Electromechanical Fredericks effects in nematic gels.
The solid nematic equivalent of the Fredericks transition is found to depend on a critical field rather than a critical voltage as in the classical case. This arises because director anchoring is principally to the solid rubbery matrix of the nematic gel rather than to the sample surfaces. Moreover, above the threshold field, we find a competition between quartic (soft) and conventional harmoni...
متن کاملCrossed immunoelectrophoresis from sodium dodecyl sulfate- polyacrylamide gels after fixation and staining and without nonionic detergent intermediate layers.
A modified method is described for crossed immunoelectrophoresis in which the first-dimension separation has been carried out by sodium dodecyl sulfateepolyacrylamide gel electrophoresis. The described method does not require nonionic detergents and is carried out after fixation and staining of the polyacrylamide gel. This permits more precise alignment of immunoprccipitatcs with polypeptide ba...
متن کاملToxicity of nonionic surfactants
Nonionic surfactants are amphilic chemicals that enhance desorption and bioavailability by increasing solubility and dispersion of poorly soluble hydrocarbons and oils. This study was conducted to determine the toxicity of commercial nonionic surfactants by using the Microtox Acute Toxicity test which is a rapid, simple test for toxicity. The test uses the luminescent bacterium V. fischeri as t...
متن کاملElectromechanical Catastrophe
A transducer is a system that couples two loads. For example, an electromechanical transducer couples a mechanical force and an electrical voltage. A two-load, nonlinear system can exhibit rich behavior of bifurcation, which can be displayed in a three-dimensional space, with the horizontal plane representing the two loads, and the vertical axis representing the state of the system. In this thr...
متن کاملTime to abandon nonionic contrast.
E very year, over 1 0 million Intravascular contrast examinations are performed In the United States. A typical dose of 200 mL of high-osmolality Ionic radiographic contrast costs approximately $8 (e.g. , diatrizoate, iothalmate, and others). In comparIson , low-osmolality nonionic contrast costs up to $ 1 70 for equivalent volumes (e.g. , iopamldol. iohexol. and others). If nonlonic contrast w...
