ABSTRACT In order to investigate whether the particle sizes of inorganic additives in polymer have an influence on the flame‐retardant and other properties of the polymer, five types of Mg3Al–CO3 layered double hydroxide (LDHs) with particle diameters of 80–100, 200–350, 500–550, 550–600, and 700–900 nm were synthesiz…
Abstract Compared with MoS 2 and WS 2 , selenide analogs have narrower band gaps and higher electron mobilities, which make them more applicable to real electrical devices. In addition, few-layer metal selenides have higher electrical conductivity, carrier mobility and light absorption than the corresponding monolayer…
Two spiroannulated molecular structures with dithiafulvenyl units functionalized at the 2,2',7,7'- (SFX-DTF1) and 2,3',6,'7- (SFX-DTF2) positions of a spiro[fluorene-9,9'-xanthene] core were synthesized. Studies revealed the hole mobility was significantly influenced by the dithiafulvenyl functionalized positions in t…
Graphene gratings provide a promising route towards the miniaturization of THz metasurfaces and other photonic devices, chiefly due to remarkable optical properties of graphene. In this paper, we propose novel graphene nanostructures for passive and active control of the polarization state of THz waves. The proposed d…
Through high-resolution electron microscopy, the surface structure of barium titanate and strontium titanate nanoparticles are found to be terminated by a TiO 2 double layer. These results confirm prior observations of TiO 2 -rich surface reconstructions on strontium titanate nanoparticles made hydrothermally at high…
co-doped fluoroborate glass phosphors had potential application in white LED.
This review summarizes dielectric studies and related experiments on ferroelectrics and multiferroics about which there has been considerable controversy in the literature, sometimes at unusually impolite and unprofessional levels. In addition it focuses attention on a new anomalous phenomenon – that of ferroelectric…
A new biocatalyst in the form of Komagataeibacter xylinum B-12429 cells immobilized in poly(vinyl alcohol) cryogel for production of bacterial cellulose was demonstrated. Normally, the increased bacteria concentration causes an enlarged bacterial cellulose synthesis while cells push the polysaccharide out to pack them…
Organic–inorganic coating has been desirable for practical applications in electrochemistry and analytical science. Up to this investigation, a report of a “flowerlike” structure made from organic components has been rarely reported. Here, we proposed a novel strategy to fabricate the flowerlike hybrid coating through…
Internally contracted multireference coupled cluster (icMRCC) theory is embedded within multireference perturbation theory (MRPT) to calculate energy differences in large strongly correlated systems. The embedding scheme is based on partitioning the orbital spaces of a complete active space self-consistent field (CASS…
The controllable manipulation of materials properties has always attracted broad interests since there exists the possibility to identify the relationship between different electronic states, and even discover new states. Here we report the electrochemical intercalation of cetyltrimethylammonium (CTA + ) into 2H–TaS 2…
Abstract A rod‐like hollow cobalt tungstate/non‐stoichiometric cobalt sulfide (CoWO4/Co1−xS) hybrid is successfully grown in situ on nickel foam through a simple two‐step hydrothermal process. Owing to the unique hollow structure, the as‐synthesized CoWO4/Co1−xS hybrid electrode possesses a large surface area and deli…
Two robust metal–organic frameworks (MOFs), {H 4 [Ni(π-H 2 O) 2 ] 2 [Ni(rt-H 2 O) 2 ] 8 Ni 4 (Tri) 24 }[V IV W 12 O 40 ] 2 ·24H 2 O ( 1 ) and {H[Ni(π-O) 2 ] 2 [Ni(rt-H 2 O) 2 ] 8 Ni 4 (Tri) 24 }[V IV W 10 V V 2 O 40 V 2 ][V IV W 9 V V 3 O 40 V IV 2 ]·24H 2 O ( 2 ) (Tri = 1,2,4-triazole), composed of polyoxometalates (…
Abstract Structurally simple chalcone derivatives 1–2 are prepared and their diversified emission behaviors are deeply investigated. Two polymorphs (1G: λem = 536 nm, Φf = 0.08, τ = 1.81 ns; 1O: λem = 573 nm, Φf = 0.19, τ = 10.82 ns) with distinctively different emission behaviors are constructed by finely controlling…
The growing consumption of tender coconut water in Brazil has resulted in a generation of green husk, which in turn has led to pollution, as it takes eight to ten years to degrade. With the objective of finding applications for these fibers, the characterization of their chemical composition, tensile properties, and s…
The authors discuss a fast memory application based on thermal hysteresis in a magnetically driven superconducting quantum interference device (SQUID). Their theoretical exploration of the coherent thermal transport in an inductive temperature-biased SQUID reveals appreciable bistability of electrode temperature in th…
The electronic properties of titanium(IV) sulfide (TiS 2 ) have been scrutinized for many decades due to its strong tendency toward nonstoichiometry with either titanium excess or sulfur deficiency in its crystal structure. Here, the systematic solid-state transformation of TiS 3 to TiS 2– x nanobelts as a means to co…
The inherent properties of a single atomic carbon layer in graphene offer opportunities for the creation of catalytically active centers tailored on a molecular level on a support with high thermal stability and very high specific surface area. We demonstrate that organization of the two-dimensional system of the carb…
A novel design of spoof surface plasmon polariton (SSPP) planar antenna is proposed based on the wave vector modulation of transmissive phase gradient metasurface (TPGM). The antenna consists of TPGM placed a certain distance above SSPP guided wave structure, exhibiting the directional radiation property according to…
ABSTRACT This study evaluated the thermal, morphological, chemical, and mechanical properties of virgin and recycled polystyrene. The recycling process was carried out by dissolution of polystyrene (extruded and crystal) in ethyl acetate, followed by two processes for solvent removal: vaporization by direct contact wi…
