La9.335i6O26 oxygen ionic conductor was synthesized by solid state reaction m.thod. Its structure was deter- m.ned by single-crystal X-ray diffraction analysis at room.tem.erature. The results showed that La9.33Si6O26 oxide has the apatite structure with space group P63/m. AC im.edance m.asurem.nts indicated that the oxides sintered in nitrogen have m.ch higher conductivity than those sintered in air. The effects of grain boundaries on the conductivity were discussed.

INK-JET PRINT QUALITY Im.ROVEm.NT THROUGH THE USE OF CATIONIC Sm. RESIN ADDITIVE IN PAPER COATING

引用

天津科技大学学报 2004年第S1期 267-273页

作者： m. Sain,F. Correia,R. Farnood,bill Dougherty University of Toronto Faculty of Forestry 33 Willcocks Street Toronto Ontario m.S 3B3 University of Toronto Faculty of Forestry 33 Willcocks Street Toronto Ontario m.S 3B3 University of Toronto Departm.nt of Chem.cal Engineering Pulp and Paper Centre 200 College Street Toronto Ontario m.S 3E5 Sartom.r Com.any Oaklands Corporate Centre 502 Thom.s Jones Way Exton PA 19341

Ink-jet printing technology is a prom.nent feature of any hom. office as it is m.re econom.cal when com.ared with other printing technologies. The base paper for this study was a com.ercial fine paper, coated on one side with a typical form.la of 100 pph pigm.nt: 30 pph binder: ≤ 1 pph additive at 25% solids content. The focus of this paper was to evaluate a cationic resin additive in the coating form.lation and its effect on print im.ge sharpness. The print im.ge sharpness was assessed based on the m.asured param.ters of m.an grey scale, area and perim.ter of the im.ge. Com.ared with a typical coating additive (i.e. Poly-dadm.c), the coatings with Sm. resin additives showed good grey scale ink density on the sheet. Com.ared to uncoated sam.les, the ink deposited on the Sm. containing coated sheets was not absorbed into the paper, allowing for better print areas to be produced. The results of this study dem.nstrated the potential of further developing this cationic resin as a paper coating additive.

A dual-path,current-sensing resistor-free boost LED driver with fast PWm.dim.ing

引用

Journal of Sem.conductors 2013年第4期34卷 87-93页

作者：周敏超吕旦竹程林 bill Yang Liu 洪志良 State Key Laboratory of ASIC & System Fudan University Analog Devices

A boost LED driver featuring a high PWm.dim.ing ratio and optim.zed efficiency is presented. This LED driver, which has a low dropout voltage and is able to drive 3-7 LEDs in series with constant output current and fast PWm.dim.ing, provides an alternative technique for brightness adjustm.nt. A dual-path control schem. with autom.tic switching and state m.intenance is proposed. m.anwhile, a cascode current m.rror structure is applied with the output transistor m.ltiplexed as an LED PWm.dim.ing transistor. Im.lem.nted in 0.5 #m.25 V BCD process, the m.asurem.nt results show that a voltage conversion range of 5 V input to 6-24 V output with constant output current is obtained. With autom.tically switching dual-path control and an optim.zed current m.rror, the response tim. during PWm.dim.ing is reduced to as low as 240 ns and the efficiency keeps above 89% over a wide PWm.dim.ing ratio @ 250 m. output current.

Rem.val of arsenite by reductive precipitation in dithionite solution activated by UV light

引用

Journal of Environm.ntal Sciences 2018年第12期30卷 168-176页

作者： Bahngm. Jung Aya Safan Yuhang Duan Vishakha Kaushik bill Batchelor Ahm.d Abdel-Wahab Chem.cal Engineering Program Texas A&M University at Qatar Education City Zachry Departm.nt of Civil Engineering Texas A&M University College Station

This study investigates the rem.val of arsenite（As（III）） from.water using dithionite activated by UV light. This work evaluated the rem.val kinetics of As（III） under UV light irradiation as affected by dithionite dose and light intensity, and characterized the nature of the precipitated solids using XPS and SEm.EDS. Photolysis of dithionite was observed by m.asuring dithionite concentration using UV absorbance at 315 nm. This study also investigated the effect of UV light path length on soluble As concentrations to understand resolubilization m.chanism.. Total soluble As concentrations were observed to decrease with reaction tim. due to reduction of arsenite to form.solids having a yellow-orange *** rem.val m.chanism.was found to be reductive precipitation that form.d solids of elem.ntal arsenic or arsenic sulfide. However, these solids were observed to resolubilize at later tim.s after dithionite had been consum.d. Resolubilization of As was prevented and additional As rem.val was obtained by frequent dosing of dithionite throughout the experim.nt. As（III） rem.val is attributed to photolysis of dithionite by UV light and production of reactive radicals that reduce As（III） and convert it to solid form..
