Fluorescent silicon nanoparticles (SiNPs) bring exciting opportunities for long-awaited silicon-based optical application, while intrinsic indirect band gap of silicon severely limits photoluminescent quantum yield (PLQY) of SiNPs. To address this critical issue, we herein demonstrate a facile and general method, Le., solvent polarity-induced photoluminescence enhancement (SPIPE)1 yielding several-fold increase in quantum yield (QY) of SiNPs. Typically, different kinds of 4-substituented-1,8-naphthalic anhydride molecules, Le., 4-Br-1,8-naphthalic anhydride (BNA)1 4-triphenylamino-1,8-naphthalic anhydride (TPNA)1 and 4-dimethylamino-1,8-naphthalic anhydride (DMNA)1 are rationally designed and synthesized, which serve as surface ligands for the production of BNA-, TPNA-, and DMNA-capped small-sized (diameter:- 3.8-5.8 nm) SiNPs with QY of^8%,~15%,~16%, respectively. Of particular significance, QY of the resultant SiNPs could be greatly enhanced from^10% to^50% through the SPlPE strategy. Taken together with the theoretical calculation and the results of time-correlated single photon counting, we reveal that actived excited-state charge transfer interactions between surface-covered ligand and silicon oxide coating would be responsible for the observed QY enhancement. Moreover, other five kinds of solvents (i.e., methanol, isopropanol, dimethyl sulfoxide, N,N-dimethylformamide, and acetonitrile) are further employed for the SiNPs treatment, and similar improvement of QY values are observed, convincingly demonstrating the universal evidence of SPIPE of the SiNPs.

Objective： To investigate the time and postoperative binocular vision of strabismus surgery for children with intermittent exotropia （X（T））. Methods： A retrospective investigation was conducted in 80 child patients with intermittent exotropia. Pre- and postoperative angles of deviation fixating at near （33 cm） and distant targets （6 m） were measured with the prolonged alternate cover testing. The binocular function was assessed with synoptophore. Twenty-one patients took the postoperative synoptophore exercise. Results：（1） A week after surgery, 96.2% of the 80 patients had binocular normotopia, while a year after surgery, 91.3% of the 80 patients had binocular normotopia; （2） Preoperatively, 58 patients had near stereoacuity, while postoperatively, 72 patients achieved near stereoacuity （P〈0.05）; （3） Preoperatively, 64 patients had Grade Ⅰ for the synoptophore evaluation and postoperatively, 76 patients achieved Grade Ⅰ. Meanwhile, 55 patients had Grade Ⅱ preoperatively and 72 achieved Grade Ⅱ postoperatively. For Grade Ⅲ, there were 49 patients preoperatively and 64 patients postoperatively （P〈0.05）; （4） Patients of 5-8 years old had a significantly better recovery rate of binocular vision than those of 9-18 years old （P〈0.05）; （5） Patients taking postoperative synoptophore exercise had a better binocular vision than those taking no exercise （P〈0.05）. Conclusions：（1） Strabismus surgery can help to preserve or restore the binocular vision for intermittent exotropia; （2） Receiving the surgery at young ages may develop better postoperative binocular vision; （3） The postoperative synoptophore exercise can help to restore the binocular vision.

In order to study the structure of neutralino star and dark galaxy, we consider dynamical interactions due to boson-exchange in the neutralino matter. Taking into account interactions of neutralinos with bosons, we derive the equation of state （EOS） of neutralino stars in terms of the relativistic mean-field approach. Then we apply the resulting EOS to investigate properties of the neutralino star such as its density profile and mass limit. For example, if the neutralino mass is around 1 TeV, the Oppenheimer mass limit of the neutralino star is obtained as 6.06 ×10^-7 M⊙, and the corresponding radius is about 7.8 mm. Actually, due to an increasing annihilation rate as indicated by our calculation, this dense state can never be realized in practice. Our results also show that the low-density neutralino star may be a possible aggregation of the cold dark matter.

As of August 30,2021,COVID-19 has caused more than 216 million infections and 4.49 million deaths worldwide,with 0.58 million new cases[1].Because the COVID-19 vaccine is distributed gradually and widely,the development of the global epidemic has been prevented to some extent,but the emergence of SARS-CoV-2 variants makes us *** alpha(B.1.1.7),beta(B.1.351),gamma(P.1)and delta(B.1.617)strains have been named variants of concern by the WHO[2].The SARS-CoV-2 variants have increased in transmissibility and virulence,leading to higher morbidity and mortality.

To study the influence of human activity on natural lake, chironomid fauna change in the 700-560cm lake sediment in Quidenham Mere of England associated with chironomid inferred TP presented that the lake experienced a whole eutrophication process due to human hemp-retting in Post-Medieval based on the history record and pollen analysis, which was confirmed by mollusc and ostracod analysis. However, the response of chironomid and mollusc to retting was the strongest with ostracod a little behind. It proved that cultural eutrophication existed in history and could be recovered by itself despite of some long-term unachievahle destroy. And it was most important for external nutrient to be cut off during lake restoration even in ancient times.

Crystal plasticity theory was used to simulate upsetting tests of different dimensions and grain size micro copper cylinders in this study on the fluctuant flow stress scale effect. Results showed that with the decrease of billet grain quantity, flow stress fluctuation is not always increased, but there is a maximum. Through this study, the fluctuant flow stress scale effect can be understood deeper, and relevant necessary information was obtained for further prediction and control of this scale effect and to design the microforming process and die.
