With the aim that to confirm the need for humidity control in the environment in which textile sample are visually and instrumentally analyzed, three different pre-conditioned fabrics sample of cotton, polyester and silk were treated at a fix temperature of 21?C. The relative humidity adjusted to four levels: 55%, 65%…
Crystallization kinetics and stability are very important and essential parameters for glasses and glass ceramics. These parameters are highly dependent on initial composition as well as processing conditions. Thus, the role of modifier cation on thermal parameters have been studied for AO-SiO 2 -B 2 O 3 -Y 2 O 3 (A =…
Different derivatives of the Schiff base (SB) N,N′-bis(2-hydroxybenzylidene)-2,2,-dimethylpropane-1,3,-diamine, LH2, have been used to obtain a series of compounds of which we here report the synthesis, structural determination and magnetic study. [Mn(SB)(H2O)]ClO4 and [NEt4]3[Fe(CN)6] react in methanol to give the ci…
The name of Vertisol is derived from Latin “vertere” meaning to invert. This case restricts development of soil horizons in profile. These soils have the capacity to swell and shrink, inducing cracks in the upper parts of the soil and distinctive soil structure throughout the soil. The formation of these specific feat…
We report a stainless steel/multi walled carbon nanotubes/polyaniline (SLS/MWCNTs/PANI) capacitor electrode capable of operating in a physiological electrolyte and in serum. The specific capacitance of SLS/MWCNTs/PANI reaches 401 F g(-1) in the physiological electrolyte and 326 F g(-1) in serum. The capacity loss at 6…
The main goal of this work was to use rice straw (RS) in the production of environmentally sound composites using corn based adhesives (CA). Treatments of RS with NaOH and hot-water were undertaken to evaluate the effect of such treatments on the performance of produced composites. The influence of composite density,…
Finite element modeling based on solving the Nernst-Planck equation was used to describe the evolution of current densities and pH distribution at the surface of a bimetallic system. This system consisted of five single copper particles fabricated on isolated, thin-film aluminum electrodes exposed to dilute aqueous ch…
The aggregates of a cationic polythiophene (PT1) formed in poor solvent in the presence of sugars showed the distinct circular dichroism activity, the intensity being well correlated with the specific optical rotation [α] of sugars: therefore, the present system is useful as a novel sugar structure reading-out method.
This paper presents a novel approach to reduce the water vapor transmission rate (WVTR) and water absorbance of wheat gluten/paperboard laminates by introducing a hydrophobic component (oleic acid (OA)) into the hydrophilic plasticizer (glycerol). Whereas the paperboard showed immeasurably high WVTR, the laminate with…
Porous SiC ceramics were prepared at 1900–2000°C without holding time at 50–200°C/min under a pressure of 15 MPa in Ar with Al2O3, Y2O3, and AlN additives by spark plasma sintering. The effects of heating rate, heating temperature, and sintering additive on the porosity, pore size, microstructure, and flexural strengt…
Hierarchical nanofibrous titania–carbon composite material deposited with silver nanoparticles derived from a natural cellulose substance (filter paper) was designed and fabricated. ICP-MS analysis showed that the content of deposited silver nanoparticles is as high as (9.5 ± 0.1) wt%, and TEM observation revealed tha…
A simple polymerisation strategy allows water solubilisation of chromophores for biophotonics, with good conservation of their fluorescence quantum-yield. Preliminary investigations show that the resulting objects are valuable candidates for photodynamic therapy and two-photon fluorescence imaging.
Solution processed graphene oxide (GO) sheets are electronically insulating and are generally reduced by chemical treatment or heat treatment in a reducing environment to recover their electronic properties, forming reduced graphene oxide (rGO). Here, GO sheets were photocatalytically reduced using 5-(4-hydroxyphenyl)…
One problem with research on nanoparticles production is the lack of scalability from laboratory to levels of production necessary for commercial or industrial applications at low cost. Several methods, which often involve the use of chemicals, have been employed to produce silica nanoparticles from rice husk, but out…
Using molecular dynamics (MD) simulations, we report a displacing method to release encapsulated molecules out of open-ended single-walled carbon nanotubes (SWNTs). The simulations indicated that encapsulated molecules such as water, DNA and indomethacin (IMT) molecules would be expelled from SWNTs by fillers such as…
Well-formed, highly crystalline potassium titanate whiskers were successfully grown by the KCl flux cooling method at a holding temperature of 800 °C using metallic titanium materials. Of primary importance were the metallic Ti spheres and potassium chloride powders that were used as the starting materials for growth…
We introduce a novel procedure for producing flexible transparent conductive graphene films. The synthetic procedure includes a solution-processed chemical reduction and an anodized aluminum oxide (AAO) membrane filter-assisted thermal reduction. The final flexible transparent graphene films produced by this method ex…
The shock-wave phenomena generated by femtosecond laser pulses in aluminum films 0.5 to 1.2 μm in thickness were studied. The shock compression is elastic up to 20.5 GPa under these conditions. The spall strength of aluminum at strain rates of about 109 s-1 is comparable with its ideal tensile strength and is in good…
The influence of texture on the bendability in Cu–Ni–Si alloys was examined by using an age-hardened polycrystalline strip with various recrystallization textures. In multiple samples manufactured by adjusting conditions of rolling and heat treatment, the Cube orientation {100}<001>, the RD-rotated Cube orientation {0…
Ti–6Al–4V alloys modified with minor amounts of boron (B) were prepared, and two types of microstructures, a full lamellar microstructure and an equiaxed microstructure, were generated through combinations of hot-deformation and heat treatments. The beneficial effect of adding a minor amount of B in refining microstru…
