Correlated Dual‐Gradient Electrodes Enabling Spatially Synchronized Sulfur Redox in High‐Mass‐Loading Li–S Batteries Under High Current Densities

open access: yesAdvanced Materials, EarlyView.
Coupling a dual‐gradient carbonized framework with Fe2O3/Fe‐N‐C catalytic sites enables spatially synchronized sulfur redox across the entire electrode thickness in high‐mass‐loading Li–S batteries. This synergistic structural–catalytic design effectively mitigates concentration, ohmic, and electrochemical polarization, thereby achieving high‐capacity ...

Can International Factor Mobility lessen Wage Inequality in a Dual Economy? [PDF]

open access: yes
We introduce international labor mobility in a three-sector general equilibrium model with rural-urban migration. We demonstrate that under some reasonable conditions an inflow of foreign skilled labor (capital) can reduce skilled-unskilled wage ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Does temporary migration have to be permanent? [PDF]

open access: yes
The choice between temporary and permanent migration is today central to the design of migration policies. The authors draw a distinction between the two types of migration on the basis of the associated social cost and the dynamics of learning by ...
