Under normal temperature and pressure conditions, potassium niobate nanowires with uniform diameter and good crystallinity were prepared by laser-induced method using KOH and Nb2O5 as raw materials. The samples were characterized by XRD, SEM, Raman and UV-Vis, the light absorption and photoluminescence properties of p…
Carbon nanotubes(CNTs) exhibit good mechanical, electrical and thermal properties, and thus with wide application prospects, therefore, attracted wide attention are received from scholars of various countries. CNT fibers and films, composed by CNT bundles, are the main application forms of CNTs in macroscopic scale. H…
The effect of twin types in compressed samples on nucleation of grains and texture evolution during static recrystallization was investigated by using electron backscattered diffraction analysis (EBSD). The cylindrical samples were compressed with a strain of 16% at room temperature, followed by annealing after holdin…
Ultrasonic impact treatment(UIT) was used for surface enhancement of 17CrNiMo6 steel. The effects of UIT time on the hardness, surface residual compressive stress and the surface structure refine ment were analyzed. Microstructure distribution of the structure refined layer was studied. The results show that, unproces…
Traditional electronic strain sensors based on metal and semiconductor materials have poor flexibility and wear-ability, which are not applicable for stretchable sensors. With the development of flexible electronic materials, wearable electronic devices show great market prospects. Flexible strain sensors have many un…
Optimization design of multifunctional machines for making of animal feed is one of the development efforts of conventional machinery to be a multifunctional machine with electric motor drive which is to help small MSME industries so that their results and capacity are faster and more effective during the process of m…
Metastability-based high entropy alloy design opens a new strategic path for designing high-strength materials. However, high strength is always coupled with poor damage tolerance under cyclic loading conditions (fatigue). To overcome this drawback, here we present grain-refined Fe42Mn28Cr15Co10Si5 exhibiting signific…
Most of our country is located in the earthquake zone where active fault lines exist. Statistical analysis show thatdamaging earthquake occurs every 8 months in our country.The major devastations due to the 1999 Kocaeli andDüzce earthquakes have caused almost impossible losses to compensate for the country's economy.…
In this study, the effects of Fly Ash (FA) and Ground Granulated Furnace Slag (GGBFS) on design of concretepavement are investigated. It has been observed how these mineral additives change the 7 days compressive strengthand splitting tensile strength of the concrete pavement, the 28 days compressive strength, splitti…
In this paper, the flexural performance of fiber-reinforced polymer (FRP) bars reinforced concrete (RC) beams after conditioning in a simulated seawater wet-dry cycling environment for 6, 9 and 12 months is experimentally investigated. Two types of FRP bars, i.e. basalt FRP (BFRP) bars and steel-FRP composite bars (SF…
In this paper, two different torque control approaches for PMA-driven (PMA = Pneumatic muscle actuator) revolute joints are presented and tested. In previous work controllers for PMA-driven robots are typically customized for the use on a specific robotic system. In contrast, the proposed controllers define a general…
Recently, calcined dolomite has been used as an anti-bacterial material in various applications for improving public health. Generally speaking, calcined dolomite exhibits anti-bacterial effects due to its strong alkalinity after hydration. There are authors who have reported that the calcined dolomite can generate Re…
This research concerned the standard value of surface roughness on Computer Numerical Control (CNC) to obtain fine pipe cutting result and is more useful for company to simply recognize the appropriate standard gap in designing. Standard design used is 30 mm with 3 specimen variations and variation gap value of 42 mm,…
The pump is a tool to provide the mechanical energy to the liquid in the pump constant fluid density and large. In terms of mechanism, the pump is divided into three types, namely, rotary pumps, pump the shaft/piston and centrifugal pumps. The use of the pump are the most widely used either in the household or in the…
Abstract Background The primary function of a suspension system is to isolate the vehicle body from road irregularities thus providing the ride comfort and to support the vehicle and provide stability. The suspension system has to perform conflicting requirements; hence, a passive suspension system is replaced by the…
La doped Bi2WO6 nanomaterials were synthesized by one step hydrothermal method using Bi(NO3)3·5H2O, Na2WO4·2H2O and La(NO3)3·6H2O as the raw materials. The phase composition and optical property of the as-prepared materials were systematically characterized by X-ray diffraction (XRD), UV-Vis diffuse reflectance spectr…
Mechanical behavior of 316L austenitic stainless steel with different pre-strains was studied at different temperatures of 293-573K and strain rates of 0.0005-0.01s-1, and the effect of pre-strain on mechanical behavior was investigated. The results show that yield strength of 316L stainless steel increases and elonga…
Galvanizing also denoted as zinc coating is a scientifically approved method applied to protect iron and steel against the effects of corrosion. In the galvanization process, aluminum is added with zinc. Zinc has numerous properties under different environmental conditions. These properties are subject to change when…
In the present work, multi-objective optimization of the input welding parameters influencing the quality of weld joint of AA 5052 H32 aluminium alloy by FSW process is investigated using response surface methodology and grey relational analysis. The quality of the welded joint is measured based on the higher value of…
Coarse-grained (CG) single-phase face-centered cubic (fcc) high-entropy alloys (HEAs) normally show insufficient room temperature strength. Here we design and implement a heterogeneous grain structure to strengthen a single-phase fcc Fe29Ni29Co28Cu7Ti7 HEA. Significantly, the heterostructured (HS) fcc HEA shows a dram…
