Part 1: Setting your workplace In March of this year, the Mexican government announces the suspension of activities in all the universities to prevent the spread of COVID-19. The first tactic was the implementation of social distancing ( Something that everybody can do during Coronavirus, Social Distancing). This tactic is working around the globe. However, not all the population have the opportunity to do a personal lockdown. Fortunately, academics, teachers, and researchers can. For a postdoctoral researcher like me who is doing nanoscience ( synthesis of thin-films), the main problem was to suspend the laboratory activities. My work is based…

Chemical solutions for CuS deposition

During my postdoctoral stay at the Physics Institute of BUAP one of my duties is the deposition of thin-film semiconductors. At this laboratory IFUAP-205, I have been doing chemistry activities like the preparation of precursors solutions. In Fig.1, I want to show you three vials with solutions of different molar concentrations used for copper sulfide thin-film deposition: Copper chloride (CuCl2), Sodium hydroxide (NaOH) and Thiourea (NH2CSNH2). These solutions were dissolved in deionized water and stirred using a magnetic plate. What I have learned here is that solutions should be prepared one day before or in the moment of the chemical…
