18. yüzyılın başından itibaren birçok gezgin ve araştırmacının ilgisini çekmiş olan Teos’taki Dionysos Kutsal Alanı’ndaki yapılar topluluğu 2010 yılından sürdürülen araştırmalarla ancak anlaşılabilmiştir. Hellenistik Dönem’in ünlü Mimarı Hermogenes’in eseri olduğu kabul edilen Tapınağı, yamuk biçimli temenos’u, temenos’u dört bir taraftan çevreleyen dor, ion dor-ion karışık düzenli stoa’ları, ç...

Andesite rock is commonly used as a heritage building in Southeast Asia, especially Indonesia. However, the study on consolidation of andesite still limited. This aimed to evaluate application effectiveness TEOS-based material type materials. TEOS was modular system with powder form mortar. andesite-TEOS mortar applied conservation techniques, for gap and joint filling. 
 successfully rock...

Partículas de sílica dopadas com o complexo quercetina-Al foram preparadas através da hidrólise e condensação do tetraetilortossilicato (TEOS) utilizando catálise ácida e básica. A catálise ácida resultou em partículas com diâmetro em torno de 200 nm. A catálise básica com TEOS foi executada sobre um sol de alumina dopado com quercetina utilizado como precursor caroço e com este procedimento fo...

Thin silica films were deposited on silicon wafers by the sol-gel technique, using spin coating. The sols were prepared by HC1 catalysis of tetraethylorthosilicate (TEOS) diluted in ethanol, using different molar ratios, R, of H20:TEOS. The films were then baked at various temperatures, and characterised using ellipsometry, profilometry, optical scattering and infrared spectroscopy. It was foun...

By finely tuning the TEOS/P123 molar ratio of the octane/water/P123/TEOS quadruple emulsion system and by controlling the synthesis conditions, an ultrafine emulsion system was isolated, under the confinement of which, nanoscale silica particles with ordered large mesopores (approximately 13 nm) have been successfully constructed; the obtained mesoporous silica particles have an unusual ultrafa...
