Summary: Delamination is a common failure mode for multilayered structures. Different shapes and sizes of delamination defects have varying sensitivity to guided wave frequencies. In this study, the use of multi-frequency localized wave energy for delamination identification is explored using laser ultrasonic guided waves. Experimental results show lower noises and more discernible profiles of delamination regions in both medial and non-medial delamination cases.

Summary: Microwave pre-treatment of canola seeds was found to be a superior alternative to conventional steam treatment, especially when cooking the seeds at specific temperatures resulted in increased oil yield. Additionally, microwave conditioning of whole canola seeds and subsequent cooking of flaked seeds produced higher oil yield under the same treatment conditions compared to steam treatment.

Summary: The study evaluated the application of megasonic waves in improving the degumming step of seed oil refining, leading to increased recovery of entrained oil in gums and higher gum yield. Megasonic-assisted acid degumming effectively reduced residual phosphorus content in canola and soybean oils, but was less effective in sunflower oil. Moreover, the megasonic treatment significantly reduced the loss of gum-entrained oil and enhanced the gum yield from the degumming process of canola, soybean, and sunflower oils.

Summary: This research demonstrates the controlled synthesis of graft and branched copolymers without intermediate purification using one-pot or one-pass processes. The formation of poly(methacrylate) copolymers with pendent reversible addition-fragmentation chain transfer (RAFT) agent functionalities was performed through selective photoactivation, followed by a nonselective photoinduced chain extension to provide tailored graft copolymers. By alternating the light sources, a range of macromolecular architectures could be prepared from the same starting materials, showing the versatility and flexibility of this approach.

Summary: RSM and CCD techniques were used to optimize the molecular structures of β-lactoglobulin (β-Lg) and α-lactalbumin (α-La) with reduced human IgE-reactivity through high-hydrostatic-pressure (HHP) processing. The study found that temperature, pressure, and the interaction between temperature and time had significant effects on the molecular changes of β-Lg induced by HHP. The optimal conditions resulted in minimal IgG-binding and undetectable human IgE-binding.

Summary: This study evaluated the efficacy of cold plasma-activated bubbles in treating algal-impacted waters. The results showed that both air and oxygen-activated bubbles were effective in reducing cell numbers and increasing cell damage and inactivation. However, oxygen-activated bubbles were preferred due to lower nitrite and nitrate concentrations in the treated water. The study also found that different reactive species had varying impacts on algal cell removal and damage.

Summary: The use of plasma-activated water (PAW) as an antimicrobial agent to inactivate Salmonella Typhimurium on chilled beef during meat washing was evaluated. PAW spraying and immersion achieved similar reductions against Salmonella Typhimurium, with spraying being preferred for commercial implementation. Meat washing with PAW improved microbial inactivation without negative impacts on meat quality parameters, but reduced redness, yellowness, and chroma values.
