A small-molecule-based ternary memory device is used in transient thermal-probing electronics. The PYAE-based memory device is featured with three electrical transition signals ("0," "1," and "2"), while the heated PYAE-based device is only characterized by two electrical transition signals ("1" and "2"). The organic…
Abstract An environmentally friendly (“green”), H 2 -generation system was developed that involved hydrolytic oxidation of inexpensive organosilanes as hydrogen storage materials with newly developed heterogeneous gold nanoparticle catalysts. The gold catalyst functioned well at ambient temperature under aerobic condi…
Multicolored electrochromism has been achieved in single-layer electrochromic devices at a fixed potential employing benzodipyrrolidone based ambipolar electrochromes.
This paper illustrates structure–property relationship of organic conjugated molecules in forming NIR-absorbing organic donor/acceptor charge-transfer complex at ground state.
) graphene-poly(dopamine) modified carbon nanotube composite aerogels that needed no additional reducing agents during the forming process is reported herein. The composite aerogels exhibited highly repeatable compressibility and superior electrical conductivity, and thus will have an important application value in st…
Biological small-angle X-ray scattering (SAXS) is an increasingly popular technique used to obtain nanoscale structural information on macromolecules in solution. However, radiation damage to the samples limits the amount of useful data that can be collected from a single sample. In contrast to the extensive analytica…
Abstract Non‐oxidative methane conversion over Fe©SiO 2 catalyst was studied for the first time in a hydrogen (H 2 ) permeable tubular membrane reactor. The membrane reactor is composed of a mixed ionic–electronic SrCe 0.7 Zr 0.2 Eu 0.1 O 3−δ thin film (≈20 μm) supported on the outer surface of a one‐end capped porous…
Solvent plays a vital role in the syntheses, purifications, and broad applications of upconversion nanoparticles (UCNPs). In this work, the effect of various dispersive solvents, including single solvents and mixed solvents, on the luminescence properties of NaYF 4:Yb 3+, Er 3+ UCNPs was studied systematically. The di…
Abstract Identifying key factors that govern the in vivo behavior of nanomaterials is critical to the clinical translation of nanomedicines. Overshadowed by size‐, shape‐, and surface‐chemistry effects, the impact of the particle core density on clearance and tumor targeting of inorganic nanoparticles (NPs) remains la…
Twelve novel dinuclear ZnII–LnIII complexes of general formula [Zn(μ-L)(μ-OAc)Ln(NO3)2] (LnIII = Y (1), Pr (2), Nd (3), Sm (4), Eu (5), Gd (6), Tb (7), Dy (8), Ho (9), Er (10), Tm (11), Yb (12)) have been prepared from the symmetric compartmental Mannich base ligand N,N′-dimethyl-N,N′-bis(2-hydroxy-3-methoxy-5-methylb…
ABSTRACT A type of quick water‐responsive shape memory hybrids is fabricated by introducing cellulose nanofibrous mats as the filler in a polymeric matrix. Cellulose nanofibrous mats are obtained through hydrolyzing electrospun cellulose acetate (CA) nanofibers, then casted in thermoplastic polyurethane (TPU) solution…
We report the growth of large-area monolayer MoS2(1−x)Se2x alloys with controlled morphologies using a low-pressure chemical vapor deposition (CVD) method. MoS2(1−x)Se2x alloys with different morphologies, created using the same growth time, have been observed by controlling the gaseous MoO3 precursor on substrates pl…
Abstract Hyper‐crosslinked polymers (HCPs) are promising materials for gas capture and storage, but high cost and complicated preparation limit their practical application. In this paper, a new type of HCPs (CTHPs) was synthesized through a one‐step mild Friedel–Crafts reaction with low‐cost coal tar as the starting m…
We introduce a practical dielectric metasurface design for microwave frequencies. The metasurface is made of an array of dielectric resonators held together by dielectric connections thus avoiding the need of a mechanical support in the form of a dielectric slab and the spurious multiple reflections that such a slab w…
Abstract Photoelectrochemical (PEC) water splitting using semiconductor materials as light absorbers have been extensively studied. Several semiconducting materials have been proposed, such as TiO 2 , ZnO, and GaN. Because the efficiency of PEC water splitting is dependent on visible light absorption, the ability to t…
Perfect spin filtering is an important issue in spintronics. Although such spin filtering showing giant magnetoresistance was suggested using graphene nanoribbons (GNRs) on both ends of which strong magnetic fields were applied, electric field controlled spin filtering is more interesting due to much easier precise co…
Abstract As a strongly correlated metal oxide, VO 2 inspires several highly technological applications. The challenging reliable wafer-scale synthesis of high quality polycrystalline VO 2 coatings is demonstrated on 4” Si taking advantage of the oxidative sintering of chemically vapor deposited VO 2 films. This approa…
When we cool down a liquid below the melting temperature, it can either crystallize or become supercooled, and then form a disordered solid called glass. Understanding what makes a liquid to crystallize readily in one case and form a stable glass in another is a fundamental problem in science and technology. Here we s…
This article presents a detailed thermodynamic case study based on the Willem-Alexander Centrale (WAC) power plant in the Netherlands towards retrofitting SOFCs in existing IGCC power plants with a focus on near future implementation. Two systems with high percentage (up to 70%) biomass co-gasification (based on previ…
The ability to fabricate lanthanide-doped upconversion nanocrystals (UCNCs) with tailored size and emission profile has fuelled their uses in a broad spectrum of biological applications. Yet, limited success has been met in the preparation of sub-6 nm UCNCs with efficient upconversion photoluminescence (UCPL), which e…
