The amorphous LaMoO material was investigated as a sulfur-tolerant anode for solid oxide fuel cells (SOFCs), which was obtained by reducing the ionic conductor in the SOFC anodic atmosphere. The performance of the amorphous anode was assessed using the electrolyte-supported cells with a thick disk as the electrolyte a…
The preparation of a new conjugated polymer with a low band gap of approximately 0.5 eV has been accomplished via the electropolymerization of acenaphto[1,2-b]thieno[3,4-e]pyrazine.
Changes in morphology, surface reactivity and surface-enhancement of Raman scattering induced by modification of borate-stabilized Ag nanoparticles by adsorbed chlorides have been explored using TEM, EDX analysis and SERS spectra of probing adsorbate 2,2'-bipyridine (bpy) excited at 514.5 nm and evaluated by factor an…
Under ultrasonic radiation, 2′-deoxyadenosine, having an octyl hydrocarbon tail with a urea linker, gelates water. Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) results show that the molecular assembly depends on the whether heat or ultrasound is the energy source.
Diffusion barrier performances of atomic layer deposited (ALD)-Ru thin films between Cu and Si were improved with the use of an underlying 2 nm thick ALD-TaCN interlayer as diffusion barrier for the direct plating of Cu. Ru was deposited by a sequential supply of bis (ethylcyclopentadienyl)ruthenium and plasma and TaC…
Ultrathin Ru–N and Ru–Ta–N films ( in thickness) deposited by reactive sputtering are applied as a diffusion barrier in the Cu/barrier/ systems. After film deposition, the samples are tested before and after annealing at in vacuum for . The sheet resistance examined by four-point probe appraises that the Ru–Ta–N barri…
Coaxial electrospinning is a new technique to fabricate continuous composite ultrafine fibers with core/shell structure, which has a broad application perspective in the biomedical field. In this study, ultrafine fibrous membranes of core/shell poly(vinyl pyrrolidone)/poly(L-lactide-co-epsilon-caprolactone) (PVP/PLCL)…
Alkyl (S)-lactate and alkyl (S,S)-lactyllactate were rapidly and conveniently synthesized from L-lactide using Group 1 and 2 metal complexes as catalyst in alcohol.
A new series of isophthalate-based electrochromic materials were prepared. The functional groups at the 5-position of isophthalate have a significant influence on the observed color. In particular, an electrochemically active nitro group induced a multi-color display, indicating that further electrochromic properties…
This paper provides an overview of the development and applications of plasmonics-active nanoprobes in biomedical diagnostics. Specific examples of detection techniques using surface-enhanced Raman scattering are presented to illustrate the usefulness and potential of the plasmonics nanoprobes for gene detection and n…
Core-shell type of architecture revealed the subtle competition between liquid-crystalline ordering and block copolymer (BCP) self-assembly in a rod-coil BCP system.
Biomimetic synthesis is emerging as an advantageous alternative to the harsh synthetic conditions traditionally used in metal oxide syntheses techniques. Silaffins, proteins from the C. fusiformis diatom, form silica in an aqueous environment under benign conditions. Amine terminated PAMAM and PPI dendrimers are effec…
In this study, the preparation of some novel metallophthalocyanine (MPcs) complexes substituted with octakis(mercaptopropylisobutyl-POSS) functional group was achieved. By the reaction of [1-(3-mercapto)propyl-3,5,7,9,11,13,15-isobutylpentacyclo[9.5.1.1(3,9).1(5,15).1(7,13)]octasiloxane 1 with 4,5-dichloro-1,2-dicyano…
Under UV irradiation in acetonitrile, acyl(allyl)silanes undergo an intramolecular (2+2) cycloaddition (Paternò-Büchi type reaction) to give unprecedented 1-alkyl-6-oxa-2-silabicyclo[2.2.0] hexanes.
Surface mediated phenomena are important in controlling the magnetism of nanocrystals. Here, we provide a versatile chemical method which allows the formation of EuS nanocrystals encapsulated in poly(styrene) (PS). These materials are the first example of a polymer based EuS nanocomposite prepared in situ. Besides the…
A computational fluid dynamics model is developed to study the steady-state behavior of a microtubular solid oxide fuel cell ͑SOFC͒.The model incorporates mass, momentum, species, and heat balances along with ionic and electronic charge transfers.The anode-supported SOFC studied in this work consists of a ceria-based…
Thermoplastic vulcanizate (TPV) is a special class of thermoplastic elastomers (TPEs) made of a rubber/plastic polymer mixture in which the rubber phase is highly vulcanized. It is prepared by melt mixing a thermoplastic with an elastomer and by in situ crosslinking of the rubber phase. Currently, TPV is replacing EPD…
A small molecule of N,N′,N″-tris(3-methylpyridyl)-trimesic amide was assembled into a novel hexagonal microtube through intermolecular hydrogen bonds, and simultaneously formed a gel system in H2O–THF mixed solvent. Tuning gelator concentration or the preparation method can effectively control the size of the hexagona…
An ingrowing toenail has no definitive treatment. Previously, effective methods were complicated but easy ones had less effect. We show both an easy and an effective way with Cu-Al-Mn-based shape-memory alloys (SMAs). They have a characteristic shape which patients themselves can detach easily without any pain. But th…
The states of tris(8-quinolinato)aluminum(III) (Alq3) adsorbed in mesoporous silicas with different pore sizes (2.5, 3.1 and 5.0 nm) were investigated. Alq3 was successfully occluded into the mesoporous silicas from solution and the adsorbed amount of Alq3 per BET surface area was effectively controlled by changing th…
