Advances in nondestructive methods for meat quality and safety monitoring.

Kutsanedzie, F. Y.; Guo, Z.; Chen, Q. (Materials Science and Engineering:, 2019)

Meat is highly perishable and poses health threats when its quality and safety is unmonitored. Chemical methods of quality and safety determination are expensive, time-consuming and lack real-time monitoring applicability. ...
Analysis of electrochemical machining-textured surfaces under point contacts in rolling tribo-test.

Gyimah, G. K.; Oman, E. K.; Nyanor, P.; Acakpovi, A.; Jiang, S.; Guo, Z.; Barber, G. C. (Springer, Cham., 2021)

Purpose: The need for the right textured surface and selecting the right material in tribology is critical to friction reduction and energy savings in machine elements under full film lubrication rolling point contacts. ...
Application of powder metallurgy methods for production of a novel Cu-based composite frictional train brake material.

Gyimah, G. K.; Guo, Z.; Huang, P.; Chen, D. (Powder metallurgy-fundamentals and case studies, 2017)

A novel Cu-based composite frictional train brake material composed of several elements such as Al, SiO2, Fe, graphite, Sn, Mn and SiO2 re-enforced with other elements was treated under Powder Metallurgy (P/M) route. The ...
Influence of MoS2 and PTFE in oil film characteristics and tribological performance in EHL point contacts.

Gyimah, G. K.; Guo, Z.; Huang, P.; Jiang, S.; Barber, G. C.; Liu, J. (Tribology-Materials, Surfaces & Interfaces, 2019)

The use of improvers of viscosity index mixed with engine oil to enhance film thickness of lubricant, have been tribologically studied by the optical interferometry technique. The viscosity index improvers (PTFE and MoS2) ...
Portable spectroscopy system determination of acid value in peanut oil based on variables selection algorithms.

Yang, M.; Chen, Q.; Kutsanedzie, F. Y.; Yang, X.; Guo, Z.; Ouyang, Q. (Measurement, 2017)

The acid value (AV) is an essential parameter for the quality and safety evaluation of peanut oil. In this study, for efficiently and real-time monitor of acid value (AV) in peanut oil, a portable spectroscopy system was ...
Preparation of biomimetic superhydrophobic surface by a facile one-step pulse electrodeposition.

Jiang, S.; Guo, Z.; Gyimah, G. K.; Zhang, C.; Liu, G. (Procedia Cirp, 2018)

Superhydrophobic surfaces in natural world, such as lotus leaves, are commonly attributed to a combination of hierarchical micro/nano structures and low surface energy materials, giving inspiration for the preparation of ...
PTFE and MoS2 Additives for Mineral Oil Film Formation in EHL Point Contacts.

Gyimah, G. K.; Guo, Z.; Huang, P.; Jiang, S.; Barber, G. C. (ASME, 2016)

Lubricant film-forming viscosity index improvers blended with commercial engine oil have been developed and studied by using optical interferometry. The influence of the viscosity index improvers (PTFE and MoS2) mixed with ...
A rapid one-step process for fabrication of biomimetic superhydrophobic surfaces by pulse electrodeposition.

Jiang, S.; Guo, Z.; Liu, G.; Gyimah, G. K.; Li, X.; Dong, H (Materials, 2017)

Inspired by some typical plants such as lotus leaves, superhydrophobic surfaces are commonly prepared by a combination of low surface energy materials and hierarchical micro/nano structures. In this work, superhydrophobic ...
Rapid Pseudomonas species identification from chicken by integrating colorimetric sensors with near-infrared spectroscopy.

Xu, Y.; Kutsanedzie, F. Y.; Sun, H.; Wang, M.; Chen, Q.; Guo, Z.; Wu, J. (Food Analytical Methods, 2018)

Pseudomonas spp. are the dominant spoilage bacteria which can cause chicken spoilage. Some traditional detection methods are often unsuitable for their rapid real-time detection. Thus, in this paper, a fusion strategy based ...
