Thermal contact resistance(TCR)is a hot topic in electronics cooling,cryogenic superconducting thin films,etc.In this paper,the fundamental research method,metrology macro-and nanotechnology,and diminishing method for TCR are reviewed.In order to investigate the heat transfer mechanism of TCR,the scattering and radiat…
In order to eliminate the risk on the safe operation of power grid caused by the internal defects of composite insulators,a non-destructive method using phased array ultrasonic detectors for detecting the flaw in the insulator was presented under four circumstances of normal bonding,middle bubble,central section defec…
The present communication is aimed at comparing the molecular structural properties, vibrational and energetic data of 2- and 4- quinazolinone, the two isomers of Quinazolinone, a biologically active hetrocyclic compound, in gas phase, due to their pharmacological activities and applications . The ground state propert…
First-principles calculations of optical and mechanical properties of LiBX2 (B= Ga,In; X= S,Se,Te) are performed using plane-wave pseudopotential method. According to the order of band gaps, the order of laser induced damage thresholds is LiGaS2 > LiInS2 > LiGaSe2 > LiInSe2 > LiGaTe2 > LiInTe2. The elas…
Nanoarchitectonics1 is a term coined at the National Institute for Materials Science (NIMS) in Japan to define the preparation of materials by arranging structural units at the nanoscale using different experimental approaches, such as physical and/or chemical manipulation of atoms and molecules, fi...
Various shapes of ZnO; multi-petals, rod and spherical were prepared and then applied on cotton fabric for UV-blocking. The ZnO particles were investigated by XRD and SEM. The mixture solution of ZnO with polyvinyl alcohol was applied onto cotton fabrics via electrospinning. The characteristics of the fabric coating w…

In this paper, we report a successful growth of zinc oxide nanowire networks by simple thermal evaporation process using metallic zinc powder in the presence of oxygen. The morphological investigations of the synthesized nanowire networks are conducted by using field emission scanning electron microscopy (FESEM) which…
The study of an industrial unit of biotrickling filter for the treatment of the exhaust gases of a flexographic facility was investigated over a 2-year period with the objective to meet the volatile organic compound (VOC) regulatory emission limits. Increasing the water flow rate from 2 to 40 m(3) h(-1) improved the p…
CoMn2O4 (cobalt manganite) nanoparticles encapsulated in amorphous SiO2 cages were prepared by a wet chemical method. Two different structures of CoMn2O4 nanoparticles, cubic and tetragonal, were observed in the X-ray diffraction patterns. CoMn2O4 crystals usually form a tetragonal structure with Jahn-Teller distortio…
This note is concerned with a nonlinear diffusion problem of phase-field type, consisting of a parabolic system of two partial differential equations, complemented by Neumann homogeneous boundary conditions and initial conditions. The system arises from a model of two-species phase segregation on an atomic lattice [Po…
Gearbox top cover is a vital component of horizontally split integrally geared centrifugal compressor. Reliability of top cover is directly related to the structural rigidity and structural integrity of compressor. Assuming that the top cover is designed within the mechanical limits of its construction material, one o…
The variation of absorption coefficient with different soil samples of various chemical compositions and physical properties has been investigated, using gamma radiation method. For this work, soil Samples were collected from different locations of Nanded and Latur district from Maharastra and Bidar district from Karn…
Five profi les of lowland Vertisols—namely, Ban Mi (Bm1, Bm2), Chong Khae (Ck), Lop Buri (Lb) and Wattana (Wa) series— which are typical rice growing soils under tropical savanna climate developed on local alluvium derived from limestone were sampled according to the genetic horizon and studied with the objectives to…
Zinc oxide is a unique material that exhibits semiconducting as well as piezoelectric properties. Oxidation of pure metallic zinc at low temperatures of 400-600 o C for 2 hours resulted in a variety of ZnO nanos tructures on the surface of metallic Zn. These nanostructures could have applica tions in a wide range of a…
Herein, we predict that graphene nanoribbons will be nonplanar under the influence of a critical perpendicular field. Our investigation demonstrates that the perpendicular field induces mixing of σ and π orbitals in graphene nanoribbons through the second order Stark effect which eventually modulates the electron-nucl…
Modeling of low-Capillary number segmented flows in microchannels is important for the design of microfluidic devices. We present numerical validations of microfluidic flow simulations using the volume-of-fluid (VOF) method as implemented in OpenFOAM. Two benchmark cases were investigated to ensure the reliability of…
A method has been developed to synthesise zinc oxide nanowire arrays that demonstrate superior device performance compared to conventional ZnO nanowires within dye sensitised solar cells (DSSCs). This simple yet effective methodology has produced nanowires with triple device performance when compared to conventional Z…
The tensile property of regenerated bamboo yarn of 14.58 tex was studied using an HD021N single yarn tensile tester at different tensile speeds (100, 500, 1000, 2000, 3000, 4000, and 5000 mm/min). It was observed that the distribution on diagrams of the breaking strengthfrequency and elongation at break frequency of y…
We have developed an efficient self-assembly strategy to readily achieve well-defined Au/TNTs heterostructure based on robust as well as multilayered dendritic dithiolated diethylenetriaminepentaacetic (DTDTPA) ligand as bridging medium. Versatile catalytic performances of the hybrid system were investigated.
