This study investigated the effects of chlorine-based fertilizers under varying nitrogen solution concentrations in a soilless culture system. The experiment included four nitrogen solution concentration levels, with nitrogen concentrations of 6 mmol/L (C1), 12 mmol/L (C2), 18 mmol/L (C3), and 24 mmol/L (C4). Each nutrient concentration level was further divided into four chloride ion treatments (R1, R2, R3, and R4), where 100%, 60%, 33%, and 0% of the NH4+ and K+ ions were derived from NH4Cl and KCl, respectively. The length, surface area and volume of root were significantly higher by 25.3%~136.9%, 40.1%~173.1%, 27.9%~178.0%, respectively, in the R4 treatment than in the R1 and R2 treatments at flowering stage. The aboveground biomass and yield in the R4 treatment were significantly higher, by approximately 15.6%~43.5% and 16.6%~28.6%, respectively, than in the R1, R2, and R3 treatments at the picking stage. The C3 and C4 treatments significantly decreased biomass and yield by 31.9%~50.2% and 20.7%~50.5%, respectively, compared to the C1 and C2 treatments at the picking stage. Besides, the higher nutrient solution increased the incidence of blossom-end rot. In conclusion, high concentrations of chloride ions in nutrient solutions, especially when the Cl− concentration exceeded 10 mmol/L, have been shown to inhibit tomato growth in soilless culture systems. Therefore, replacing sulfur-based fertilizers by chlorine-based fertilizers is not recommended for tomato production under the studied conditions.

Synthesis,Crystal Structure and Antitumor Activity of a Novel Zn(Ⅱ)Complex with 2-(Nicotinoyloxy)acetic Acid Ligand

引用

Chinese Journal of Structural Chemistry 2018年第7期37卷 1052-1056页

作者：台夕市郭洪梅郭芊沁 college of Chemistry and Chemical Engineering Weifang University Department of Veterinary Medicine Shandong Vocational Animal Science and Veterinary College weifang No.1 Middle School

A novel Zn（Ⅱ） complex, [ZnL2（H2O）4]·H2O（1, HL = 2-（nicotinoyloxy）acetic acid）, was synthesized using Zn（OAc）2·2H2O and 2-（nicotinoyloxy）acetic acid as raw materials. Its structure has been elucidated by elemental analysis, IR and single-crystal X-ray diffraction. The structural analysis revealed that complex 1 crystallizes in triclinic, space group P1 and the Zn（Ⅱ） atom is six-coordinated with two N atoms from two different 2-（nicotinoyloxy）acetate anion ligands and four O atoms from coordinated water molecules. Complex 1 forms a 3D network structure by O–H···O hydrogen bonds. The antitumor activities of 2-（nicotinoyloxy）acetic acid ligand and its Zn（Ⅱ） complex were evaluated against human lung adenocarcinoma A549 cells, human hepatoma SMMC-7721 cells and human colon carcinoma Wi Dr cells.

Phase behavior and properties of salt-free cationic/anionic surfactant mixtures of oleic acid and stearic acid

引用

Chinese Science Bulletin 2009年第21期54卷 3953-3957页

作者： ZHAO DianYing LI HongGuang SONG AiXin HAO JingCheng Key Laboratory of Colloid and Interface Chemistry Ministry of Education Shandong University Jinan 250100 China weifang vocational college Weifang 261041 China

Cationic base surfactant, tetradecyltrimethylammonium hydroxide (TTAOH), can be obtained through anion exchange from tetradecyltrimethylammonium bromide (TTABr). Salt-free cationic and anionic (catanionic) surfactant mixtures were studied by mixing TTAOH with oleic acid (OA) or stearic acid (SA) in water. The phase behavior of TTAOH/OA/H2O is compared with that of TTAOH/SA/H2O. It was found that the phase behavior of TTAOH/OA/H2O and TTAOH/SA/H2O system differs from each other due to the existence of the unsaturated double carbon bond (C=C) in OA. At fixed total surfactant concentration (25 mg/mL) of TTAOH/OA/H2O system at 25℃, one can observe an isotropic L1 phase, and a L1/Lα two-phase region with increasing OA content. The volume of top turbid Lα phase increases while the bottom phase changes gradually from transparently clear to a bit turbid until a single Lα-phase is reached. Finally at high OA concentration, excess OA is separated from the bulk aqueous solutions. TTAOH/SA/H2O system usually forms white precipitating at 25℃ due to the high chain melting temperature of SA. When heated to 60℃, however, the state of samples changes. At fixed total surfactant concentration of 25 mg/mL, an isotropic L1 phase and a milk-white or bluish Lα-phase are observed with increasing SA concentration. Transparent thin layers which are strongly birefringent form at the tops of some samples within the Lα-phase region. Finally, at high SA concentration, excess SA is separated from the bulk aqueous solutions. In addition to phase behavior study, we also measured the conductivity of TTAOH/OA/H2O system at 25℃ and TTAOH/SA/H2O system at 60℃, respectively. Surface tension and rheological measurements were also performed on typical samples.

Microstructure and wear resistance of Fe-Cr-Ti-C reactive plasma cladding coating

China Welding 2012年第3期21卷 22-26页

作者：刘均波韩德伟刘均海 School of Mechanical-electronic and Vehicle Engineering Weifang UniversityWeifang261061 Department of Mechanical and Electronic Engineering Weihai Vocational CollegeWeihai264210

Fe-Cr-Ti-C composite powder was synthesized by precursor carbonization-composition process using the mixture of ferrotitanium, chromium, iron powder and precursor sucrose as raw material. And then the Fe-Cr-Ti-C coating was prepared by reactive plasma cladding method. Microstructure of the samples was observed by scanning electron microscope （SEM）, the phases were determined by X-ray diffraction （XRD）, and the wear resistance was evaluated under dry sliding wear test conditions at room temperature. Results indicate that the composite coating consists of primary austenite and dendritic eutectic austenite, chrysanthemum-shaped eutectic （Cr, Fe ） 7 C3 and TiC carbide. TiC presents the gradient distribution and different shapes in the coating, corresponding to equiaxial structure both in fusion zone and central zone, while it presents dendritic structure on the surface, respectively. The wear mass loss is insensitive to load for the coating while it increases rapidly for Q235 steel base metal in this test. The wear mass loss ofQ235 steel is 14 times as that of the composite coating under applied load of 40 kg.
