Polydimethylsiloxane (PDMS), as the benchmark of organophilic membrane materials, still faces challenges for removal of aromatic compounds due to the undesirable transport channels. In this work, we propose to reconstruct the PDMS conformation with tunable side group mobility by introducing phenyl as rigid molecular spacer to relieve steric hindrance of large‐sized aromatic molecules; meanwhile, polymer segments are loosely stacked to provide additional degrees of freedom as increasing the permeant size. Moreover, the reconstructed PDMS is engineered into the composite membrane with prevention of condensation of aromatic compounds in the substrate pores. The resulting thin‐film composite membrane achieved one order of magnitude higher flux (11.8 kg m −2  h −1 ) with an equivalent separation factor (12.3) compared with the state‐of‐the‐art membranes for aromatic removal. The permeant‐customized membrane molecular and microstructure designing strategy opens a new avenue to develop membranes for specific separation targets.

Artificial self‐assembly systems typically exhibit limited capability in creating nature‐inspired complex materials with advanced functionalities. Here, an effective co‐assembly strategy is demonstrated for the facile creation of complex photonic structures with intriguing light reflections. Two different lipophilic and amphiphilic bottlebrush block copolymers (BCPs) are placed within shrinking droplets to enable a cooperative working mechanism of microphase segregation and organized spontaneous emulsification, respectively. Layer assemblies of the lipophilic BCP and uniform water nanodroplets stabilized by the bottlebrush surfactant are both generated, and co‐assembled into a bridged lamellar structure with the alternating arrangement of layers and closely packed nanodroplet arrays. Janus microspheres with diverse dual optical characteristics are successfully fabricated, and reflected wavelengths of light are highly tunable simply by changing the formulation or molecular weight of BCP.

Auf Grund der Readschen Theorie wurde die Lage des Versetzungsakzeptorniveaus in n‐leitendem Ge bestimmt. Es liegt 0,13 bis 0,18 eV unter der Leitungsbandkante und ist unabhängig von der Art der eingeführten Versetzungen. Der Einfluß der Inhomogenität der Deformation und der Punktdefekte, die während des Deformationsprozesses eingeführt werden, auf die Genauigkeit der Bestimmung der Lage des Versetzungsniveaus wurde in Betracht gezogen. — Durch Belegen der Oberflächen der Proben mit Sn wurde die Diffusion der Fremdatome auf ein Minimum herabgesetzt. Es wurde ein sehr starker Einfluß von Defekten, die nicht von Versetzungen herrühren und während der Deformation eingeführt wurden, auf die Beweglichkeit und die magnetische Widerstandsänderung beobachtet. Eine Änderung der Beweglichkeit bei Stromfluß parallel zur Versetzungsrichtung wurde Festgestellt.

An energy transfer‐based signal amplification relay concept enabling transmission of bioorthogonally activatable fluorogenicity of blue‐excitable coumarins to yellow/red emitting cyanine frames is presented. Such relay mechanism resulted in improved cyanine fluorogenicities together with increased photostabilities and large apparent Stokes‐shifts allowing lower background fluorescence even in no‐wash bioorthogonal fluorogenic labeling schemes of intracellular structures in live cells. These energy transfer dyads sharing the same donor moiety together with their parent donor molecule allowed three‐color imaging of intracellular targets using one single excitation source with separate emission windows. Sub‐diffraction imaging of intracellular structures using the bioorthogonally activatable FRET dyads by STED microscopy is also presented.

Minima in der Temperaturabhängigkeit des elektrischen Widerstandes wurden bei gewissen unverdünnten hexagonalen CeLa und CeY Legierungen beobachtet. Diese Minima können als ein Spin‐kompensierter magnetischer Zustand gedeutet werden. Für die CeLa Leigerungen mit La ⪆ 21 at% stimmen die von Widerstandsmessungen erhaltenen Néel‐Temperaturen nicht mit denen überein, die von magnetischen Messungen herrühren.

Mit Hilfe der Kernresonanzfluoreszenz‐Methode wurde das Abbremsverhalten von 3 eV‐Sm 152 ‐Rückstoßkernen, die durch Neutrinoemission aus Eu 152m entstehen, in einem Eu 2 (WO 4 ) 3 ‐Einkristall untersucht. Es wurde die erwartete Abhängigkeit der KRF‐Ausbeute von der Flugrichtung der Sm‐Kerne im anisotropen Potentialfeld des Kristalls festgestellt. Die zweifache Drehsymmetrie der b 0 ‐Achse des monoklinen Kristalls und der Achsenwinkel β bildeten sich in den Meßergebnissen ab. Der maximale KRF‐Ausbeuteunterschied betrug dabei (3,9 ± 0,1)%. — Modellvorstellungen, die von einem nichtkugelsymmetrischen Parabelpotential ausgingen, gestatteten die Berechnung der theoretischen KRF‐Ausbeute. Durch Vergleich mit den Meßergebnissen konnten die in diesem Modell vorkommenden freien Parameter bestimmt werden.

Construction of well‐defined sulfur‐rich macromolecules in a facile manner is an interesting but challenging topic. Herein, we disclose how to readily construct well‐defined triblock sulfur‐rich thermoplastic elastomers via a self‐switchable isothiocyanate/episulfide copolymerization and air‐assisted oxidative coupling strategy. During self‐switchable polymerization, alternating copolymerization of isothiocyanate and episulfide occurs initially due to the lower energy barrier for isothiocyanate insertion with respect to successive episulfide ring‐opening. After exhaustion of isothiocyanate, ring‐opening polymerization of episulfide begins, providing diblock polymers. Subsequent exposure of the reaction to air leads to a transformation of diblock copolymers into triblock thermoplastic elastomers. This protocol can be extended to diverse isothiocyanates and episulfides, allowing fine‐tuning of the performance of the produced sulfur‐rich thermoplastic elastomers.

Insufficient active sites and weak vertical conduction are the intrinsic factors that restrict the electrocatalytic HER for transition‐metal dichalcogenides. As a prototype, we proposed a model of spiral MoTe 2 to optimize collectively the above issues. The conductive atomic force microscopy of an individual spiral reveals that the retentive vertical conduction irrespective of layer thickness benefits from the connected screw dislocation lines between interlayers. Theoretical calculations uncover that the regions near the edge step of the spiral structures more easily form Te vacancies and have lower ΔG H * as extra active sites. A single spiral MoTe 2 ‐based on‐chip microcell was fabricated to extract HER activity and achieved an ultrahigh current density of 3000 mA cm −2 at an overpotential of 0.4 V, which is about two orders of magnitude higher than the exfoliated counterpart. Profoundly, this unusual spiral model will initiate a new pathway for triggering other inert catalytic reactions.

Manipulation of cell–cell interactions via cell surface engineering has potential biomedical applications in tissue engineering and cell therapy. However, manipulation of the comprehensive and multiple intercellular interactions remains a challenge and missing elements. Herein, utilizing a DNA triangular prism (TP) and a branched polymer (BP) as functional modules, we fabricate tunable DNA scaffold networks on the cell surface. The responsiveness of cell–cell recognition, aggregation and dissociation could be modulated by aptamer‐functionalized DNA scaffold networks with high accuracy and specificity. By regulating the DNA scaffold networks coated on the cell surface, controlled intercellular molecular transportation is achieved. Our tunable network provides a simple and extendible strategy which addresses a current need in cell surface engineering to precisely manipulate cell–cell interactions and shows promise as a general tool for controllable cell behavior.
