The silicide hexaboride (B6Si) was irradiated with 60Co at room temperature to study the structural changes and weight kinetics. B6Si samples were using a gamma source dose rate (D) of 0.27 Gy/s. At adsorption range 9.7, 48.5, 97, 145.5 194 kGy. analysed X-ray diffraction (XRD) Energy dispersive spectroscopy (EDS) microstructural composition changes. XRD results showed crystalline structure for sample before after irradiation (with 48.5 97 kGy). Amorphization began Increase in had an inverse...
In this paper, high purity boron carbide samples were irradiated by [Formula: see text]Co gamma radioisotope source (0.27 Gy/s dose rate) with 50, 100, 150 and 200 irradiation hours at room-temperature. The unirradiated heated from 30[Formula: text]C to 1000[Formula: a heating rate of 5[Formula: text]C/min under the argon gas atmosphere flow 20 ml/min. Thermogravimetric (TG) Differential Scanning Calorimetry (DSC) carried out in order understand thermodynamic kinetics samples. weight...

In the presented work, a boron carbide sample with purity of 99.9%, particle size [Formula: see text]–[Formula: text]m and density text] was used. Boron samples were irradiated linear electrons in energy range 2.5 MeV at doses text], room temperature. XRD results show that only crystal structure compound, among dose rate from to phase transition does not occur. The observed decrease lattice parameter values explained as strengthening bonds result recombination defects by influencing electron...
CeO x -anchored β-Ni(OH) 2 nanosheets onto nickel foam electrodes have been developed for the efficient energy-saving hydrogen production via electrocatalytic glucose oxidation reaction.
Abstract The morphology and elemental compositions at the surface of poly(styrene sulfonic acid) (PSSA) grafted poly(ethylene‐co‐tetrafluoroethylene) polymer electrolyte membranes (ETFE‐PEMs) in a grafting degree (GD) range 0%–127% are investigated by using FE‐SEM XPS analyses. concentrations components not linear function GDs, resulting from different speeds bulk. In addition, low accumulation PSSA grafts on ETFE‐PEMs GDs 0%–19%, as well their homogeneous distribution through least GD 19%...
Mesopores and silanol nests are known two technological keys that essentially control the catalytic performance of ZSM-5 zeolite. However, designing controlling them without using chemicals so produced can have strongly enhanced properties more importantly be applied at industrial scale still been a big challenge up to now. The present study employed 10 MeV electron beam (EB) generated from an linear accelerator introduce both O-vacancy rich mesopores stable triad-silanol in ZSM-5....
Abstract The present paper reported on the analysis of structural defects and their influence red‐emitting γ‐Al 2 O 3 :Mn 4+ ,Mg 2+ nanowires using positron annihilation spectroscopy (PAS). were synthesized by hydrothermal method low‐temperature post‐treatment glucose as a reducing agent. X‐ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL), excitation (PLE) utilized, respectively, for determining phase, morphology intensity in studied samples.

Objective: Indocyanine green has been used in the assessment of gastric conduit perfusion thoracoscopic esophagectomy to prevent malperfusion-associated anastomotic leak. This study aims evaluate initial results investigating with indocyanine surgical treatment esophageal cancer. Patients and methods: cross-sectional descriptive was carried out on 54 cancer patients undergoing reconstruction. The blood flow observed using an infrared camera after completion tunneling through mediastinum...
Oxide dispersion strengthened (ODS) alloys are considered as candidates for fuel assembly claddings, since nano-oxides, among other things, contribute to the gas swelling suppression. However, it is still unknown that how oxides will behave in this capacity under exposure fission fragments. Transmission electron microscopy has been applied study helium porosity a ferritic EP450ODS alloy doped with by ion implantation and re-irradiated high energy Xe ions, which used simulating fragments at...
Due to the rapid scientific and technological development in last decades, basic research solid state physics, chemistry material science has focused on objects phenomena more confined dimensions time-scale, well visible for general publicity by introducing terms “nanophysics, nanoscience, nanomaterials, etc.”, often featured media. Researchers therefore keep searching better investigative techniques. Various nuclear analytical spectroscopies, such as Positron annihilation lifetime (PAL),...

This study investigated the chronology of heterogeneous, multilayered, and overlapped architectures by combining field experiments with computer simulations luminescence dating. The obtained results suggested that conventional homogeneous model was indistinguishable chronologies having structures could also result in virtual enhancements calculated from ten to several hundred years. In contrast, our proposed heterogeneous multilayered for both excavated buried status explicitly exhibited...
