Ion transport in semicrystalline solid polymer electrolytes
Solid polymer electrolytes (SPEs) with both high room temperature ionic conductivity and mechanical integrity are highly desirable for all-solid-state lithium batteries. Linear polyethylene oxide (PEO) represents the simplest yet most attractive solvating polymer due to its capability to form complex with a selected n…
Peptide targeting of fluorescein-based sensors to discrete intracellular locales
Fluorescein-based sensors are the most widely applied class of zinc probes but display adventitious localization in live cells. We present here a peptide-based localization strategy that affords precision in targeting of fluorescein-based zinc sensors. By appending the zinc-selective, reaction-based probe Zinpyr-1 dia…

Hysteresis Losses Evaluation in Electromagnetic Devices under Non Sinusoidal Induction Waveforms
This paper deals with the evaluation of hysteresis losses in electromagnetic devices under non sinusoidal induction waveforms. The originality of this work lies on the fact that it is not necessary to perform Fourier Transform of the applied waveforms, as it is usually presented in the literature to calculate the hyst…

Для синтеза карбидов вольфрама был\nиспользован СВС карбида титана в смеси «вольфрам-титан-сажа», который далее\nини…
Determine Mechanism of CH3I Capture in AgZ.
The selective capture of radiological iodine ( 129 I) is a persistent concern for safe nuclear energy.In nuclear fuel reprocessing scenarios, the gas streams to be treated are extremely complex, containing several distinct iodine-containing molecules amongst a large variety of other species.Silver-containing mordenite…
PCBs의 스크랩으로부터 Au 용출과 회수
폐 PCBs의 스크랩으로부터 염소-차아염소산염 용액을 이용하여 Au와 Ag를 친환경적이고 효과적으로 용출시키고자 하였다. PCBs에 Cu, Sn, Sb, Al, Ni, Pb, Au 등과 같은 유용금속이 함유되어 있는 것을 EDS 분석으로 확인하였다. 최대 Au 용출율은 1%의 광액농도, 2:1의 염산:차아염소산나트륨 그리고 2 M의 NaCl 농도조건이다. Au 회수율이 가장 높은 메타중아황산나트륨 농도는 3 M에서였다. 염소-차아염소산염이 폐 컴퓨터에 함유되어 있는 Au와 Ag를 효과적으로 용출시킬 수 있는 용매제 임을 그리고 메타중아황산나트륨이 Au를 간단하게 침…
Lattice deformation in thin BiFeO3 and Ba0.8Sr0.2TiO3 epitaxial films on (001)MgO single crystalline substrates
Bi 0.98 Nd 0.02 FeO 3 (BNFO) and Ba 0.8 Sr 0.2 TiO 3 (BST) epitaxial films produced by rf cathode sputtering on (001)MgO substrates are studied by means of XRD. The thickness dependences of uniform lattice deformations and linear dislocation density, generated due to epitaxial stress relaxation, are plotted.
Centrifugal contactor operations for UREX process flowsheet. An update
The uranium extraction (UREX) process separates uranium, technetium, and a fraction of the iodine from the other components of the irradiated fuel in nitric acid solution. In May 2012, the time, material, and footprint requirements for treatment of 260 L batches of a solution containing 130 g-U/L were evaluated for tw…
