Исследованы температурные и размерные зависимости изменения ширины запрещенной зоны квантовых точек CdSe с диаметрами 2.4, 4.0 и 5.2 нм во фторофосфатных стеклах. Показано, что для квантовых точек температурный коэффициент смещения ширины запрещенной зоны dEg/dT отличается от значения для объемного полупроводника и ст…
1. Introduction Halloysite is a dioctahedral 1:1 clay mineral of the kaolinite group frequently discussed in literature because of its potential for nanotechnological applications (Keeling, 2015; Yuan et al., 2015; Yuan et al., 2016). Its geological occurrence has been primarily linked to soil and weathering environme…
При температурах T=1.8, 4.2, 99-300 K изучены спектры ЭПР Gd3+ в монокристаллах CaMoO4. Определены зависимости параметров спинового гамильтониана bnm(T) (n=2, 4, m=0, 4) и проведен их анализ. Выделены температурные вклады статической решетки b2(L), b4m(L) в величины bnm(T). Для этого рассчитано изменение b2(L), b4m(L)…

We describe a means to produce thin layers of carbon, graphene multilayers, using laser etching followed by exfoliation. Complex macroscopic images can be produced in minutes. The laser need only mark the top-most layers of graphene for the image to become permanent down to the glass substrate. We use the technique to…
The impact of new evaluated nuclear data libraries (JENDL-4.0, ENDF/B-VII.0 and JEFF-3.1) on the core characteristics of small-sized long-life CANDLE High Temperature Gas-Cooled Reactors (HTGRs) with uranium and thorium fuel cycles was investigated. The most important parameters of the CANDLE core characteristics inve…
In this work, effect of vanadium doping of CaCu3Ti4O12 (CCTO) on microstructure and complex dielectric constant over wide frequency (100 Hz-1 MHz) and temperature (0°C – 160°C) ranges has been studied. The vanadium doping of CCTO system results in an increase of grain size, the grains being surrounded by melted-like g…

A self-assembled and packaged display medium is fabricated using microfluidic emulsion technology to encapsulated droplets of particles solutions in a curable continuous phase, which greatly simplifies the packaging process. After photo crosslinking, we obtain an emulsion droplet array of regularly and densely arrange…
ABSTRACT
В модели двух связанных осцилляторов рассмотрено смещение частоты рамановского пика G эпитаксиального графена вследствие взаимодействия с подложкой, описываемого эффективной силовой константой связи k. Показано, что относительный сдвиг G-пика Deltaomega(G)/omega(G) propto k/k0g, где k0g --- силовая константа центральн…
A signed graph is a graph where the edges are assigned either positive or negative signs. Net degree of a signed graph is the difference between the number of positive and negative edges incident with a vertex. It is said to be net-regular if all its vertices have the same net-degree. Laplacian energy of a signe…
This paper proposes the time domain parallel finite-element method (TDPFEM) coupling with equation of motion to efficiently obtain transient solutions of electric machines using parallel computing. The proposed TDPFEM is based on an iterative procedure combined with the Newton-Raphson iteration for a nonlinear magneti…
A method for measuring the Hall effect in the slow-temperature-drift mode is described. The proposed technique allows measurements of the electrical characteristics of semiconductor materials in a wide temperature range without the necessity to stabilize the sample temperature. This allows one to significantly increas…
Body shape analysis, as a key technology in the production of eMTM, plays a very important role in the production of eMTM. The results of shape analysis will directly influence the design of clothing prototype and the generation of garment pattern. Accurate body shape analysis is an important guaran
Приведены результаты исследования квазикристаллических покрытий, полученных при различных тепловых режимах напыления. Исходные квазикристаллические порошки были получены в плазме дугового разряда низкого давления и имели дисперсность 10-50 mum. Напыление покрытий проводилось на медные кольца качающимся плазмотроном.

A simple in situ solution process was developed to produce a mechanically and thermally stable ZnO-carbon nanotube fiber composite. ZnO nanoparticles were homogeneously deposited onto the surfaces of and interstices within CNT fibers (between individual CNTs). X-ray photoelectron spectroscopy and Raman analysis reveal…
