Catalysis in Brazil

A Review of Aerogel Applications in Adsorption and Catalysis

Aerogels are a special class of porous material, which have excellent physicochemical properties such as low density, high porosity, high surface area and adjustable surface chemistry. Aerogels were first prepared several decades ago, but never truly commercialized due to their high cost. Technological advancements in the production and quality of different types of aerogel cut costs down and m...

Human Rights Diplomacy: Case Study of Brazil

Human rights diplomacy is considered as a consequence of globalization. While many norms and issues are extensively globalized, nonetheless they can be implemented based on cost and benefit analysis (i.e. maximization of benefits and minimization of costs). States have to take their responsibility of human rights by demonstrating their responsiveness towards their people, international organiza...

Studies in Asymmetric Catalysis: Supramolecular Catalysis and Borane-assisted Hydrogenation

Catalysis in reaction networks.

We define catalytic networks as chemical reaction networks with an essentially catalytic reaction pathway: one which is "on" in the presence of certain catalysts and "off" in their absence. We show that examples of catalytic networks include synthetic DNA molecular circuits that have been shown to perform signal amplification and molecular logic. Recall that a critical siphon is a subset of the...
