Materials engineering plays a key role in the field of energy storage. In particular, engineering materials at the nanoscale offers unique properties resulting in high performance electrodes and electrolytes in various energy storage devices. Consequently, considerable efforts have been made in recent years to fulfill…
Gold nanorods have received much attention due to their unique optical and electronic properties which are dependent on their shape, size, and aspect ratio. This article covers in detail the synthesis, functionalization, self-assembly, and sensing applications of gold nanorods. The synthesis of three major types of ro…
We find the form of three-point correlation functions of traceless symmetric conserved currents of arbitrary spin in d-dimensional conformal field theory (CFT). These are fixed up to several constants by conformal symmetry and current conservation conditions. We present generating functionals for all structures in arb…

Two dimensional transient modelling of the flow and heat transfer in an idealized Trombe wall system was performed for a fixed set of physical dimensions. The governing equations were solved using multiphysics software. Buoyancy and thermal accumulation in a brick wall are the main effects considered. During operation…
A vector calculus for nonlocal operators is developed, including the definition of nonlocal divergence, gradient, and curl operators and the derivation of the corresponding adjoint operators. Nonlocal analogs of several theorems and identities of the vector calculus for differential operators are also presented. Relat…
Recently, it was shown that human dielectric properties can be mapped using MRI. This method, named electrical properties mapping (EPT),relies on measurements of the B1+ amplitude and its phase. This phase, however, cannot be measured directly; therefore, the assumptionthat the transceive phase is twice the B1+ phase…
First brought to attention in 1939, G. hominis (also known as colonic uke) is a natural parasite of the colon of the pig, and is occasionally involved in human infection (found in the human cecum).
This paper deals with application of micromagnetic inspection of surface integrity after turning bearing steel 100Cr6 in dependence on increasing tool wear.This paper indicates influence of tool wear on the selected parameters of Barkhausen noise (RMS value, peak position).The analysis also contains measurement of res…
Twin screw extruders (TSEs) are used to process virtually every type of plastic that is used today. The goal of this chapter is to dene how twin screw extrusion (TSEs) can be used to process thermoplastic polyurethane (TPU) formulations that contain additive and llers into pellets and shapes. Some simple formulas ar…
The unique combination of the properties of toughness, ¥exibility, abrasion resistance, and solvent resistance, plus the ability to be custom tailored, has led to the widespread and continually increasing use of urethanes. Typical uses include leather coatings, fabric coatings and adhesives, industrial maintenance and…
Biomaterial research in the medical device industry is no longer exclusively centered on biostable materials intended for long-term deployment in the body. Interest in growing elds such as tissue engineering and controlled release has prompted the development of polymeric materials that degrade at a controlled rate i…
The blending of polyolens such as polyethylene or polypropylene with thermoplastic polyurethanes (TPUs) has been a long-sought endeavor. If nothing else, one of the primary goals has been the availability of economically attractive polymer blends with properties close or equal to the best of the polyurethane componen…

These include • Adhesio…
In Brief The efficacy for radiological decontamination of the laboratory standard fume hood as constructed of stainless steel, compared to that of powder-coated carbon steel is described. While the chemical inertness of powder-coated surfaces is good, faced with everyday abrasion, aggressive inorganic solutions and va…
We have constructed statistical models that predict thermal resistance after fouling layer formation in a heat exchanger, in which a slurry of stearic acid in toluene was cooled. Chemoinformatics was used, and the initial rate of increase in thermal resistance (d U –1 /d t ) was calculated from experimental conditions…
We investigate--using Monte Carlo computer simulations--the phase behaviour of dimeric colloidal molecules on periodic substrates with square symmetry. The molecules are formed in a two-dimensional suspension of like charged colloids subject to periodic external confinement, which can be experimentally realized by opt…
A new Cyclotella species, C. iwatensis is described from freshwater sediment of the Mio-Pliocene Masuzawa Formation, Shizukuishi Town, Iwate Prefecture, Japan. The new species is characterized by a round central area of the valve face with a radial colliculation and a jagged boundary, marginal striae of different leng…
Six crystal-field energy levels and three electron paramagnetic resonance (EPR) data [g factor and hyperfine structure constants A(171Yb3+) and A(173Yb3+)] for trivalent ytterbium (Yb3+) ions in the cubic β-lead fluoride (β-PbF2) crystal are calculated by using a diagonalization (of energy matrix) method. In the metho…
