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：
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.

摘要：
A series of polyimide composites with various mass fractions of multi-walled carbon nanotubes (MWNTs) were prepared by in situ polymerization. To increase the chemical compatibility of carbon nanotubes with the polyimide matrix, MWNTs were treated with an acid mixture and sulfoxide chloride in turn. The modified MWNTs are dispersed homogeneously in the matrix while the structure of the PI and MWNTs are stable in the preparation process. The composite films hold preferable thermal stability the same as the pure PI. The composite films exhibited good thermomechanical properties. The storage modulus increased significantly by increasing MWNT content and decreasing the enhancement of temperature. The films' glass transition temperature increased with enhancing of MWNTs frictions. The dielectric constants of the composites decrease with increasing frequency and increase sharply with the adding of MWNTs, which is favorable for practical use in anti-static materials and embedded capacitors.

摘要：
p-Aminothiophenol (PATP) and humic acids (HA or HAs) were applied jointly as the electron transfer accelerants of redox reactions of cytochrome c (Cyt c) on gold electrodes. The electrochemical properties of the modified electrodes were studied by field emission scanning electron microscope, ultraviolet-visible spectroscopy, electrochemical impedance spectroscopy, Raman spectroscopy and cyclic voltammetry. The immobilized Cyt c displayed a couple of stable and well-defined redox peaks with a formal potential of -0.101 V (vs. SCE) in pH 7.0 phosphate buffer solution. Cyt c adsorption is in the form of a monolayer with average surface coverage of 5.28 pmol cm-2. The electron transfer rate constant was calculated to be 2.14 s-1. It indicate that the HA film acted as a good adsorption matrix for Cyt c and an excellent accelerant for the redox of Cyt c. The Cyt c-HA modified gold electrode showed a new couple of well-marked redox peaks when 2,4-dichlorophenol was added to the test solution. © 2006 Springer-Verlag.

摘要：
An amperometric immunosensor was constructed by dispersing graphite, schistosoma-japonicum antigen (SjAg) and silica sol-gel at low temperature. The performance characteristics of the prepared immunosensor were examined in the buffered solution of o-aminophenol (o-AP) used as a substrate. It exhibited excellent physical and electrochemical stability with a renewable external surface. A competitive binding assay was employed to determine schistosoma-japonicum antibody (SjAb) with the aid of horseradish peroxidase labeled SjAb (HRP-SjAb). The experimental parameters for SjAb assay were optimized, including the amount of labeled SjAb in incubation solution, incubation time, temperature and the pH of solution. The use of o-AP substrate and amperometric detection at -250 mV (vs. SCE) results in a determination limit of 0.32 μg/ml and a linear range extending up to 0.18 μg/ml. The results of SjAb assay in serum samples demonstrate the feasibility of using the proposed immunosensor for clinical analysis.

摘要：
1 INTRODUCTION
Catalytic hydrodechlorination is an elegant reaction for disposal of environmentally hazardous chlorocarbons,such as chloro-benzene[1].Development of a new catalyst with excellent stability is necessary due to the deactivation of supported noble metal catalysts[1].However the modification of catalytic properties of catalysts in hydrodechlorination reaction by introducing stable ligands to noble metals has been the least studied.Here the synthesis of Pd(Ⅱ) 2,9,16,23-symetrically tetrasubstituted phthalocyanines PdPTX4 (where X=-H,-NO2,-NH2 respectively) from phthalimide derivatives is reported,and their application as catalysts in hydrodechlorination of chlorobenzene,which is a representative environmentally hazardous materials is discussed.
