The synthesis of novel amphiphilic 5,5',6,6'-tetrachloro-benzimidacarbocyanine (TBC) dye derivatives with amino-propanediol head groups is reported, which only differ in stereochemistry (chiral enantiomers, meso-form, and conformer). For the achiral meso-form, a new synthetic route towards asymmetric cyanine dyes was established. All compounds form J-aggregates in water whose optical properties were characterized by spectroscopic methods. The supramolecular structure of the aggregates was investigated by cryo-transmission electron microscopy (cryo-TEM), cryo-electron tomo-graphy (cryo-ET), and atomic force microscopy (AFM) revealing extended sheet-like aggregates for the chiral enantiomers and nanotubes for the mesomer, respectively, while the conformer forms predominately needle-like crystals. The experiments demonstrate that the aggregation behavior of compounds can be controlled solely by head group stereochemistry which in case of the enantiomers enables formation of extended hydrogen bond chains by the hydroxyl functionalities. In case of the achiral meso-form, however, such chains turned out to be sterically excluded. © 2020 WILEY-VCH Verlag GmbH & Co.

A novel chiral compound comprising two types of chiral moieties with opposite helicities and temperature dependences is synthesized; this compound is added as a chiral dopant to a mixture of nematic liquid crystals to prepare a chiral nematic liquid crystal (N*-LC). The N*-LC containing the chiral dopant exhibits thermally invertible helicity to yield left- and right-handed helical senses at low and high temperatures, respectively. Interfacial polymerization of acetylene is achieved in the N*-LC by modulating the temperature. Helical polyacetylenes (H-PAs) that are synthesized at low (-12 °C) and high (28 °C) temperature show right- and left-handedness, respectively, in terms of the fibrils, fibril bundles, and spiral morphology. In addition, the helical sense of H-PA is opposite that of the N*-LC because of the peculiar polymerization mechanism for acetylene in the N*-LC. The current N*-LC is the first chiral reaction field that has not only the thermally invertible helical sense but also the chemical functions and stability needed to serve as the medium for polymer reactions. © 2020 WILEY-VCH Verlag GmbH & Co.

These genes encode the subunits of the β-cell ATP-sensitive potassium channel, a key component of the glucose-stimulated insulin secretion pathway. Mutations in the two genes cause dysregulated insulin secretion; inactivating mutations cause an oversecretion of insulin, leading to congenital hyperinsulinism, whereas activating mutations cause the opposing phenotype, diabetes. This review focuses on variants identified in ABCC8 and KCNJ11, the phenotypic spectrum and the treatment implications for individuals with pathogenic variants. © 2020 The Authors. Human Mutation published by Wiley Periodicals, Inc.Conjugation of proteins to AMP (AMPylation) is a prevalent post-translational modification (PTM) in human cells, involved in the regulation of unfolded protein response and neural development. Here we present a tailored pronucleotide probe suitable for in situ imaging and chemical proteomics profiling of AMPylated proteins. Using straightforward strain-promoted azide-alkyne click chemistry, the probe provides stable fluorescence labelling in living cells. © 2020 The Authors. Published by Wiley-VCH Verlag GmbH & Co.

As a result, a straightforward methodology was developed for the formation of different fluoroaryl substituted alkenes in which the central carbon-carbon double bond is in a twisted geometry. © 2020 WILEY-VCH Verlag GmbH & Co.

In the precise device architecture, the subtle but critical band splits by the giant Stark effect between atomic layers, varied by the momentum of electrons and external electric fields in device operation, has not yet been demonstrated or applied to design original devices with the full potential of atomically thin materials. Here, resonant tunneling spectroscopy based on the negligible quantum capacitance of 2D semiconductors in resonant tunneling transistors is reported. The bandgaps and sub-band structures of various channel materials could be demonstrated by the new conceptual spectroscopy at the device scale without debatable quasiparticle effects. Moreover, the band splits by the giant Stark effect in the channel materials could be probed, overcoming the limitations of conventional optical, photoemission, and tunneling spectroscopy. The resonant tunneling spectroscopy reveals essential and practical information for novel device applications. © 2020 WILEY-VCH Verlag GmbH & Co.

Compared with other stimuli, visible light is highly controllable both temporally and spatially with less damage to materials, which is more suitable for structural color patterning. Herein, a new diselenide-containing shape memory material is prepared and used for creating patterns via visible light stimulus. In this system, the structural color originates from birefringence of stretched materials, whose shapes can be fixed while maintaining the mechanical stress. The fixed stress can be released by diselenide metathesis under visible light irradiation. By regulating the wavelength or irradiation time with a commercial projector, the pattern with tunable structural colors is realized and the structural color pattern can be erased and rewritten arbitrarily. During the patterning process, the optical signal is first stored as mechanical signal and then transformed back to optical signal.
