated pair tunneling drives a phase transition to a twisted superfluid with a complex order parameter. This unconventional superfluid phase spontaneously breaks the time-reversal symmetry and is characterized by a twisting of the complex phase angle between adjacent lattice sites. We discuss the enti…
Based on Fresnel diffraction from phase steps, we present an optical method for real-time monitoring and measurement of thickness during the wet etching of transparent materials. It is shown experimentally that during the etching process, the visibility of diffraction fringes varies periodically with time (thickness)…
The intermixing of dissimilar grades of steel in tundish during the ladle change‐over is a problem of growing interest. During sequential casting of different grades, it is important that the intermixing of the grades is kept to a minimum. Present work deals with computational and water model studies of the three‐dime…
Abstract Lithium‐rich layered oxides are promising cathode materials for lithium‐ion batteries and exhibit a high reversible capacity exceeding 250 mAh g−1. However, voltage fade is the major problem that needs to be overcome before they can find practical applications. Here, Li1.2Mn0.54Ni0.13Co0.13O2 (LLMO) oxides ar…
This article reports the latest developments of our theoretical studies of gas cluster bombardment of model macromolecular samples using molecular dynamics simulations. Here, we perform a detailed comparison of the effects of the sample molecular weight, the Ar cluster incidence angle (45° vs 0°), and the cluster natu…
Quantifying how the rugged nature of the underlying free-energy landscape determines the entropic cost a protein must incur upon folding and ligand binding is a challenging problem. Here, we present a novel computational approach that dissects the protein configurational entropy on the basis of the classification of p…
