Based on the properties, structure and application of dendritic polymer, this paper analysed the methods of the preparation of nanoparticles using dendritic polymer, detailed preparation process, technical parameters and application effect about a single metal nanoparticles, bimetallic nanoparticles, sulfide and halid…
In this work, mullite-zirconia composite were fabricated by reaction sintering of Algerian halloysite Al2Si2O5(OH)4, boehmite Al(OOH), and zirconia (ZrO2) powder using conventional heating. The appropriate amount of the three raw powders was ball milled for 5 h and sintered between 1250 and 1650 C for 2 h. A scanning…
Silk protein fibers produced by silkworms and spiders are renowned for their unparalleled mechanical strength and extensibility as natural materials. We demonstrate the ability to finely control the structure of silk proteins (both naturally derived and genetically engineered) at the nanoscale. This fine control is ob…
Nanofibrillär cellulosa (NFC) skum är en intressant klass av cellulära material med möjliga applikationer som sträcker sig från fordonsindustrin till biomedicin då det har unika och önskvärda mekaniska egenskaper. I ljuset av de senaste framstegen inom framställning av skum förutspås det tillämpas inom en rad olika om…
The ABS/PET and ITTR/ABS/PET alloys were prepared by melt blending method using hard-shell structure of isocyanate terminated silicone resin as compatibilizer. Moleculestructure of ITTR, PET and the alloys had been characterized by FTIR and mechanical properties such as impact strength, bending strength had also been…
One of the most promising contenders in the race for efficient, cost-effective solar materials is the perovskite solar cell. The solar-cell devices in this work consist of an etched glass substrate coated with indium tin oxide, a nickel oxide layer, a hybrid organic-inorganic perovskite layer, a zinc oxide layer, and…
This PhD thesis aimed at developing a new superlight Mg-Li-Ca alloy with superior properties. Binary Mg-30Ca and Mg-14Li (wt %) master alloys were melted successively in the induction furnace to obtain a Mg-Li-Ca ternary alloy containing 3.99 % Li and 1 % Ca. The alloy is designated Mg-4Li-1Ca (LX41). The as-cast mate…
Titanium and titanium alloys, due to their higher cost are seldom used for varied applications, unlike aluminium, magnesium and steel, which are widely used. Powder metallurgical route has given a new dimension to produce low-cost, near-net shaped parts using titanium powders. The conventional method of producing tita…
Chemical reaction dynamics on the oxide formation at the Ni(001) surface has been studied via two quantum beams (synchrotron radiation and supersonic molecular beam). It was revealed that NiO layers formation took place at an oxygen coverage less than 0.5 ML depending on translational energy of oxygen molecules. Altho…
A preliminary design study of GFR with helium gas-cooled has been performed. In this study used natural uranium and plutonium results LWR waste as fuel. Fuel with a small percentage of plutonium are arranged on the inside of the core area, and the fuel with a greater percentage set on the outside of the core area. The…

The method of growing thin films PLD, is widely used in applications and possesses great potential in thin YBa 2 Cu 3 O 7-δ films production with outstanding physical properties. However, it is limited in nano and micro technology due to the presence of particles on the surface of the films. This article describes som…
Large research facilities are major research enablers for expanding fields in various natural sciences. Traditionally built for physics and astronomy, nowadays fields like life sciences, medicine, molecular sciences and material sciences have become the driving forces, especially for particle accelerator based researc…
Density functional theory calculations are performed to study the electronic and optical properties of methylammonium lead/tin iodide perovskites under hydrostatic strain. It is found that the bandgap is significantly reduced to only 80/14 meV in lead/tin iodide perovskites under a moderate −6%/−4% strain. Such bandga…
Показано, что испарение капли воды диаметром ~ 1 mm под воздействием лазерного излучения с длиной волны 10.6 mum и потоком мощности (4-12)· 105 W/m2 обусловлено оптическими свойствами регулярных неровностей, имеющих место на поверхности капли. DOI: 10.21883/PJTF.2017.06.44397.16207
The aim of the paper is to control residual deformation of the handbrake arm assembly under lateral force in an effective way. Compared with the test method, nonlinear FEA method is higher in accuracy and fewer in cost of test specimen, which is an available means to control the residual deformation before producing.
Self-assembled silver nanowires were applied to SERS-detectable and ordered-substrate-induced cellular growth to understand the stretched bimolecular behaviour.
One of the biggest challenges in manufacturing automotive lithium-ion batteries is to achieve consistent weld quality in joining multiple layers of dissimilar materials. Although most fusion welding processes face difficulties in such joining, ultrasonic welding overcomes those difficulties due to its solid-state proc…
For the control and adjustment of the infiltration quality of the magnesium alloy liquid in porous perform, the coupling effect of temperature and pressure should be considered simultaneously. The thermodynamic characteristics of the local region can be adjusted by changing the boundary temperature of the porous perfo…
