Protecting Surfaces Using One-Dimensional Nanostructures
Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

متن کاملSurfaces Bearing Fluorinated Nucleoperfluorolipids for Potential Anti-Graffiti Surface Properties
Graffiti can sometimes be a problem when put in an inappropriate place. We looked at a means to prevent such inconvenience. In this work, we explore the possibility of developing surfaces with controlled wettability. If the paint does not spread, the graffiti does not stay. Here, the synthesis and electrodeposition of original 3,4-ethylenedioxythiophene (EDOT) with perfluorinated nucleolipids (...
متن کاملAnalysis of Scale from Some South African
Several samples of evaporator scale collected during the 1993 and 1994 milling seasons were analysed using x-ray diffraction, x-ray fluorescence, scanning electron microscopy and optical microscopy. The results were evaluated in terms ofcurrent knowledgeofevaporator foulingand similar trends were found to those published in the literature. From these results, typical evaporator scale profiles c...
متن کاملProtecting health workers from infectious disease transmission: an exploration of a Canadian-South African partnership of partnerships
BACKGROUND Health workers are at high risk of acquiring infectious diseases at work, especially in low and middle-income countries (LMIC) with critical health human resource deficiencies and limited implementation of occupational health and infection control measures. Amidst increasing interest in international partnerships to address such issues, how best to develop such collaborations is bein...
