1. Estudos de multicamadas auto-organizadas de ácidos fosfônicos por difração dispersiva em energia / Study of self-assembled multilayers of phosphonic acids by energy dispersive diffraction
Esta dissertação trata do estudo estrutural e termodinâmico de sistemas orgânicos auto-organizados utilizando diferentes técnicas de espalhamento de raios-x. Multicamadas autoorganizadas de dois tipos de moléculas de ácidos fosfônicos foram analisadas: para o OPA [Ácido octadecilfosfônico ¿ CH2(CH3)17PO(OH)2] e para o OcPA [Ácido octilfosfônico

2. Vectorially oriented membrane protein monolayers: profile structures via x-ray interferometry/holography.
X-ray interferometry/holography was applied to meridional x-ray diffraction data to determine uniquely the profile structures of a single monolayer of an integral membrane protein and a peripheral membrane protein, each tethered to the surface of a solid inorganic substrate. Bifunctional, organic self-assembled monolayers (SAMs) were utilized to tether the p

3. The first living systems: a bioenergetic perspective.
The first systems of molecules having the properties of the living state presumably self-assembled from a mixture of organic compounds available on the prebiotic Earth. To carry out the polymer synthesis characteristic of all forms of life, such systems would require one or more sources of energy to activate monomers to be incorporated into polymers. Possibl
