N- and H-incorporating Co–B amorphous nanowires were successfully synthesized as superior N2H4 decomposition catalysts for H2 generation via a facile solution plasma process (SPP). A possible mechanism for the formation of the Co–B–N–H nanowires during the SPP is proposed. The incorporation of N and H into the Co–B na…
High-temperature shape memory alloy NiTiHf holds considerable promise for structural applications. An important consideration for these advanced alloys is the determination of the magnitude of the twinning stress. Theoretical stresses for twinning and dislocation slip in NiTiHf martensites are determined. The slip and…
One of the most challenging issues in transparent conductive oxides (TCOs) is to improve their conductivity without compromising transparency. High conductivity in TCO films often comes from a high carrier concentration, which is detrimental to transparency due to free carrier absorption. Here we show that UV laser cr…
The aquatic ecotoxicity testing of nanoparticles is complicated by unstable exposure conditions resulting from various transformation processes of nanoparticles in aqueous suspensions. In this study, we investigated the influence of exposure timing on the algal test response to silver nanoparticles (AgNPs), by reducin…
In this review, a brief overview of the current regulatory science framework pertinent to pharmaceutical crystallization and process characterization is made first. The FDA’s scientific research on pharmaceutical crystallization process understanding and product characterization is then illustrated via several aspects…
Previous studies of the thermal transport in MoS2 are limited to the 0° (zigzag) and 30° (armchair) chiralities. We investigate the anisotropic thermal transport properties of MoS2 nanoribbons with various crystal chiralities by employing the full-band phonon dispersion relations obtained from first-principle calculat…
The purpose of this study was to investigate the mechanical and thermal properties of high-density polyethylene (HDPE) composites reinforced by bamboo pulp fibers (BPF). Using a twin-screw extruder, polymer composites were fabricated using BPF and bamboo flour (BF) as the reinforcement and HDPE as the matrix. Tensile…
2% Al-doped ZnO (AZO) thin films fabricated at 300 °C by pulsed laser deposition (PLD) on amorphous fused silica demonstrated the high quality crystallinity and grain connection, which correlates to the high thermoelectric performance: electrical conductivity σ = 923 S/cm and Seebeck coefficient S = −111 µV/K at 600 K…
Direct and converse magnetoelectric effects are two opposite processes, which were integrated in a model based on equivalent circuit. Following the piezoelectric and magnetostrictive constitutive equations, we obtained magnetic-mechanical-electric equations, and then built a symmetric equivalent circuit about the magn…
The crystallization behaviors of two copolymers of PVDF were studied, and the effect of copolymerized chains on the crystallization behavior was investigated. The results indicated that both copolymers had a lowered crystallization temperature and crystallinity. The crystallization rate was improved by the copolymer w…
The five manganese-containing, Keggin-based tungstosilicates [Mn(II)3(OH)3(H2O)3(A-α-SiW9O34)](7-) (1), [Mn(III)3(OH)3(H2O)3(A-α-SiW9O34)](4-) (2), [Mn(III)3(OH)3(H2O)3(A-β-SiW9O34)](4-) (3), [Mn(III)3Mn(IV)O3(CH3COO)3(A-α-SiW9O34)](6-) (4), and [Mn(III)3Mn(IV)O3(CH3COO)3(A-β-SiW9O34)](6-) (5) were synthesized in aque…
We explored how the visible-light energy absorbed by noble-metal nanoparticles (NPs) is converted to electrons and holes in the semiconductor in a visible-light plasmonic photocatalyst by studying the representative system Ag@AgCl on the basis of density functional calculations and classical electrodynamics calculatio…
We fabricated a perpendicularly magnetized bit pattern media using a hexagonally close-packed auto-assembled anodic alumina template with 100 nm and 50 nm periods by depositing a Co/Pt multilayer to form an ordered array of ferromagnetic nanodots, so-called nanobumps. We used Hall resistance measurements and magnetic…
Common mathematical theories can have profound applications in understanding real materials. The intrinsic connection between aperiodic orders observed in the Fibonacci sequence, Penrose tiling, and quasicrystals is a well-known example. Another example is the self-similarity in fractals and dendrites. From transmissi…
We report the magnetic and magnetotransport properties of (In0.985Nd0.015)2O2.89 thin films grown by pulse laser deposition. The clear magnetization hysteresis loops with the complementary magnetic domain structure reveal the intrinsic room temperature ferromagnetism in the as-prepared films. The strong sp-f exchange…
Abstract Five single‐side organic decorated Anderson‐type molybdoaluminates have been synthesized from the reaction of the Na 3 (H 2 O) 6 [Al(OH) 6 Mo 6 O 18 ] · 2H 2 O cluster and RC(CH 2 OH) 3 ligands [R = CH 2 OH, NH 2 , CH 2 CH 3 , NHCH 2 COOH, CH 2 OCH 2 C(CH 2 OH) 3 ], followed by the addition of TBA · Br {TBA =…
Applications of implantable bioelectronics for analytical and curative purposes are currently limited by their poor long-term biofunctionality in physiological media and nonspecific interactions with biomolecules. In an attempt to prolong in vivo functionality, recent advances in surface modifications have demonstrate…
The origin of b 2 -type bands in the surface-enhanced Raman scattering (SERS) of 4-nitrobenzenethiol (4-NBT) and 4-aminobenzenethiol (4-ABT) has recently been debated because these bands are very similar to those attributed to a photoreaction product such as 4,4′-dimercaptoazobenzene (4,4′-DMAB). To resolve the debate…
A coumarin-modified pyrimidine nucleoside (1) has been synthesized using a Cu(I)-catalyzed click reaction and incorporated into oligodeoxynucleotides (ODNs). Interstrand cross-links are produced upon irradiation of ODNs containing 1 at 350 nm. Cross-linking occurs through a [2+2] cycloaddition reaction with the opposi…
The multilayer WS2 nanosheets prepared from WO3 nanowires exhibit strong ferromagnetic behavior with saturation magnetization (MS) of 0.0058 emu/g and coercive field (HC) of 92 Oe at room temperature. By decreasing the temperature down to 3 K the Hc is increased up to 1115 Oe, revealing the existence of long-range mag…
