Nanostructured Cr-WS2 Solid Lubricant Coating for Space Applications
Abstract: Abstract Tungsten disulphide (WS2) is one of the widely used intrinsic low friction materials, which is commonly used in the form of coating. WS2 offers very low coefficient of friction only in non humid conditions. Presence of humidity destroys this property and restricts its utility. Modifying the structure of WS2 by adding certain metals helps in overcoming this limitation and in addition improves the mechanical properties. Further, deposition technique and …

Impact of Built Shape, Forms and Spaces on Human Psychology
Abstract: Shelter is the essential component for human survival, yet they know more about the effects of environmental conditions on human health than they know about how a building’s geometry affects the human brain. Typically, architects work on geometry to integrate the appearance of structures, but design-oriented geometry ignores human experience with respect to psychology and emotion. The psychological effects of architectural geometry on human senses, behaviors, and experiences are the …
