Round shoulder posture (RSP) may exaggerate symptoms of subacromial impingement. The effects of kinesiology taping with exercise on posture, pain, and functional performance were investigated in subjects with impingement and RSP. This study was a single-blinded randomized controlled trial. An outpatient rehabilitation clinic in a university hospital. Thirty-four subjects with subacromial impingement and RSP. Kinesiology taping with and without tension was applied 2 times per week for 4 weeks. Both groups also performed strengthening and stretching exercises 3 times per week for 4 weeks. The pain level, shoulder angle and self-reported score were evaluated at pre-intervention, 2-week post-intervention and 4-week post-intervention time points. Functional performance improved after intervention in both groups (p = 0.027). A greater decrease in pain level was related to better functional performance of the shoulder in both groups (r = −0.760 and −0.674; p < 0.010). Moderate correlations were found for posture and functional performance of the shoulder in the intervention group (0.48). Four weeks of strengthening and stretching exercises with or without kinesiology taping improved functional performance in subjects with impingement and RSP. Improvement in clinical symptoms was related to better performance of posture. • Four weeks of strengthening and stretching exercises improves functional performance in subjects with impingement and RSP. • Kinesiology taping did not demonstrate an additional effect on RSP in our sample. • For subjects with SIS and RSP, improvement in clinical symptoms like pain and functional activity are related to better performance of posture.

Recent advances in the use of organic-inorganic hybrid perovskites have been investigated in a variety of applications, such as solar cells, photodetectors, light-emitting devices, and lasers, because of their outstanding semiconductor properties. Furthermore, the perovskite structure can host extrinsic elements, making it a promising candidate for battery applications. Previous studies have shown that organic-inorganic hybrid perovskites can be suitable anode materials for both lithium- and sodium-ion batteries. However, multivalent rechargeable batteries with perovskite materials have not yet been realized. Herein, we studied the electrochemical performance of three-dimensional (CH 3 NH 3 PbI 3 (MAPbI 3) and long-chain alkylammonium (C 4 H 9 NH 3) 2 (CH 3 NH 3) 3 Pb 4 I 13 ((i BA) 2 (MA) 3 Pb 4 I 13) thin films as electrode materials for rechargeable Al-ion batteries. Our results showed that (i BA) 2 (MA) 3 Pb 4 I 13 presented a specific capacity of 257 mAh g–1 at a current density of 0.1 A g−1 and delivered 108 mAh g–1 after 250 cycles at a current density of 0.3 A g−1 with a retention of as high as 91 %, demonstrating a crucial role of isobutyl amine (C 4 H 9 NH 3) due to the unique hydrogen-bonding interaction of isobutyl amine that hinders the shuttle effect of polyiodide. The results open a new direction for the use of organic–inorganic hybrid perovskites for new secondary aluminum ion batteries.

A suitable electrocatalyst plays an essential role in room-temperature Na–S (RT/Na–S) batteries owing to the more severe dissolution of polysulfides and sluggish kinetics of the conversion of polysulfides during charging and discharging processes. In this study, a novel MoS 2 /MoN heterostructure synthesized via NH 3 annealing was introduced as an electrocatalyst into RT/Na–S batteries to promote the evolution of polysulfides in the catholyte with an initial specific capacity of 703 mA h g−1 and retains 392 mA h g−1 after 300 cycles. The density-functional theory (DFT) calculations, ex-situ XPS and Raman spectra were utilized to reveal moderate anchoring and the fast redox kinetics of polysulfides, significantly enhancing the cycling performance and electrochemical performance of the RT-Na/S batteries when compared with those of the RT-Na/S batteries containing pure MoS 2 or MoN as the catalyst. The work provides a new strategy for guiding the design of high‐performance catalysts with manipulated chemical components and optimized adsorption ability.

• Firstly report of Bi/BiOBr microspheres with dominant exposed (0 0 1) facets. • Superior performance of Bi/BiOBr-001-m over other BiOBr catalysts. • Synergistic effect of crystal structures engineering and doped Bi element. • Sensitization effect of adsorbed RhB for bettering photocatalyst property. A facile one-step solvothermal process was used to synthesize Bi-doped BiOBr microspheres with mainly the (0 0 1) crystal facet exposed (Bi/BiOBr-001-m), which exhibited enhanced photocatalytic performance. The photocatalytic performance and stability of the obtained Bi/BiOBr-001-m photocatalyst for Cr(VI) photoreduction removal and rhodamine B (RhB) photooxidation degradation were significantly better than those of pure BiOBr and Bi-doped BiOBr microspheres. The enhanced performance is ascribed to the retarding effect of photoinduced electron–hole recombination caused by Bi doping and the predominant (0 0 1) crystal plane composite structure. The photocatalytic performance could be further boosted by the adsorbed RhB owing to the dye sensitization effect. This work provides a reference for effectively improving the photocatalytic performance by combining crystal facet engineering and element doping. [ABSTRACT FROM AUTHOR]
