  • 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 ...
  • Mbanjwa, M; Chen, H; Fourie, L; Ngwenya, S; Land, K (SPIE Digital Library, 2014-06)
    Multiplexed or parallelised droplet microfluidic systems allow for increased throughput in the production of emulsions and microparticles, while maintaining a small footprint and utilising minimal ancillary equipment. The ...
  • Joubert, T-H; Bezuidenhout, PH; Chen, H; Smith, S; Land, K (Elsevier, 2015-08)
    Inkjet printing is a widely used patterning method in industrial and scientific applications, and has also drawn attention in the field of printed electronics in recent years [1]. In this work, conductive silver tracks ...
  • Smith, S; Moodley, K; Govender, Ureshnie; Chen, H; Fourie, L; Ngwenya, S; Kumar, S; Mjwana, P; Cele, H; Mbanjwa, MB; Potgieter, S; Joubert, T-H; Land, K (Academy of Science of South Africa (ASSAf), 2015-11)
    Current centralised healthcare models pose many challenges, particularly for developing countries such as South Africa, where travel and time costs make it difficult for patients to seek healthcare, even when urgently ...
  • Smith, S; Chen, H; Moodley, K; Joubert, T; Land, K (RAPDASA, 2014-11)
    We present a method for rapid and low-cost development of microfluidic diagnostic devices using paper-based techniques. Specifically, the implementation of fluidic flow paths and electronics on paper are demonstrated, with ...
  • Chen, H; Ojijo, Vincent O; Cele, H; Joubert, T; Ray, SS; Land, K (SPIE Proceedings, 2014-03)
    SU-8/Clay nanocomposite is considered as a candidate material for microcantilever sensor fabrication. Organically modified montmorillonite clay nanoparticles are dispersed in the universally used negative photoresist polymer ...
  • Chen, H; Botef, I; Guduri, B; Vallabhapurapu, S (2009-12)
    The authors consider Polydimethylsiloxane (PDMS) as a prospective structural material candidate for a Micro Fuel Cell. The introduction of such a polymer as structural material will reduce the mass and the size of the micro ...
  • Chen, H; Botef, I; Zheng, H; Maaza, M; Vasudeva Rao, V; Srinivasu, VV (Inderscience Publishers, 2011)
    Carbon black filled Polydimethylsiloxane (PDMS) was considered as a prospective bipolar plate material candidate for a Fuel Cell. In this perspective, thermal conductivity and stability of the composites were investigated. ...
