OCLC Number/Unique Identifier: 9014868388

Aim of this work is to analyze the coronavirus viral surface properties related the pattern of electrical features. This chemical physical property is relevant and crucial to set profile of diffusion, severity of disease, efficacy of therapeutic strategy and in order to search new way to fight COVID-19 and the NEW VARIANT. The phenomena of immune evasion and the different pattern of efficacy towards variants of some vaccine or some antibodies combination produce the need to verify if considering the electrical feature of viral surface can be a right tool or not. As result of this research it is possible to submit to the scientist that the viral surface properties and electrical feature can be an element to be considered in various preventive or treatment measure. The specificity of action of some vaccine or antibodies seem to tell us that also the aspecific methods are useful. A specific chemico physical factors can influence the electrical charges viral surface behavior. Hpertonic saline solution, humidity, electrical charge barrier in mask are simply example of the effect. That can be obtained action on viral surface chemico -physical properties.

An overview of the developments of nanotechnology and heterogeneous photocatalysis in the presence of metal nanoparticles

Published on: 20th September, 2022

OCLC Number/Unique Identifier: 9625606691

In general, nanotechnology can be understood as a technology of design, fabrication and applications of nanostructures and nanomaterials, as well as a fundamental understanding of the physical properties and phenomena of nanomaterials and nanostructures. In recent years the development of industries like textile, leather, paint, food, plastics, and cosmetics is enlarged and these industries are connected with the discarding of a vast number of organic pollutants which are harmful to microbes, aquatic systems, and human health by influencing the different parameters. So the fabrication of those nanomaterials (coupled or doped) to form heterojunctions provides an effective way to better harvest solar energy and facilitate charge separation and transfer, thus enhancing the photocatalytic activity and stability. We expect this review to provide a guideline for readers to gain a clear picture of the fabrication and application of different types of heterostructured photocatalysts. In this review, starting from the photocatalytic reaction mechanism and the preparation of the photocatalyst, we review the classification of current photocatalysts, preparation methods, a factor that affects photocatalytic reaction, characterization of photocatalysts, and the methods for improving photocatalytic performance. This review also aims to provide basic and comprehensive information on the industrialization of photocatalysis technology.

GELS as Pharmaceutical Form in Hospital Galenic Practice: Chemico-physical and Pharmaceutical Aspects

Published on: 10th February, 2025

This work aims to describe the chemical-physical properties of various GELS used as galenic forms in hospital pharmacy practice. After an overview of the excipients and method used three preparations are reported. LAT GEL is used as an anesthetic in an emergency (pediatry ) in treating little Traumatic lacerations of the skin and scalp, calcium gel is used as an antidote for fluoride acid burns, and Lidocaine viscose 2% oral gel is used in some pathological conditions like severe esophagitis in onco - hematological patients after radiotherapy or chemotherapy. The galenic role in the situation of some drug shortages was also analyzed.

Fast identification for Evidences in Crime Scene with Macroscopic Properties and Portable Techniques

Published on: 27th May, 2025

In this work we are concerned with identifying visible evidence that can only be observed with the naked eye and is required for experiments by forensic scientists. The search details include many visible physical properties that could be used to explain many unknowns in the crime scene, which means critical truths for different cases. The details include appearance phenomena such as color, odor, shape, size, material type, and inferred properties based on physical appearance. The properties discussed in this work can be further analyzed using specific portable apparatuses that could give very important information about the structure and nature of the properties of evidence in a crime scene. We also deal in this work with general expertise, which forensic scientists should understand and could treat to make the process of identification and characterization in crime scenes be done more systematically in a short time.
