Polyimide–polydimethylsiloxane copolymers for low‐dielectric‐constant and moisture‐resistance applications

Journal of Applied Polymer Science (2009)

Kai Xi Zhen Meng Liang Heng Renjie Ge Hui He

Abstract Novel, randomly coupled, soluble, segmented polyimide–polydimethylsiloxane (PI–PDMS) copolymers were prepared from aminoalkyl‐terminated polydimethylsiloxane (At–PDMS), 4,4′‐oxydianiline diamine, pyromellitic dianhydride, and 4,4′‐diphenylmethane diisocyanate (MDI). When At–PDMS was introduced into the polyimide chain, the polyimide copolymers exhibited lower dielectric constants and better moisture resistance and mechanical properties. The reductions in the dielectric constant of the PI–PDMS copolymers could be attributed to the incorporation of polydimethylsiloxane (PDMS) into the polyimide chain and the nanopores in the film generated by carbon dioxide evolvement during the reaction. The lowest dielectric constant was 2.58 with 25 wt % PDMS and 5 wt % MDI. In addition, the water contact angles of the resultant copolymers increased from 51 to 109° when the contents of PDMS increased from 0 to 25 wt %. © 2009 Wiley Periodicals, Inc.

N-Phenylaminomethyl hybrid silica, a better alternative to achieve reinforced PU nanocomposites

RSC Advances (2014)

Qiuhong Zhang Xin Huang Zhen Meng Xudong Jia Kai Xi

A novel NPAM-silica was synthesized by an economic and environmentally friendly method. It was chemically cooperated into polyurethane with enhanced mechanical properties. Compared with N-phenylaminomethyl POSS/PU composites, the crosslinking junction states and the mechanical properties are different. NPAM-silica provided a better alternative for polymer/nanocomposites.

Genetic association of lipids and lipid-lowering drug target genes with non-alcoholic fatty liver disease

EBioMedicine (2023)

Ziang Li Bin Zhang Qing‐Rong Liu Zhihang Tao Lu Ding

Some observational studies found that dyslipidaemia is a risk factor for non-alcoholic fatty liver disease (NAFLD), and lipid-lowering drugs may lower NAFLD risk. However, it remains unclear whether dyslipidaemia is causative for NAFLD. This Mendelian randomisation (MR) study aimed to explore the causal role of lipid traits in NAFLD and evaluate the potential effect of lipid-lowering drug targets on NAFLD.Genetic variants associated with lipid traits and variants of genes encoding lipid-lowering drug targets were extracted from the Global Lipids Genetics Consortium genome-wide association study (GWAS). Summary statistics for NAFLD were obtained from two independent GWAS datasets. Lipid-lowering drug targets that reached significance were further tested using expression quantitative trait loci data in relevant tissues. Colocalisation and mediation analyses were performed to validate the robustness of the results and explore potential mediators.No significant effect of lipid traits and eight lipid-lowering drug targets on NAFLD risk was found. Genetic mimicry of lipoprotein lipase (LPL) enhancement was associated with lower NAFLD risks in two independent datasets (OR1 = 0.60 [95% CI 0.50-0.72], p1 = 2.07 × 10-8; OR2 = 0.57 [95% CI 0.39-0.82], p2 = 3.00 × 10-3). A significant MR association (OR = 0.71 [95% CI, 0.58-0.87], p = 1.20 × 10-3) and strong colocalisation association (PP.H4 = 0.85) with NAFLD were observed for LPL expression in subcutaneous adipose tissue. Fasting insulin and type 2 diabetes mediated 7.40% and 9.15%, respectively, of the total effect of LPL on NAFLD risk.Our findings do not support dyslipidaemia as a causal factor for NAFLD. Among nine lipid-lowering drug targets, LPL is a promising candidate drug target in NAFLD. The mechanism of action of LPL in NAFLD may be independent of its lipid-lowering effects.Capital's Funds for Health Improvement and Research (2022-4-4037).

Hydrophilic or Hydrophobic? Optimizing the Catalyst Microenvironment for Gas‐Involving Electrocatalysis

ChemCatChem (2023)

Kaige Shi Zhuanghe Ren Zhen Meng Xiaofeng Feng

Abstract Electrocatalysis plays a key role in the development of renewable energy technologies. Along with the design of electrocatalysts, the microenvironment around catalytic sites has received increasing attention because it affects the distribution and mass transport of reaction species and impacts the reaction kinetics. In this Concept article, we highlight some mechanistic insights into the effect of microenvironment on gas‐involving electrocatalytic reactions, including CO 2 reduction, 2‐electron oxygen reduction, and hydrazine oxidation, demonstrating their sensitivity to the wetting properties of microenvironment. For reactions with a gaseous reactant, a moderately hydrophobic microenvironment can greatly enhance the mass transport of gaseous species to accelerate the reaction kinetics while improving the stability of gas‐diffusion electrodes. In contrast, for reactions with a liquid reactant and gaseous product, a hydrophilic microenvironment improves the exposure of catalytic sites to the reactant, while a hydrophobic microenvironment benefits the reaction on the other end by accelerating the diffusion and detachment of generated gas bubbles, which would otherwise block the catalytic sites from the reactant. These understandings and insights can provide important guidelines on the control and optimization of catalyst microenvironment for the development of efficient electrolyzers.

Complete Single-Pass Conversion of Dilute Nitrate to Ammonia Using Cu/Co(OH)₂ Tandem Electrocatalyst

ACS Energy Letters (2024)

Zhuanghe Ren Kaige Shi Zhen Meng Maia D. Willis Xiaofeng Feng

Electrochemical nitrate reduction reaction (NO3RR) provides a promising route for the denitrification of wastewater and sustainable NH3 production but requires active and selective electrocatalysts. Here, we demonstrate a rigorous design of a tandem electrocatalyst for efficient conversion of NO3– to NH3. Based on the screening of tandem components, a catalyst coupling Cu and Co(OH)2 with an optimal ratio and tandem architecture was developed to promote and balance the activities of sequential NO3RR steps on different active sites. Compared to counterpart catalysts including Cu, Co(OH)2, and Cu–Co alloy, the Cu/Co(OH)2 catalyst with separated phases showed much higher activity and selectivity for the NO3RR to NH3, suggesting a tandem mechanism that involves NO3– reduction to NO2– on Cu and solution transfer and further reduction of NO2– to NH3 on Co-based sites. When operated in a flow cell, the Cu/Co(OH)2 catalyst achieved 100% single-pass conversion of dilute NO3– solution to NH3 at low overpotentials.
