Abstract We investigate the performance of a charged-particle detector fabricated using single-crystal diamond grown by chemical vapor deposition. The detector identified four different 241Am α-particle energies (5.389, 5.443, 5.486, and 5.545 MeV) thanks to its superior energy resolution of 0.407 ± 0.004% for electro…
Hybrid nanoparticle (NP) structures containing organic building units such as polymers, peptides, DNA and proteins have great potential in biosensor and electronic applications. The nearly free modification of the polymer chain, the variation of the protein and DNA sequence and the implementation of functional moietie…
We modified JASMINE code, a fuel–coolant interaction simulation code developed at Japan Atomic Energy Agency (JAEA), to extend the applicability for ex-vessel melt coolability assessment. The modification included addition of a melt particle size distribution model based on an empirical correlation and a simple non-lo…
Purpose – This paper aims to discuss how acrylic resin influences the smoke generation of intumescent flame retardant coatings. Design/methodology/approach – Thermal decomposition kinetics is used in this study to simulate the burning process. The thermal decomposition of acrylic resin can be identified in the intumes…
Purpose – The purpose of this paper is to investigate the film formation mechanism of zirconium-based conversion layer on mild steel. In this way, different approaches were used to show the self-limiting film formation mechanism. Design/methodology/approach – To determine this mechanism, film formation was detected us…
The fluctuations in the conductance of graphene that arise from a long-range disorder potential induced by random impurities are investigated with an atomic tight-binding lattice. The screened impurities lead to a slow variation of the background potential and this varies the overall potential landscape as the Fermi e…
The nanoscale research advances meant for application in medical sciences has seen a prominent participation of experts from different fields. The leading explorations has brought about new methods, techniques, technologies and drug formulations that find applications in different specialties of medical science. The n…
Second harmonic generation (SHG) and the first hyperpolarizability (βijk) of two novel quaternary diamond-like semiconductors, Li2CdGeS4 and Li2CdSnS4, are investigated based on the band structure calculations. Calculations show that these materials possess wide and direct energy gaps of about 3.10 eV (Li2CdGeS4) and…
The iron selenide compound Ba2F2Fe(1.5)Se3 was synthesized by a high-temperature ceramic method. The single-crystal X-ray structure determination revealed a layered-like structure built on [Ba2F2](2+) layers of the fluorite type and iron selenide layers [Fe(1.5)Se3](2-). These [Fe1.5Se3](2-) layers contain iron in two…
The plastic properties of an aluminium alloy are defined by its microstructure. The most important factors are the presence of alloying elements in the form of solid solution and precipitates of various sizes, and the crystallographic texture. A nanoscale model that predicts the work-hardening curves of 6xxx aluminium…
Atomic laminates such as MAX phases benefit from the addition of oxygen in many ways, from the formation of a protective oxide surface layer with self-healing capabilities when cracks form to the tuning of anisotropic conductivity. In this paper oxygen incorporation and vacancy formation in M 2AlC (M = Ti, V, Cr) MAX…
In this work, synthesis and chemical modification of a polystyrene‐block‐polyisoprene (PS‐b‐PI) diblock copolymer is presented. The modification reactions result in hydroxyl, amine, and carboxyl end‐functional groups, respectively. Thermal analysis reveals a shift of the glass transition temperature of the polystyrene…
In this randomized, double-blind, placebo controlled clinical trial, the effects of Dendropanax morbifera (D. morbifera) Léveille on heavy metal (cadmium and mercury) excretion as well as on lipid peroxidation and Cu, Zn-superoxide dismutase (SOD1) activity were investigated. For this study, tablets containing placebo…
Low-cost grain oriented silicon steel produced by continuous annealing, low slab-heating temperature, and omitting normalization annealing is explored and analyzed. This type of grain oriented steel is designed to replace the non-oriented steels used for the production of transformers of medium and small sizes as spec…
An efficient phonovoltaic (pV) material requires a highly energetic optical phonon $({E}_{p,\mathrm{O}}\ensuremath{\gg}{k}_{\mathrm{B}}T)$ with linewidth dominated by the electron-phonon (e-p) coupling and resonant with its electronic band gap $(\mathrm{\ensuremath{\Delta}}{E}_{e,g})$, as discussed in Paper I [C. Meln…
Energy and power capability of a supercapacitor is important because of its function to provide backup power or pulse current in electronic/electric products or systems. The choice of its electrode materials, typically such as carbon, metal oxide or conducting polymer determines the mechanism of its energy storage pro…
Combining mechanical properties with enhanced cell interaction is highly desirable in a biomaterial. In this study, a new paradigm for enhancing the mechanical properties of segmented polyurethanes (SPUs) through solution blending with a biopolymer is presented. This noncovalent approach is based on the premise that m…
A study of post-refinement absolute structure determination using previously published data was carried out using the CRYSTALS software package. We show that absolute structure determination may be carried out optimally using the analyses available in CRYSTALS, and that it is not necessary to have the separate procedu…

Design/methodology/approach This paper recognizes the SMF region and constructs a binary feature matrix according t…
Hydrogen atom adsorption on high-quality graphene on Ir(111) [gr/Ir(111)] is investigated using high-resolution electron energy loss spectroscopy. The evolution of the vibrational spectrum, up to 400 meV, of gr/Ir(111) upon increasing hydrogen atom exposures is measured. The two dominant binding configurations of atom…
