Diverse and Selective Metal-Ligand Cooperative Routes for Activating Non-Functionalized Ketones.

The rhodium and iridium complexes [Cp*M(κ,,-)][SbF] (Cp* = η-CMe; M = Rh, ; Ir, ; = pyridinyl-amidine ligand) exhibit three different cooperative metal-ligand reactivity modes when interacting with nonfunctionalized ketones. With the methyl ketones CHCOR (R = CH, Ph, CF), activation of the ketone methyl C(sp)-H bond yields ketonyl compounds of formula [Cp*M(CHCOR)(κ,-)][SbF]. With the ketones (CF)CO and CFCOPh, the complexes add to the C═O double bond of the ketone.

Mesophilic anaerobic digestion of mixed sludge in CSTR and AnMBR systems: A perspective on microplastics fate.

Most microplastics (MPs) end up in the biosolids produced in wastewater treatment plants (WWTPs) and can pose contamination risks when the biosolids are applied to agriculture. This study evaluated the impact of mesophilic anaerobic digestion on the fate of MPs in WWTP sludge. For this, two laboratory-scale anaerobic digesters were operated in parallel, consisting of a continuous stirred tank reactor (CSTR) and a membrane bioreactor (AnMBR) equipped with an ultrafiltration membrane to decouple the hydraulic and sludge retention times.

Barriers to and enablers of physical activity and its association with daily steps after hospitalisation for a COPD exacerbation: what patients say matters.

Introduction: Exacerbations of COPD decrease physical activity. Physical activity interventions after these events are desirable but have had mixed results. Understanding the barriers to and enablers of physical activity may help to improve the results of these interventions.

First metatarsal osteotomy with an intramedullary locking plate is a good alternative for the reintervention of recurrent hallux valgus.

This study describes the results of first metatarsal (M1) distal osteotomy with an intramedullary locking plate in persistent/recurrent painful hallux valgus (HV) deformity (without advanced degenerative changes) after primary surgery. Outcomes included postoperative incidences of HV angle (HVA)<16°, intermetatarsal angle (IMA)<9°, proximal articular set angle (PASA)<10°, and the American Orthopedic Foot and Ankle Society (AOFAS) score. Data normality was assessed with the Shapiro-Wilk test, and preoperative vs.

Programmable Magnetic Hysteresis in Orthogonally-Twisted 2D CrSBr Magnets via Stacking Engineering.

Twisting 2D van der Waals magnets allows the formation and control of different spin-textures, as skyrmions or magnetic domains. Beyond the rotation angle, different spin reversal processes can be engineered by increasing the number of magnetic layers forming the twisted van der Waals heterostructure. Here, pristine monolayers and bilayers of the A-type antiferromagnet CrSBr are considered as building blocks.
