Ferromagnetic shape memory alloys (FSMAs), which are potential candidates for future technologies (i.e., actuators in robots), have been paid much attention their high work per volume and rapid response as external stimulation, such a magnetic field, is imposed. Among all the FSMAs, Ni–Mn–Ga-based were considered promising materials due to appropriate phase transformation temperatures ferromagn...

Mechanical characterizations of natural rubber filled with carbon-based nanomaterials were extensively studied in tensile and tear modes whereas fewer attempts have been conducted on a dynamic shear condition using double-bonded test piece. This is importance since rubbers are widely used as flexible membranes for wave energy harvesting devices. Therefore, this study was aimed to explore the mi...

In this study, the effect of ethylene on rheological and mechanical properties rubbers was investigated. For purpose, were produced by mixing EPDM containing in different ratios curing with sulfur. The formulations modified so that all samples had same hardness. Rheometer analysis results revealed flow consistency Suprene 512 F sample higher than other two samples. time 90% later As a result te...

Abstract: Rubber tree (Hevea brasiliensis) plantation is a major land use practiced in Xishuangbanna of south-western China. Effects of rubber plantation (RP) and tea-rubber intercropping (TRI) systems on soil organic carbon pools were evaluated by recording changes in soil organic carbon in an age sequence of 12-, 20-, 26-, and 40-year old plantations. Labile organic carbon (LOC) increased in ...

Natural rubber is produced by a rubber transferase (a cis-prenyltransferase). Rubber transferase uses allylic pyrophosphate to initiate the rubber molecule and isopentenyl pyrophosphate (IPP) to form the polymer. Rubber biosynthesis also requires a divalent metal cation. Understanding how molecular weight is regulated is important because high molecular weight is required for high quality rubbe...

This paper compares the alkali-activated fly ash (AAFA) manufactured with thermal oven curing and pulsed microwave curing methods. Fly ash activated by 8M NaOH solution at a liquid to solid ratio of 0.3 was cured by thermal oven at 85°C and domestic microwave oven, respectively. Apart from compressive strength test, the temperature profiles of AAFA samples were captured by thermal camera. React...

Concrete is an essential building material which is widely used in construction industry all over the world due to its compressible strength. Curing of concrete plays a vital role in durability and other performance necessities. Improper curing can affect the concrete performance and durability easily. When areas like scarcity of water, structures is not accessible by humans external curing can...
