Abstract In this study, the gradient grain induced by punching deformation and recovery treatment on a cupronickel alloy surface sample were investigated, and their effects on corrosion resistance were measured by atom force microscopy (AFM), X‐ray diffraction (XRD), electrochemical measurement, electron work function…
Metal sulfides-based nanomaterials have been used as a class of efficient solar driven photocatalysts. However, the H2-production rate observed over these photocatalysts remains problematic. Here, the AgInS2-xAg2S-yZnS-zIn6S7 (x, y, z = 0 or 1) nanocomposites with controlled compositions have been successfully prepare…

Colloidal gels are defined as systems that, to exhibit solid-like properties, must fulfill both conditions, local arrest of the particles and formation of space spanning networks. This chapter highlights the essential components and properties of colloidal gelation. It focuses on three key concepts related to colloida…
Porous fibers are advantageous for filtration systems, drug delivery systems, and in the field of tissue engineering, in comparison to their non-porous counterparts. In this study, we developed a facile technique including two steps to generate poly(3-hydroxybutyrate-co-3- hydroxyvalerate) (PHBV) porous fibers with a…
Because of high surface-to-volume ratio, few layers MoS2 material as a kind of 2D materials has been attracted more attention nowadays to be used for photonics devices. We investigated the performance of few-layer MoS2 when it is covered on a side polished fiber (SPF) to sense relative humidity (RH) of environments. T…
Symplocos paniculata is a medicinal plant used by native healers to manage gastrointestinal ailments. The crude methanolic extract of S. paniculata was screened pharmacologically both in vitro and in vivo for the validation of its therapeutic potential. It suppressed the spontaneous activity of isolated rabbit jejunum…
Optical and electrical properties (Haze spectra, carrier concentration, mobility, resistivity) of zinc oxide thin films deposited on glass substrates were studied by plasma treatment and by thermal annealing. Films of copper oxides on the glass and CuO/ZnO structures were formed by vacuum deposition of copper films fo…
ABSTRACT The incorporation of carbon nanofiber (CNF) into glass fiber (GF) composites is a potential route to extend polymer composite service‐life and enhance mechanical properties. Under nonstatic conditions, only limited information concerning water uptake and contaminant release properties of nanocomposite materia…
Stochastic foam models are generated from Voronoi spatial partitioning, using the centers of equi-sized hard spheres in random periodic distributions as seed points. Models with different levels of polydispersity are generated by varying the packing of the spheres. Subsequent relaxation is then performed with the Surf…
A simple method of preparing stimuli‐responsive polystyrene (PS)/polycaprolactone (PCL) nanolayered films with by growing poly(N‐isopropylacrylamide) (PNIPAM) brush on the surface by surface‐initiated polymerization is reported. Atom transfer radical polymerization (ATRP) initiator with a benzophenone moiety is attach…
Austempered bainitic ductile iron has been widely used in machinery components and parts due to its low fabrication cost, excellent mechanical properties, and abrasive wear resistance. In order to get a fine bainitic matrix, austempering process is usually adopted which consists of austenitizing temperature, austemper…
Abstract Soluble metal‐hydroxide clusters of Group 13 metals are popular in both materials chemistry and geochemistry. In geochemistry these clusters are used as experimental models for clay‐like minerals. In materials chemistry these clusters are the precursors for useful thin films. However, little is known about th…
By finding a way to reduce decoherence in relatively dense collections of tiny molecular magnets, researchers have renewed interest in such quantum systems.
Differential scanning calorimetry was used to study enthalpy relaxation kinetics of the Ge20Te(80-y)Sey infrared chalcogenide glasses for the compositional range y = 0–8. The relaxation behaviour was described in terms of the phenomenological Tool–Narayanaswamy–Moynihan (TNM) model. The direct curve-fitting procedure…
After more than 20 years of research on rear side gratings for light trapping in solar cells, we have been able to demonstrate enhanced efficiencies for crystalline silicon solar cells with two different grating concepts and solar cell architectures. In both cases planar front sides have been used. With hexagonal sphe…
Abstract A novel isohedral 3‐periodic net (i.e. a net with one kind of tile), showing a Cairo pentagonal tiling projection on the Euclidean plane, has been identified in a series of site‐modified CuCN/CuSCN networks, namely, [Cu6(SCN)2(CN)6⋅Ni(tpy)2]n (1), [Cu6(SCN)(CN)7⋅Ni(tpy)2]n (2) and [Cu6(CN)8⋅Ni(tpy)2]n (3) (tp…
Hollow gold nanostructures (HGNS) have been used in variety of optical biosensors due to their inherent advantage of operating at near infra red (NIR) wavelength, large extinction coefficient and high dielectric sensitivity. The absorption wavelength of these nanostructures can be modulated by changing the ratio of ho…
Degradation and mineralization of aqueous methylene blue (MB) are investigated in a bench scale external loop airlift sonophotoreactor. A central composite design along with response surface methodology is employed to model and optimize the sonophotolytic process. A quadratic empirical expression between responses and…
