A comparison of different silver inks for printing of conductive tracks on paper substrates for rapid prototyping of electronic circuits

Author: Bezuidenhout, PH ; Smith, S ; Mbanjwa, M ; Land, KJ ; Joubert, T-H Date: Nov 2015 This study compares the performance between two commercially-available electrically conductive silver inks, Harima NPS-J nanopaste and the NBSIJ-FD02 Mitsubishi conductive ink, used in rapid prototyping of electronic circuits. The comparative ... Read more
Droplet-based microfluidic method for synthesis of microparticles

Author: Mbanjwa, MB ; Windvoel, TV ; Land, KJ Date: Oct 2012 Droplet-based microfluidics has, in recent years, received increased attention as an important tool for performing numerous methods in modern day chemistry and biology, such as synthesis of hydrogel microparticles. The droplet-based ... Read more
Experimental observation of capillary instabilities of two phase flow in a microfluidic T-junction

Author: Mbanjwa, MB ; Land, KJ ; Jewell, L ; Moss, EA ; Gledhill, Irvy MA Date: Jan 2010 This paper discusses the experimental observation of capillary instabilities of two-phase flow in a microfluidc T-junction. These instabilities are analogous to the classical Plateau-Rayleigh instabilities. The experiments were carried out ... Read more
Hybrid paper-based potentiostat for low-cost point-of-need diagnostics

Author: Bezuidenhout, PH ; Smith, S ; Land, KJ ; Joubert, T Date: Oct 2017 The focus of this paper is the manufacturing of a low-cost hybrid paper-based potentiostat. Potentiostats exhibit high sensitivity, and can be used for a variety of applications. The results highlight the functionality of a paper-based ... Read more
Improvement of the surface finish obtained by laser ablation with a Nd: YAG laser on pre-ablated tool steel

Author: Steyn, J ; Naidoo, Kuben ; Land, KJ Date: Jan 2007 Surface finish is an important requirement for tool and die makers and remains a challenge with conventional machining technologies. Nd: YAG lasers have been utilised for many years in the area of laser marking, engraving and micro machining. ... Read more
Microfluidics as a tool for micro-manipulation

Author: Potgieter, S ; Land, KJ ; Sparrow, RW ; Coetzee, R Date: Oct 2008 Microfluidics is a multi-disciplinary field that deals with the behaviour, control and manipulation of sub-millilitre fluid volumes. It is proving to be a useful tool for biological studies, affording advantages such as reduced cost, faster ... Read more
Novel mixing method for cross linker introduction into droplet emulsions

Author: Land, KJ ; Mbanjwa, MM ; Korvink, JG Date: Oct 2013 Microfluidic devices are commonly utilised for the manufacture of particles. In certain applications, cross linkers are required to manufacture these particles, and when introduced in continuous form will foul the microfluidic channels. We ... Read more
A paper-polymer centrifugal device for low-cost sample pre-concentration and colorimetric lateral flow assay enhancement

Author: Wiederoder, MS ; Smith, S ; Madzivhandila, P ; Mager, D ; Moodley, K ; DeVoe, DL ; Land, KJ Date: Oct 2016 This study describes a novel hybrid paper-polymer centrifugal microfluidic device for pre-concentration of E.coli and lateral flow immunoassay enhancement for water quality verification. The device balances rotational centrifugal force with ... Read more
Topological microfluidic structures for rapid mixing of emulsions

Author: Land, KJ ; Mbanjwa, MM ; Korvink, JG Date: Oct 2013 A novel use for topological structures inside microfluidic channels is presented. These structures have been successfully utilised to aid in mixing of two water-in-oil emulsions in order to force coalescence, thereby introducing a cross linker ... Read more
