Alkali halide clusters are interesting model systems that can provide information about how crystal properties evolve. To study these properties, a high-resolution atmospheric pressure inlet time-of-flight mass spectrometry （APi-TOF-MS） study of the sequential sodium halides series, C1-（NaC1）n and Br-（NaBr）m, has been reported, and the viability of the APi-TOF- MS equipped with an electrospray ionization source in determining cluster compositions has been demonstrated. The isotopic patterns were well resolved, as n=4 and 7 were determined to be the magic numbers for C1-（NaC1）n clusters, which were particularly abundant in the mass spectra. A global minimum search based on density functional theory enabled basin hopping yield the most stable structures for the mentioned series. The structures exhibit several distinct motifs which can be roughly categorized as linear chain, rock salt, and hexag- onal ring. This work provides an effective way to discover and elucidate the nonstoichiometry sodium halide clusters. These clusters possess very high vertical detachment energies and are generally called as superhalogens, which play important roles in chemistry because they are widely used in the synthesis of new classes of charge-transfer salts.

The ozonolysis of cyclohexene is an important model system for understanding the more complex reaction of O_3 with monoterpenes; however, many previous studies have come to qualitatively different conclusions about the composition of the secondary organic aerosol(SOA)formed in this system. In the present study, the composition of the SOA produced by cyclohexene ozonolysis in the absence of seed aerosols has been investigated online and off-line using synchrotron-based thermal desorption/tunable vacuum ultraviolet photoionization time-of-flight aerosol mass spectrometry(TD-VUV-TOF-PIAMS) in conjunction with a custom-built smog chamber. On the basis of the molecular ions observed by mass spectrometry at 11.5 e V, it was found that dicarboxylic acids, dialdehydes, and cyclic anhydrides are the predominant low molecular weight components in the particle phase. The results also indicated that TD-VUV-TOF-PIAMS coupled with filter sampling is a potentially useful tool for the investigation of SOA composition both in the field and in the laboratory.

传统的国家主权观念认为，国家主权是不受限制的，是不能谈判更不能转让的。然而，欧洲一体化的实践却突破了这种传统的观念，出现了主权转让的现象，而且转让的不仅仅是一般的主权，还包括关税主权、货币主权在内的经济主权和政治主权，国家主权的这种大范围、深层次的转让，是欧洲一体化的一大特色。欧洲一体化内主权的转让具有自主自愿性、互让共享性、循序渐进性和民主制衡性等特点，正是这些特点才决定了主权转让的可行性和可持续运行。欧洲一体化的实践为我们在经济全球化、区域一体化的国际背景下，如何更好地坚持主权原则提供了新的思路。

High-resolution non-emissive displays based on electrochromic tungsten oxides (WOx) are crucial for future near-eye virtual/augmented reality interactions, given their impressive attributes such as high environmental stability, ideal outdoor readability, and low energy consumption. However, the limited intrinsic structure of inorganic materials has presented a significant challenge in achieving precise patterning/pixelation at the micron scale. Here, we successfully developed the direct photolithography for WOx nanoparticles based on in situ photo-induced ligand exchange. This strategy enabled us to achieve ultra-high resolution efficiently (line width m, the best resolution for reported inorganic electrochromic materials). Additionally, the resulting device exhibited impressive electrochromic performance, such as fast response ( 3600 cycles), as well as promising applications in electronic logos, pixelated displays, flexible electronics, etc. The success and advancements presented here are expected to inspire and accelerate research and development (R&D) in high-resolution non-emissive displays and other ultra-fine micro-electronics.

The oxidation of 3-picoline to nicotinic acid took place efficiently in an ethanol solution with 02 as the oxidant under the catalysis of T（o-Cl）PPMn at 40--150 ℃ and 0.5--3.0 MPa oxygen pressure. The influences of temperature, oxygen pressure, reaction time, concentration of 3-picoline, concentration of sodium hydroxide, and concentration of T（o-Cl）PPMn catalyst, etc. on the production of nicotinic acid were investigated. The results show that T（o-Cl）PPMn presented excellent catalytic activity in the oxidation Of 3-pieoiine to nicotinic acid and the yield of nicotinic acid varied greatly with the reaction temperature, oxygen pressure, T（o-Cl）PPMn concentration, etc.
