Advanced Science, EarlyView.A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

Advanced Science, EarlyView.A rational etching‐induced reconstruction strategy is demonstrated to fabricate one‐dimensional RuIrTe ternary nanotubes with a unique amorphous‐crystalline heterostructure. This hierarchical architecture synergistically optimizes mass transport and electronic configurations, delivering record‐breaking performance in proton exchange membrane water ...

THE K-T AND TERTIARY-PLEISTOCENE SOUTH AMERICAN MAMMALIAN TURNOVERS: SIMILAR PHENOMENA?
Publicación Electrónica de la Asociación Paleontológica Argentina, 2015 The history of South American mammals has been episodic, apparently "stratified", and the "strata" relatively few in number and, as a rule, sharply and clearly separable. This is a consequence of the physical history of the continent.

Java Man and the Colonial Legacy of Fossil Collections
, 2018 This paper looks at human fossil collections in the Netherlands that were excavated in Dutch colonial Indonesia in 1891-92. The most famous specimen is what came to be called Java Man: the skullcap, molar, and thighbone of a homo erectus. It was found on

Precision Lignocellulosic Biorefinery: Process Regulation From Corn Stover to Products
Advanced Science, EarlyView.This study presents a precision biorefinery framework that transforms corn stover into high‐value bioproducts through whole‐process regulation. Mechanical fractionation separates feedstock into parenchyma‐rich short fibers and vascular‐bundle‐dominant long fibers.
