[en] Graphical abstract: Chalcopyrite structured CuInS₂ nanorods were synthesized by an environmentally friendly microwave heating method in deep eutectic solvent. Results show that microwave heating time plays an important role in the formation of CuInS₂ nanostructure phase. The SEM results indicated that the obtained CuInS₂ nanostructures display rod-like morphology with diameters of about 40 nm and lengths of about 400 nm. The UV–vis spectrum results indicated that the CuInS₂ nanorods exhibit strong absorption from the entire visible light region to the near-infrared region beyond 1100 nm. The possible growth mechanism of CuInS₂ nanorods was discussed. - Abstract: Chalcopyrite structured CuInS₂ nanorods were synthesized by an environmentally friendly microwave heating method in deep eutectic solvent. The as-synthesized CuInS₂ nanorods were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), respectively. The results indicated that the obtained CuInS₂ nanostructures display rod-like morphology with diameters of about 40 nm and lengths of about 400 nm. The influences of microwave heating time on the formation of CuInS₂ phase were discussed. Ultraviolet–visible (UV–vis) and photoluminescence (PL) spectra were utilized to investigate the optical properties of CuInS₂ nanorods. The results showed that the as-synthesized CuInS₂ nanorods exhibit strong absorption from the entire visible light region to the near-infrared region beyond 1100 nm. PL spectrum of the as-synthesized CuInS₂ nanorods displays an emission peak centered at 580 nm under excitation wavelength of 366 nm at room temperature. The possible growth mechanism of CuInS₂ nanorods was discussed

[en] We consider the Schrödinger-Poisson system: −ε²Δu + V(x)u + ϕ(x)u = f(u),−Δϕ = u² in R³, where the nonlinear term f is of critical growth. In this paper, we construct a solution (u_ε, ϕ_ε) of the above elliptic system, which concentrates at an isolated component of positive locally minimum points of V as ε → 0 under certain conditions on f. In particular, the monotonicity of (f(s))/(s³) and the so-called Ambrosetti-Rabinowitz condition are not required

[en] Application of DCS in Ling Ao Ⅱ is a major technical improvement, which adopt German Siemens' TELEPERM XP and AREVA's TELEPERM XP. The cabinet is mainly installed at the level of +11.5 m and +15.5 m of the electric's building LX and connection building WX. The main control room is located at LX+19.4 m, the civil structure is the same as Ling Ao Ⅰ. A lot of problems was raised by design, supply and civil construction during the installation of DCS cabinet, which can not meet the requirement. For various reasons, some problems also existed between DCS supply and design, which seriously influence the DCS installation. (author)

[en] Objective: To explore the differences of clinical features and magnetic resonance imaging (MRI) manifestations between acute and chronic Budd-Chiari syndrome (BCS) in Chinese patients. Methods: The clinical data of MRI materials of 78 BCS patients, who were admitted to Zhejiang Hospital of China to receive treatment, were retrospectively analyzed. Based on the course of disease ≤ 6 months or > 6 months, the patients were divided into acute group (n = 32) and chronic group (n = 46). The clinical features and MRI manifestations were compared between the two groups. Results: In chronic group the patients were older than those in the acute group;the incidences of varicose vein of lower limb, lower limb swelling, lower extremity hyperpigmentation, subcutaneous varicose vein of abdominal wall were higher than those in the acute group; while the serum levels of hepatic function indexes, including ALT, AST and TBIL, were lower than those in the acute group; and the differences were statistically significant between the two groups (P < 0.05). When compared with the acute group, in the chronic group MRI showed less amount of ascites, lower incidence of liver enlargement, higher incidence of hepatic caudate lobe enlargement, more intrahepatic nodules, and higher incidence of intrahepatic-extrahepatic communicating branches and accessory hepatic veins;the differences in the above indexes between the two groups were statistically significant (P < 0.05). The main type of BCS in the acute group was hepatic vein type, while the main type of BCS in the chronic group was mixed type. On contrast-enhanced MRI, inhomogeneous hepatic parenchymal enhancement was often observed in the acute group, while homogeneous hepatic parenchymal enhancement was usually seen in the chronic group. Conclusion: Obvious differences in clinical features and MRI manifestations exist between acute and chronic BCS in Chinese patients. Understanding of these features and manifestations is helpful for making accurate staging and clinical diagnosis and treatment of BCS. (authors)

[en] We investigate the decay rate of an atom in a two-dimensional optical microcavity in which there exists a Bose-Einstein condensation of photons. It is found that below the critical temperature Tc, the atomic decay rate depends on the absolute temperature T. Especially, at absolute zero temperature almost all photons are in the condensate state, and the atom can be approximately treated as if it is in vacuum. (authors)

[en] Objective: To determine the value of MRI for diagnosing the posterior meniscus root tear. Methods: MR examinations of 30 patients with tear of the posterior meniscus root confirmed by knee arthroscopies were retrospectively reviewed. Of the 30 patients, 17 with posterior medial meniscus root tear (MMRT) and 13 with posterior lateral meniscus root tear (LMRT). The diagnostic sensitivity of' MRI for the posterior meniscus root tear was analyzed. Fisher's exact test was used to compare the detection rate of MRI for MMRT with that for LMRT. Results: All 17 cases with MMRT and 9 cases out of 13 with LMRT were correctly diagnosed by MRI and the diagnostic sensitivity of MRI for the posterior meniscus root tear was 86.7% (26/30). The main MR appearance of the posterior meniscus root tear was distortion of the meniscal root, with its low signal replaced by abnormal high signal. The detection rate of MRI for MMRT (17/17) was significantly greater than that for LMRT (9/13) (P=0.026). The prevalence of MMRT associated with meniscus extrusion (15/17) was significantly greater than that of LMRT (6/13) (P=0.020), but the prevalence of MMRT associated with anterior cruciate ligament (ACL) injury (5/17) was significantly lower than that of LMRT (11/13) (P=0.004). Conclusion: MRI is a relatively good method for detection of posterior meniscus root tears and associated injuries. (authors)

[en] The highly explored and studied southern Zhuguang granitic composite was used as the case for preliminary study on the application prospect of zircon uranium content in the exploration of granite uranium deposit. For this purpose, 21 samples of 3 types lithology from 10 U-deposit hosting pluton, 3 U-barren pluton was collected for the measurement of uranium content in zircons. Statistics of average uranium content in zircons showed that U-deposit bearing plutons have slightly higher zircons uranium content than that in U-barren pluton and there is no obvious difference of zircons uranium content between the deposit bearing and deposit barren pluton. The samples from different period and lithology in the deposit bearing pluton showed no higher average zircon uranium content than that in deposit barren plutons, the deposit bearing two-mica granite pluton of Indo-Chinese period even has less content than that in deposit barren granitic pluton of the same period. Meanwhile, the granite dikes in deposit bearing pluton have ultrahigh zircon uranium content (the average uranium content in zircons was more than 3000 × 10^-6). Therefore, the uranium content in zircons could not be used to evaluate the deposit bearing capacity in Zhuguang granitic composite, the high zircons uranium content in granite dike maybe the result of metallization and can be used as the sign for the indication of uranium deposits in this area.
