In the uranium enrichment plants of the South African Nuclear Energy Corporation SOC Ltd (Necsa), sintered polytetrafluoroethylene (PTFE) filters were used to remove gas entrained solid particles, in order to prevent blocking of the isotope separating elements. When these plants were decommissioned and dismantled, the…
This is a modification of the origianl Chelex 100 extraction described by Walsh, Metzger and Higuchi (1991 BioTechniques 10(4):506). Adding PVPP facilitates working with environmental samples as well as pure cultures hi in phenolics or other contaminants.
Dentre os processos de fabricacao, a usinagem ganhou destaque principalmente com as inovacoes tecnologicas aplicadas a esse setor, especialmente, com objetivo de aumentar a vida da ferramenta. As aplicacoes em revestimentos para as ferramentas de corte tem contribuido para esse ganho, alem de proporcionar o aumento de…
Spargers are porous devices used for the continuous injection of gas bubbles into liquids. They have many applications like effective aeration in bio reactors, enhanced oil recovery, flotation, filtration and water treatment. In this study low cost spargers are fabricated, utilizing a new method. Nano- and microstruct…
As fossil fuels are quickly depleting, there is a search for alternative energy resources such as solar energy. An advantage of the Dye Sensitized Solar Cells (DSSC) with respect to competing technologies, is that its performance is remarkably insensitive to temperature change and incident angle of solar light. Thus,…
Bu çalışmada hidroksietil seliloz (HEC) polimerinin yapısal ve termal özellikleri üzerine Na-Montmorillonit (NaMMT) yada Sepiolit (Sp) kil ilavelerinin etkilerini inceleyebilmek için kil-polimer nanokompozitleri hazırlanmıştır. Polimerik filmler HEC polimerinin sulu çözeltisi ile killerin sulu dispersiyonlarının birle…
Squeeze Casting merupakan salah satu metode pengecoran logam dimana proses logam cair mengalami solidifikasi dibawah tekanan yang tinggi. Proses penekanan untuk memadatkan logam cair dilakukan di dalam cetakan yang ditekan dengan menggunakan hidrolis. Penekanan logam cair pada permukaan cetakan dapat menghasilkan penu…
The structural and magnetic properties of Ni nanowires (NWs) electrodeposited in anodic aluminum oxide (AAO) membranes with diameters in the range from 35 to 75 nm and an interpore distance of 105 nm have been investigated. The expected interplay between the shape anisotropy and the dipole-dipole interactions between…

Sensor technologies have become crucial in improving health and environment by continuous monitoring of toxic chemicals, hazardous pollutants like benzene or ions that are threats to environmental safety. Air and water pollution is a major global issues leading to mortality of millions of people all around the world.…
Ice-templating is an emerging and versatile technique that can be employed to synthesize advanced macroporous ceramics and multilayered ceramic-polymer composites for various engineering endeavors. In ice-templating of ceramics, typically an aqueous ceramic suspension is unidirectionally frozen that results in the for…
La defaillance des materiaux et structures d'ingenierie peut etre considere comme le resultat d'une interaction complexe entre differents phenomenes physiques tels que la nucleation des cavites, les microfissures, les microvides et d'autres processus irreversibles. Ces micro-defauts se fondent eventuellement en une ou…
Biocompositos de matriz de polimero biodegradavel com 10% em massa de fibras vegetais de curaua foram processados em duas etapas: a primeira consistiu em uma pre-mistura via moldagem por compressao ou em um misturador termocinetico para a manufatura de masterbatches e a segunda etapa via moldagem por injecao. Os bioco…
Two welding schemes of single and double pulse were used for the resistance spot welding of DP1000 dual phase steel. The changes in the mechanical performance and variant pairing of martensite under two different welding conditions were scrutinized. It is demonstrated that, although both welds fail in pull-out failure…
