Significant progress has been made in recent studies of thermal and thermoelectric transport phenomena in nanostructures and low-dimensional systems. This article reviews several intriguing quantum and classical size effects on thermal and thermoelectric properties that have been predicted by theoretical calculations…
Substitutional charge disorder as in PbMg 1/3 Nb 2/3 O 3 , structural cation vacancies as in Sr x Ba 1-x Nb 2 O 6 and isovalent substitution of off-centered cations as in BaTi 1-x Sn x O 3 and BaTi 1-x Zr x O 3 give rise to quenched electric random-fields (RF s ), which we proposed to be at the origin of the peculiar…
A simple, cost-effective, and environmentally friendly approach to the aqueous-phase synthesis of silver (Ag) nanoparticles was demonstrated using silver nitrate (AgNO(3)) and freshly extracted egg white. The bio-conjugates were characterized by UV-visible spectroscopy, transmission electron microscopy, Fourier transf…
A new dielectric Fabry-Perot cavity was designed for a resonant enhancing optical absorption by a thin absorber layer embedded into the cavity. In this cavity, the front mirror is a subwavelength grating with $\sim 100$% retroreflection. For a HgCdTe absorber in a matching cavity of the new type, the design is shown t…
Understanding electron transport processes in molecular wires connected between contacts is a central focus in the field of molecular electronics. Especially, the dephasing effect causing tunneling-to-hopping transition has great importance from both applicational and fundamental points of view. We analyzed coherent a…
We report the effect of Sr substitution in an antiferromagnetic insulator LaMnAsO by the measurements of electrical resistivity, Hall coefficient, Seebeck coefficient and magnetization. Upon Sr doping to its limit x ∼0.10, the room temperature resistivity drops by five orders of magnitude down to ∼0.01Ω·cm, and the te…
A steady shear flow can drive supercooled liquids into a non-equilibrium state. Using molecular dynamics simulations under steady shear flow superimposed with oscillatory shear strain for a probe, non-equilibrium mechanical responses are studied for a model supercooled liquid composed of binary soft spheres. We found…
Transistors are the fundamental building block of modern electronic devices. So far, all transistors are based on various types of semiconductor junctions. The most common bipolar-junction transistors and metal-oxide-semiconductor field-effect transistors contain p-n junctions to control the current, depending on appl…
Lithium tungsten borate glass of the composition (0.56-x)B2O3–0.4Li2O–xZnO–0.04WO3 (0 ≤ x ≤ 0.1 mol. %) is prepared for photonics applications. The glass is doped with ZnO to tune the glass absorption characteristics in a wide spectrum range (200–2500 nm). Chemical bond approach, including chemical structure, electron…
The present review summarizes, in a detailed introduction, the synthesis techniques, structures, classifications, uses, properties, and applications of ferrite materials in the fields of sensors. Morphological and structural studies of ferrite materials were performed. A great advantage of ferrites is their porosity,…

Synthetic aromatic polyarylether ketones are known for their high performance applications. Poly(ether ether ketone) is an important material which is most widely used in such aggressive environments as nuclear plants, oil and geothermal wells, chemical plants, and high-pressure steam valves. Considering the wide rang…
CO is a toxic and detrimental air pollutant. It not only affects human beings but also vegetation and indirectly increases global warming. An estimate has shown that vehicular exhaust contributes about 64% of the CO pollution in developed countries. Due to the exponentially increasing number of automobiles on roads, C…
Due to the widespread use of nanomaterials in medical, industrial and military applications, the question as to whether nanoparticles (NPs) cause harmful disturbances in human health, especially on the reproductive system, remains a matter of concern. In this review, we focus mainly on the in vivo and in vitro effects…
The water-cooled thermomechanical control process (TMCP) is a technology for improving the strength and toughness of water-cooled steel plates, while allowing control of the microstructure, phase transformation and rolling. This review describes metallurgical aspects of the microalloying of steel, such as niobium addi…
In this study, we report the functionalization of silica nanoparticles with highly photoreactive phenyl azido groups and their utility as a negatively charged building block for layer-by-layer (LbL) electrostatic assembly to produce a stable silica nanoparticle coating. Azido-terminated silica nanoparticles were prepa…
In this review article we present a general overview of the recent progress in the newly developing area of the study of protein‐ligand interaction by surface enhanced Raman spectroscopy (SERS). Since its first observation in 1977, SERS have been fast developing into an analytical tool for trace detection of molecular…
This paper reviews the applications of shear thickening fluids (STF) to enhance the impact resistance behavior of textile materials. The mechanism of shear thickening has been presented in the form of ‘order disorder theory’ and ‘hydrodynamic clustering’. The applications of different shear thickening fluids on fabric…
