Da harmonia do sorriso ao equilíbrio químico: proposta de situação de ensino e aprendizagem em química.
… showed low level of interest in studying Chemisty. They identified that Chemistry is more related to Biology and Physics than to Mathematics. Chemical equilibrium was regarded as a difficult topic to learn. After performing the TLS the students recognized that Chemistry can be important …

Preparation and Evaluation of Molecular Imaging Probes Targeting the Urokinase Plasminogen Activator System
… through the use of antibodies and bioorthogonal chemisty based on radiolabeled tetrazines and transcyclooctene (TCO) functionalized biomolecules. A new tetrazine synthon was developed that can be readily labeled with both 99mTc and 18F where the products were produced in 75 and 31 % radiochemical …

Surface chemistry and growth of oxide supported metal nanoparticles
A model heterogeneous catalyst inspired by a real catalyst is synthesized for the purpose of understanding how it works. To make such model catalysts, we choose to evaporate metal atoms on metal oxide single crystals and measure them under UHV conditions. The study of model catalysts could advance …

Probes of tocopherol biochemistry: fluorophores, imaging agents, and fake antioxidants
The body has many defence systems against reactive radical species, but none are as crucial in the protection of lipid membranes as vitamin E. As a result of a selection process mediated by the α-tocopherol transfer protein (α-TTP), α-tocopherol is the only form of vitamin E retained in the body. …

Studies Toward the Synthesis of Salvinorin A and Synthesis of Broad-Spectrum DENV/WNV NS3 Protease Inhibitors
Part I: Salvinorin A is the main active component of the plant Salvia divinorum. Salvia divinorum is native to the Mazatec region in Northern Oaxaca, Mexico. It has been used by local Mazatec Indians for its hallucinogenic properties in ritual divination and healing ceremonies. It is the first …
