Objective: The aim of this study was to correlate the apparent diffusion coefficient (ADC) value breast cancer with prognostic factors. Methods: 335 patients invasive ductal carcinoma not otherwise specified (IDC NOS) and in situ (DCIS) who underwent MRI diffusion-weighted imaging were included study. ADC calculated using two b factors (0 1000 s mm–2). Mean ADCs IDC NOS DCIS compared evaluated. Among cases NOS, mean lymph node status, size immunochemical Student's t-test. also correlated...
Gallium antimonide (GaSb) has an extremely high electron mobility and excellent lattice match with various III–V ternary quaternary compounds. In this study, the effect of wet-etching processes on GaSb (001) surface was investigated, a focus H2O2. Dilution H2O addition H2O2 in HF/H2O2/H2O, NH4OH/H2O2/H2O, HCl/H2O2/H2O mixtures produced different effects surface. The etching rate increased dilution ratio small amount mixture NH4OH/H2O2/H2O. decreased oxide thickness contact angle XPS Ga 3d Sb...
The novel sulfonated poly(ether sulfone)s containing mesonaphthobifluorene (MNF) moiety were synthesized and characterized their properties. prepared polymers have highly conjugated aromatic structure due to the MNF group which is an allotrope of carbon one atom thick planar sheets sp2-bonded atoms. Poly(ether bearing tetraphenylethylene on polymer backbone by polycondensation followed intra-cyclization from form Friedel-craft reaction with Lewis acid (FeCl3). sulfonation was performed...
