Structures, Morphological Control, and Antibacterial Performance of Ag/TiO2 Micro‐Nanocomposite Materials

Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
Structures, morphological control, and antibacterial activity of silver‐titanium dioxide (Ag/TiO2) micro‐nanocomposite materials against Staphylococcus aureus are investigated in this study. Horizontal vapor phase growth (HVPG) technique was used to synthesize the Ag/TiO2 micro‐nanomaterials, with parameters of growth temperature and baking time.

Improved Design of Anaerobic Digesters for Household Biogas Production in Indonesia: One Cow, One Digester, and One Hour of Cooking per Day

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
A government‐sponsored initiative in Indonesia to design and implement low‐cost anaerobic digestion systems resulted in 21 full‐scale systems with the aim to satisfy the cooking fuel demands of rural households owning at least one cow. The full‐scale design consisted of a 0.3 m diameter PVC pipe, which was operated as a conventional plug‐flow system ...

Effect of Clay Addition on Mechanical Properties of Unsaturated Polyester/Glass Fiber Composites

International Journal of Polymer Science, Volume 2013, Issue 1, 2013., 2013
Unsaturated polyester (UP)/glass fiber/clay composites were prepared by hand layup method. The effect of clay loading on the morphological and mechanical properties of UP/glass fiber composites was investigated in this study. X‐ray diffraction (XRD) was used to characterize the structure of the composites.

Image‐Processing‐Based Study of the Interfacial Behavior of the Countercurrent Gas‐Liquid Two‐Phase Flow in a Hot Leg of a PWR

Science and Technology of Nuclear Installations, Volume 2012, Issue 1, 2012., 2012
The interfacial behavior during countercurrent two‐phase flow of air‐water and steam‐water in a model of a PWR hot leg was studied quantitatively using digital image processing of a subsequent recorded video images of the experimental series obtained from the TOPFLOW facility, Helmholtz-Zentrum Dresden-Rossendorf e.V. (HZDR), Dresden, Germany.

Counter Current Flow Limitation of Gas‐Liquid Two‐Phase Flow in Nearly Horizontal Pipe

Science and Technology of Nuclear Installations, Volume 2012, Issue 1, 2012., 2012
Experimental work about counter current two‐phase flow of air and gas in nearly horizontal pipe has been performed. The work was performed in a 1.1 m long circular transparent acrylic pipe with 50 mm inner diameter, in two inclination angle settings (20° and 10° from horizontal). The smooth liquid and air inlet was used.
