Sustainable Approach to Produce Polyurethane Composite Foams with Natural Materials

Synthesis of Polyurethane from One Hundred Percent Sustainable Natural Materials through Non-isocyanate Reactions

Investigation of Industrial Polyurethane Foams Modified with Antimicrobial Copper Nanoparticles

Antimicrobial copper nanoparticles (CuNPs) were electrosynthetized and applied to the controlled impregnation of industrial polyurethane foams used as padding in the textile production or as filters for air conditioning systems. CuNP-modified materials were investigated and characterized morphologically and spectroscopically, by means of Transmission Electron Microscopy (TEM), and X-ray Photoel...

The Modification of Polyurethane Foams Using New Boroorganic Polyols (II) Polyurethane Foams from Boron-Modified Hydroxypropyl Urea Derivatives

The work focuses on research related to determination of application possibility of new, ecofriendly boroorganic polyols in rigid polyurethane foams production. Polyols were obtained from hydroxypropyl urea derivatives esterified with boric acid and propylene carbonate. The influence of esterification type on properties of polyols and next on polyurethane foams properties was determined. Nitrog...

Sustainable Urban Development with a New Approach to Ethics

  Background: With the massive growth of cities in the last two or three decades and the multifaceted role these cities play, the planning and cultural management of cities has become strangely complex and difficult. In general, there are economic, social, cultural, educational and physical problems in most cities despite numerous complaints from people. The purpose of this study is to examine ...

Optimization of Natural Rhenium Irradiation Time to Produce Compositional Radiopharmaceutical

Introduction: Previously, 186Re and 188Re radioisotopes have been produced through appropriate activities, and each of them has been used for therapeutic applications. The 186Re and 188Re have unique properties, which make them proper for the treatment of  tumors in different sizes. The long-range 188Re, is suitabl...
