Pillar-Layered Strategy to Design and Synthesis of Two Mofs with Excellent C2h2 Capture and C2h2/Co2 Separation Capability

Yunling Liu Wen Li Jianyun Li Borong Zhang Zhaohui Shi

Acetylene and carbon dioxide share similar physical properties, which poses a significant challenge for their industrial separation. Therefore, it is crucial to design and synthesize specific physical adsorbents for this purpose. In this study, two pcu topological MOFs materials named JLU-MOF102 {[Ni(HPyC)2(BPY)] (DMF)2(H2O)2} and JLU-MOF103 {[Ni(HPyC)2(PYZ)] (H2O)2} (4-pyrazolecarboxylic acid = H2PyC, 4,4’-bipyridine = BPY, pyrazine = PYZ, DMF = N, N- dimethylformamide), were successfully synthesized to facilitate the separation of C2H2 and CO2. These MOFs were synthesized by using the pillar-layered strategy, both having the same sql layer (combined Ni2+ and HPYC) but different pillar ligands (BPY for JLU-MOF102 and PYZ for JLU-MOF103, respectively). The pore size of JLU-MOF103 is smaller than that of JLU-MOF102 and the interaction between JLU-MOF103 and C2H2 molecules is stronger. JLU-MOF102 and JLU-MOF103 exhibit significant ability to capture C2H2 (125.8 and 96.7 cm3/g, respectively) and the selectivity for C2H2/CO2 (v/v = 50/50) mixture is 4.5 and 14.0 calculated by IAST, respectively, at 298 K and 1 bar. First-principles-based calculations reveal subtle differences in host-guest interactions between JLU-MOF102 and JLU-MOF103 originated from the porous structures, which account for their distinct separation selectivity. The dynamic column breakthrough experiments demonstrated that JLU-MOF103 had a higher C2H2 adsorption capacity of 2.01 mmol/g compared to JLU-MOF102 (1.16 mmol/g). The low cost, excellent stability and good recycling ability suggest the potential of JLU-MOF103 for industrial applications.

Effect of potassium on nitrogen and phosphorus utiliozation by wheat different varieties

Jianyun Li Jie Xiao-lei Tan Jin-fang Xinming Wang Hou Yan-lin

We studied nitrogen and phosphate absorption and utilization under two potassium levels by pot culture. Results showed that there were great differences in nitrogen and, phosphate use ability among wheat varieties.The N and P accumulation amounts were positively correlated with dry matter accumulation,and the correlation analysis also showed that high potassium wheat varieties are also high nitrogen and high phosphate wheat varieties.

Effect of Ultra-Fine Cement on the Strength and Microstructure of Humic Acid Containing Cemented Soil

Sustainability (2023)

Jing Cao Fangyi Liu Zhigang Song Wenyun Ding Yongfa Guo

The peat soil in the Dianchi Lake area of Yunnan, China, is widely distributed, bringing many problems to engineering. The peat soil foundation is usually treated by the cement mixing method, and the reinforcement effect of cemented soil is mainly affected by humic acid (HA). Ultra-fine cement (UFC) can improve cement performance and reduce cement consumption, decreasing CO2 emissions and the impact of human activities on the environment. Simulated peat soils in different environments are prepared with HA reagent and cohesive soil, reinforced by composite cement curing agent mixed with ultrafine cement (UFC). The relationship among the UFC proportion, HA reagent content, soaking time, and sample strength was studied. The unconfined compressive strength test (UCS), scanning electron microscope (SEM), and PCAS microscopic quantitative test techniques were used to explore the mechanism of the effect of UFC on the strength of HA-containing cemented soil. The increasing UFC proportion in the composite cement curing agent gradually increased HA-containing cemented soil’s strength. UFC significantly reduced the percentage of macropores in HA-containing cemented soil and made the microstructure denser. The HA-containing cemented soil’s qu increased the most when the UFC proportion increased from 0% to 10%. The solidification effect of the composite cement curing agent mixed with UFC was always stronger than that of OPC. The composite cement curing agent with a UFC proportion of 10% is practical. Cement is still an important building material in the current construction industry, and UFC provides a new method for reducing environmental impact in engineering construction.

Optimization of plastics injection molding processing parameters based on the minimization of sink marks

International Conference on Mechanic Automation and Control Engineering (2010)

Longzhi Zhao Chen Bing-hui Jianyun Li Zhang Shang-bing

In order to avoid the surface sink marks on the automobile dashboard decorative covers, the combined effects of multi-molding process parameters are analyzed by the combination of orthogonal experiments and Moldflow simulation tests. By this method, it can gain the experiment data which can reflect the overall situation using fewer number of simulation test. Furthermore, the effects degree of different molding process parameters for surface sink marks are investigated, and the reasonable gate location and optimized parameter combination is obtained. It can solve the unreasonable appearance of process parameter settings. The mold design above mentioned can fasten the mold developing schedule, thus shorten the cycle of product development, and improve the quality of products and the competitive ability of enterprise.
