1. MICROPLÁSTICOS: USO NA INDÚSTRIA COSMÉTICA E IMPACTOS NO AMBIENTE AQUÁTICO
Environmental pollution from plastics and microplastics is currently one of the most relevant issues of the scientific community and cosmetic industry. In particular, microplastics are referred to as small pieces of plastic less than five millimeters (<5mm) and do not dissolve in water, can be harmful to the ocean and aquatic life. Microplastics can be desig

3. On the possibility of obtaining high-quality lyophilized collagen hydrolysate and its applicability in the sausage production
Abstract The paper discusses the issues of rational use of secondary collagen-containing raw material in the food industry, namely cattle by-products. The technology of obtaining collagen hydrolysate from this type of raw material with the subsequent freeze-drying is proposed, which maximizes the level of preservation of native properties and the expands the

4. APLICAÇÃO DE NANOPARTÍCULAS DE FERRO ZERO-VALENTE (nFeZ) NA REMEDIAÇÃO DE SOLOS E ÁGUAS SUBTERRÂNEAS CONTAMINADAS: UMA REVISÃO
The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an im

5. EFFECT OF CYCLOPENTANE HYDRATES ON THE STABILITY OF DODAC AND AOT STRUCTURES
Abstract Hydrates are crystalline structures formed by water and substances with low molar mass molecules. Hydrate formation can occur during oil production when oil, gas and water flow through the same lines in conditions of high pressure and low temperatures. The deposition of hydrate crystals in production lines can severely jeopardize the safety of oper
