From Microporous to Mesoporous Molecular-Sieve Materials and Their Use in Catalysis
TL;DR: Corma et al. as mentioned in this paper used the Dupont Award on new materials (1995), and the Spanish National Award “Leonardo Torres Quevedo” on Technology Research (1996) on technology research (1996), to recognize the performance of zeolites as catalysts for oil refining and petrochemistry.

Exposure of Engineered Nanoparticles to Human Lung Epithelial Cells: Influence of Chemical Composition and Catalytic Activity on Oxidative Stress
Ludwig K. Limbach,Peter Wick,Pius Manser,Robert N. Grass,and Arie Bruinink,Wendelin J. Stark +5 more
TL;DR: The present results indicate that the particles could efficiently enter the cells by a Trojan-horse type mechanism which provoked an up to eight times higher oxidative stress in the case of cobalt or manganese if compared to reference cultures exposed to aqueous solutions of the same metals.

Titania-silica as catalysts : molecular structural characteristics and physico-chemical properties
Xingtao Gao,Israel E. Wachs +1 more
TL;DR: In this paper, the similarities and differences in structural characteristics and physico-chemical properties between titania-silica mixed and supported oxides are emphasized, and the generation of new catalytic active sites either on the silica surface or in the matrix is discussed with respect to the formation of Ti-O-Si bonds and the local structure.

Microporous Crystalline Titanium Silicates
TL;DR: In this paper, the authors focused on the microporous crystalline titanium silicates and their catalytic properties in H2O2 oxidation reactions and attributed the unusual properties of titanium silicalites have been attributed to the presence of TiIV in framework positions of the SiO2 lattice.

Degradation of Acid Orange 7 using magnetic AgBr under visible light: the roles of oxidizing species.
TL;DR: It is found that the average diameter of the Ag/AgBr/SFN particle is less than 20 nm, which implies that the catalyst can be magnetically separated, and the effect of active h(+) and (*)OH were proven to be highly dependent on the concentration of photocatalysts.
