A polymer-dispersed azobenzene and GO nanocomposite film was fabricated with shape memory polyurethane as a matrix.
Capacitive deionization (CDI) has shown great promise in desalinating salt water; however, conventional CDI electrode materials suffer from low specific capacity and charge efficiency owing to the co-ion expulsion effect. Herein, using expanded MoS2 nanosheets supported by reduced graphene oxide (MoS2/rGO) as intercalation electrode, we develop a hybrid system that shows battery-like behavior can reversibly store cations through mechanism. The incorporation of rGO composite not only affords...
Reaction of the chiral ligand (−)-4,5-pinenepyridyl-2-pyrazine (L) with Ln(hfac)3·2H2O precursors [hfac− = 1,1,1,5,5,5-hexafluoroacetylacetonate, Ln Sm3+ (1), Eu3+ (2), Tb3+ (3) and Dy3+ (4)] in methanol solution led to formation four noncentrosymmetric lanthanide complexes general formula [Ln(hfac)3L]n·H2O. The single-crystal X-ray diffraction analyses revealed that they are isostructural take a one-dimensional (1D) chain structure based on Ln(hfac)3L repeating units, which nine-coordinate...
The exploitation of high-performance third-order nonlinear optical (NLO) materials that have a favorable limit (OL) threshold is essential due to rise in the application ultra-intense lasers. In this study, Cu-based MOF (denoted as Cu-bpy) was synthesized, and its NLO OL properties were investigated using Z-scan technique with nanosecond laser pulse excitation set at 532 nm. Cu-bpy exhibits typical rate reverse saturable absorption (RSA) coefficient 100 cm GW−1 0.75 J cm−2 (at concentration...
Two pyrenyl Schiff base derivatives with π conjugated structures (B2 and B3) were designed synthesized. Then, B2 B3 added into polyurethane to obtain doped bonded nonlinear optical materials (B2/PU B3/PU), respectively. The synthesized B2, B3, tested by a nanosecond (ns) picosecond (ps) pulse Z-scan at 532 nm wavelength. Due the two-photon absorption-induced excited state absorption (TPA-ESA), show reverse saturable (RSA). From quantum chemistry calculation, it can be concluded that RSA of...
The coordination possibilities of flexible heteroalicyclic ligands with transition metals have been explored. Five CuII, MnII, and CdII polymers the fully deprotonated tetrahydrofuran-2,3,4,5-tetracarboxylate (L) ligand were synthesized characterized, sometimes incorporating different auxiliary ligands: {[Cu2(L)(H2O)](H2O)1.42}∞ (1), {[Cu2(L)(2bpy)(H2O)2](H2O)2}∞ (2), {[Cu2(L)(phen)(H2O)2](H2O)1.5(CH3OH)0.25}∞ (3), {[Mn2(L)(phen)2(H2O)](H2O)2}∞ (4), {[Cd2(L)(phen)2(H2O)](H2O)2}∞ (5) (2bpy =...
To systematically explore the influence of pyridyl N-donor spatial positions benzotriazol-1-yl-based tectons on structural assemblies coordination polymers, three closely related ligands, 1-(2-pyridylmethyl)-1H-benzotriazole (2-pbt), 1-(4-pyridylmethyl)-1H-benzotriazole (4-pbt), and 1-(3-pyridylmethyl)-1H-benzotriazole (3-pbt), were designed prepared. Their reactions with CuI under hydrothermal conditions afforded new copper(I)-iodide namely, [CuI(2-pbt)]∞ (1), [Cu2I2(4-pbt)]∞ (2),...

The Rh(III)-catalyzed indole C4-H bond addition to nitroalkenes is disclosed under mild and redox-neutral reaction conditions, offering straightforward access various 4-(2-nitroalkyl)indoles (34 examples) with excellent chemo- regioselectivity. Furthermore, late-stage diversifications mechanistic studies were also performed.
Repeated Unit Cell (RUC) is a useful tool in micromechanical analysis of composites using Displacement-based Finite Element (DFE) method, and merely applying Periodic Displacement Boundary Conditions (PDBCs) to RUC almost standard practice conduct such analysis. Two basic questions arising from this are whether Traction (PTBCs, also known as traction continuity conditions) guaranteed the solution independent selection RUCs. This paper presents theoretical aspects tackle these questions,...
A proper operating temperature range and an acceptable uniformity are extremely essential for the efficient safe operation of Li-ion battery array, which is important power source space stations. The single-phase fluid loop one effective approaches thermal management battery. Due to limitation that once structure cold plate (CP) determined, it difficult adjust cooling ability different locations CP dynamically, this may lead a large difference array attached CP. This paper presents...
