Biomaterials. The Behavior of Stainless Steel as a Biomaterial

The biomaterials belong to the broad range of biocompatible chemical substances (sometimes even an element), which can be used for a period of time to treat or replace a tissue, organ or function of the human body. These materials bring many advantages in the diagnosis, prevention and medical therapy, reducing downtime for patients, restoring their biological functions, improving hospital management. The market in Romania sells a wide range of biomaterials for dental, cardiovascular medicine, renal, etc. Scientific research contributes to the discovery of new biomaterials or testing known biomaterials, for finding new applications. The paper exemplifies this contribution by presenting the testing of passive stainless steel behaviour in albumin solution using technique of cyclic voltammetry. It was shown that passivation contribute to increased stability of stainless steel implants to corrosive body fluids.biological environment, biomaterials, corrosion, cyclic voltammetry, stainless steel.

Auxiliaries for the textile industry and environmental protection

The textile industry is an industrial field that affects the environment, from the plant growth until the production process. The obtaining of environmental licence for Romanian companies that produce textile products is related to elaboration and implementation of a modern system for an environmental management, that consist in utilization of ecological technologies for finishing, in diminution the water and energy consumption, cleaning of waste waters, reutilization of cleaned waters, sustainable management of wastes. In this study, the surfactant categories used in the textile industry that fulfil the conditions of environment protection, are presented. Some exemplifications were made involving the existing surfactants in Romanian textile industry, obtained from both domestic and external production. Also, some recommendation are suggested regarding the utilization of surfactants manufactured from either vegetal oils or chemical/petrochemical wastes, with similar properties as those from import having decreased prices an that affect as small as possible the environment.textile industry, surfactant, pollution, environmental protection

New elastoplastic materials with performance properties

The fabrication of high performance materials using EPDM rubber and polyethylene mixtures with a low cost, nonpolluting and minimum investment technology is studied. These new materials can be used for obtaining a lot of goods for the economy, sport and private life..performance materials, advanced materials, synthetic rubber, plasticmaterials

The necessity of amplifying the environmental standards within industrial parks in Romania

The more and more frequent relocation of industrial companies within industrial parks, as a consequence of amplifying the urban areas’ environmental regulations, is due to generate uncontrollable pollution centers, placed just nearby towns and cities, with highly destructive impact upon the environment. This article aims to emphasize a new methodology for approaching the economic activities, within industrial parks, in an ecologic manner. Also, the article underlines sustainable advantages outcoming from promoting the development of ecological-based economic activities within each company located in a certain industrial park.ecology, environmental law, environmental protection, environmental standards, industrial parks, methodology, pollution
