   Abstract The rheology of highly crystalline magma regulates its mobility, which may, in turn, determine the occurrence and styles of volcanic eruptions. We measured the rheology of high‐temperature magma with a basaltic‐andesite composition to document the properties that govern the transition from solid‐like to liquid‐like behavior. The measured elasticity in the solid‐like regime is three orders of magnitude lower than the shear modulus for a viscous silicate melt at high frequency. A considerable reduction of shear modulus is observed by increasing strain amplitude, indicating that the crystals unjam and the magma undergoes liquefaction. Crystal‐rich magma behaves as a dense suspension in which rheology changes rapidly with increasing strain and strain rate. Such characteristics enable the rapid mobilization of magma to trigger eruptions.

   Abstract Cysteine-rich receptor-like-kinases (CRKs), a transmembrane subfamily of receptor-like kinase, play crucial roles in plant adaptation. As such cotton is the major source of fiber for the textile industry, but environmental stresses are limiting its growth and production. Here, we have performed a deep computational analysis ofCRKsin fiveGossypiumspecies, includingG. arboreum(60 genes), G. raimondii(74 genes), G. herbaceum(65 genes), G. hirsutum(118 genes), andG. barbadense(120 genes). All identified CRKs were classified into 11 major classes and 43 subclasses with the finding of several novel CRK-associated domains includingALMT, FUSC_2, Cript, FYVE,andPkinase. Of these,DUF26_DUF26_Pkinase_Tyrwas common and had elevated expression under different biotic and abiotic stresses. Moreover, the 35 land plants comparison identified several newCRKsdomain-architectures. Likewise, several SNPs and InDels were observed in CLCuD resistantG. hirsutum. The miRNA target side prediction and their expression profiling in different tissues predictedmiR172as a major CRK regulating miR. The expression profiling ofCRKsidentified multiple clusters with co-expression under certain stress conditions. The expression analysis under CLCuD highlighted the role ofGhCRK057, GhCRK059, GhCRK058, and GhCRK081in resistant accession. Overall, these results provided primary data for future potential functional analysis as well as a reference study for other agronomically important crops.

5. Thermally fabricated cobalt telluride in nitrogen-rich carbon dodecahedra as high-rate potassium and sodium ion battery anodes

   https://doi.org/10.1039/d2se00267a  

   Sarkar, Debasish; Das, Debanjan; Nagarajan, Sudhan; Mitlin, David (July 2022, Sustainable Energy & Fuels)

   Cobalt telluride anchored to nitrogen-rich carbon dodecahedra (CoTe@NCD) was synthesized by simultaneous pyrolysis-tellurium melt impregnation of ZIF-67 MOFs. The purely thermal method involved no secondary chemicals and no waste byproducts. The result is a microstructure consisting of nanoscale 86 wt% CoTe intermetallic nanoparticles contained within a thin N-rich carbon matrix. During electrochemical cycling, the 21 nm average diameter CoTe provides short diffusion paths for Na + /K + ions, which in conjunction with the electrically conducting carbon matrix allow for rapid potassiation or sodiation. As potassium ion battery (PIB and KIB) and sodium ion battery (NIB and SIB) anodes, CoTe@NCD demonstrates attractive reversible capacity, promising cycling stability, and state-of-the-art rate performance. For example, as a KIB anode, the CoTe@NCD electrode exhibits a reversible capacity of 380 mA h g −1 at 50 mA g −1 and a fast charge capacity of 136 mA h g −1 at 1000 mA g −1 . As a NIB anode, it also displays excellent rate capability achieving 620 mA h g −1 at 50 mA g −1 and 345 mA h g −1 at 1000 mA g −1 .
