Epitaxial copper ferrite thin films were deposited on MgO substrates by the alternating target laser ablation deposition method. A series of films was studied to explore the impact of oxygen operating pressure, substrate temperature, and the ratio of laser shots incident on each target upon the magnetic, structural, and atomic structural properties. The highest saturation magnetization, 2800 G,...

A 5-pole lumped element bandpass filter (BPF) of center frequency 264.05 MHz and fractional bandwidth (FBW) 0.76% is designed and fabricated using YBa 2 Cu 3 O 7-d (YBCO) thin films deposited on both sides of a MgO substrate(40 mm × 40 mm × 0.5 mm). The return loss, minimum insertion loss and ripple were measured to be 20.0 dB, less than 0.1 dB and less than 0.1 dB at 70 K, respectively. These ...

In a previous publication, ball milling was introduced as an effective method for the preparation of supported metal catalysts, simply from coarse powders and oxide support. this follow-up study, we demonstrate that mixing multiple sources can result in alloyed nanoparticles, extending field application to synthesis bimetallic catalysts. Ball Au Pd or Cu high-energy regime (shaker mill) indeed ...

An important part of pathogenesis of Alzheimer's disease (AD) is attributed to the contribution of AGE (Advanced Glycation Endproducts) and ALE (Advanced Lipid peroxidation Endproducts). In order to attenuate the progression of AD, we designed a new type of molecules that consist of two trapping parts for reactive carbonyl species (RCS) and reactive oxygen species (ROS), precursors of AGE and A...

We study the spin orbit torque (SOT) and Dzyaloshinskii-Moriya interaction (DMI) in the dual-interfaced Co-Ni perpendicular multilayers. Through the combination of top and bottom layer materials (Pt, Ta, MgO and Cu), SOT and DMI are efficiently manipulated due to an enhancement or cancellation of the top and bottom contributions. However, SOT is found to originate mostly from the bulk of a heav...

In situ studies have been performed on thin films in the Al rich region of the Al–Cu–Fe–Cr quasicrystalline phase field. Thin films were grown by magnetron sputtering on atomically flat MgO (0 0 1) and Al O (0 0 0 1) and subsequently studied by 2 3 transmission electron microscopy and X-ray photoelectron spectroscopy. High resolution electron microscopy shows that thin films (-30 nm) grown at r...

The detectivity D* limits of YBa(2)Cu(3)O(7-x) bolometers on 0.05-cm-thick crystalline substrates are investigated, and a method to increase D* to greater than 10(9) (cm Hz(1/2))/W at a 20-microm wavelength is proposed. Because the response increases proportionally with the bias current I(b), whereas the noise near T(c) (the transition or critical temperature) of our MgO and SrTiO(3) substrate ...

Grain growth in 40-nm-thick Cu films encapsulated by overand under-layers of SiO2, Al2O3, Si3N4, and MgO was investigated. The films were magnetron sputter deposited onto cooled SiO2/Si substrates in an ultrahigh vacuum purity environment. Ex situ annealing was performed at 400 and 800 °C in 1 atm reducing gas. Films deposited at −120 °C exhibited more extensive grain growth after annealing tha...

A novel MgO-patched TiO2 microsphere photocatalyst demonstrated 10 times higher activity toward CO production from CO2 photoreduction with H2O vapor, when the reaction temperature increased from 50 to 150 °C. The catalytic performance of hybrid MgO-TiO2 was much more stable than TiO2, particularly at a higher temperature, likely due to easier desorption of reaction intermediates and the enhance...

The influence of several nootropic drugs (piracetam, pyritinol, meclofenoxat, methylglucamine orotate (MGO) and dihydroergotoxine (DHET) on both the ethanol preference and the enhanced seizure susceptibility after a single dose of ethanol was studied. Piracetam, MGO and DHET reduce the ethanol drinking in ethanol-preferring mice. The enhanced seizure susceptibility after a single dose of ethano...
