A BSTRACT Hydrothermal treatment of nanoscale amorphous ceric phosphate gel in KOH aqueous solutions was found to result in a new KCe 2 (PO 4 ) 3 phase. The refinement of the KCe 2 (PO 4 ) 3 structure showed that it was isostructural to recently reported (NH 4 )Ce 2 (PO 4 ) 3 . For the KCe 2 (PO 4 ) 3 phase, the unit cell parameters (sp. gr. C 2 /c ) were a = 17 . 3781(3) ˚A, b = 6 . 7287(1) ˚A, c = 7 . 9711(2) ˚A, β = 102 . 351(1) ◦ , V = 910 . 53(4) ˚A 3 , Z = 4 . The thermal decomposition of KCe 2 (PO 4 ) 3 at 800 ◦ C resulted in the mixture of crystalline CePO 4 and KPO 3 .
在KOH水溶液中对纳米级无定形磷酸铈凝胶进行水热处理，得到了一种新的kce2 (po4) 3相。对kce2 (po4) 3结构的改进表明，它与最近报道的(nh4) ce2 (po4) 3具有相同的结构。对于kce2 (po4) 3相，单元胞参数(sp. gr. c2 / C)为a = 17。3781(3)˚A, b = 6。7287(1)˚A, c = 7。9711(2)˚a， β = 102。(1)◦，v = 910。53(4)˚a 3, z = 4。kce2 (po4) 3在800℃下热分解，形成结晶型的cepo4和kpo3的混合物。

A BSTRACT The influence of the coprecipitation of bismuth and iron hydroxides in microreactors of various types on the formation of nanocrystalline bismuth orthoferrite during the heat treatment of the deposit was described. Free impinging-jets microreactor, microreactor with submerged jets, microreactor with intensively swirling flows were used. It was revealed that nanocrystalline bismuth orthoferrite with the smallest weighted average crystallite size of 12 nm is formed when a microreactor with tangentially swirling flows of reagent solutions is used for coprecipitation of hydroxides. The minimum size of BiFeO 3 crystallites according to transmission electron microscopy data is determined as 3–4 nm.

A BSTRACT Carbon nanoparticles materials in polymer modification have gained particular importance in modern potentiometric studies after they were discovered to be ion-to-electron transducers in solid-contact ion-selective electrodes (SC-ISEs). This paper describes the preparation and comparative evaluation of poly(vinyl chloride) (PVC) and Nafion membranes incorporated with light fullerene C60, single carbon nanotubes (SWC-NTs) and their mixture as transducer interlayers in the SC-ISE based on the ion-sensing PVC-membrane containing a high lipophilic 2-[bis-octadecyl sulfonic)- closo -decaborate anion. The best electroanalytical performance was achieved for the sensor fabricated with the transducer made by combining two transducing layers, a Nafion film modified with fullerene C60 and a plasticized PVC film modified with SWCNTs-C60 hybrid filler, which were sequentially applied onto the substrate carbositall electrode surface. The test results showed that the newly prepared a layer-by-layer SC-ISE is suitable for the sensitive determination of local anesthetics and some other protonable nitrogen-containing drugs.
