摘要：
Abstract: In this paper, the content of free formaldehyde in large core board was successfully determined by perforated extraction and acetyl acetone spectrophotometry. In the environment of constant temperature shaking water bath and acetic acid-ammonium acetate buffer solution (pH = 6), formaldehyde reacts with acetyl acetone to produce a stable yellow compound 3-methylene-2, 4-pentanedione, which is then measured at a wavelength of 412 nm Its absorbance. The results show that when using perforated extraction and acetyl acetone spectrophotometry to determine the formaldehyde content in large core plates, the formaldehyde content has a good linear relationship with the absorbance in the range of 0~10 μg/ml, and its linear correlation coefficient (R)reaches 0.99872. The recovery rate of standard addition was 97.6%~99.7%, the average recovery rate of standard addition was 99.0%, and the detection limit was 0.0890 μg/ml. It can be seen that the method has high sensitivity and high accuracy, and can be applied to the determination of formaldehyde content in large core boards.#@#@#摘要: 本论文采用穿孔萃取法和乙酰丙酮分光光度法成功测定了大芯板中游离的甲醛的含量。甲醛与乙酰丙酮反应，产生稳定的黄色化合物3-亚甲基-2,4-戊二酮，再于波长412 nm处测定其吸光度。试验测得的板材中甲醛含量为0.0159 mg/m3。结果表明，利用穿孔萃取法和乙酰丙酮分光光度法测定大芯板中的甲醛含量时，甲醛含量在0~10 μg/ml范围内与吸光度呈现出良好的线性关系，其线性相关系数为r = 0.99872，加标回收率为97.6%~99.7%，平均加标回收率为99.0%，检出限为0.0890 μg/ml。由此可见，该法灵敏度较高，准确度较高，可适用于大芯板中甲醛含量的测定。

摘要：
Nowadays, resorcinol (RC) has been widely applied in the chemical and pharmaceutical industries. However, the electrochemical detection technique of RC still features some significant drawbacks, for instance, a low sensitivity. Hence, in the present work, a glass carbon electrode was developed for the electrochemical detection of RC with good specificity and stability, through modifying the glass carbon electrode (GCE) by polyphenol oxidase (PPO), an NH2- SBA-15 mesoporous material (NH2-SBA-15), L-tyrosine (L-Tyr) and gold nano-particles (AuNPs). After being successively modified by AuNPs, L-Tyr, NH2-SBA-15 and PPO, the constructed PPO/NH2-SBA-15/L-Tyr/AuNPs/GCE was used to discriminate RC from ions and other common micromolecules, which showed a fairly good specificity and stability. The proposed electrochemical detection method features a linear range of from 0.5 to 21.0 μM with a LOD down to 0.15 μM, revealing a better sensitivity than the existing methods. It is worth mentioning that the proposed PPO/NH2-SBA-15/L-Tyr/ AuNPs/GCE has been successfully used as an electrochemical probe for the RC assay in domestic sewage. 2021 © The Japan Society for Analytical Chemistry

摘要：
The installation of a HCF2 group is a research area that has received increasing attention, and deoxydifluorination of aldehydes have served as an attractive protocol due to the wide availability of aldehydes. Herein we describe a Ph2S/Selectfluor-promoted deoxydifluorination of aldehydes under mild conditions. Compared with previous deoxydifluorination methods, which usually use hazardous reagents such as SF4, DAST and Deoxo-Fluor, this protocol is quite attractive because of the safe and convenient operations, and the use of easily available reagents.

摘要：
A graphene (GN) and ionic liquid (IL) modified selenium-doped carbon paste electrode (GN/IL/Se/CPE) was established to simultaneously determine trace Cu(ii) and Sb(iii) by differential pulse voltammetry (DPV). Several parameters which affect the stripping current response were investigated and optimized, including the proportion of Se powder, concentration of hydrochloric acid, deposition time and deposition potential. The DPV curves were recorded by simultaneous deposition of Cu(ii) and Sb(iii) at -0.4 V for 50 s in a supporting electrolyte solution HCl of 0.30 mol L-1. Under the optimized conditions, the GN/IL/Se/CPE sensor has a good linear response in the range of 2.0 × 10-6 to 7.0 × 10-5 mol L-1 for Cu(ii) and 2.0 × 10-6 to 4.0 × 10-5 mol L-1 for Sb(iii). The detection limits were 6.6 × 10-7 mol L-1 for Cu(ii) and 4.3 × 10-7 mol L-1 for Sb(iii). The sensor showed favorable stability and higher sensitivity. The present work extends the scope of these devices as mercury-free sensors and can be used to detect Cu(ii) and Sb(iii) simultaneously. © The Royal Society of Chemistry 2016.

摘要：
Electrochemical performances of LiCoO2 as a candidate material for supercapacitor are systematically investigated. LiCoO2 nanomaterials are synthesized via hydrothermal reaction with consequent calcination process. And the particle size increases as the calcination temperature rises. LCO-650 sample with the largest particle size displays the maximum capacitances of 817.5 F·g-1 with the most outstanding capacity retention rate of 96.8% after 2000 cycles. It is shown that large particle size is beneficial to the electrochemical and structural stability of LiCoO2 materials. We speculate that the micron-sized waste LiCoO2 materials have great potential for supercapacitor application. It may provide a novel recovered approach for spent LIBs and effectively relieve the burdens on the resource waste and environment pollution. © 2015 Dalian Institute of Chemical Physics, the Chinese Academy of Sciences.

摘要：
A novel graft copolymer of poly(vinylidene fluoride-chlorotrifluoroethylene-trifluoroethylene)-graft-poly(6-((4-cyano-4-biphenyl)oxy) hexyl methacrylate) (P(VDF-CTFE-TrFE)-graft-PCBHM) using P(VDF-CTFE-TrFE) as the initiator was successfully synthesized via atom transfer radical polymerization. It was found that the crystallinity of resultant graft copolymer increased slightly after grafting from the P(VDF-CTFE-TrFE), and the crystalline regions in the graft copolymer contained more (β phase which has all-trans chain conformation) trans chain conformation. Upon the introduction of PCBHM side chains, the thermal stability of the graft copolymer was lower than that of pristine terpolymer, but the storage modulus was enhanced significantly, which is beneficial for breakdown field-strength enhancement, and dielectric properties simultaneously decreased. © 2014 Taylor & Francis.

摘要：
2LiBH4/MgH2 system is a representative and promising reactive hydride composite for hydrogen storage. However, the high desorption temperature and sluggish desorption kinetics hamper its practical application. In our present report, we successfully introduce CoNiB nanoparticles as catalysts to improve the dehydrogenation performances of the 2LiBH 4/MgH2 composite. The sample with CoNiB additives shows a significant desorption property. Temperature programmed desorption (TPD) measurement demonstrates that the peak decomposition temperatures of MgH 2 and LiBH4 are lowered to be 315 °C and 417 °C for the CoNiB-doped 2LiBH4/MgH2. Isothermal dehydrogenation analysis demonstrates that approximately 10.2 wt% hydrogen can be released within 360 min at 400 °C. In addition, this study gives a preliminary evidence for understanding the CoNiB catalytic mechanism of 2LiBH4/MgH2.
