The preparation of 2D-layered C@TiN: Ti3C2 MXenes were synthesized via the previous reported paper. Typically, 1 g Ti3AlC2 (purchased from FORSMAN Company, China) was added into 15 mL 40% HF solution. The solution was stirred for 120 h at 40 oC. After the HF etching, the material was centrifuged and washed in deionized water until pH~7. The Ti3C2 MXene was obtained after drying at 50 oC for 12h...
The microstructure and magnetic properties of the FePt films grown on large mismatched ZrN (15.7%) intermediate layer were investigated. With using ZrN intermediate layer, FePt 10 nm films exhibited (001) texture except for some weaker FePt (110) texture. Good epitaxial relationships of FePt (001) <100>//ZrN (001) <100>//TiN (001) <100> among FePt and ZrN/TiN were revealed from the transmission...
Work reported in recent years from this laboratory has outlined the general features of poisoning in animals given diand trialkyl tin salts (Stoner, Barnes, and Duff, 1955). More detailed accounts of the cerebral oedema produced by triethyl tin in rats (Magee, Stoner, and Barnes, 1957) and the bile duct and liver lesions produced by dibutyl tin salts in rats and mice have also been prepared (Ma...
A novel noble metal-free catalyst, with nitrogen-doped amorphous carbon and titanium nitride particles supported on SiC (NC-TiN/SiC), was synthesized. The NC-TiN/SiC catalyst exhibited excellent oxygen reduction reaction activities as well as superior stability and methanol tolerance. The catalytic activities were attributed to the synergistic effect of TiN and NC.
A tin-catalyzed reaction of α-hydroxy ketones with 1,1-dicyanoalkenes produced 2-amino-4,5-dihydrofuran-3-nitriles. In the catalytic reaction, tin enolates were generated from α-hydroxy ketones as active catalytic species. The highly basic ability of the Sn-O bonds played an important role in the reactions. This tin-catalyzed reaction was highly atom-economical and required no other metal reage...
the equilibrium constant of adduct formation between some triorganotin chloride of the type r3sncl (r=c6h5, p-ch3c6h4, n-ch3)ch2)3, c6h5-ch2 and lewis bases cl¯, br¯, and i¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. the average equilibrium constant values for the systems studied shows the following acceptor trend of tin(iv) in the triorganotin chlorides: p-tolyl > ...
nano tin dioxide was employed as a catalyst for efficient and facile preparation of pyran derivatives via the one-pot three component condensation reaction of various aldehydes with malononitrile and dimedone. chromene derivatives via the one-pot three component condensation reaction of various aldehyde with malononitrile and 4-hydroxycoumarin were also synthesized by this novel catalyst. the d...
Although patients with anorexia nervosa (anorexia) are known to show tubulointerstitial nephritis (TIN), the pathophysiology of its progression is not fully understood. We herein report a 31-year-old woman with anorexia who showed acute exacerbation of chronic kidney disease. Renal biopsy showed non-uniform chronic TIN; some areas were obsolete lesions and other areas were active lesions. In ad...
As the electronics industry begins to focus upon the tin-silver-copper family of alloys as a viable replacement for tin-lead solders, research needs to be done to determine if any particular alloy is best suited for the broadest range of applications. The tin-silver-copper family of alloys has earned a great deal of positive response from various industry consortia and organizations in recent y...
Cellular and fluid exudation in the interstitial tissue was noted by Councilman in 1898, while he studied kidneys of patients who died of scarlet fever and diphtheria (1). Councilman also determined that these kidneys did not contain bacteria (they were sterile). He called the condition acute interstitial nephritis (AIN). The term interstitial nephritis connotes predominant involvement of the r...
