Crystal Engineering of Naphthalenediimide-Based Metal-Organic Frameworks: Structure-Dependent Lithium Storage.

Metal-organic frameworks (MOFs) possess great structural diversity because of the flexible design of linker groups and metal nodes. The structure-property correlation has been extensively investigated in areas like chiral catalysis, gas storage and absorption, water purification, energy storage, etc. However, the use of MOFs in lithium storage is hampered by stability issues, and how its porosity helps with battery performance is not well understood.

Networked Spin Cages: Tunable Magnetism and Lithium Ion Storage via Modulation of Spin-Electron Interactions.

A networked spin cage comprising infinite CoL cages arrays (where Co = Co(NCS) and L = 1,3,5-tri-(4-pyridyl)-verdazal radical) is synthesized and found to exhibit tunable magnetic and electrochemical properties via inclusion of guests. SQUID investigation reveals the coexistence of ferromagnetic and anti-ferromagnetic interactions between the Co(II) ion center and radical ligands. Inclusion of electron-deficient guests (e.

[Input and distribution of rice photosynthesized carbon in the tillering stage under different nitrogen application following continuous 13C labeling].

The input of rice-photosynthesized carbon (C) into soil plays an important role in soil C cycling. A 13C-labelled microcosm experiment was carried out to quantify the input of photosynthesized C into soil C pools in a rice-soil system during the tillering stage. Growing rice (Oryza sativa L.

[Dynamics of the mineralization and transformation of rice photosynthesized carbon in paddy soils--a batch incubation experiment].

Photosynthesized carbon is an important part in C cycling of "atmosphere-plant-soil" and is the source of soil organic carbon (SOC), but its mineralization and transformation dynamics in paddy soils remains still unclear. Therefore, a batch incubation experiment was conducted to investigate the mineralization and transformation of rice photosynthesized carbon in paddy soils after rice harvest. The results showed that the mineralization rate of native SOC ranged from 4.

Continuous flow Sonogashira C-C coupling using a heterogeneous palladium-copper dual reactor.

We report the development of a heterogeneous catalyst system on continuous flow chemistry. A palladium (Pd) coated tubular reactor was placed in line with copper (Cu) tubing using a continuous flow platform, and a Sonogashira C-C coupling reaction was used to evaluate the performance. The reactions were favorably carried out in the Cu reactor, catalyzed by the traces of leached Pd from the Pd reactor.

Migration kinetics and mechanisms of plasticizers, stabilizers at interfaces of NEPE propellant/HTPB liner/EDPM insulation.

Migration appeared in the interfaces of nitrate ester plasticized polyether (NEPE) based propellant/hydroxyl-terminated polybutadiene (HTPB) based liner/ethylene propylene terpolymer (EPDM) based insulation was studied by aging at different temperatures. The migration components were extracted with solvent and determined by high performance liquid chromatography (HPLC). The migration occurred within 1mm to the interfaces, and the apparent migration activation energy (Ea) of nitroglycerin (NG), 1,2,4-butanetriol trinitrate (BTTN) and a kind of aniline stabilizer AD in propellant, liner and insulation was calculated respectively on the basis of HPLC data.

[The relationship between ApoE gene polymorphism and lipid parameters].

Objective: To investigate the relationship between apolipoprotein E (ApoE) gene polymorphism and serum lipid profile.

Methods: Polymerase chain reaction-restricted fragments length polymorphism (PCR-RFLP) was used to determine ApoE genotype on 1452 subjects including 1101 cases with cardio cerebrovascular disease including 379 cases with cerebral infarction, 313 cases with cerebral hemorrhage, 257 cases with coronary heart disease, and 152 cases with other types and on 351 healthy controls.

Results: After adjusting for age, sex and BMI, the subjects with ApoE4 carriers had significantly higher levels of total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) and ApoB than those with ApoE2 carriers and ApoE3/3 (P < 0.

Effect of the interaction between paranoxonase 1 and ATP-binding cassette transporter 1 gene polymorphism on serum lipid level.

Objective: To investigate the effect of interaction between paranoxonase 1 (PON1)gene polymorphism and ATP-binding cassette transporter 1 (ABCA1) genetic variation on serum lipid level.

Methods: Polymerase chain reaction-restricted fragments length polymorphism was used to determine PON1 A/B192 and ABCA1R219K genotype of 1019 subjects, including 680 patients with strokes and 339 healthy individuals as controls.

Results: No significant association between A/B192 genotype and any of the lipid measurements was detected.

[Relationship between ATP-binding cassette transporter 1 R219K genetic variation and blood lipids].

Objective: To investigate whether ATP-binding cassette transporter 1 (ABCA1) R219K genetic variation is correlated with blood lipids.

Method: Specimens of peripheral blood were collected from 692 patients with cerebral apoplexy, aged 62 +/- aged 12, and 352 sex- and age-matched persons without cardio-cerebro-vascular disease. Polymerase chain reaction-restricted fragments length polymorphism (PCR-RFLP) was used to determine the ABCA1 genotype: RR type (177 bp), RK type (177 bp, 107 bp, and 70 bp); and KK type (107 bp and 70 bp).
