The age separating early deaths from late deaths [PDF]
There is a unique threshold age separating early deaths from late deaths such that averting an early death decreases life disparity, but averting a late death increases inequality in lifespans.life disparity ...

The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.

With a charge‐ion coupling engineering strategy, a K+/vacancy disordered K0.5Mn0.8Co0.1Ti0.1O2 material has been designed. The targeted transition metal doping disrupts charge ordering and inducing K+/vacancy disordering, thereby enabling rapid K+ diffusion through interconnected channels and a stable solid‐solution reaction mechanism.

Appreciation of the renminbi and urban-rural income disparity [PDF]
Although poverty has been significantly decreased in China over the last twenty years, this decrease has been highly unequal across the provinces and has brought increased disparity in urban and rural per capita income.

Tough Injectable Hydrogels Enabled by Integrating Rigid Homogeneous Framework With Flexible Chains
Tough injectable hydrogels are constructed by integrating a rigid, homogeneous hyaluronic acid framework with flexible long‐chain connectors. This framework–flexible structure simultaneously enhances network uniformity and promotes effective energy dissipation by enlarging plastic deformation zones under compression.

A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
