Spatio-temporal stable isotope variation of a benthic primary consumer in a simple food web in a strongly acidic lake [PDF]

PeerJ, 2019
Analysis of aquatic food webs is typically undertaken using carbon and nitrogen stable isotope composition of consumer and producer species. However, the trophic consequences of spatio-temporal variation in the isotope composition of consumers have not ...

Boosting Seawater Desalination by Ampere‐Level Nitrate Electroreduction On Defect‐Rich Ultrathin RuCu Alloy Nanostructures

Advanced Materials, EarlyView.
Defect engineering of ultrathin RuCu alloy nanostructures has been successfully achieved to enhance ammonia electrosynthesis under indutrial‐level current density. Simultaneously, the stable ampere‐level operation of nitrate electroreduction on defective RuCu nanostructures can drive seawater desalination at an ultrafast salt removal rate, offering an ...

A divergent heritage for complex organics in Isheyevo lithic clasts [PDF]

, 2017
Primitive meteorites are samples of asteroidal bodies that contain a high proportion of chemically complex organic matter (COM) including prebiotic molecules such as amino acids, which are thought to have been delivered to Earth via impacts during the ...

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

Advanced Materials Technologies, EarlyView.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...
