Dimples can break all symmetries in the law of reflection and make the bouncing of droplets on super‐repellent surfaces non‐specular, reported by Liqiu Wang and co‐workers (article number 2006695), and thus functioning as a “magic” hand to enable various on‐demand droplet manipulations including trapping, shedding, antigravitational transporting, targeted positioning, and coalescing.
In article number 2004487, Abhishek K. Srivastava and co‐workers report the synthesis of quantum rods with a narrow thermally stable luminescence covering the whole visible range by replacing Cd with Zn in one‐pot post‐synthetic development. The quantum rods show high performance in the on‐chip LED configuration covering 122% NTSC in 1931CIE color space with a record‐high luminous efficacy of 115...
In article number 2006709, Tatsuhiko Ohto, Ryo Yamada, Hirokazu Tada, Yoshio Aso, Yutaka Ie, and co‐workers report a tripodal anchor that maintains p‐conjugation through an electrode, anchor, and molecular backbone. Single‐molecular conductance measurements and theoretical calculations reveal that this tripodal anchor molecule shows improved electrical conductance.
Unbiased photoelectrochemical water splitting for the promising InGaN nanorods photoelectrode is highly desirable, but it is practically hindered by the serious recombination of charge carrier in bulk and surface of InGaN nanorods. Herein, an unbiased Z‐scheme InGaN nanorods/Cu2O nanoparticles heterostructured system with boosted interfacial charge transfer is constructed for the first time. The introduced...
Direct hybridization between the π‐orbital of a conjugated molecule and metal electrodes is recognized as a new anchoring strategy to enhance the electrical conductance of single‐molecule junctions. The anchor is expected to maintain direct hybridization between the conjugated molecule and the metal electrodes, and control the orientation of the molecule against the metal electrodes. However, fulfilling...
The bouncing of droplets on super‐repellent surfaces normally resembles specular reflection that obeys the law of reflection. Here, the nonspecular reflection of droplet impingement onto solid surfaces with a dimple for energy‐efficient, omnidirectional droplet transport is reported. With the dimple of the radius being comparable to that of the droplet, all the symmetries in the law of reflection...
Terahertz (THz) biological imaging has attracted intense attention due to its capability of acquiring physicochemical information in a label‐free, noninvasive, and nonionizing manner. However, extending THz imaging to the single‐molecule level remains a challenge, partly due to the weak THz reflectivity of biomolecules with low dielectric constants. Here, the development of graphene‐mediated THz scattering‐type...
Coherent manipulation of light‐matter interactions is pivotal to the advancement of nanophotonics. Conventionally, the non‐resonant optical Stark effect is harnessed for band engineering by intense laser pumping. However, this method is hindered by the transient Stark shifts and the high‐energy laser pumping which, by itself, is precluded as a nanoscale optical source due to light diffraction. As...
The poor electronic conductivity and low intrinsically electrocatalytic activity of most metal–organic frameworks (MOFs) greatly limit their direct applications as oxygen reduction reaction (ORR) electrocatalysts. In this work, it is reported that introduction of linker defects can effectively trigger the ORR activity of leaf‐shaped zeolitic imidazolate framework (ZIF) by increasing the intrinsic...
In article number 2005814, Jiang Li, Huabin Wang, and co‐workers demonstrate the imaging of single protein molecules with a scattering‐type terahertz (THz) scanning near‐field optical microscope, taking advantage of a graphene substrate with high THz reflectivity and atomic smoothness, and a long platinum probe with high scattering ability. This strategy opens new routes to imaging single biomolecules...
This work reports exquisite engineering of catalytic activity of DNA‐templated silver nanoclusters (DNA‐AgNCs) based on unique adsorption phenomena of DNAs on DNA‐AgNCs and reversible transition between double and triple‐stranded DNAs. Four DNA homopolymers exhibit different inhibition effects on the catalytic activity of DNA‐AgNCs, poly adenine (polyA) > poly guanine (polyG) > poly cytosine...
Precise mechanical processing of optical microcrystals involves complex microscale operations viz. moving, bending, lifting, and cutting of crystals. Some of these mechanical operations can be implemented by applying mechanical force at specific points of the crystal to fabricate advanced crystalline optical junctions. Mechanically compliant flexible optical crystals are ideal candidates for the designing...
Achieving strong adsorption and catalytic ability toward polar lithium polysulfide species (LiPSs) of the sulfur host in lithium–sulfur (Li–S) batteries is essential for their electrochemical cyclic stability. Herein, a strategy of “self‐termination of ion exchange” is put forward to synthesize the novel yolk‐shell sulfur host composed of ZnO nanoparticles confined in Co‐doped NiO (CDN) polyhedron...
The precise control of the ice crystal growth during a freezing process is of essential importance for achieving porous cryogels with desired architectures. The present work reports a systematic study on the achievement of multi‐structural cryogels from a binary dispersion containing 50 wt% 2,2,6,6‐tetramethylpiperidin‐1‐oxyl, radical‐mediated oxidized cellulose nanofibers (TOCNs), and 50 wt% graphene...
In the development of solid‐state lithium batteries, solid polymer electrolyte (SPE) has drawn extensive concerns for its thermal and chemical stability, low density, and good processability. Especially SPE efficiently suppresses the formation of lithium dendrite and promotes battery safety. However, most of SPE is derived from the matrix with simple functional group, which suffers from low ionic...
Rechargeable magnesium batteries (RMBs) have been regarded as one of the promising electrochemical energy storage systems to complement Li‐ion batteries owing to the low‐cost and high safety characteristics. However, the various challenges including the sluggish solid‐state diffusion of highly polarizing Mg2+ ions in hosts, and the formation of blocking layers on Mg metal surface have seriously impeded...
Cells are complex machines whose behaviors arise from their internal collection of dynamically interacting organelles, supramolecular complexes, and cytoplasmic chemicals. The current understanding of the nature by which subcellular biology produces cell‐level behaviors is limited by the technological hurdle of measuring the large number (>103) of small‐sized (<1 μm) heterogeneous organelles...
Recently, quantum rods (QRs) have been studied heavily for display and lighting applications. QRs offer serious advantages over the quantum dots such as higher light out‐coupling coefficient, and polarized emission. The QR enhancement films double liquid crystal display efficiency. However, it is still a challenge to synthesize good quality green (λem≈ 520 nm) and blue (λem≈ 465 nm) emitting QRs,...
