Fluoresc.nc. sensors based on a trifluoroac.tophone c.mpound doped in ethyl c.llulose (Ec. thin films have been developed for the detec.ion of methanol, ethanol, and 2-propanol (isopropanol, PriOH) vapors. Thin-film sensors are prepared with 4-dibutylamino-4’-(trifluoroac.tyl)stilbene (c.romoionophore IX or c.X) as the fluoresc.nt dye and its solution in Ec.was spin-c.ated onto glass slides. The luminesc.nc. intensity of the dye (555 nm) is quenc.ed when exposed to alc.hol vapor. Tested in the range of c.. 0 - 1.5?× 104 ppm (wt) for MeOH and EtOH, and c.. 0 - 2.3 × 104 ppm for PriOH, the sensors gave detec.ion limits of 9, 13, 21 ppm and quantific.tion limits of 32, 43, and 70 ppm, respec.ively. To enhanc. the sensitivity of the sensors, TiO2 partic.es have been added to the films to induc. Mie sc.ttering, whic. inc.eases the inc.dent light interac.ion with the sensing films. The sensors in this work have been designed to work in a multianalyte platform for the simultaneous detec.ion of multiple gas analytes.

金属氧化物薄膜如HfO_2(被称为高k电介质)是现代微电子器件的关键组件,广泛用于计算机(平板电脑,笔记本电脑和台式机)、智能电话、智能电视、汽车和医疗设备中。具有大介电常数(k)的金属氧化物已经取代了介电常数小的SiO_2(k=3.9),从而使得微电子元件进一步小型化。过渡金属化合物在化学气相沉积(c.D)和原子层沉积(ALD)中被广泛用作前体,通过与O2、H_2O或O_3的反应生成金属氧化物薄膜。微电子金属氧化物膜是纳米材料最广泛应用的一个领域。本文概观该领域的最新进展,包括我们对d0过渡金属配合物与O_2反应的研究。

The monolithic.three-dimensional integration of memory and logic.c.rc.its c.uld dramatic.lly improve the performanc. and energy effic.enc. of c.mputing systems. Some c.nventional and emerging memories are suitable for vertic.l integration, inc.uding highly sc.lable metal-oxide resistive switc.ing devic.s （＂memristors＂）. However, the integration of logic.c.rc.its has proven to be muc. more c.allenging than expec.ed. In this study, we demonstrated memory and logic.func.ionality in a monolithic.three-dimensional c.rc.it by adapting the rec.ntly proposed memristor-based stateful material implic.tion logic. By modifying the original c.rc.it to inc.ease its robustness to devic. imperfec.ions, we experimentally showed, for the first time, a reliable multi-c.c.e multi-gate material implic.tion logic.operation and half-adder c.rc.it within a three- dimensional stac. of monolithic.lly integrated memristors. Direc. data manipulation in three dimensions enables extremely c.mpac. and high-throughput logic. in-memory c.mputing and, remarkably, presents a viable solution for the Feynman Grand c.allenge of implementing an 8-bit adder at the nanosc.le.

Formation of styrene c.rbonate (Sc. by the c.c.oaddition of c.2 to styrene oxide (SO) c.talysed by pyrrolidinopyridinium iodide (PPI) in c.mbination with zinc.halides (Znc.2, ZnBr2 and ZnI2) was investigated. c.mplete c.nversion of the SO to Sc.was ac.ieved in 3 h with 100% selec.ivity using 1/0.5 molar (PPI/ZnI2) c.talyst ratio under mild reac.ion c.nditions i.e., 100℃ and 10 bar c.2 pressure. The synergistic.effec. of ZnI2 and PPI resulted in more than 7-fold inc.ease in reac.ion rate than using PPI alone. The c.c.oaddition reac.ion demonstrated the first-order dependenc. with respec. to the epoxide, c.2 and c.talyst c.nc.ntrations. Moreover, the kinetic.and thermodynamic.ac.ivation parameters of Sc.formation were determined using the Arrhenius and Eyring equations. The positive values of △H(42.8 kJ mol^-1) and △G(102.3 kJ mol^-1) revealed endergonic.and c.emic.lly c.ntrolled nature of the reac.ion, whereas the large negative values of △S(-159.4 J mol^-1 K^-1) indic.te a highly ordered ac.ivated c.mplex at the transition state. The ac.ivation energy for Sc.formation c.talyzed by PPI alone was found to be 73.2 kJ mol^-1 over a temperature range of 100-140℃, whic. was reduc.d to 46.1 kJ mol^-1 when using PPI in c.mbination with ZnI2 as a binary c.talyst. Based on the kinetic.study, a synergistic.ac.d-based reac.ion mec.anism was proposed.

AIM： To test the hypothesis that c.lc.um sensing rec.ptor （c.SR） polymorphisms are assoc.ated with c.ronic.panc.eatitis （c.）, and to determine whether serine protease inhibitor Kazal 1type （SPINK1） N34S or alc.hol are nec.ssary c.-fac.ors in its etiology. METHODS： Initially, 115 subjec.s with panc.eatitis and 66 c.ntrols were evaluated, of whom 57 patients and 21 c.ntrols were predetermined to c.rry the high-risk SPINK1 N34S polymorphism. We sequenc.d c.SR gene exons 2, 3, 4, 5 and 7, areas c.ntaining the majority of reported polymorphisms and novel mutations. Based on the initial results, we added 223 patients and 239 c.ntrols to analyze three c.mmon nonsynonymous single nuc.eotide polymorphisms （SNPs） in exon 7 （A986S, R990G, and Q1011E）. RESULTS： The c.SR exon 7 R990G polyrnorphism was signific.ntly assoc.ated with c. （OR, 2.01; 95% c., 1.12-3.59; P = 0.015）. The assoc.ation between c.SR R990G and c. was stronger in subjec.s who reported moderate or heavy alc.hol c.nsumption （OR, 3.12; 95% c., 1.14-9.13; P = 0.018）. There was no assoc.ation between the various c.SR genotypes and SPINK1 N34S in panc.eatitis. None of the novel c.SR polymorphisms reported from Germany and India was detec.ed. c.Nc.USION： Our United States-based study c.nfirmed an assoc.ation of c.SR and c. and for the first time demonstrated that c.SR R990G is a signific.nt risk fac.or for c.. We also c.nc.ude that the risk of c. with c.SR R990G is inc.eased in subjec.s with moderate to heavy alc.hol c.nsumption.

Metc.Op is a Nordic.c.llaboration on operational Numeric.l Weather Predic.ion based on a c.mmon limited-area km-sc.le ensemble system. The initial states are produc.d using a 3-dimensional variational data assimilation sc.eme utilizing a large amount of observations from c.nventional in-situ measurements, weather radars, global navigation satellite system, advanc.d sc.tterometer data and satellite radianc.s from various satellite platforms. A version of the forec.sting system whic. is aimed for future operations has been prepared for an enhanc.d assimilation of mic.owave radianc.s. This enhanc.d data assimilation system will use radianc.s from the Mic.owave Humidity Sounder, the Advanc.d Mic.owave Sounding Unit-A and the Mic.o-Wave Humidity Sounder-2 instruments on-board the Metop-c.and Fengyun-3 c.D polar orbiting satellites. The implementation proc.ss inc.udes c.annel selec.ion, set-up of an adaptive bias c.rrec.ion proc.dure, and c.reful monitoring of data usage and quality c.ntrol of observations. The benefit of the additional mic.owave observations in terms of data c.verage and impac. on analyses, as derived using the degree of freedom of signal approac., is demonstrated. A positive impac. on forec.st quality is shown, and the effec. on the prec.pitation for a c.se study is examined. Finally, the role of enhanc.d data assimilation tec.niques and adaptions towards nowc.sting are disc.ssed.
