Summary: Waste fluorescent powder contains valuable rare earth elements, which can be efficiently recovered through microwave-assisted leaching. In this study, rare earth elements Y and Eu were leached from the waste phosphor with hydrochloric acid using microwave radiation. The maximum leaching rates of Y (99.84%) and Eu (89.82%) were achieved at 600 W microwave power, 60 min radiation time at 60°C. The microwave leaching process significantly reduced the reaction activation energy, shortened the reaction time, and facilitated the rapid and efficient leaching of rare earth elements in the waste phosphors.

Summary: This paper presents a bio-chemo-mechanical theoretical framework to model complex morphologies and dynamic behaviors in living thin structures. Hopf and Pitchfork bifurcations induced by chemomechanical feedback are found to be the primary mechanisms triggering pattern formation. The proposed numerical scheme can track the dynamic pattern evolution beyond the stationary state.

Summary: In this study, the effectiveness of phosphophoryn (PP) and dentin sialoprotein (DSP) as bio-inductive pulp capping materials was examined through in vitro and in vivo experiments. Intermediate-dose PP was found to enhance cell migration and differentiation, while recDSP/PP proteins stimulated DSP-PP transcript expression. In vivo experiments showed that intermediate-dose PP and recDSP/PP proteins induced less pulp inflammation and promoted reparative dentin formation.

Summary: Nano CaCO3 (nC), various polymer mediated nano CaCO3, and Eu3+ anchored nano CaCO3/PEG were synthesized from natural carbonate source (Dolomite) using a novel biomimetic synthesis method. The products were characterized and analyzed for their mineralogy, structure, thermal stability, and morphology. The results showed that the prepared samples had a calcite structure with a rhombohedral shape and good thermal stability. The products also exhibited a spherical and porous structure. The addition of Eu3+ in CaCO3 resulted in blue shifted absorption and emission peaks and red shifted band gap values. The photoluminescence quantum yield values of the samples were also measured. The product nCE(1) showed good photocatalytic activity against methylene blue in the photodegradation application.

Summary: This study proposed a new strategy to indirectly estimate the hydrogen diffusivity of metallic materials under tensile stress by combining the electrochemical hydrogen permeation test (EHPT), the hydrogen diffusion descriptive equation based on Fick's law, and hydrogen pre-charged tensile test. The results showed that the hydrogen permeation curve obtained was highly approximate to the theoretical trend. The hydrogen embrittlement (HE) susceptibility of the specimens increased with increasing stress.

Summary: Deposition of Pd/Pt/Au three-layer films on p-GaN under high and ultra-high vacuum conditions was studied to investigate the electrical contact properties. Linear I-V curves were observed in samples deposited under ultra-high vacuum conditions, while nonlinear I-V characteristics were obtained in samples deposited under high vacuum conditions. The study also found that the samples deposited under high vacuum conditions had higher amounts of oxygen and Pd oxide. The oxide layer had an additional influence on the electrical characteristics of the Pd/Pt/Au/p-GaN contact.

Summary: The corrosion behavior and microstructural evolution of Sc microalloyed Al-3.2Cu-1.5Li alloys were investigated in detail. The microstructural results showed higher levels of dislocations density in the Sc microalloyed sample, which resulted in significantly refined grains and T1 precipitates. Microalloying with Sc changed the corrosion mode of the alloy and localized corrosion was found to occur preferentially at the subgrain within unrecrystallized grains with high grain stored energy.
