The properties of hydrolyzed feather keratin (HFK) were compared to those of hydrolyzed wool keratin (HWK) with the aim of developing better ways to utilize feather keratin waste. Amino acid analysis showed that HFK contained more hydrophobic amino acids did than HWK. Although gel permeation chromatography indicated t…
Approximate efficiency of a linear regulator, if the power consumed by the control circuits is negligible, can be expressed by the ratio of Vo/Vin. A very low frequency supercapacitor circulation technique can be combined with commercial low-dropout (LDO) regulator integrated circuits to achieve significantly high end…
In this letter, microwave annealing technology is proposed to reduce thermal budget for the manufacture of transparent conductive oxide thin-film transistor (TFT). With microwave annealing, a nitrogenated amorphous In-Ga-Zn-O (a-IGZO:N) TFT fabricated on glass panel behaves as a carrier mobility of 4.21${\rm cm}^{2}/{…
Kristalle in Bewegung: Bei Bestrahlung mit Licht springen und hüpfen Kristalle der Cobalt-Koordinationsverbindung [Co(NH3)5(NO2)]Cl(NO3) und legen dabei Distanzen zurück, die 102- bis 105-Mal größer als sie selbst sind, um die Spannung abzubauen, die sich in ihrem Inneren aufbaut. Die erste quantitative kinematische A…
EuNi2P2 is known as a heavy fermion compound with an electronic specific heat coefficient γ=100 mJ/(K2 \(\cdot\)mol). We grew single crystals and studied their electronic and magnetic properties by measuring the electrical resistivity, magnetic susceptibility, high-field magnetization, specific heat, and thermal expan…
Experimental demonstration of silicon inverse opal photonic crystals (PhCs) as a wave-optics-based back reflector for polycrystalline silicon solar cells is shown. Using a novel S5 process, crack-free three dimensional PhCs are fabricated, which are free-standing and have good optical properties. An efficiency enhance…
A repetitive control system (RCS) provides good control performance for periodic signals, but it may not satisfactorily reject aperiodic disturbances. Our solution is an equivalent-input-disturbance (EID)-based RCS in which aperiodic disturbances are estimated by an EID estimator and rejected by incorporation of the e…
Spatial light modulation can be used to address specific fiber modes, as required in mode-division multiplexed systems. We theoretically compare phase-only spatial light modulation to a combination of amplitude and phase spatial light modulation in terms of insertion loss and crosstalk for a fiber supporting 11 LP mod…
Liquids with no ions! Raman analysis and quantum calculations suggest that electrically neutral molecular species predominantly exist in an N-methylimidazole and acetic acid equimolar mixture, and that ionic species are rather minor. Nevertheless, the mixture has significant ionic conductivity, and shows "good ionic"…
Bigger is better: Sequential backbone assignments are obtained by NMR spectroscopy for a 1 MDa proteasome complex. The method relies on immobilization of a soluble protein complex by magic-angle spinning. Deuteration and proton detection of exchangeable sites and paramagnetic relaxation enhancement enables exploration…
OBJECTIVES: A vast number of blinding diseases have genetic aetiologies and may be treated by molecular based therapies such as antisense oligonucleotides or short interfering RNA. However, treatment success of ocular gene therapy is highly dependent on efficient delivery of such molecules. KEY FINDINGS: The majority…
The recent literature has shown an increase in the number of co-crystals reported to be polymorphic, with at least 45 such systems identified thus far. The question of whether co-crystals, defined as any multicomponent neutral molecular complex that forms a crystalline solid, are inherently less prone to polymorphism…
The fluorescent probes having complete spectral separation between absorption and emission spectra (large Stokes shift) are highly useful for solar concentrators and bioimaging. In bioimaging application, NIR fluorescent dyes have a greater advantage in tissue penetration depth compared to visible-emitting organic dye…
Fullerene bisadducts have emerged as promising electron‐accepting materials because of their ability to increase the open‐circuit voltage (VOC) of polymer solar cells (PSCs) due to their relatively high lowest unoccupied molecular orbital (LUMO) energy levels. It should be noted that the as‐prepared fullerene bisadduc…
Developing highly active hydrodesulfurization (HDS) catalysts is of great importance for producing ultraclean fuel. Herein we report on crystalline mordenite nanofibers (NB-MOR) with a bundle structure containing parallel mesopore channels. After the introduction of cobalt and molybdenum (CoMo) species into the mesopo…
Catalytic cracking of Canadian oil sand bitumen in supercritical water was performed to clarify the effect of CeO 2 nanoparticles. The cracking was performed at 723 K to promote a redox reaction between the water, bitumen, and catalyst for the production of hydrogen and oxygen. As the catalyst, CeO 2 with two differen…
Stable pH is an established biomarker of health, relevant to all tissues of the body, including the heart. Clinical monitoring of pH in a practical manner, with high spatiotemporal resolution, is particularly difficult in organs such as the heart due to its soft mechanics, curvilinear geometry, heterogeneous surfaces,…
Bismuth tri-iodide (BiI3) is an intermediate band gap semiconductor with potential for room temperature gamma-ray detection applications. Remarkably, very different band gap characteristics and values of BiI3 have been reported in literature, which may be attributed to its complicated layered structure with strongly b…
InVO4 has attracted much attention as an anode material due to its high theoretical capacity. However, the effect of preparation methods and conditions on morphology and energy storage characteristic has not been extensively investigated and will be explored in this project. InVO4 anode material was prepared using fiv…
The new homoleptic ate U(III) siloxide [K(18c6)][U(OSi(O(t)Bu)3)4] 2 was prepared in 69% yield by reduction of [U(OSi(O(t)Bu)3)4] 3 with KC8. The reaction of the neutral U(III) siloxide complex [U(OSi(O(t)Bu)3)2(μ-OSi(O(t)Bu)3)]2 1 with adamantyl azide leads to the isolation of the dinuclear U(VI) imido complex [U2(NA…
