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

Danmarks Geologiske Undersøgelse II. Række, 1943 Den danske Mineralverden er, som man kan tænke sig, ikke særlig rig; Antallet af forskellige Mineraler er ikke stort (ca. 50), og der er ikke blandt Forekomsterne nogen, der udmærker sig ved store og smukke Krystaller, eller er videre iøjnefaldende paa anden Maade. Alligevel frembyder de dog forskelligt af Interesse, og jeg haaber, at en Sammenstilling

Advanced 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 ...

The Geology as an indispensable tool for optimizing the exploration of dimension Stones [PDF]
, 2012 Like any Geological Resource, the Dimension Stones can only be exploited where they occur. How they occur is a reflection of geological history that presided over its formation.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth
Advanced Functional Materials, EarlyView.Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.
