Abstract Pre-soaked flax stems were subjected to microwave assisted retting at different power levels and the effectiveness of microwave assisted retting was studied through the analysis of chemical compounds presented in the retted flax fibers processed from the stems. Response surface statistical design was used for this study with JMP® 10 software.

Abstract The structural properties and the Cd-distribution of CdSe layers with a nominal thickness between 0.5 and 3.6 monolayers (ML) in a ZnSe matrix were investigated by plan-view and cross-section transmission electron microscopy. All layers contain a high density of Cd-rich islands with sizes below 10 nm, which are completely embedded in a 3 nm ...

A methodology for equation-based analysis of large chemical processes using the functional matrix
Korean Journal of Chemical Engineering, 1987The equation-based approach to process analysis is necessary for efficient optimization of large and complex processes, and involves the problem of solving a large number of equations. To complement this approach, an improved equation-solving system using the functional matrix suggested by Mattione, Meir and Book was developed, and its capacity for the

Chemical state analysis of ZnO/Ag film interface utilizing the matrix effect
Applied Surface Science, 2003Abstract The degree of oxidization of Ag in the interface of ZnO/Ag has been investigated by utilizing the matrix effect. We monitored various secondary ions (Ag+, CsAg+, Ag−, AgO−) under Cs+ bombardment during the depth profile analysis. It was found that Ag+, Ag−, AgO− secondary ions exhibited a characteristic enhancement of secondary ion yield due

Matrix metalloproteinases (MMPs) play a critical role in physiological processes and pathological conditions such tumor invasion and metastasis. In recent years, a number of MMP inhibitors have been proposed, including the chemically modified tetracyclines (CMTs), which have been evaluated in preclinical cancer models showing promising results.

Abstract The atomic absorption spectrometric determinations of iron, calcium, and magnesium in the fluoboric-boric acids matrix are seriously interfered by the presence of silicon and aluminum. These interferences can be overcome by preparing the standard solutions of magnesium, calcium, and iron with silicon and aluminum concentrations matching ...
