Using [Mo(2)S(2)O(2)(H(2)O)(6)](2+) and squarate dianion, we synthesized the thiometalate ring compounds [(Mo(2)S(2)O(2))(x)(OH)(y)(C(4)O(4))(z)(Mo(2)O(8))(o)(H(2)O)(p)](n-), where [x,y,z,o,p,n] = [7,14,2,0,2,4] for 1, [6,8,2,2,4,8] for 2, and [4,6,1,1,0,4] for both 3a and 3b, which are chiral and nonchiral isomers, r…
Nanostructured inverse hexagonal polyoxometalate composite films were cast directly from solution using poly(butadiene-block-2-(dimethylamino)ethyl methacrylate) (PB-b-PDMAEMA) diblock copolymers as structure directing agents for phosphomolybdic acid (H(3)[PMo(12)O(40)], H(3)PMo). H(3)PMo units are selectively incorpo…
The cattail fiber assembly used as a sorbent for the sorption of engine and vegetable oils was investigated. The internal factors governing the oil sorption of cattail fibers were discussed. The analysis for the adsorption mechanism of cattail fiber assembly indicated that the tuft of cattail fibers has a down-like st…
Using the NO2adsorption and Al2O3passivation technique, we improved the thermal stability of hydrogen-terminated diamond field-effect transistors (FETs) and then demonstrated stable operation at 200 °C in a vacuum for the first time. At 200 °C, the drain current IDSof a passivated diamond FET remained constant for at…
Supported Pd nanowire and cuboctahedron catalysts have been synthesized in an ethylene glycol–poly(vinylpyrrolidone)–KBr system using a precipitation–reduction method. KBr plays a critical role in controlling the morphology of Pd: with a variety of relatively low KBr concentrations, Pd nanowires with different lengths…
Abstract The devulcanization reactions of ground tire rubber (GTR) and thermoplastic elastomer (TPE) mixtures performed during the melt‐extrusion process through the induction of high shear stress by increases in the screw rotation speeds and reaction temperatures were investigated in this study. The results show that…
Lightly cross-linked natural rubber (NR, cis-1,4-polyisoprene) was found to be an exceptional cold programmable shape memory polymer (SMP) with strain storage of up to 1000%. These networks are stabilized by strain-induced crystals. Here, we explore the influence of mechanical stress applied perpendicular to the elong…
Abstract Multifunctional high performance functionalized graphene sheets (FGSs) based epoxy nanocomposites were investigated to understand the feasibility that these FGSs‐epoxy nanocomposites can be applied to cryotank composite applications. The FGSs were successfully synthesized from graphite flakes through preparin…
A two-dimensional array of gold optical antennas integrated with a one-dimensional array of gold strips and mirrors is introduced and fabricated. The experimental results show that this design achieves average surface-enhanced Raman scattering (SERS) enhancement factors as high as 1.2 × 10(10) , which is more than two…
This feature article highlights the recent developments of energy transfer processes of Au-nanoparticle-based assemblies. Many recent studies reveal that the energy transfer from dye to Au nanoparticle is a surface energy transfer process as established from 1/d 4 distance dependence. Such distance dependent energy tr…
In mononitrosyl complexes of transition metals two long-lived metastable states corresponding to linkage isomers of the nitrosyl ligand can be induced by irradiation with appropriate wavelengths. Upon irradiation, the N-bound nitrosyl ligand (ground state, GS) turns into two different conformations: isonitrosyl O boun…
Abstract The limitations of clinical chemotherapy are credited primarily to drug resistance. Effective development and screening of new drugs require appropriate in vitro tumor models that resemble the in vivo situation to evaluate drug efficiency and to decrease the use of experimental animals. 3D in vitro model syst…
A new antifog coating made of pullulan is described in this work. The antifog properties are discussed in terms of wettability, surface chemistry/morphology, and by quantitative assessment of the optical properties (haze and transparency) before and after fog formation. The work also presents the results of antifog te…
Beträchtliche Mengen an CO und O2 entstehen bei der photokatalytischen Umwandlung von CO2 an Doppelschichthydroxiden (LDHs) in Wasser (siehe Schema). Eine einfache Mischung von Metallhydroxiden mit derselben Elementzusammensetzung wie das LDH erzeugt nur wenig CO und O2. Als Kohlenstoffquelle in der Reaktion wurde gel…
A pair of orientationally isomeric cyclic stereoblock polylactides (PLAs) possessing head-to-head (HH) and head-to-tail (HT) linkages between the poly( l -lactide) (PLLA) and poly( d -lactide) (PDLA) segments was synthesized through click chemistry and ring-closing metathesis (RCM) of three asymmetrically functionaliz…
Photo- and pH-responsive amphiphilic hyperbranched star copolymers, poly(6-O-methacryloyl-1,2;3,4-di-O-isopropylidene-d-galactopyranose)[poly(2-(N,N-dimethylaminoethyl) methacrylate)-co-poly(1'-(2-methacryloxyethyl)-3',3'-dimethyl-6-nitro-spiro(2H-1-benzo-pyran-2,2'-indoline))](n)s [HPMAlpGP(PDMAEMA-co-PSPMA)(n)], wer…
Transformation of space coordinates can be used as a convenient tool for producing a controlled electromagnetic field pattern. In this paper, using a conformal transformation, the design procedure of a lens antenna with high gain and low sidelobes is presented which can be realized by isotropic graded refractive index…
We describe here light-regulated swelling and degradation features of polymeric nanoparticles that are produced using an inverse microemulsion polymerization method. We demonstrate the phototriggered release characteristics of the nanoparticles by sequestering protein molecules and releasing them using light as a trig…
Abstract The design and development of water dispersible, pH responsive peptide mimic shell cross‐linked magnetic nanocarriers (PMNCs) using a facile soft‐chemical approach is reported. These nanocarriers have an average size about 10 nm, are resistant to protein adsorption in physiological medium, and transform from…
We present an investigation on the large magnetic anisotropy of Fe_{2}P, based on {\it Ab Initio} density-functional theory calculations, with a full potential linear muffin-tin orbital (FP-LMTO) basis. We obtain an uniaxial magnetic anisotropy energy (MAE) of 664 μeV/f.u., which is in decent agreement with experiment…
