In this research, we are analysing the behaviour of the wastes coconut shells of african palm (Elaeis guineensis) when dealing with different gas mixtures and its influence on the development of lattice porous internal and its formation as foam. The study shows that samples worked with water vapour mixtures developed the highest percentage of carbon foam as foams. The greatest expansion of the ...

The crystallization and melting behaviors of linear polylactic acid (PLA) treated by compressed CO(2) was investigated. The isothermal crystallization test indicated that while PLA exhibited very low crystallization kinetics under atmospheric pressure, CO(2) exposure significantly increased PLA's crystallization rate; a high crystallinity of 16.5% was achieved after CO(2) treatment for only 1 m...

Bone is a complex porous composite structure with specific characteristics such as viscoelasticity and anisotropy, both in morphology and mechanical properties. Bone defects are regularly filled with artificial tissue grafts, which should ideally have properties similar to those of natural bone. Open cell composite foams made of bioresorbable poly(L-lactic acid) (PLA) and ceramic fillers, hydro...

The present author treated tentatively the relation between the wind speeds in the wind wave scale 3 and the surface water temperatures in an open sea using the data of oceanographical observations taken at the Ocean Weather Station " X " (39°N, 153°E) in the North Pacific Ocean in view of the foaming of sea water, and the following results were obtained : 1) The general features of the frequen...

The Malassezia furfur fungal infection leads to dandruff formation. Dandruff cannot be fully eliminated but can only effectively controlled. This study intends formulate and evaluate the polyherbal anti-dandruff shampoo. prepared formulation not cleans dirt also makes hair soft lustrous promotes growth. eliminates use of harmful chemical ingredients that damages hair. uses various herbs like Ne...

Sustainability and eco-efficiency are presently directing the development of the next generation of acoustic materials. In this work, foamed cellulosepolymer microsphere (PM) hybrid materials, having sound-absorbing capability, were prepared by incorporating the PMs into cellulose fibers by dehydration and foaming processes. The evolution in morphology of PMs during foaming process was investig...

Absorption is one of the most established techniques to capture CO2 from natural gas and post-combustion processes. Nevertheless, absorption process frequently suffers various operational issues, including foaming. The main objective current work elucidate effect degradation product on foaming behavior in methyldiethanolamine (MDEA) piperazine (PZ) solution evaluate antifoaming performance poly...

Separation of various chemical components from each otheJO is often the most difficult step in analytical procedures. The problems attached to separation become further magnified when the species concentations are extremely low. A group of techniques that has proven useful especially in dilute solutions for separating and concentrating metallic as well as nonmetallic ions and complexes, protein...

The critical micelle concentration (cmc), the surface excess (Γ), as well as the micelle aggregation number (m) of the surfactant dodecyldimethylamine oxide (C12DMAO) have been reported to strongly depend on the pH-value of the aqueous surfactant solution. At high ionic strength, the cmc displays a minimum, while both Γ and m have a maximum at a pH-value close to the pKa of the surfactant. Thes...

The increase in the invertase activity of extracts from freshly cut potato (Solanum tuberosum L.) by "foaming," caused by selective denaturation of an endogenous invertase inhibitor, did not occur in extracts made from thin disks 2 days after slicing. Rather, foaming such extracts decreased invertase activity. Apparently, the inhibitor disappeared after slicing, and the enzyme became more labil...
