In this study mix proportion parameters of lightweight foamed concrete (LWFC) are analyzed by using the Taguchi’s experiment design methodology for optimal design. For that purpose, mixtures are designed in L16 orthogonal array with five factors, namely, Microwave Incinerated Rice Husk Ash (MIRHA) contents, water cementitious ratio (w/c), sand cement ratio (s/c), superplasticizier (SP) content,...

Hyaff 11 R , a material derived from hyaluronic acid with interesting applications as a scaffold for tissue engineering, is made porous by salt leaching and mechanically tested in simple tension and confined compression. The tests revealed a different behavior in tension and compression, a feature common to other foamed materials. The difference between the behavior in tension and compression i...

Biodegradable plastics are thought to be the possible directions in managing plastic pollutions. Unfortunately, they not recycled most countries since designed decompose even though recycling is a more pragmatic method than landfill or incineration. Thus, it constructive develop methods recycle biodegradable yet recyclable plastics. In this study, we used cutlery with composite of poly(lactic a...

The paper presents a numerical analysis of thick-walled PA66 GF30 moldings with the addition chemical blowing agent content 1-3 wt%, and obtained results were compared real object. Computer simulations performed using Moldex3D ® software. Based on analysis, it was found that regardless dose used, largest pores place in core sample. Moreover, size depends their number cross-section moldings. Com...

Polylactide (PLA)/wood flour composite foam were prepared through a batch foaming process. The effect of the chain extender on the crystallization behavior and dynamic rheological properties of the PLA/wood flour composites were investigated as well as the crystal structure and cell morphology of the composite foams. The incorporation of the chain extender enhanced the complex viscosity and sto...

The thermal degradation of foamed polymethyl methacrylate (PMMA) patterns in the expendable pattern casting process has been studied. Various physical transitions that may occur during the degradation of PMMA have been determined using scanning electron microscopy, differential scanning calorimetry, and thermogravimetric analysis, and the effects of polymer density on the degradation characteri...

Macrophomina phaseolina was cultivated in complex and simple media for the production of extracellular lipolytic enzymes. Culture supernatants were batch foam fractionated for the recovery of these enzymes, and column design and operation included the use of P 2 frit (porosity 40 to 100  μ m), air as sparging gas at variable flow rates, and Triton X-100 added at the beginning or gradually in al...
