 Within the CURRENT folder of the magazine, the following four papers have been published:
• History of Pandemics by Prof. Dr. Serdar TEZELMAN
• Virus Changing Our Lifestyle by Biologist Serdar ÖKTEM
• Pandemics and Economy by Assoc. Prof.Dr.Evren BOLGÜN
• Antimicrobial Paints and Coatings by Chemical Engineer Tolga DIRAZ
Last topic above, Antimicrobial Paints and Coatings, gives some details particularly on Hygienic Protection and Prevention Methods from Germs (Viruses, Bacteria, Fungi etc.) on Steel Surfaces. Paper includes the following subtopics:

What are Antimicrobial Coatings (AMCs)?
As a globally accepted definition, AMS are thin films having antimicrobial ingredients that is scientifically proven and applied to a surface to prevent the infectious diseases by killing or preventing the accumulation, growth and reproduction of pathogenic microorganisms that we call germs such as fungi, mould, mildew, algae, bacteria and virus. These films can be PVC, latex, lacquer, polyurethane, ink, powder coatings or just paint. The surfaces can be hard surfaces (steel, aluminium or metals along with plastics and composites) or textiles.
Contrary to common belief, AMCs mechanisms of action does not only include Killing action (i.e.Biocide Release) but also include Repelling action (i.e.Exclusion Steric Repulsion, Electrostatic Repulsion, Low Surface Energy)
The most critical application areas for AMCs are hospitals & healthcare organizations, food Industry, high traffic buildings (i.e.universities, institutes, schools, offices in the companies, firms, professional societies & associations and public buildings like libraries, post offices, amusement parks, multi-purpose halls), public transportation vehicles (i.esubways, trains, buses, taxis).
Major Differences Compared to Regular Paints &Coatings Specialized surface cleaning (often also include disinfection/sterilization methods) methods such as acid-etching, advanced inspection devices like 3D laser confocal microscope and specialized performance tests like Antimicrobial activity and efficacy tests are some example differences to conventional paints and coatings.
