Improving Effect of Graphene on Electrochemical Properties of Fe2O3 Anode Materials

open access: yesMetals, 2022
Transition metal oxides have a high initial charge-discharge capacity of 800–1000 mAh/g, the electrochemical performance, cyclic performance and rate performance of the composite of transition metal oxide and graphene have been improved due to the unique

Cyclic cohomology after the excision theorem of Cuntz and Quillen [PDF]

open access: yes, 2013
The excision theorem of Cuntz and Quillen established the existence of a six term exact sequence in the bivariant periodic cyclic cohomology HP*(–,–) associated with an arbitrary algebra extension 0 ? S ? P ? Q ? 0.

Cyclic AMP signalling in pancreatic islets [PDF]

open access: yes, 2010
Cyclic 3'5'AMP (cAMP) is an important physiological amplifier of glucose-induced insulin secretion by the pancreatic islet β-cell, where it is formed by the activity of adenylyl cyclases, which are stimulated by glucose, through elevation in ...

Assessment of Web Panel Zone in Built-up Box Columns Subjected to Bidirectional Cyclic Loads

open access: yesBuildings, 2022
The behavior of the web panel zone has a direct effect on the cyclic performance of steel moment connections. While the mechanisms of web panel zone failure are known under cyclic load, little is known about the behavior of the web panel zone under ...
