The microstructural evolution of 300M steel during the isothermal treatment between deformations is studied. Firstly, interrupt compressions of 300M steel at temperature of 1273K and strain rate of 0.01s-1 are conducted to figure out the kinetics of static recrystallization (SRX) and meta-dynamic recrystallization (MD…
The article gives an approach to a solution of the problem of improvement the avionic equipment vibration resistance. It is shown that the use of the tests, which are provided by the state standards do not insure the required level of the failures caused by mechanical damages. Due to the fact that the tests are carrie…
A series of Ni1-xCuxFe2O4 (0.0 ≤ x ≤ 1.0) nanofibers have been synthesized employing electrospinning method at 650°C. The effect of Cu substitution on structural, morphology and magnetic properties of NiFe2O4 nanofibers is reported. The XRD analysis showed the formation of single-phase cubic spinel Ni-Cu ferrite and a…
This study aims to determine how natural silk business development in the village Solie Soppeng Regency through the implementation of agribusiness and the extent of natural silk farmers' income systems. This research used a qualitative approach. The results showed that natural silk business in Soppeng supported with c…
Well-dispersed alumina ceramic-graphene oxide (GO) powder mixtures were fabricated using a colloidal processing route and three drying techniques were applied: in vacuum, spray and freeze dryers. Dense composites were obtained via spark plasma sintering, the technique reducing GO to graphene in situ during the sinteri…
Contactless pressure monitoring based on Förster resonance energy transfer between donor–acceptors pairs immobilized within a thermoplastic elastomer is demonstrated for novel stretchable opto-electronics and opto-mechanical sensors.
Electronic equipment’s are manufactured with many types of Electronic components which are largely available as leaded and leadless mounting, these components are mounted on the PCB with through-hole or surface mounted technologies. The electronic equipment’s which are used in aerospace, space, military, commercial ap…
A unique molecularly thin nanocellulose (MT nanocellulose) structure –obtained by 2,2,6,6-tetramethylpiperidin- 1 oxyl (TEMPO)-oxidation and sonication– was examined by TEM and solid-state 13 C NMR to advance the current understanding on the supramolecular structure of cellulose I microfibrils. The width distribution…
The technology develops rapidly. It may cause the advantages or disadvantages in every things. The effect can also in fashion industry. In Indonesia or another country, fashion industries had rose rapidly, such as garment industries which produce men's, women's and children apparels in big quantity. Fashion Industries…
Thermoforming allows the manufacture of structural parts for the automotive and aeronautical domains using long fiber thermoplastic prepregs with short cycle times. During this operation, several sheets of molten prepregs are stacked and subjected to large macroscale strains, mainly via in-plane shear, out-of-plane co…

Создан фоторезистивный детектор циркулярно-поляризованного излучения на основе структуры металл--диэлектрик--полупроводник CoPt/(Al2O3/SiO2/Al2O3)/InGaAs/GaAs. Эффективность детектирования циркулярно-поляризованного излучения составляет 0.75% при комнатной температуре. Работа детектора основана на проявлении эффекта м…
The main objective of the presented work is to evaluate the compression behavior of a polymeric foam blend by using a robust framework for the testing sequence of foaming injection molded parts, with the aim of establishing a standard testing cycle for the evaluation of new matrix material. The research purpose is to…
To modify the properties of polyamide 6 (PA6), trimethylolpropane tris[poly(propylene glycol), amine terminated] ether (PEA) was added to PA6 matrix by melt-mixing. By FTIR, 1H-NMR, DSC, melt index, relative viscosityand mechanical properties measurements, it was found that PA6/PEA blends have excellent melt-flowabili…
In this work, we studied on the mechanical behavior of RB-SiC by the indentation experiments. The Vickers hardness tester and the laser scanning confocal microscope are used to process and observe the RB-SiC sample pieces. The indentations result shows that the hardness at the Si phase is lower than the SiC phase, thu…
Polypeptides and engineered proteins are a class of bioinspired and biomedical materials. Polypeptides like elastin-like polypeptides, collagen polypeptides and silk polypeptides are a kind of biopolymers that are biocompatible and biodegradable, which are widely used in biomedicine ranging from drug delivery to tissu…
Plasmonic hot spots, capable of confining strong electromagnetic fields near metallic surfaces, are particularly essential to a variety of enhanced spectroscopic techniques.
The (C 3 H 6 N 6 ) 0.67 V 2 O 5 hybrid nanorods are synthesized through the self-assembly of melamine organic molecules confined by V 2 O 5 layers and used as cathode material in the lithium-ion battery. The prepared hybrid overcomes the irreversible structure puckering problem of Li x V 2 O 5 when excess Li + , x > 1…
We have investigated the accuracy with which the effective atomic number (Z eff ) of an alloy can be measured using the intensity of the thick-target bremsstrahlung produced by low-energy electrons incident on the alloy target. The experiments involved 5 keV-electron beams incident on thick brass, Ni/Fe/Mo, C-276, and…
This study aims at proposing the mix proportions of low energy super-sulfated cement (SSC) concrete from industrial waste anhydrite from circulating fluidized bed combustion (CFBC) fly ash (CFA) as an alternative sulfate activator of ground granulated blast furnace slag (GGBFS/slag). The optimized mix proportion of th…
