The metallographic studies have indicated that the bonding phase of the WC-13%Fe/Co/Ni alloy with addition of small A1 is mainly of γ phase and lath martensite with partial existense of α+ (Fe,Me)_3C lamellar structure.
The experimental results showed that HSPS can improve the interfacial adhesion between PA1010 and PS phase and enhance their compatibility, resulting in the higher notched impact strength for PA1010/PS/HSPS ternary blends.
Comparing the bending experimental results of EZR-A1HSD and EZR-B2DSD toughening systems,it is believed when EZR-A1HSD toughening agent quantity is 15%,the adhesion between CFRP and concrete has the best properties. Therefore,the optimal toughening formulation of the adhesive materials is determined.
In the CoMSIA model, steric, electrostatic, hydrophobic and hydrogen bond donating factors were correlated to the activity and later the favorable and unfavorable regions of interaction were obtained.
The aim of this work was the synthesis of a new family of lactosylated piperazinly porphyrins in which the galactoside piperazine moieties are linked to the tetra- and monophenyl ring by an amide bond.
A fixed double (single) bond of a Kekuléan benzenoid systemH is an edge belonging to all (none) of the Kekulé structures ofH.
In this paper a generalized defaultable bond pricing formula is derived by assuming that there exists a defaultable forward rate term structure and that firms in the economy interact when default occurs.
This paper proves that multiple default intensities are invariant under equivalent martingale transformation, given a well-diversified portfolio corresponding to the defaultable bond.
tripos standard, hydrogen bonding, parabolic indicator in the case of CoMFA and steric, electrostatic, donor, acceptor, hydrophobic, donor and acceptor, steric and electrostatic in the case of CoMSIA.
In addition, electrostatic, hydrogen-bonding, and dipole-dipole interactions are responsible for the above separations, which improve the selectivity of DNB for solutes.
For example, in water, PCL and PAA formed core-shell nanospheres due to interpolymer hydrogen bonding.
Both the micellization and the structure transition were found to be reversible and associated with H-bonding complexation between the main chain and grafts.
When the content of nano-SiO2 was below 1.5%, the amount of free formaldehyde decreased, and the viscosity and bonding strength of resin increased with an increase in the added nano-SiO2, which did not prolong the curing time.
Preparation and Evaluation of 3,5-Dinitrobenzoyl-Bonded Silica Gel Stationary Phase for HPLC
In this paper, a new preparation method of 3,5-dinitrobenzoyl-bonded silica gel stationary phase (DNB) for HPLC was developed by using N-(β-aminoethyl)-γ-aminopropyl-methyldimethoxy silane as coupling reagent.
Preparation and characterization of carbosilane dendrimer-bonded silica gel and its use in LC
Divergently synthesized carbosilane dendrimers generations 1(G1) and 2 (G2) with allyl end groups were bonded onto silica gel.
Chemically bonded silica gel was characterized by transmission electron microscopy (TEM), infrared (IR), and other methods.
Fourier transform infrared spectroscopy (FTIR) results show that the special coupling agent POE-g-MAH, in a chemical reaction with CaCO3, can produce an interfacial layer stronger than simple physical adhesion attained with usual coupling agents.
The results agree with that of adhesion friction equations.
Thermal decomposition of cohesive material in the brake block is simultaneously strengthened, so that constituents shed due to loss of adhesion.
In the 20th week, serum lipid level and NO levels were measured, and the expression of vascular cell adhesion molecule-1 (VCAM-1) and cell adhesiveness in aortic endothelia observed by computer-aided system.
Effects of galectin-3 inhibition on endometrial cell cycle and adhesion
