In this thesis, we describe an efficient technique for rendering rich geometric details (e.g., surface mesostructure) of complex surfaces. We use sphere-tracing aided by directional distance maps (DDMs) for quickly finding ray-mesostructure intersections. High accuracy is achieved by analytically detecting such intersections. Further, space requirement is kept low by adaptively sampling the dis...

mesoporous tio2 has been prepared using a nonionic block copolymer (pluronic p-123) as structure-directing agent with sol-gel method. characterization of the product was carried out by means of x-ray diffraction (xrd), scanning electron microscopy (sem), thermogravimetry-differential scanning calorimetry (tg-dsc), nitrogen sorption isotherms, and uv-vis absorption spectroscopy. these analyses s...

BACKGROUND Bone fragility and an increase in susceptibility to fracture osteoporosis is characterized by a reduction in bone mass and the micro-architectural deterioration of bone tissue. There is no previous study regarding the effect of Cinnamomum burmanini Blume on osteoporosis. OBJECTIVE This study was aimed to investigate the effect of C. burmanini Blume on bone turnover marker, mineral ...

A bstract Based on the equations of state, one can infer underlying interaction potentials among black hole molecules in case Schwarzschild-AdS and charged AdS holes. The microscopic with potential arrange a specific way to form mesostructure, whose size is between macro (black system) micro molecules). As result, mesostructure leads emergence macroscopic phase. However, information about are s...

The present study attempts to incorporate methacrylate-based polymers into ordered lamellar organic/inorganic nanocomposite films composed of alternating SiO2/polymer layers. The films are prepared by dip-coating from a solution containing the monomers and silica precursors, thus leading to composite lamellar mesostructured materials through evaporation-induced self-assembly (EISA). A polymeriz...

We present a technique for generating microstructure-level facial geometry by augmenting a mesostructure-level facial scan with detail synthesized from a set of exemplar skin patches scanned at much higher resolution. We use constrained texture synthesis based on image analogies to increase the resolution of the facial scan in a way that is consistent with the scanned mesostructure. We digitize...

Surfactant or block copolymer-templated mesoporous films have been extensively explored, but achieving mesostructure coherence and unidirectional orientation over macroscopic dimensions has remained quite challenging for these self-assembled systems. Here, we extend the concepts associated with zone refinement of crystalline materials to soft templated mesoporous carbon films based on the coope...

Two mesostructured MCM-41 silicas that differ dramatically in hydrothermal stability have been examined by (29)Si MAS NMR spectroscopy and pair distribution function (PDF) analysis of synchrotron X-ray scattering data. The less stable mesostructure assembled from sodium silicate and the substantially more stable derivative made from fumed silica possess equivalent local framework wall structure...
