Abstract Light is usually confined in photonic structures with a band gap or relatively high refractive index for broad scientific and technical applications. Here, a light confinement mechanism is proposed based on the photonic bound state in the continuum (BIC). In a low‐refractive‐index waveguide on a high‐refracti…
Conjugated microporous polymer nanotubes (CMPNs) were synthesized and employed as a platform for investigation of CO 2 and I 2 adsorption. A high adsorption capacity of up to 208 wt% for reversible I 2 capture was achieved.
We report the successful incorporation of bifunctional (acid/base) catalytic sites in the crystalline organocatalytic porous COF (2,3-DhaTph). Due to the presence of acidic (catachol) and basic (porphyrin) sites, 2,3-DhaTph shows significant selectivity, reusability, and excellent ability to perform the cascade reacti…
The structural arrangement of amino acid residues in a native enzyme provides a blueprint for the design of artificial enzymes. One challenge of mimicking the catalytic center of a native enzyme is how to arrange the essential amino acid residues in an appropriate position. In this study, we designed an artificial hyd…
The optical and electronic properties of quantum dots (QDs), which are drastically affected by their size, have a major impact on their performance in devices such as solar cells. We now report the size-dependent solar cell performance for CuInS 2 QDs capped with 1-dodecanethiol. Pyramidal shaped CuInS 2 QDs with diam…
We systematically investigated the geometric, electronic and thermoelectric (TE) properties of bulk black phosphorus (BP) under strain. The hinge-like structure of BP brings unusual mechanical responses such as anisotropic Young's modulus and negative Poisson's ratio. A sensitive electronic structure of BP makes it tr…
We study nanoindentation and scratching of graphene-covered Pt(111) surfaces in computer simulations and experiments. We find elastic response at low load, plastic deformation of Pt below the graphene at intermediate load, and eventual rupture of the graphene at high load. Friction remains low in the first two regimes…
A robust strategy is explored to graft poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) brushes on two-dimensional vanadium carbide (V2C) materials through self-initiated photografting and photopolymerization (SIPGP). CO2 and temperature dual-responsive properties of PDMAEMA allow this hybrid to be used as a smart…
The review summarizes recent oxidation and hydrogenation strategies catalyzed by g-C 3 N 4 based systems.
Abstract With the increasing environmental concerns such as sustainability and end-of-life disposal challenges, materials derived from renewable resources such as nanocellulose have been strongly advocated as potential replacements for packaging materials. Nanocellulose can be extracted from various plant resources th…
Fermi systems in the cross-over regime between weakly coupled Bardeen-Cooper-Schrieffer (BCS) and strongly coupled Bose-Einstein-condensate (BEC) limits are among the most fascinating objects to study the behavior of an assembly of strongly interacting particles. The physics of this cross-over has been of considerable…
Nucleic acid-functionalized polyacrylamide chains that are cooperatively cross-linked by i-motif and nucleic acid duplex units yield, at pH 5.0, DNA hydrogels exhibiting shape-memory properties. Separation of the i-motif units at pH 8.0 dissolves the hydrogel into a quasi-liquid phase. The residual duplex units provid…
Large protein-sized synthetic supramolecular architecture is rare and certainly has not yet achieved the structural and functional complexity of biomolecules. As multiple, identical copies of a few building blocks are repetitively used, a highly symmetrical architecture results with limitations in function. In marked…
Perovskite solid solution ceramics of (1 − x ) BaTiO 3 – x Bi ( Mg 2/3 Nb 1/3 ) O 3 ( BT – BMN ) ( x = 0.05–0.2) were synthesized by solid‐state reaction technique. The results show that the BMN addition could lower the sintering temperature of BT ‐based ceramics. X ‐ray diffraction results reveal a pure perovskite st…
High-resolution screen printing of pristine graphene is introduced for the rapid fabrication of conductive lines on flexible substrates. Well-defined silicon stencils and viscosity-controlled inks facilitate the preparation of high-quality graphene patterns as narrow as 40 μm. This strategy provides an efficient metho…
Fluorescent biosensors are powerful analytical tools for studying biological events in living systems. Luminescent materials with aggregation-induced emission (AIE) attributes have attracted much research interest and have been identified as a novel class of luminogens to develop fluorescent turn-on biosensors with su…
Nel presente lavoro si è voluto effettuare uno studio relativo a leghe e polimeri a memoria di forma (SMA, SMP), con lo scopo di realizzare un attuatore ibrido lineare e valutarne la possibilità di una concreta applicazione. Il primo passo è stata la definizione dei componenti: un set di molle SMA, ognuna caratterizza…
La présente étude a pour objectif l'obtention d'une équation donnant la vitesse globale de la réaction (activité catalytique) de la réaction NH3-SCR sur des catalyseurs du type V2O5/WO3/TiO2 (a) utilisable pour des conditions expérimentales (pressions partielles des réactifs et des constituants du mélange gazeux et te…
L’objectif de ce travail a été de quantifier l’effet de propriétés d’interface sur la taille de bulle de mousses produites par battage en continu, et d’identifier de manière plus précise les mécanismes impliqués dans la structuration des mousses. Les interactions avec certaines variables de procédé - vitesse et pressi…
