In this study, 5% w/v SMP dispersion was acidified to pH 2.4–3.0 using citric acid and heated at different conditions. Lowering pH resulted in dissolution of colloidal calcium phosphate from casein micelles, corresponding to lowered turbidity and reduced hydrodynamic diameter of dispersions. When heated for 10 min at different temperatures, 70 °C was the most effective to produce transparent dispersions; whereas a shorter heating time between 2 and 60 min was desired at 90 °C. The decreased turbidity after heating was attributed to weakened hydrophobic interaction between casein molecules based on f...

Abdallah, Mohamed S.Mohamed AhmedAbstractEthyl 2-(1,2,3,6-tetrahydro-6-oxo-2-thioxopyrimidin-4-yl)ethanoate (EOTPE) was synthesized by a facile and cost-effective method. The structure confirmation of the synthesized EOTPE was performed by different spectroscopic methods. The corrosion inhibition action of EOTPE in pickling acids (1.0 N HCl and1.0 N H2SO4) at different temperatures (30–60 °C) was tested by various surface and corrosion methods, including open circuit potential (...

The HC-NCF consists of a single ring of eight nontouching silica capillaries around the air core, providing a single-mode light delivery of the 2.3-µm distributed feedback laser. A high coupling efficiency of 90% was achieved with the aid of optimal free-space coupling...

In this study, a new model was established to evaluate the van der Waals force between a rough surface and a deposited particle. In the new model, a surface was not modeled with any given geometrics, and no artificially defined coefficients were involved. A concise function was proposed, where the derived particle-surface force was inversely proportional to the particle’s normal position on the surface. Atomic force microscopy experiments were performed with a novel method to validate the new theory. A target particle was used to scan an area of a surface twice to obtain a height map and a force map. Data on the meas...

To explore whether HYL can be applied in anti-tumor therapy, we synthesized HYL and further modified its structure by using a solid-phase synthesis method, and then evaluated their antitumor activities. Firstly, we identified the key residues of HYL by alanine scanning strategy, and then a series of stapled pept...

However, IVC filters have been associated with risks, including IVC perforation, filter migration, fracture, and thrombosis. Filter retrieval has not always been successful. Our objective was to identify the factors associated with failure of retrieval of IVC filters.Meth...
