Colloid‐Mediated Synthesis of Hierarchically Porous Amorphous Catalyst for Durable Industrial‐Scale Water Electrolysis

open access: yesAdvanced Materials, EarlyView.
A colloid‐mediated electroless plating (CMEP) strategy is proposed to fabricate hierarchically porous, amorphous Fe‐doped NiWB electrocatalysts under ambient conditions. The in situ formation of Fe‐W‐O colloidal species guides the formation of robust, porous catalyst layers with excellent mass transfer and durability, sustaining 500 mA cm−2 for 2000 h,

On Camera-Trapping Terrestrial Squamates

open access: yes, 2016
In all fields of wildlife research and management, fundamental biodiversity and species distributional data are required. Yet, the difficulty that wildlife researchers face detecting small and cryptic species, in particular snakes and lizards (squamates), has led to gaps in fundamental knowledge.

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

open access: yesAdvanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Observation of the Kibble-Zurek scaling law for defect formation in ion crystals

open access: yes, 2013
Traversal of a symmetry-breaking phase transition at a finite rate can lead to causallyseparated regions with incompatible symmetries and the formation of defects at their boundaries.
