Background and purpose - We have previously shown that specific exercises reduced the need for surgery in subacromial pain patients at 1-year follow-up. We have now investigated whether this result was maintained after 5 years and compared the outcomes of surgery and non-surgical treatment. Patients and methods - 97 patients were included in the previously reported randomized study of patients on a waiting list for surgery. These patients were randomized to specific or unspecific exercises. After 3 months of exercises the patients were asked if they still wanted surgery and this was also assessed at the present 5-year follow-up...

Low-dimensional organometallic halide perovskites are actively studied for light emitting applications due to their properties such as enlarged exciton binding energy and tunable band-gap. Introduction of large-group ammonium halides not only serves as a convenient and versatile method to obtain layered perovskites, but also allows the exploitation of energy funneling process to achieve high efficiency light emission. Herein, we investigate the influence of the ethylammonium bromide (EABr) addition on the morphology, structure and optical properties of the resultant perovskite materials and report that the phase transition from bulk to layered perovskite occurs in presence of a large amount of EABr...

The effects of Li/Nb ratio on the preparation of Li-Nb-O compounds by a hydrothermal method were studied deeply. Li/Nb ratio has a great impact on the formation of LiNbO3; the ratio smaller than 3:1 is beneficial to the formation of LiNbO3, while larger than 3:1, forms no LiNbO3 at all and the morphology and chemical bond of Nb2O5 raw material are totally modified by Li ions. The reason can be attributed to the large content of LiOH, which is beneficial to form Li3NbO4 not LiNbO3, and also, even if LiNbO3 particle locally forms, it is easily dissolved in LiOH solution with strong alkalinity...
