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

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

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 ...

Pore Size Effects of Mesoporous N‐Doped Carbon Nanospheres as Advanced Support Material on the Activity of Molybdenum Sulfide Catalysts for the Hydrogen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

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 ...

Enhancing anti-corrosion performance of anodic film on aluminum-lithium alloy AA2099-T83 by post-treatment in lithium oxalate solutions near room temperature

open access: yesCorrosion Communications
Anodic film formed on aluminum-lithium alloy AA2099-T83 is post-treated in various lithium oxalate (Li2C2O4) solutions to enhance its corrosion resistance.

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Photo-oxidation of EPDM/layered double hydroxides composites: Influence of layered hydroxides and stabilizers

open access: yeseXPRESS Polymer Letters, 2007
The photo-oxidation of ethylene propylene diene monomer (EPDM)/ layered double hydroxide (LDH) composites as well as EPDM/LDH with stabilizers is studied under accelerated UV irradiation (λ≥290 nm) at 60°C for different time intervals.

MPI‐Guided Photothermal Therapy of Prostate Cancer Using Stem Cell Delivery of Magnetotheranostic Nanoflowers

open access: yesAdvanced Functional Materials, EarlyView.
Tumor‐tropic human mesenchymal stem cells (hMSCs) were used as delivery vehicles for magnetotheranostic gold–iron oxide nanoflowers. Magnetic particle imaging of the iron component demonstrated widespread intratumoral distribution and sustained retention in contrast to injection of naked nanoflowers.
