To understand the fate of anionic macromolecular species when injected into blood, poly(acrylic acid) and poly(L-lysine citramide) polyanions, with better charge densities, and the poly(L-lysine) polycation were used as models of negatively charged polymer—drug conjugates and positively charged blood proteins, respect…
Tanning of animal hides produces leather, a durable, flexible material that is stabilized against putrefaction. Chrome-tanned wet blue, aldehyde crosslinked wet white, and vegetable tanned hides are major contributors to current leather production. Although the chemistries involved are significantly different, the pro…
X-ray powder diffraction, permeability, magnetization and differential scanning calorimetry measurements were carried out on the magnetic shape memory alloys Ni2MnGa1−xCux (0 ≤ x ≤ 0.25). On the basis of the experimental results, the phase diagram in the temperature– concentration plane was determined for this alloy s…
The physical, electrical, and reliability characteristics of various Copper (Cu) barrier films, including SiC, SiCN, SiCO, SiCNO, and SiN, were investigated. The experimental results indicate that the SiN film is the best barrier film against Cu diffusion, adheres strongly to Cu film, and exhibits reliable electromigr…
The review provides a general idea about the types of metallic alloys and the pure metals used as implant materials in dental and orthopedic surgery. Their corrosive behavior in both real solutions and various media that model human biological fluids is described. Based on the literature data, it is concluded that mul…
The analytic survey of experimental and theoretical studies of the magnetic anisotropy of ferromagnetic shape memory alloys (FSMAs) is presented. The interdependence between the magnetic anisotropy of FSMAs, their lattice parameters, microstructure, and magnetostrain properties is considered. The temperature dependenc…
Effects of citric acid on crystalline habit and crystal morphology of gypsum dihydrate were analyzed in great detail. The retarding mechanism of citric acid was also discussed from the standpoint of crystal growth by use of Scanning Electric Microscope and X-ray Photo Technology. The results shows that due to the comp…
Cellulose nanocrystals, a potential base material for green nanocomposites, are ordered bundles of cellulose chains. The properties of these chains have been studied for many years using atomic-scale modeling. However, model predictions are difficult to interpret because of the significant dependence of predicted prop…
Aligned cellulose nanocrystals/cellulose coelectrospun nanofibers were successfully prepared by using a home-built coelectrospinning and collection system. Cellulose I was dissolved in N-methyl morpholine oxide at 120°C and diluted with dimethyl sulfoxide, which was used in the external concentric capillary needle as…
The objective of the work was to study the influence of the exposed area of the working electrode on the corrosion behavior of a duplex stainless steel (EN 1.4462) in a 992 g/l LiBr solution under static conditions (without cavitation) and dynamic conditions (with cavitation) at 25 ºC. The Potentiodynamic Cyclic curve…
Multilayered films of Au/ZnO were prepared by physical vapor deposition. Varying the Au thickness, tAu, and the number of bilayers, n, allowed us to investigate the role of these parameters on the sample structural and electronic properties. X-ray diffraction, X-ray absorption spectroscopy, grazing incidence small ang…
In the Ag–Ba–Si system the clathrate type I solid solution, Ba 8 Ag x Si 46- x , ranges at 800 °C from Ba 8 Ag 4.3 Si 41.7 [ a = 1.04309(3) nm] to Ba 8 Ag 5.4 Si 40.6 [ a = 1.04613(5) nm]. For all clathrate compositions in this homogeneity region (4.3 ≤ x ≤5.4) cubic primitive symmetry with space group P m 3 n was con…
Grain boundary phenomena strongly depend on grain boundary structure and characteristics, i.e. coincidence site lattice (CSL) boundaries, as contrasted with random boundaries, are highly resistant to intergranular degradation. Grain boundary engineering (GBE) primarily intends to prevent the initiation and propagation…
This paper presents a novel state of the art equipment for core loss measurements under high frequency and non-sinusoidal excitations. Sinusoidal high frequency measurements are performed using a commercial test system especially designed for high frequency testing. Comparative measurements are performed over a wide r…
The stress-strain characteristics of composite films based on methyl cellulose and poly(vinylformamide) prepared from solutions of polymer blends in water and dimethyl sulfoxide are studied. The temperature of relaxation transitions in the mixed films and the concentration interval where the polymers are compatible ar…
The aerosol deposition of detonation nanodiamonds (DNDs) on a silicon substrate is comprehensively studied, and the possibility of subsequent growth of nanocrystalline diamond films and isolated particles on substrates coated with DNDs is demonstrated. It is shown that a change in the deposition time and the weight co…
(100)/(001)-oriented 2 μm-thick Pb(Ti, Zr)O3, films with the Zr/(Zr + Ti) ratio of 0.39 and 0.50 were prepared by metalorganic chemical vapor deposition. The volume fraction of (001)-oriented domain, Vc, was controlled by selecting the kinds of substrates with different thermal expansion coefficient. The effective pie…
As the scaling of silicon complementary metal-oxide-semiconductor devices becomes more and more challenging, both innovative device structures and new materials with high carrier mobility are needed to continue improving device performances. A metal-oxide-semiconductor field-effect transistor with germanium channel cu…
2010 marked the 30th anniversary of the High-Electron Mobility Transistor (HEMT). The HEMT represented a triumph for the, at the time, relatively new concept of bandgap engineering and nascent molecular beam epitaxy technology. The HEMT showcased the outstanding electron transport characteristics of two-dimensional el…
In this study, stress-relaxation performance of HDPE-based injection-molded composites containing four types of natural fibers (i.e., wood flour, rice hulls, newsprint, and kenaf fiber) at 25 and 50 wt% contents, and the effect of prescribed strain levels were investigated. The results indicated that incorporating mor…
