title: Theoretical study on the kinetics of the CF3O + NO reaction
title: Theoretical study on the kinetics of the CF3O + NO reaction

description: The rate constant for the CF3O + NO reaction has been studied with the variable reaction coordinate transitionstate theory and multichannel RRKM calculation based on the potential energy surface obtained by the G3B3//UB3LYP/6-311 + G(3df) level of theory. The total rate constant was found to exhibit weak negative temperature dependence, in line with most experimental results. The formation of FNO + CF2O is dominant at ambient temperature. The branching ratio of FNO + CF2O accounts for 0.922-0.618 at T = 150-3000 K peaking around 400 K. When temperature rises, the FON + CF2O channel becomes more and more appreciable, the branching ratio of FON + CF2O accounts for 0.001-0.382 at T = 150-3000 K increasing with temperature. At room temperature, the total rate constant is almost independent of the pressure, in agreement with previous experimental result.

title: Sequence-based Functional Metagenomics Reveals Novel Natural Diversity of Functioning CopA in Environmental Microbiomes
title: 序列功能宏基因组学揭示环境微生物中功能性CopA自然多样性

description: In this study, we developed a sequence-based functional metagenomics procedure for mining the diversity of copper resistance gene copA in global microbiomes, by combining the metagenomic assembly technology, local BLAST, evolutionary trace analysis (ETA), chemical synthesis, and conventional functional genomics. In total, 87 metagenomes were collected from a public database and subjected to copA detection, resulting in 93,899 hits. Manual curation of 1214 hits of high-confidence led to the retrieval of 517 unique CopA candidates, which were further subjected to ETA. Eventually, 175 novel copA sequences of high-quality were discovered. Phylogenetic analysis showed that almost all these putative CopA proteins are distantly related to known CopA proteins, with 55 sequences from totally unknown species. Ten novel and three known copA genes were chemically synthesized for further functional genomic tests using the Cu-sensitive Escherichia coli (ΔcopA). The growth test and Cu uptake determination showed that five novel clones had positive effects on host Cu resistance and uptake. One recombinant harboring copA-like 15 (copAL15) successfully restored Cu resistance of the host with a substantially enhanced Cu uptake. Two novel copA genes were fused with the gfp gene and expressed in E. coli for microscopic observation. Imaging results showed that they were successfully expressed and their proteins were localized to the membrane.

title: Metagenome-assembled genomes infer potential microbial metabolism in alkaline sulphidic tailings
title: 宏基因组分析推断碱性硫化物尾矿中潜在的微生物代谢

description: In this study, we detected a considerable amount of viable bacterial and archaeal cells using fluorescent in situ hybridization in alkaline sulphidic tailings from Mt Isa, Queensland. By taking advantage of high-throughput sequencing and up-to-date metagenomic binning technology, we reconstructed the microbial community structure and potential coupled iron and nitrogen metabolism pathways in the tailings. Assembly of 10 metagenome-assembled genomes (MAGs), with 5 nearly complete, was achieved. From this, detailed insights into the community metabolic capabilities was derived. Dominant microbial species were seen to possess powerful resistance systems for osmotic, metal and oxidative stresses. Additionally, these community members had metabolic capabilities for sulphide oxidation, for causing increased salinity and metal release, and for leading to N depletion.

title: High power femtosecond regenerative amplifier based on Yb: CaYAlO4 dual-crystal configuration
title: 基于双 Yb: CaYAlO4晶体结构的高功率飞秒再生放大器

description: A Yb: CaYAlO4 based thermal insensitive regenerative amplifier with dual crystal configuration for extending gain spectra is proposed and executed for the first time. By orthogonalizing the orientation of two a-cut Yb: CaYAlO4 crystals, the Q-switched spectrum with a central wavelength of 1035 nm and a spectral full width at half maximum of 15.4 nm is attained, which is 1.5 and 1.6 times of the Q-switched spectral bandwidth with π and σ polarization, respectively. The pulse energy of the seed is amplified to 1.5 mJ at 1 kHz repetition rate. By varying the repetition rate of the regenerative amplifier, the amplified power can exceed 10 W at the repetition rate of 20-800 kHz. Thanks to the design of the thermal insensitive dual crystal RA cavity and excellent thermodynamic properties of the Yb: CYA crystal, the amplified laser beam is near diffraction limit with an M2 value of 1.07×1.07. A compressed pulse of 218 fs with 92% overall efficiency is realized. The presented results show that Yb: CaYAlO4 crystal has great potential to generate high energy and high-power femtosecond pulses with sub-120 fs pulse duration.

title: Cadmium-Resistant Oyster Mushrooms from North China for Mycoremediation
title: 中国北方地区抗镉平菇筛选与表征

description: This study aimed to screen for cadmium (Cd)-tolerant oyster mushroom strains which may be used as biomaterials for Cd remediation in North China. To this end, 43 oyster mushroom strains were collected across North China and subject to Cd inhibition test. Phylogenetic affiliation of the tolerant strains was identified using molecular fingerprinting, and representative Cd-tolerant strains were characterized in terms of their Cd sorption capacity. Two strains, JINONG21 and SUYIN6 affiliated with Pleurotus ostreatus, were found to be highly tolerant to Cd, with a minimal inhibitory concentration of 4 mg L−1 Cd and a maximal tolerant concentration of 80 mg L−1 Cd under the test conditions. Meanwhile, JINONG21 and SUYIN6 were able to absorb up to 676 mg kg−1 and 970 mg kg−1 Cd in their mycelia in the culture medium with 20 mg L−1 Cd, respectively.

title: Opto-Mechanical Assembly and Analysis of Imaging Spectrometer
title: Opto-Mechanical Assembly and Analysis of Imaging Spectrometer

description: The imaging spectrometer developed by ourselves was introduced. The design of the optical machine and the adjustment of the optical machine were discussed. The results of the spectral test were analyzed. The instrument's spectral range is 400-1050nm, and its optomechanical part is mainly composed of hood, instrument frame, imaging system, spectroscopic system and detection system. According to the design requirements, an off-axis three-reverse imaging system was adopted, and a single aspherical mirror system was selected through MTF test comparison analysis. The Offner spectroscopic system was chosen considering factors such as image quality and compactness. The detection system uses a surface array CCD camera. The assembly test of each component system of the optical machine part was carried out separately. Finally, the instrument was tested by mercury argon lamp. The test results show that the spectral resolution of the imaging spectrometer is less than 7nm, which is better than the design index of 10nm, which has achieved the expected goal. It also verifies the design of the optical machine and the adjustment of the optical machine.

The comparison of the pre and post unit achievement tests indicated that the average test scores of both groups were increased significantly. Average post-test score of the experimental group was significantly higher than the control group. The effect size was strong with Cohen (d) coefficient calculated as 1,809059. Student interviews also support the findings. It was concluded that the sample unit and similar plans have potential to support student comprehension and unit achievement scores.
