Hyperbranched Interpenetrating Hydrogen Bond Network (HIHBN) Proton Exchange Membrane for Fuel Cells Above 220 °C

open access: yesAdvanced Functional Materials, EarlyView.
A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.

Please Avoid Plotting Analytical Response against Logarithm of Concentration.

Analytical Chemistry, 2020
This perspective highlights a malpractice in handling calibration datasets. It refers to relating analytical response with logarithm of concentration, fitting such a dataset with linear function, and deriving method characteristics from the slope of that

Logarithmic strain, logarithmic spin and logarithmic rate

Acta Mechanica, 1997
Two yet undiscovered relations between the Eulerian logarithmic strain inV and two fundamental mechanical quantities, the stretching and the Cauchy stress, are disclosed. A new spin tensor and a new objective tensor-rate are accordingly introduced. Further, new rate-form constitutive models based on this objective tensor-rate are established.
