In recent years, with the requirements of environmental protection of packaging materials improve, biodegradable materials more and more attention to. This paper to waste as raw materials, and by the synthesis of the biodegradable packaging material performance for research. The results show that: to recycle waste as…
Abstract Tasar silk is a variety of non‐mulberry silk indigenous to the Indian subcontinent. We present the measured frequency‐dependent viscoelastic moduli of Tasar regenerated silk fibroin (RSF) solution using optical tweezers at two concentrations (0.16% and 0.25% w/v) and extend these measurements to the low frequ…
Since the discovery of graphene, many efforts have been done to modify the graphene structure for integrating this novel material to nanoelectronics, fuel cells, energy storage devices and in many other applications. This leads to the production of different types of graphene-based materials, which possess properties…
We describe the direct measurement of actual transmittance of sodium samples with thickness of a 2 mm and 3 mm in a spectral range >115 nm, resulting in >50% transmittance of 3 mm thick solid and liquid sodium samples including transmission of a pair of the windows at the wavelength of 120 nm, giving an extinction coe…
Silver-based nanocomposites are known to act as biocides against a series of microorganisms and are largely studied as an alternative to substitute conventional antibiotics that show decreasing efficacy. In this work, an eco-friendly method to synthesize silver nanoparticles assembled on the surface of hexaniobate cry…
Morphological inhomogeneity between electrodeposited cuprous oxide (Cu 2 O) thin films on nominally equivalent tin-doped indium oxide (ITO) electrodes under identical deposition conditions is reported. Dependence of the Cu 2 O photocurrent generation ability on thin-film morphology is also described. Films exhibiting…
Mechanisms of fire retardancy of intumescent Gaialene® (a polypropylene-grafted starch, containing ammonium polyphosphate as flame retardant) exhibiting high performance (60% reduction of the peak of heat release rate at 35 kW/m 2 , high limiting oxygen index (30 vol% O 2 ), and UL-94 V0 ranking at 1.6 mm and V2 at 0.…
Using reverse nonequilibrium molecular dynamics simulations the influence of intermolecular bridges on the thermal conductivity (λ) in carbon nanotube (CNT) bundles has been investigated. The chosen cross linkers (CH2, O, CO) strengthen the transversal energy transport relative to the one in CNT bundles without bridge…
Structural, electronic and optical properties of the antisite BiMO4 defect in Bi12MO20 sillenites (BMO, M=Si, Ge, Ti) were investigated using density functional theory. The defect is studied in neutral, positively and negatively charged states. It is demonstrated that within the neutral defect the Bi 6s(2) lone pair i…
He atoms introduced into materials may lead them to fracture intergranularly, and understanding such an effect is a key issue in the design of future fusion reactors. In the current study, we investigated the decrease of grain boundary (GB) strength caused by He segregation at several kinds of α -Fe GBs by exploiting…
Abstract A solid oxide fuel cell in operando is a complex multiphasic entity under electrical polarization and operating at high temperatures. In this work, we reproduce these conditions while studying transition metal redox chemistry in situ at the cathode. This was achieved by building a furnace that allowed for X‐r…
A light-emitting diode is fabricated and characterized on a semiconducting serpentine CNT which has many parallel segments with identical chirality. Compared with the individual CNT and CNT-film devices, the device with parallel segments shows improvement of an order of magnitude in current, significantly larger elect…
Detailed thermal and mechanical finite element analyses of woven composites are computationally challenging due to the heterogeneous nature and the geometrical complexity of the composite. In this paper two finite element three-dimensional image-based models at different length scales are used to evaluate the thermal…
Simple model systems with short-range attractive potentials have turned out to play a crucial role in determining theoretically the phase behavior of proteins or colloids. However, as pointed out by D. Gazzillo [J. Chem. Phys. 134, 124504 (2011)], one of these widely used model potentials, namely, the attractive hard-…
Recent investigations in R2Fe17 intermetallic compounds have evidenced that these materials present a moderate magnetocaloric effect (MCE) near room temperature. A series of accurate magnetization measurements was carried out to show that the value of the demagnetizing factor has a significant influence on the absolut…
Nanostructured CaCO3 crystals are produced in vitro by adding the acid-soluble organic matrix (SOM) extracted from the nacreous layer of Pinctada margaritifera pearl oyster shell to a supersaturated solution of calcium carbonate. For SOM concentrations above 25 ppm, the produced calcite crystals show two structural fe…
ABSTRACT The sheets of polycarbonate (PC)/polyethylene (PE) in situ microfibrillar composites are successfully prepared directly through multistage stretching extrusion with an assembly of laminating‐multiplying elements (LMEs) instead of the secondary processing. The morphological development of the PC dispersed phas…
Bioinspired bead-on-string silkworm silk (BBS) effectively modulates capillary adhesion for strong water-capturing abilities and mechanical properties compared to natural silkworm silk (NSS).
The solubilities of indole-2-carboxylilc acid in ten pure solvents including water, methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, ethyl acetate, dichloromethane, toluene, and 1,4-dioxane were measured from (278.15 to 360.15) K at atmospheric pressure using the synthetic method. The solubility was determined by…
Abstract There is no method that allows the simultaneous preparation of titanium and aluminum, so that both phases can be investigated by means of scanning electron microscopy (SEM) at the same time. Especially local orientation measurements by electron back scatter diffraction (EBSD) are challenging as they require a…
