Geometrical optimization, spectroscopic analysis, electronic structure and nuclear magnetic resonance of 2‐amino‐3‐nitropyridine (ANP) were investigated by utilizing ab-initio (MP2) and DFT(B3LYP) using 6‐311++G(d,p) basis set. Geometrical parameters (bond lengths, bond angles and torsion angles) were computed and com…
We successfully developed a novel photocontrollable chromatographic system for separation of alkali metal ions. Based on the finding that the metal-ion complexation of spirobenzopyran derivatives bearing a crown ether moiety, which we call crowned spirobenzopyran, can be drastically changed by photoirradiation, crowne…
A novel technique for imaging the recombination current pre-factor Jo of heavily doped surface regions, ubiquitous to mainstream silicon solar cells, is introduced. This technique utilises photoluminescence in a low injection regime, allowing measurement of test structures with low and moderate resistivities, which ar…
A new organic single crystal of -Alanine Oxalate (BAO) has been grown from solution by slow evaporation technique. Transparent, colourless crystals of size upto 11 9 4 mm 3 were obtained. Formation of the new crystal has been confirmed by single crystal XRD and FTIR spectra. The grown crystals have been subjected to p…
The effects of SiCp addition on the z-value, microstructure and mechanical properties of β-Si6−zAlzOzN8−z–SiCp were investigated. The results showed that z-value of β-Sialon decreased from 2.66 to 1.20 with the increase of SiCp addition, while the apparent porosity of β-Sialon–SiCp composites increased. The bending st…
The solution model of Mn–Fe–Si–C system is essential in the development of high Mn containing steels and alloys, and its effectiveness depends on the well established information of constituting lower order systems. The solution property of Mn–Si system, which is one of such constituting binary systems, is not well es…
Hydrogen accumulation in samples of a palladium and 12Kh18N10T steel at the hydrogen charging by the electrolytic method and hydrogen release from these samples at its electron and X-ray irradiation are studied. Palladium was used as a comparison material (as most efficiently solvent hydrogen known among the simple ma…
In this paper the microwave plasma system for synthesis of carbon nanotubes is presented. The target of the system is the ability to produce carbon nanotubes in the form required to design a novel generation of electric and electronic devices. Slowa kluczowe: plazma mikrofalowa, nanorurki weglowe
Introduction: In apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. Mineral trioxide aggregate (MTA) is the gold standard material for this purpose. Changing water/powder ratios of MTA affects its properties. The purpose of this…
The interactions of ions and photons in ultraviolet (UV) and vacuum ultraviolet (VUV) regions from argon plasmas with polymer surfaces were investigated by of depth analysis of chemical bonding states in the nano-surface layer of poly(ethylene terephthalate) (PET) films via conventional X-ray photoelectron spectroscop…
Porous aromatic polyimide films of 28 and 59 μm thickness and with about 50% porosity (PAPIF-28 and -59) were carbonized and then heat-treated to various temperatures up to 3000 °C, and their texture and graphitizability were investigated. A porous texture on the micrometric scale remained on the surfaces and inside t…
有不同金属氧化物部件 RO (R=Ca， Sr， Ba， Zn 或 Pb ) 的做 Eu3+ 的二进制硼酸盐眼镜被融化熄灭技术准备。荧光灯光谱这些眼镜里的 Eu3+ 的性质试验性地被学习。声子边带(PSB ) 上的分析显示那个 RO 部件没引起联合常数(EPC ) 的电子声子的明显的变化。由检查光吸收，它被发现那 RO 的边能极大地影响乐队差距精力，并且有 PbO 部件的玻璃表明最小的乐队差距精力，有 ZnO 的眼镜， BaO 和 SrO 显示出类似的乐队差距精力。所有学习眼镜里的Eu3+的光转变紧张参数被计算，为每件样品，它 2 的价值比 4 和 6 的大，这被发现，并且有 PbO 部件的样品展出了最小 2 ，但是为 ZBE 的…
An economic analysis was performed on treatment options for pig manure in Ireland. Costs were based on a 500 sow integrated pig farm producing 10,500 m3 of manure per year at 4.8 % dry matter. The anaerobic digestion of pig manure and grass silage (1:1; volatile solids basis) was unviable under the proposed tariffs, w…
"The La0.5 Ba0.5 MnO3 (LBMO) polycrystalline compound was sintered by hydrothermal technique [1,2]. The precursors were dissolved in deionized water using potassium hydroxide (KOH) as mineralizer and taken to an environment of high pressure with a temperature of 240°C for 24 hours. The product is calcined in a furnace…
Silicon-on-insulator (SOI) nanowires with a single-layer graphene are fabricated and characterized. The propagation losses of TE- and TM- polarization modes are measured. Nonlinear absorption effect introduced by the graphene is also observed.
Polyamine dendrimer-encapsulated Pd 2+ catalysts were prepared by complexation of PdCl 2 with internal tertiary amino groups of the dendrimer.The fifth-generation Pd 2+ dendrimer catalyst showed cooperative catalysis between Pd 2+ species and the internal nanocavity consisting of regularly arranged tertiary amino grou…
Ferrous alloys using the TRIP and/or TWIP effect allow a combination of ultra-high strength and high ductility. The alloying concepts for theses steels are based on a manganese content between 12 a ...
"In the past couple of months, the quantum foundations world has been abuzz about a new preprint entitled "The Quantum State Cannot be Interpreted Statistically" by Matt Pusey, Jon Barrett and Terry Rudolph (henceforth known as PBR). Since I wrote a blog post explaining the result, I have been inundated with more corr…
Nearly monodisperse 17-20 nm ZnS nanoparticles capped with the Poly vinyl pyrrolidone (PVP) and Thioglycolic acid (TGA) were prepared in aqueous solution. During hydrothermal coarsening of ZnS nanoparticles, the evolution of optical properties and growth kinetics were investigated. As the particle size increased, the…
Compositional dependence of optical constants of thermally evaporated amorphous Se82-x BixTe18 (x = 0, 1.5, 2.5, 3.5 and 4.5 at %) thin films has been studied using well established Swanepoel method. The optical parameters like, refractive index (n), extinction coefficient (k), film thickness (d), absorption coefficie…
