Several species of Magnoliaceae and Annonaceae are used in Traditional Chinese Medicine. (-)-Anonaine, isolated from several species of Magnoliaceae and Annonaceae, presents antiplasmodial, antibacterial, antifungal, antioxidation, anticancer, antidepression, and vasorelaxant activity. This article provides an overvie…
A high performance, stretchable UV sensor array was fabricated based on an active matrix (AM) device that combined field effect transistors of SWCNTs and SnO2 nanowires. The AM devices provided spatial UV sensing via the individual sensors in the array. SnO2 NW UV sensors showed an average photosensitivity of ∼10(5) a…
We study the dynamic effects in the double graphene-layer (GL) structures with the resonant-tunnelling (RT) and the negative differential inter-GL conductivity. Using the developed model, which accounts for the excitation of self-consistent oscillations of the electron and hole densities and the ac electric field betw…
In a previous work by our group, a new kind of ilmenite oxygen carrier, namely, natural ilmenite particles impregnated with foreign ions (K +, Na +, or Ca 2+ ), was reported as having a promoted reactivity. The objective of this work was to investigate the detailed reduction kinetics of the new foreign-ion-promoted il…
The mechanism of emergence of robust quantum criticality in Yb- and Ce-based heavy electron systems under pressure is analyzed theoretically. By constructing a minimal model for quasicrystal Yb15Al34Au51 and its approximant, we show that quantum critical points of the first-order valence transition of Yb appear in the…
In studying the molecular basis for the potent immune activity of previously described gamma and delta inulin particles and to assist in production of inulin adjuvants under Good Manufacturing Practice, we identified five new inulin isoforms, bringing the total to seven plus the amorphous form. These isoforms comprise…
In the search for a highly active and selective heterogenized metathesis catalyst, we systematically varied the pore geometry and size of various silica-based mesoporous (i.e., MCM-41, MCM-48, and SBA-15) and microporous (ZSM-5 and MWW) versus macroporous materials (D11-10 and Aerosil 200), besides other process param…
A new family of heterometal-organic frameworks has been prepared by two synthesis strategies, in which IFMC-26 and IFMC-27 are constructed by self-assembly and IFMC-28 is obtained by stepwise synthesis based on the metalloligand (IFMC=Institute of Functional Material Chemistry). IFMC-26 is a (3,6)-connected net and IF…
Standard states are utilized to compare thermodynamic data obtained from different experiments and calculations, and this ability to compare thermodynamic data plays an important role in science and society. For molecules adsorbed on surfaces, there are currently no universally accepted standard states. Here, standard…
We report on the characterization of thin-film near and short wavelength infrared absorbers comprised of carbon nanotubes dispersed in a polymer. Charged nanodiamond particles are used to effectively and uniformly disperse the carbon nanotubes in the polymer matrix, leading to a very homogenous film. Using this new te…
A new dinitrogen adduct of a homoleptic uranium tris(siloxide) complex, [U{OSi(Mes) 3 } 3 ] 2 (μ-η 2:η 2 -N 2 ), is reported. Synthesis of the 15 N-labeled isotopomer and Raman spectroscopy confirm the reductive activation of N 2 to a (N 2 ) 2– dianion. The 15 N NMR shift of the 15 N 2 -labeled isotopomer is also repo…
Molecular dynamics simulations of Lennard-Jones particles have been performed to study the evaporation behavior of nanodroplets on heated substrates. The influence of the liquid-substrate interaction strength on the evaporation properties was addressed. Our results show that, during the temperature-raising evaporation…
We have developed an active-space decomposition strategy for molecular dimers that allows for the efficient computation of the dimer's complete-active-space wavefunction while only constructing the monomers' active-space wavefunctions. Dimer states are formed from linear combinations of direct products of localized or…
Epitaxial growth of topological insulator bismuth telluride by molecular beam epitaxy onto BaF 2 (111) substrates is studied using Bi 2 Te 3 and Te as source materials. By changing the beam flux composition, different stoichiometric phases are obtained, resulting in high quality Bi 2 Te 3 and Bi 1 Te 1 epilayers as sh…
This study focuses on clarifying the strong interaction existing between extended graphitic domains of ordered carbonaceous materials such as multiwalled carbon nanotubes and platinum nanoparticles. This interaction results from the heterogeneous nucleation of platinum nanoparticles onto the carbon support. The metal…
We demonstrate feedback-optimized focusing of spatially coherent polychromatic light after transmission through strongly scattering media, and describe the relationship between optimized focus intensity and initial far-field speckle contrast. Optimization is performed using a MEMS spatial light modulator with camera-b…
A burning question in the emerging field of spin-orbit driven insulating iridates, such as Na${}_{2}$IrO${}_{3}$ and Li${}_{2}$IrO${}_{3}$, is whether the observed insulating state should be classified as a Mott-Hubbard insulator derived from a half-filled relativistic ${j}_{\mathrm{eff}}=1/2$ band or as a band insula…
The photodriven accumulation of two oxidative equivalents at a single site was investigated on TiO2 coloaded with a ruthenium polypyridyl chromophore [Ru(bpy)2((4,4'-(OH)2PO)2bpy)](2+) (Ru(II)P(2+), bpy = 2,2'-bipyridine, ((OH)2PO)2-bpy = 2,2'-bipyridine-4,4'-diyldiphosphonic acid) and a water oxidation catalyst [Ru(M…
Stable biofouling resistance is significant for general filtration requirements, especially for the improvement of membrane lifetime. A systematic group of hyper-brush PEGylated diblock copolymers containing poly(ethylene glycol) methacrylate (PEGMA) and polystyrene (PS) was synthesized using an atom transfer radical…
In recent years, many nanomaterials-assisted chemiluminescence (CL) systems have been developed to improve the sensitivity and to expand the scope of their analytical applications. In these new systems, nanomaterials participate in CL reactions as catalysts, labels, reductants, luminophors, or energy acceptors. This r…
