Hypervelocity gouging occurs in material systems with high sliding speeds and has been observed in rocket sleds, light-gas guns, and railguns. Gouging takes the form of teardrop-shaped craters on the rail surface and usually occurs above a threshold speed that is material-pair dependent. The best predictive tools deve…
Biomaterials are used in regenerative medicine for induced autoregeneration and tissue engineering. This is often challenging, however, due to difficulties in tailoring and controlling the respective material properties. Since functionalization is expected to offer better control, in this study gelatin chains were mod…
This study examined the influence of phosphorus addition on the corrosion resistance of carbon steel for a flue gas desulfurization (FGD) system using electrochemical methods, such as potentiodynamic polarization tests and electrochemical impedance spectroscopy (EIS) in 10 wt% sulfuric acid (H2SO4) solution at room te…
To understand in vitro and in vivo uptake of nanoparticle and enrichment is important for the improvement of therapeutic drug delivery. mPEG-PCL is a kind of biodegradable and biocompatible polymer suitable as a drug carrier, and many studies have been done to improve its bioavailability and loading capability. In thi…
From the ground up: In the hierarchical organization of cyanurate 1 and π-extended tetrathiafulvalene (π-exTTF) 2—an example of the controlled one-, two, and three-dimensional assembly of nonplanar building blocks on different scales—highly ordered lamellar crystalline packing based on π–π interactions between π-exTTF…
The growth mechanism of one-dimensional metal oxide nanotubular structures is of tremendous current interest to tailor materials using "green" synthetic procedures for emerging industries in alternative energy and biomaterials. In this study, ZrO(2)-modified TiO(2) nanorods and tubular structures were successfully syn…
Abstract Surface texturing of silicon wafer is a key step to enhance light absorption and to improve the solar cell performances. While alkaline‐texturing of single crystalline silicon wafers was well established, no efficient chemical solution has been successfully developed for multicrystalline silicon wafers. Thus,…
An examination is presented of the relevance of luxury to the wool textile and garment supply chain. This examination leads to a review of the concept and importance of fabric handle as a means of defining important aspects of fabric quality. Examples are given for woven fabrics of the general relationships between su…
Temperature-dependent formation of gelatin−poly(galacturonic acid) (PGA) multilayer films based on the layer-by-layer approach and their stability to changes in temperature, pH, and NaCl concentration were investigated for the first time using quartz crystal microbalance with dissipation monitoring (QCMD). Changes in…
Many traditional medicines have demonstrated immune activity, however, research has largely neglected their effects on cell adhesion molecules (CAMs). This review reports on extracts from 37 medicinal plant species, similar to or replicating traditional preparations, that up- or downregulate either gene or protein act…
Abstract Monodisperse gold nanoparticles (AuNPs) were obtained by hydrolytic decomposition of a new molecular precursor, tetramethylammonium bis(trifluoromethyl)aurate(I), [NMe 4 ][Au(CF 3 ) 2 ], which has been characterised by spectroscopic and single‐crystal X‐ray diffraction analyses. On account of the simple and h…
The structure and dielectric properties of Sm 1.5 Sr 0.5 Ni 1− x Al x O 4 ( x = 0.3, 0.5) ceramics were presented. A single orthorhombic phase was obtained in Sm 1.5 Sr 0.5 Ni 0.7 Al 0.3 O 4 ceramics, while minor impurities existed in Sm 1.5 Sr 0.5 Ni 0.5 Al 0.5 O 4 ceramics. Temperature stable giant dielectric respon…
Structural features of bimetallic nanoparticles synthesized in w/o microemulsion have been examined by using a coarse model solved by Monte Carlo simulations. The microemulsion was modeled as spherical droplets containing either two metal salts or reducing agent, and the processes occurring during the collision of the…
Polyphosphazenes elastomers have major utilization as fire resistant materials, gas kits, O-rings, electrical insulation, oil-resistant hoses, foam, ceramics, especially helicopter, air craft, aerospace, military and navy hardware applications. Tremendous achievements have been obtained for the synthesis and applicati…
Abstract Several biological organisms, from some sea shells to butterflies, exhibit beautiful and sophisticated organs, developed during the evolution of each species, which properties are defined by their nanostructures. The marine diatoms are microscopic algae enclosed between two valves of hydrated amorphous silica…
The TiO2 nanoparticles were modified by diblock copolymers, poly(methyl methacrylate)-b-polystyrene (PMMA-b-PS), via reversible addition-fragmentation chain transfer (RAFT) polymerization, and the epoxy nanocomposites containing different TiO2 and with different contents were prepared. Subsequently, the effects of TiO…
Chip level electromigration (EM) reliability is determined by: 1) the element level EM failure probability used for design guideline generation; and 2) the distribution of EM elements against design limits. Balancing these two factors is critical for a chip design to achieve the best performance while maintaining chip…
Undoped and Mn-doped cobalt ferrite (CoFe$_{2}$O$_{4}$) nanoparticles were synthesized and characterized for thermal conductivity and magnetic properties. Room temperature ferromagnetism and an increase in saturation magnetization due to Mn doping (65.4 emu/g for 3 at.% of Mn and 20.8 emu/g for undoped CoFe$_{2}$O$_{4…
Seven new ionic solids built on polyoxometalate anions and [Co(en) 3 ] 3+ cations, namely, [Co(en) 3 Mo 8 O 26 (H 3 O)(Cl)](DMF) 4 (H 2 O) (Co-Mo 8 -DMF), [α-PW 12 O 40 ][Co(en) 3 ]·6DMF (Co-W 12 P-DMF), [α-PW 12 O 40 ][Co(en) 3 ]·6DEF (Co-W 12 P-DEF), [α-PMo 12 O 40 ][Co(en) 3 ]·5.5DMF (Co-Mo 12 P-DMF), [α-PMo 12 O 4…
The swift heavy ion (SHI) irradiation induces weak ferrimagnetism (FM) in magnetically frustrated polycrystalline ${\text{BiMn}}_{2}{\text{O}}_{5}$ thin films. This is manifested from irradiation induced higher energetic configuration that accounts for evolution of the ${\text{Mn}}^{2+}$ state in the ${\text{Mn}}^{3+}…
