The micro-damage process zone during transverse cortical bone fracture: No ears at crack growth initiation
(Elsevier, 2017-10-01)Apply high-resolution benchtop micro-computed tomography (micro-CT) to gain greater understanding and knowledge of the formation of the micro-damage process zone formed during traverse fracture of cortical bone. Bovine ... -
Microbiome engineering to improve biocontrol and plant growth-promoting mechanisms
(Elsevier, 2018-03-01)A plant microbiome includes a microbial community that typically interacts extensively with a plant. The plant microbiome can survive either inside or outside of plant tissues, performing various plant beneficial activities ... -
A microfluidic chip integrated with droplet generation, pairing, trapping, merging, mixing and releasing
(Royal Society of Chemistry (RSC), 2017-03-16)Developing a microfluidic chip with multiple functions is highly demanded for practical applications, such as chemical analysis, diagnostics, particles synthesis and drug screening. This work demonstrates a microfluidic ... -
Microfluidic droplet trapping, splitting and merging with feedback controls and state space modelling
