Anion‐Exchange‐Enabled Hydrogel Electrolytes With High Zn2+ Transference for Dendrite‐Free Flexible Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A high‐Zn2+‐transference hydrogel electrolyte of ex‐PDADAM is developed via anion exchange at quaternary ammonium sites, achieving high Zn2+ transference number (0.86), ionic conductivity (8.10 mS cm−1), and toughness (51.25 MJ m−3). Symmetric cells are operated stably for over 2000 h, while flexible pouch cells retain 90.9% capacity after 300 cycles ...

Facile synthesis of Ca/Mg/Al/Fe layered double hydroxides using steelmaking slag as raw material

open access: yes, 2016
Ca/Mg/Al/Fe layered double hydroxides (LDHs) were synthesized through coprecipitation using steelmaking slag as raw material. The structural morphology of Ca/Mg/Al/Fe LDHs was characterized, and results revealed a well-defined shape with obvious ...

Surprising Water Slipping Performance on Highly Hydrophilic PEG‐Derived Monolayer‐Covered Surfaces: Preparation, Mechanism, and Application

open access: yesAdvanced Functional Materials, EarlyView.
Highly hydrophilic surfaces (water contact angle, ≈17.7°) exhibiting surprising water slipping performance (sliding angle, ≈7.3°) are successfully prepared via simple chemisorption of polyethylene glycol (PEG) organosilane and subsequent alkali‐treatment.

Native metals, selenides, halogenides and brown ore assotiated minerals from the Amur and Verkhnyaya Arsha deposits (Southern Urals)

open access: yesЛитосфера, 2015
The ores of Amur (Zn) and Verkhnyaya Arsha (Pb-Zn) stratiform sulfide deposits are replaced by brown ores in a supergene conditions. The main types of brown ores are massive aggregates of iron hydroxides, quartz breccias cemented by iron hydroxides and ...

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

The mineralogy and chemistry of fine-grained sediments, Morphou Bay, Cyprus [PDF]

open access: yesHydrology and Earth System Sciences, 2002
The mineralogy and chemistry of the less than 20μm fraction of marine sediments at Morphou Bay, north-west Cyprus, are presented to characterise fine-grained sediment supplies from basic and ultrabasic rocks of the Troodos Massif within a typological ...

Layer Structured Manganese Oxide Hydroxides

open access: yesCHIMIA, 1980
Crystallinity and morphology of synthetic 10 Å-manganate (buserite) depend a) on the presence or absence of amorphous colloidal silica and co-precipitating amorphous ferric hydroxide, and b) on the ageing under pressure or normal conditions. Experiments

Thermodynamics of Volatile Silicon Hydroxides Studied

open access: yes, 2001
Silicon-based ceramics are promising candidate structural materials for heat engines. The long-term stability of these materials to environmental degradation is dependent on the formation and retention of a protective SiO2 layer.

Exfoliation of layered double hydroxides for enhanced oxygen evolution catalysis [PDF]

open access: yes
The oxygen evolution reaction is a key reaction in water splitting. The common approach in the development of oxygen evolution catalysts is to search for catalytic materials with new and optimized chemical compositions and structures.
