The composites ((1 − x)(La0.6Ca0.4MnO3)/x(Sb2O3)) (x = 0.00, 0.07 and 0.12) were synthesized by conventional solid-state reaction method. The results of X-ray diffraction (XRD) and SEM indicate that Sb2O3 and LCMO coexist in the composites and Sb2O3 mainly segregates at the grain boundaries of LCMO. Furthermore, the m…
Through a coordinate transformation approach, crystal orientation dependences of elastic and piezoelectric properties at room temperature have been investigated in a three-dimensional space for rhombohedral bismuth ferrite (BiFeO3). Elastic constants (stiffnesses) c11′, c12′, c13′ and piezoelectric constants d15′, d31…
A fluorescence sensor for the detection of glutathione based on the fluorescence recovering of the bovine serum albumin-stabilized gold nanoclusters is reported. This study indicates that glutathione restores the copper-ion-quenched fluorescence by coordinating the bound copper ion in the bovine serum albumin molecule…

Carbon black (CB) is an electrical and reinforced material, which is used for many industrial applications; however, the serious aggregation of CB requires the addition of large amounts for the composites to meet the requirements of the antistatic properties. Multi‐walled carbon nanotubes (MWCNTs) are linear high elec…
Abstract Biological organisms exist in an astounding array of habitats. The materials produced by these organisms correspondingly exhibit significant diversity in function and form. Highly ordered and structured biological materials have been the subject of intense scientific investigation, especially in the context o…
The catalytic activity of metal nanoparticles can be altered by applying strain, which changes the crystalline lattice spacing and modifies the electronic properties of the metal. Understanding the role of elastic strain during catalytic reactions is thus crucial for catalyst design. Here, we show how single highly fa…
Solid Oxide Fuel Cell (SOFC) systems operating with methane usually are equipped with an external reformer to produce syngas. The conventional applied technology is steam methane reforming. Recent studies, instead, are presenting dry reforming as potential alternative. Advantages come from the substitution of steam wi…
Direct covalent connections of porphyrinoids have been demonstrated as an effective way to expand their π-electronic networks and perturb their optical and electrochemical properties. Covalent connections are also useful for studies on the precise electronic interaction between two porphyrinoid units. However, the che…
The dual-functionalized polyhedral oligomeric silsesquioxane (POSS) derivatives, which have the seven fluorinated alkanes and the single acrylate ester on the silica cube, were designed as a filler for lowering the refractive index (RI) and improving thermomechanical properties in poly(methyl methacrylate) (PMMA). The…
Complex dielectric and impedance spectroscopic studies have been carried out in a detailed manner on the system comprising of Bi2Fe4O9-BiFeO3 composite particles dispersed in a α-Fe2O3 matrix as prepared using ball milling and controlled annealing treatments. This multiferroic composite is observed to exhibit a giant…
, are presented. The aim of the experimental study was to compare the spectral data of both analytical techniques in terms of their sensitivity to chemical composition, isomorphic substitution of central atoms, and layer stacking order of the clay minerals. The results confirmed that Fourier Transform infrared spectro…
Abstract The detergency performance of α‐sulfo fatty‐methyl ester sulfonate (α‐MES) under different water hardness conditions was compared against the dominant workhorse in Home Care products, linear alkylbenzene sulfonate (LAS). Results demonstrate that α‐MES has a higher soil removal index and its detergency perform…

Laminated shells have been widely used as intelligent structures in many industries due to their unique characteristics of high strength/weight and stiffness/weight ratios. This paper presents a thermoelectromechanical analysis of multilayered one-dimensional piezoelectric quasicrystal cylindrical shells under surface…

This paper aims to report a sustainable novel green synthesis of MgO nanoparticles using leaves extracts of Calotropis gigantea. The average size of MgO nanoparticles obtained was 48.38 nm with the crystallite size of 8 nm. MgO nanoparticles were encapsulated by employing emulsion solvent evaporation. Nanoencapsulatio…

Reeves et al. in their recent work on small silicon quantum dots [ Reeves, Nano Lett., 2015, 15, 6429−6433] found that surface passivation with fluorine atoms results in a significant slow down of hot electron relaxation because there exist particular electronic states that retain the hot electron for an extended time…
