  • Kumar, S (Elsevier, 2010-08)
    Development of Functionally Graded Materials (FGM) using Ultrasonic Consolidation (UC) needs the joining of different metallic foils together. The present work deals with the joining of stainless steel, Al and Cufoils. ...
  • Cele, HM; Ojijo, Vincent O; Chen, H; Kumar, S; Land, K; Joubert, T; De Villiers, MFR; Ray, SS (Elsevier, 2014-06)
    This article reports the modification of optical properties of biodegradable/biocompatible polylactide (PLA) using organically modified montmorillonite (OMMT) for microcantilever applications. PLA/OMMT composite films with ...
  • Kumar, S; Pityana, S (2010-03)
    Modification of Aluminium surface by injecting, dispersing and melting TiB2 powder with the help of a laser beam promises to enhance tribological properties of Aluminium. The present work consists of making single lines ...
  • Kumar, S; Pityana, S (2010-11)
    For making metallic products through Additive Manufacturing (AM) processes, laser-based systems play very significant roles. Laser-based processes such as Selective Laser Melting (SLM) and Laser Engineered Net Shaping ...
  • Govindasamy, K; Potgieter, S; Kumar, S; Land, K; Muzenda, E (2012-09)
    Microfluidics has found widespread application in the fields of molecular biology, DNA analysis and most recently, point of care diagnostics. We present a paper based microfluidic device for rapid, in-the-field detection ...
