A strategy is shown to fabricate highly organized mesoporous anatase films exhibiting favorable properties for photocatalysis and photovoltaic applications by the hydrolysis/condensation of TiCl 4 in the presence of PHB−PEO block copolymer templates. Dipcoating for evaporation-induced-self-assembly followed by a strai…
This paper briefly describes sodium sulfur (NAS) battery development with emphasis on the program to establish the technology for the use of a β‐alumina solid electrolyte. Since the mid‐1980s, NGK INSULATORS, LTD. (NGK) and the Tokyo Electric Power Company (TEPCO) have jointly conducted the NAS battery development pro…
Substantial effort is being invested by the bioengineering community to develop biodegradable polymer scaffolds suitable for tissue-engineering applications. An ideal scaffold should mimic the structural and purposeful profile of materials found in the natural extracellular matrix (ECM) architecture. To accomplish thi…
A critical review of three classic papers by B Hopkinson, RM Davies, and H Kolsky, and the state-of-the-art in Hopkinson bar experimental techniques is presented. The validity and applicability of the assumption made in the 1D Hopkinson bar theory are discussed. Fundamentals of the Hopkinson bar experimental procedure…
We combine confocal microscopy using supercontinuum laser illumination and an interferometric detection technique to identify single nanoparticles of diameter below 10 nm. Spectral analysis of the signal allows us to record the plasmon resonance of a single nanoparticle. Our results hold great promise for fundamental…
Abstract Strong interfacial bonding and homogenous dispersion have been found to be necessary conditions to take full advantage of the extraordinary properties of nanotubes for reinforcement of composites. We have developed a fully integrated nanotube composite material through the use of functionalized single‐walled…
The term antimicrobialpackaging encompasses any packaging technique(s) used to control microbial growth in a food product. These include packaging materials and edible films and coatings that contain antimicrobial agents and also techniques that modify the atmosphere within the package. In recent years, antimicrobial…
Tissue engineering is a rapidly evolving discipline that seeks to repair, replace, or regenerate specific tissues or organs by translating fundamental knowledge in physics, chemistry, and biology into practical and effective materials, devices, systems, and clinical strategies. Stem cells and progenitors that are capa…
STRIDE is a software tool for secondary structure assignment from atomic resolution protein structures. It implements a knowledge-based algorithm that makes combined use of hydrogen bond energy and statistically derived backbone torsional angle information and is optimized to return resulting assignments in maximal ag…
MolProbity is a general-purpose web service offering quality validation for three-dimensional (3D) structures of proteins, nucleic acids and complexes. It provides detailed all-atom contact analysis of any steric problems within the molecules and can calculate and display the H-bond and van der Waals contacts in the i…
Soapstock from the neutralisation of rice bran oil was characterised through the most important parameters with direct influence on the acidulation process. A central composite rotational experimental design of two levels was used. The responses of the trials were γ -oryzanol concentration in the acid oil and process…
Rubidium metaborate, Rb3B3O6, was obtained by the reaction of Rb2CO3 and BN using a radiofrequency furnace at a maximum reaction temperature of 1173 K. The crystal structure has been determined by single-crystal X-ray diffraction. The space group is R3c, with all atoms positioned on a twofold axis (Wyckoff site 18e).…
The service life and reliability of machines for basic soil cultivation is mainly affected by abrasive wear. The working tools of these machines are mostly made of steel. The paper deals with the possibility of manufacturing ploughshares and reversible points of austempered ductile iron (ADI). The authors examine the…
The Auger signal and the intensity of elastically backscattered electrons were measured as a function of the incidence angle of the primary electron beam to find the crystalline structure of ultrathin Ag layers on the $\mathrm{Cu}(111)$ surface. Experimental profiles were compared with theoretical data obtained with t…
This paper presents a numerical analysis of losses generated in the tank-wall surrounding the high-current bushings of pad-mounted transformers using a three-dimensional (3-D) finite-element approach. Two cases are analyzed to study the impact of inserting small plates of different geometry (located near the high-curr…
Neumann-Good's parallel strip model (J. Colloid Interface Sci. 1972, 38, 341) was used to analyze the contact angle hysteresis for a liquid on a heterogeneous surface composed of alternatively aligned horizontal apolar (theta = 70 degrees ) and polar (theta = 0 degree ) strips. The critical size of the strip width, be…
The aggregation process of meso -tetra(4-aminosulfonylphenyl)porphyrin (PC 0 ), of butyl and dodecyl derivatives (PC 4 and PC 12, respectively) in the presence of aerosol-OT (AOT) reversed micelles with different values of ω 0 = [water]/[AOT] was investigated using steady-state extinction, fluorescence, and resonance…
Refraction of a slow surface electromagnetic wave (magnetostatic wave) at the boundary between ferrite and ferrite-insulator-metal media is investigated experimentally and theoretically. The boundary is created in an yttrium iron garnet film by placing a metal plate at a certain distance from its surface. The refracti…
Nonlinear transmission of single-wall carbon nanotubes in heavy water at a wavelength of 1.54 μm and self-mode locking in a Er3+ : glass laser obtained using a passive nanotube switch, Nikolai N Il'ichev, Elena D Obraztsova, Sergei V Garnov, Svetlana E Mosaleva
The synthesis of a series of octopolar 1,3,5-tris(ethynylphenyl)benzenes via Sonogashira coupling is described, varying the substituents on both the central benzene core as well as the acetylenic periphery. In particular, systems bearing an electron-rich core and an electron-poor periphery are obtained that display ad…
