Establishment of optimise strategies in production of recombinant Hepatitis B surface antigen for chip-based antibody detection approach
Published 2015“…The main results drawn showed that the IEC Q Sepharose XL column and optimum conditions of 4 mL sample loading volume, an elution buffer with 1.5 M NaCl concentration at pH 8 with an elution gradient length of 20 column volume and subsequent purification with SEC at a sample volume of 5 mL and a flow rate of 1 mL/min was able to efficiently purify HBsAg. An up-scaled version the established purification strategy comprising of the two techniques further demonstrated adaptability for scale-up operations with a final total PF of 94.82 ± 16.20, HBsAg purity of 95.48% and recovery yield of 78.07%. …”

HiPIMS deposition of VO2 thermochromic coating for enhanced optical properties
Published 2022“…In chapter 4, a HiPIMS deposition technique for VO2(M) thin film on a commercial material, such as soda-lime glass substrate, was established with a high deposition rate of 5.7 nm/min. The VO2(M) deposited on soda-lime glass exhibits excellent crystallinity and thermochromic properties (highest luminous transmission Tlum ≈ 30.4%, and solar modulation ΔTsol ≈ 12%) in comparison with similarly prepared VO2 on high temperature glass and quartz substrates. …”
