Resin coating technique is a unique method that improves the dentin bond strength of resin cements in indirect restorations. However, the weak link of a specimen bonded using the resin coating technique was reported to be the bonded interface between the resin coating material and resin cement. The purpose of this study, therefore, was to enhance the bonding performance between a resin coating material and a resin cement. Two light-cured flowable composites, Protect Liner F and Clearfil Flow FX, were used as coating materials, and two dual-cure composite materials, Panavia F 2.0 and Clearfil DC Core Automix, were used as resin cements. The ultimate tensile strength of each material and the microtensile bond strengths of the bonded specimens of resin coating material and resin cement were measured using a crosshead speed of 1.0 mm/min. Three-way ANOVA (p=0.05) revealed that the highest microtensile bond strength was obtained using a combination of Clearfil Flow FX and Clearfil DC Core Automix, and when the surface of the coating material was treated with ED Primer II. It was strongly suggested that materials with a higher ultimate tensile strength, when used in both resin coating and cementation, could enhance the bond strength between the two.

This paper employed a two-color double-pulse femtosecond laser (TDFL) technology for surface processing of carbon fiber reinforced polymers (CFRP). By exploring the changes in ablation thresholds for resin and carbon fiber under varying wavelengths and pulse numbers, optimal wavelength combinations were identified. Adjustments to processing parameters and pulse delay enabled precise removal of the CFRP surface, targeting resin while causing no damage to the underlying carbon fibers.

A new type of filler was added to epoxy resin to prepare a composite coating with excellent corrosion and weathering resistance. The simple synthesis process and nonpolluting raw materials of this filler contribute to the development of green chemistry. Specifically, lignin was encapsulated in mesoporous silica, the synergistic effect between the two resulted in the formation of lignin/mesoporous silica composite particles (MSN-L) with excellent ultraviolet (UV) resistance.

Bisphenol A (BPA) is used extensively in producing industrial chemicals such as plastic products, resin, and paper coatings. Concerns have been expressed regarding its possible detrimental consequences, especially on the reproductive system of mammals. Despite extensive study in this domain, there has been no targeted examination of the impact of BPA on F1 generation rabbits.

In this study, we investigated the efficiency of a bentonite/iron-coated sand (B/ICS) stabilizer in reducing the mobility and accumulation of heavy metals (Pb, Cd, Zn, and As) in contaminated sediments. Bentonite is effective in the adsorption of heavy metals, while ICS is effective in the adsorption of As. When combined, the stabilizer can be applied to mixed-contaminated sediments containing both heavy metals and As.
