in this work, an optical sensor for detection of ascorbic acid is described. the sensor is fabricated by casting and spin-coating silica sol-gel doped with 2,6-dichlorophenol indophenol on the glass plates. the sols are in turn obtained by acidic hydrolysis of various precursors such as tetraethoxysilane, triethoxymethylsilane and triethoxyoctylsilane in the presence of 2,6-dichlorophenol indop...

Aloe vera gel has antibacterial properties. The content of compounds in aloe is saponins, anthraquinones, tannins, aloin, and acemannan. the potential as an edible coating for food products. Processing carried out goes through a heating process that does think to damage gel. This study aims determine activity formulated on S. aureus, mutans, E. coli K. pneumoniae bacteria. research method used ...

Implant-associated infections are notoriously difficult to treat and may even result in amputation and death. The first few days after surgery are the most critical time to prevent those infections, preferably through full eradication of the micro-organisms entering the body perioperatively. That is particularly important for patients with a compromised immune system such as orthopedic oncology...

The inherent reactivity of the Al–Cu alloys is such that their use for structural, marine, and aerospace components and structures would not be possible without prior application of a corrosion resistance system. Historically these corrosion resistance coatings were based on the use of chemicals containing Cr (VI) compounds. Silane coatings are of increasing interest in industry due to th...

Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...
