Two saponins were isolated from the stem bark extract of Stachytarpheta angustifolia. Their structures were established by spectroscopic and chemical analysis as (23S, 25S) - 5α - spirostan – 24 – one - 3β, 23 – diol – 3 – O – {α – L – rhamnopyranosyl – (1→2) – [O – β - D - glucopyranosyl – (1→4)] – β - D – galactopyr…

In this thesis, a protein structure determination using chemical shifts is presented. The method is implemented in the open source PHAISTOS protein simulation framework. The method combines sampling from a generative model with a coarse-grained force field and an energy function that includes chemical shifts. The meth…

Display Omitted Selective wet etching of Si3N4 to SiO2 in H3PO4.Both etch rate and selectivity strongly related to the amount of fluorine added in H3PO4.Etch selectivity modulated by addition of fl...
Abstract : We report a nitrogen delta-doping technique to engineer monolayer planes of spin in single crystal diamond films. Isotopically pure 15N2 gas is briefly introduced to form a thin N-doped layer (1-2 nm thick) during chemical vapor deposition of a diamond film. Post growth electron irradiation creates vacancie…
Devido à alta resistência a corrosão, os aços inoxidáveis possuem uma larga aplicabilidade em diversos setores industriais, seja indústria química, petroquímica ou alimentícia. Buscando atender solicitações ainda mais severas, métodos que melhorem a relação resistência à corrosão e propriedades mecânicas destes aços t…
An energy-based model is developed to describe the periodic formation of voids/saddle reefs in hinge zones of chevron folds. Such patterns have been observed in a series of experiments on layers of paper, as well as in the field. A simplified hinge region in a stack of elastic layers, with straight limbs connected by…
Isolated hydrogen and hydrogen pairs in bulk diamond matrix have been studied\nusing density functional theory calculations. The electronic structure and\nstability of isolated and paired hydrogen defects are investigated at different\npossible lattice sites in pure diamond and boron doped diamond. Calculations\nrevea…

The direct hydroxylation of benzene to phenol by hydrogen peroxide over TS-1 catalysts is carried out in a three phase stainless steel reactor system. In this research, the effects of ions (H+, NH4+, NO3-, Cl- and CH3COO-) in solution by using three acids and two salts (hydrochloric acid, acetic acid, nitric acid, amm…
Advances in high-throughput, high-volume microscopy techniques have enabled the acquisition of extremely detailed anatomical structures on human or animal organs. The Knife-Edge Scanning Microscope (KESM) is one of the first instruments to produce sub-micrometer resolution ( ~1 µm^(3)) data from whole small animal bra…

SrAl4O7:Eu and SrAl4O7:Eu,Dy samples have been prepared using conventional solid state synthesis. Addition of boric acid improves phase purity and influences photoluminescence. Europium- doped samples show emission maxima at 485 nm and afterglow decay halftimes up to ~285 s. Co-doping with dysprosium shifts emission m…
We have imaged the excitation of small-amplitude spin-wave eigenmodes, localized within $\sim$ 100 nm of the vertices of nanoscale Ni$_{81}$Fe$_{19}$ ellipses, using time-resolved scanning transmission x-ray microscopy (STXM) at 2 GHz and resolution of 70 nm. Taking advantage of the buried-layer sensitivity of STXM, w…
Semiconductor nanocrystals are a topic of much interest in electrical engineering. Their use has been explored for many applications. This paper investigates the synthesis and characterization of CuInS2 and CdSe nanocrystals. As the nanocrystals were left in reaction for increasing amounts of time, the bandgap of the…
