Mass spectrometry methods for imaging cellular lipids, organelles, and proteins
Lipids and their secondary metabolites function as energy storage molecules, structural components in cellular membranes, and messengers that can alter cellular function. Imaging the distributions of various lipid species within tissues and cells can yield insight into the mechanism by which lipids …

Short-time interdiffusion at polymer interfaces: A probe to study polymer motion
… labeling was reversed, i.e., the two end fractions were deuterated. Since, the total deuteration was equal in both the polymers, initially, the concentration of H and D segments was 0.5 at all depths in the HDH/DHD bilayer. Upon interdiffusion, if the polymer chains reptate, i.e., move ends …

The Self-Sustaining Processes in a Hollow Cathode to Produce a Steady Electron Emission
… our lives (i.e., manufacturing, communications, health care, energy). Performance improvements of the hollow cathode seem to have plateaued, though. The two major characteristics are that the electron emission of the cathode reaches a self-sustaining mode, ion bombardment of the low …

Ion-Currents in Oxyfuel Cutting Flames Exposed to External Bias Voltages
… and the current-voltage (i-v) relationship throughout the preheating process of premixed methane-oxygen (CH4-O2) oxyfuel cutting flame subject to electric bias voltages. As such, the equations describing combustion, electrochemical transport for charged species, and potential are …
