Carbon storage and DNA absorption in allophanic soils and paleosols [PDF]

open access: yes, 2014
Andisols and andic paleosols dominated by the nanocrystalline mineral allophane sequester large amounts of carbon (C), attributable mainly to its chemical bonding with charged hydroxyl groups on the surface of allophane together with its physical ...

Hyperelastic Starch Hydrogel Configures Edible and Biodegradable All‐Components for Soft Robots

open access: yesAdvanced Science, EarlyView.
Hyperelastic starch hydrogel is tailored via a phase separation strategy of solvent‐antisolvent co‐modulation. The mechanical performance of starch hydrogel is widely tuned with maximum strains: 194.4–361.4%; maximum tensile stresses: 34–192 kPa; and Young's moduli: 36.0–205.8 kPa. Notably, the hydrogel achieves complete soil degradation within 24 days

Remote Modulation of Single‐Atom Catalyst Boosts High‐Valent Cobalt–Oxo Species Generation for Water Purification and Detoxification

open access: yesAdvanced Science, EarlyView.
This study develops a phosphorus‐doped cobalt single‐atom catalyst that enhances high‐valent cobalt–oxo species generation for water purification. This atomic‐level tuning boosts the catalyst's activity by 3.5 times, enabling efficient pollutant degradation. A continuous‐flow reactor achieves high, long‐term removal efficiency, producing water with low

Proximity Engineering of Fe‒N4 Twins for Oriented Generation of Singlet Oxygen for Hospital Wastewater Treatment

open access: yesAngewandte Chemie, EarlyView.
Precise modulation of Fe–N4 site distances constructs spin‐regulated Fe–N4 twins, triggering a volcano‐type Fenton‐like activity and promoting oriented singlet oxygen generation. The twin‐site catalyst enables highly selective and efficient hospital wastewater purification with simultaneous pharmaceutical degradation and disinfection under low ...

Fast Thermoelectric Responses from Unconventional Na‐I Stoichiometry in Reduced Graphene Oxide Films

open access: yesAdvanced Science, EarlyView.
By coating the graphene oxide suspension and the dilute NaI solution layer‐by‐layer from bottom up, this work achieves a heterogeneous structure from asymmetry of the up and bottom surface Na and I atomic ratios in reduced graphene oxide (rGO) films, which exhibits fast thermoelectric responses.
