Determining multiscale, concurrent strain, and deformation mechanisms in hierarchical biological materials is a crucial engineering goal, to understand structural optimization strategies in Nature. However, experimentally characterizing complex strain and displacement fields within a 3D hierarchical composite, in a multiscale full-field manner, is challenging. [...]

A thin membrane (≈47 μm) of a Celgard separator-reinforced cross-linked LiTFSI-PEO-Pyr14TFSI-LLZO composite polymer electrolyte (CgCPE) was prepared and investigated for its ability to suppress the formation and propagation of high surface area lithium (HSAL) with dendritic morphology. The membrane shows superior cycling stability in Li||Li-symmetric cells under high capacity utilization (5 mAh/cm2) for up to 2000 h. [...]

Hypothesis: In previous studies we looked at the foam stability of various surfactants with C12 alkyl chains but different head groups and found that stable foams are only generated if the head groups are capable of forming hydrogen bonds with each other. Despite the consistency of the experimental data with the conclusions drawn from it we had no direct proof for our hypothesis that H-bonds are formed between surfactant head groups. [...]

Oligothiophenes and their functionalized derivatives have been shown to be a viable option for high-performance organic electronic devices. The functionalization of oligothiophene-based materials allows further tailoring of their properties for specific applications. [...]

Nucleobases methylated at the glycosidic nitrogen atom achieve DNA-specific self-assembly upon heating in the solid state. We report formation and characterisation of the elusive cocrystal of methylated guanine and methylated cytosine, exhibiting Watson–Crick-type hydrogen bonding, and the crystal structure of 9-methylguanine..
