RESPUESTA FOTOCATALITICA DE NANOPOLVOS DE TiO2 DOPADOS CON Ce Y La EN LA DEGR...amauri rincon lopez
Uso de fotocatalizadores de TiO2 para el tratamiento de agua contaminada.
El dióxido de titanio (TiO2) es un semiconductor empleado como fotocatalizador debido a sus propiedades, las cuales varían según su estructura cristalina (anatasa, rutilo, brookita y TiO2 (B)), siendo las fases anatasa y rutilo las más activas. El principal inconveniente del TiO2 es su elevado valor de banda prohibida (3.2 eV), que ese encuentra en el espectro UV y solo absorbe el 5% de la radiación solar. En este trabajo, los compuestos de TiO2 dopados con Ce y La con una relación molar de 1, 3 y 5% se sintetizaron por el método sol-gel. Los resultados de difracción de rayos X mostraron la formación de la fase anatasa en todos los compuestos, así como pequeñas contribuciones de la fase TiO2 (B) a 15° y 26° en 2θ. El análisis del refinamiento Rietveld calculó los porcentajes de las fases presentes en los compuestos. Las micrografías TEM y SEM identificaron las fases en los catalizadores y confirmaron el tamaño nanométrico y la morfología de los catalizadores. La espectroscopía UV-Vis reveló la reducción en el valor de la banda prohibida reconocido a la adición de cerio y lantano en los compuestos. Finalmente, las muestras fueron evaluadas en la degradación de 4-clorofenol mostrando una buena respuesta fotocatalítica.
Levels and fate of antimycotic pharmaceuticals at sewage treatment plantsJorge Casado Agrelo
Antimycotics are a broad group of drugs, active against infections caused by fungi, recognized as emerging environmental contaminants. Their most common way of use is the topic application, although they can be also administered orally or intravenous. Therefore, excretion and showering result in the introduction of these compounds in municipal sewage water[1 2]. These pharmaceuticals are suspected of being endocrine disruptors, since they work inhibiting some enzymes, such as aromatases, that are responsible for sexual differentiation of vertebrates and the balance between androgenic and estrogenic hormones in mammals[3]. Therefore, analytical methodologies that permit the analysis of different kinds of water, as well as sewage sludge, and the quantification of these dangerous pharmaceuticals are necessary. In this work we present the optimization of an improved selectivity enrichment method for the analysis of antimycotic drug residues in water and sludge samples.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
