Abstract Solid‐state luminescence of organic dyes is an elusive frontier, and understanding and designing solid‐state stimuli‐responsive materials is not trivial. “Mechanoluminescence” (ML) or “triboluminescence” (TL), which is associated with fracture or force‐initiated luminescence from a material, is currently attr…
Chemical defects can progressively degrade the electronic structure of polymer dielectrics, ultimately leading to their failure. Because the polymer degradation and breakdown related processes are notably complicated in nature, they remain far from being understood both experimentally and computationally. Using a comb…
This book is both a review of current research and an undergraduate textbook for inorganic chemistry at university level. In university undergraduate lectures, basic concepts are mainly explained and added examples of frontier research are optional. However, in many cases, frontier research is more interesting for stu…
Abstract Enzyme mimics have broad applications in catalysis and can assist elucidation of the catalytic mechanism of natural enzymes. However, challenges arise from the design of catalytic sites, the selection of host molecules, and their integration into active three‐dimensional structures. Herein, we describe the de…
The effect of yttrium (Y) substitution at La-site on structural, microstructural and electrical transport properties of (La 0.7- x Y x )Ca 0.3 MnO 3 ( x = 0.00, 0.05, 0.10, 0.15 and 0.20) were investigated. Samples were prepared by conventional solid state reaction method and structural properties of the samples were…
The article is devoted to the analysis of changes in the magnetic characteristics of ferrites in the CoO-NiO-ZnO system by the simplex method. Ferrites of Ni-Zn, Co-Zn, and Co-Ni were synthesized in the form of nanoparticles (20-40 nm) using a new method for processing contact nonequilibrium low-temperature plasma (CN…
A series of biopolymer-based nanocomposite films were prepared by incorporating natural one-dimensional (1D) palygorskite (PAL) nanorods, and two-dimensional (2D) montmorillonite (MMT) nanoplatelets into sodium alginate (SA) film by a simple solution casting method. The effect of different dimensions of nanoclays on t…
ABSTRACT Shape memory properties of two thermoplastic multiblock copolymers composed of poly(lactic acid) (PLA) and poly(ethylene glycol) (PEG) having different PEG‐segment lengths of 6 and 11 kDa were studied. The performance as a shape memory polymer at high strain level (600%) and its interrelations with shape‐prog…
Abstract The direct synthesis of nanostructured electrode materials on three‐dimensional substrates is important for their practical application in electrochemical cells without requiring the use of organic additives or binders. In this study, we present a simple two‐step process to synthesize a stable core–shell stru…
This chapter focuses on the surface properties of diamond, and on the structure and chemistry of individual crystal faces. A great deal has been learned about the structure and reactivity of diamond surfaces, which are analogous in many ways to both silicon surfaces and organic molecules. Experimental studies of the s…
This chapter begins with a discussion of the gaseous chemistry of both the hydrogen and relevant hydrocarbon species, followed by an examination of the evidence regarding which hydrocarbon species contribute to diamond growth. It discusses the diamond growth chemistry, with relevant experimental observations, and a di…
An efficient transmission line model in the micrometric order is presented in this paper, to determine the thickness of thin dielectric films deposited on highly-doped substrates. In particular, the estimation of the thickness is based on multiple reflections of an incident infrared electromagnetic wave generating int…

Сталь після швидкісного нагрівання до 820°C охолоджували з різними швидкост…
“Click” chemistry, used to promote nanoparticle assemblies, is a powerful strategy which has emerged very recently to control the spatial arrangement of nanoparticles onto surfaces. Such a strategy may be of high interest for applications such as magnetic recording media or magnetic sensors which are based on the fine…
Anodization of some valve metals such as titanium (Ti), leads to the self-organized nanostructured. In this work we present a systematic study of the formation, characterization, and refractive index of titanium dioxide (TiO 2 ) nanotubes. The anodizing of Ti foil was performed in ethanol-H 2 O electrolyte (50%) mixtu…
High Resolution Image Download MS PowerPoint Slide Tm 3+, Er 3+ -doped and -co-doped α-NaYbF 4 nanoparticles were synthesized via a facile hydrothermal route with oleic acid as the capping agent. Experimental results showed that the doped NaYbF 4 nanoparticles possessed a cubic phase with the average size of ∼13 nm. U…
The nanostructures with uniform long-range ordered structure are of crucial importance for performance standardization of high-quality surface-enhanced Raman scattering (SERS) spectra. In this paper, we described the fabrication and SERS properties of Au decorated Cu (Au@Cu) nanoarrays. The Cu nanoarrays with uniform…
Graphene has been considered one of the most important materials for many applications due to its unique electronic structure, physical and chemical properties. Graphite flakes are the main source of graphene oxide which can be transformed to graphene after reduction. The effect of irradiation on graphene oxide has be…
Strain gauges and optical methods are commonly used to measure the magnetostriction coefficient of a sample. All these methods require a specific size sample and can only realize offline measurement, which is time-consuming. Therefore, we propose a new method using a magnetostriction-based electromagnetic acoustic tra…
