Metal organophosphonates have been explored in energy-related fields due to their high chemical and thermal stability as a type of uniformly precursor,but only few of pristine metal organophosphonate are directly used for oxygen evolution reaction(OER)catalysts.Here,a mixedvalence iron phosphonate(Fe_(3)-ppat)has been constructed and applied to OER catalysis considered the potential active sites in pillars Fe^(Ⅱ)(-H_(2)O)_(4)(COO)_(2)and inorganic layers Fe^(Ⅲ)(μ_(2)–OH)PO_(3).Specifically,isostructural trimetallic framework Fe_(1.7)Co_(0.3)Ni_(1.0)-ppat possesses a minimum overpotential(291 mV),small Tafel slope(91.65 mV dec^(-1)),and high stability up to 83 h.The enhanced catalytic performance could be mainly ascribed to the synergistic effect of Ni^(Ⅱ)equivalent occupancy in pillars and Co/Fe^(Ⅲ)in layers.

Adult tissue-derived organoids allow for the expansion and maintenance of primary epithelial cells in a near-native state.These 3D and self-organizing organotypic cultures derived from adult tissues have been increasingly used in fundamental and translational research.A key feature of this organoid system is that it recapitulates the stem cell lineage and thus,the differentiated cell-type heterogeneity of the in vivo tissue of origin.

Summary of main observation and conclusion Selenium and copper synergistically catalyzed the oxidation/alkoxylation of methyl ketones to synthesize a-keto acetals directly.Using 02 as oxidant and alcohol as solvent and alkoxylation reagent,the reaction is practical from industrial viewpoint.Mechanistic studies revealed that copper promoted the oxidation of organoselenium intermediates with O2 to allow the key rearrangement and selenoxide syn-elim-ination regenerating the catalytically active organoselenium species.

Dear Editor,Human cell-based and personalized in vitro cartilage models are urgently needed for osteoarthritis treatment in pre-clinical regenerative medicine development.Cellular self-assemblies and condensations of the appropriate stem cells could initiate the formation of transient tissue structures programmed for specific organogenesis processes.1 This recapitulation of developmental events has previously been demonstrated for the formation of cardiac,epithelial and liver organoids.However,there has been very limited progress in the development of human cartilage organoids for osteoarthritis(OA).2 Here,we describe the fabrication of functional bioengineered cartilage organoid suitable for OA treatment.Briefly,agarose microwell inserts for formation of a high number of synovial mesenchymal stromal cell(SMSC)organoids with homogeneous size distribution were created as previously described by Leijten et al.33D-cultured SMSC organoids were generated and phenotypically analyzed for potential applications in OA modeling and treatment(Fig.1a).

The considerable utility of organoboranes in synthesis is firmly established,which is in a large part due to the power of the Suzuki-Miyaura cross-coupling reaction for con・structing C-C bonds.Therefore,discovering simple new routes to form desirable organoboranes continues to be of significant import.Methodologies that directly transform C-H into C-B are particularly desirable,especially if borylation occurs with excellent site selectivity and without precious metal catalysts due to their low crustal abundance,high cost and toxicity.

Inspired by the freezing tolerance performances found in living creatures, an effect approach is presented to develop novelantifreezing polymeric organohydrogel actuators. Through construction of a bilayer hydrogel including a nonresponsivepolyacrylamide (PAAm) layer and a pH-responsive polyacrylic acid (PAA) layer in the presence of a mixed solvent of water andglycerol, organohydrogel actuators that could produce various shape deformations at subzero temperatures have been achieved,and the actuating speed could be tuned by adjusting the temperature and the ratio between glycerol and water. Moreover, aseries of application demonstrations including a weightlifting robot, artificial valve, and robotic arm have been displayed. Inaddition, by introducing the ionic compound KI into the glycerol-based organogel, flexible conductors that could perform stablesensing performance over a wide range of temperatures from -30℃ to 60℃ have been developed.
