Preparation of Phase – Pure Nanocrystalline Anatase and Rutile TiO2 using Hydrolysis of TiCl4 in presence of surfactants
Abstract: Hydrolysis of TiCl4 was carried out in two different ways to prepare nano crystalline TiO2. In the first method the hydrolysis of TiCl4 was carried under high acidic conditions at low temperature. In the second method hydrolysis was carried out using (NH4)2SO4 as an additive. It can be seen that the hydrolysis of TiCl4 under high acidic conditions promotes the growth of rutile phase of TiO2, where as hydrolysis in …

Application of Guided Surgery Concepts in the Programming and Intraoperative Management of Apicoectomies using a Surgical Template: A Case Report
Abstract: Apicoectomies are Endodontic Microsurgical procedures that require high precision. However, the state-of-the-art method currently used provides for a certain degree of imprecision as it heavily relies on the clinician’s judgment and experience with the sole aid of preliminary radiographic investigations. This clinical study aims to apply the Surgical Guided Approach, frequently used in Implantology, to Apicoectomies, thereby ensuring higher precision and, therefore, a lower amount of bone tissue loss as …

Deep Plate: A Deep Learning Approach to Recipe Generation from Food Images
Abstract: In the deep learning era, image understanding is advancing in sophistication, encompassing both semantic interpretation and the generation of meaningful image descriptions. To achieve this, deep neural networks must undergo specific cross-model training; these networks must be both simple enough to handle a wide range of inputs and complex enough to encode the fine contextual information associated with the image. An appropriate example of the previously described picture comprehension problem …
