Introduction: During the healing process, the functional gradient attachment of the rotator cuff (RC) tendon-bone interface fails to regenerate, which severely impedes load transfer and stress dissipation, thereby increasing the risk of retears. As a result, the treatment of rotator cuff tears remains a significant clinical challenge.

Methods: In this study, a dual-crosslinked hyaluronic acid/polyethylene glycol (HA/PEG) hydrogel scaffold was synthesized using hyaluronic acid and polyethylene glycol as base materials.

Homogeneous photoluminescence (PL) line width of semiconductor nanocrystals is usually much greater than thermal broadening at room temperature (∼25 meV), limiting their applications as optical and optoelectronic materials. Here, homogeneous PL line width of zinc-blende CdSe nanocrystals with epitaxially grown CdS, ZnSe, and ZnS shells is studied using single-molecular spectroscopy, confirming that delocalization of electron and hole wave functions to the lattice-ligands interface dictates their PL homogeneous line width. Specially, epitaxial ZnSe (or ZnSe inner and ZnS outer) shells form type-I band offsets with CdSe cores, colocalizing both electron and hole wave functions within the ordered core lattice with minimum lattice strain.

Although cadmium stabilization through dissimilatory sulfate reduction (DSR), mediated by sulfate-reducing bacteria (SRB) has been extensively studied, the mutual interactions between cadmium and sulfur-cycle systems co-regulated by SRB and sulfur-oxidizing bacteria (SOB) remain poorly characterized. We examined physiological responses (growth kinetics, sulfur valence transitions, Cd tolerance) to determine how bacterially mediated bidirectional sulfur cycling influences cadmium speciation. Results demonstrate that SRB (Enterobacter quasihormaechei) immobilizes Cd anaerobically, forming CdS, as confirmed by XRD, FTIR, and SEM/EDS analyses.
