New Advances in Environmental Friendly Materials by Aloe Vera in Modern Approaches on Material Science in Lupine Publisher

This last decade has been characterized by the acquisition of new materials based on the biomass, with the objective of replacing the materials obtained from petroleum derivatives, due to the high costs, added to the fact that they are non-renewable inputs and as a measure of the preservation of the environment [1]. In all areas of study has been this responsibility of searching for new and versatile materials. Packaging, medical materials, agro-industry.

Corrosion of Snails in H₂CO₃ Medium and Their Protection by Aloe Vera in Modern Approaches on Material Science in Lupine Publishers

Snails are beautiful creation of nature. They occur in rivers as well as ponds. But these sources of water are contaminated by effluents, pollutants, acid rain, particulates, biological wastes etc. They can change the pH of water. Water is absorber of carbon dioxide and it converts carbon dioxide into carbonic. Other above-mentioned wastes also increase the concentration of H+ ions in water. They produce hostile environment for snails. The outer part of snails is made of CaCO3. It produces chemical reaction in acidic medium and corrosion reaction is accelerated thus deterioration starts on the surface of snails. This medium their survival becomes miserable.

Groups 4 and 15 and Organotin Condensation Polymers for The Treatment of Cancers and Viruses in Modern Approaches on Material Science in Lupine Publishers

 

This short review describes the use of group 4 metallocenes, group 15 organometallics and organotin polymers in the treatment of human cancer tumors and viruses. These metal-containing polymers show good inhibition of all the main group solid tumors including pancreatic, lung, brain, breast, prostate and colon human cell lines. They also show inhibition of a variety of viruses including zika, herpes and vaccinia viruses. Synthesis of the polymers is rapid employing interfacial polymerization and commercially available reactants. They offer physicians a new class of drugs for the treatment of a variety of cancers and viruses.

Palm Oil Fuel Ash as A Cement Replacement in Concrete by Jonida Pone in Modern Approaches On Material Science in Lupine Publishers

To produce concrete, cement is an essential material that binds together solid bodies but also is the largest producer of carbon dioxide (CO2) emission. Up to 10% of global CO2 emission comes from cement production thus making the sustainability of concrete a major issue that needs addressing. The processes of producing concrete consume heavily on natural resources such as sand, gravel, water, coal and crushed rock, mining of which damages the environment. It is however possible, that energy and cost efficiency can be achieved by reducing on the amount of clinker, and in its place utilizing partial cement replacements/pozzolans that require less process heating and emit fewer levels of carbon dioxide. This study investigates the effectiveness of agro waste ash by-product Palm Oil Fuel Ash (POFA) as an alternative material to replace Portland cement (OPC). Experiments were carried out by supplementing CEM I cement by weight in concrete mixes with POFA at 2.5%, 5%, 10%, 15% and 20% steps at the point of need, with water to cement ratio of 0.5. Results were compared with a control specimen, which was made with 100% cement. The results showed impressive compressive strength, especially at early age; in fact POFA specimens containing 2.5% and 5% POFA replacement displayed greater early compressive strength in comparison to the control, which is similar in behaviour to concrete containing silica fume which is an established partial cement replacement used in high strength applications. The results showed good repeatability and highlight the potential of POFA as an effective pozzolan which could enhance the sustainability and economic aspect of concrete.

New Materials: Current Development Under Simulation Techniques

By : Efrén Vázquez Silva*.

 

 

Abstract

In the present short communication, a point of view on the contemporary tendencies in the development of the Science of Materials is offered. And for this, the main lines of research (personal criteria) in this area are considered, linked to problems of great importance for humanity: the care and preservation of the environment, renewable sources of energy and the health of people.
