Effect of calcium aluminate cement variety on the hydration of Portland cement in blended system [PDF]
Two kinds of CACs with different monocalcium aluminate (CA) contents were used in the PC/CAC (PAC) mixtures. Effects of CA and CACs on the properties of PAC were analyzed by setting times and the compressive strength tests, and also by means of ...

Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

The social origins of cooking and dining in early villages of western Asia [PDF]
This paper explores social customs of cooking and dining as farming emerged in the earliest villages of Palestine and Jordan (12,650–6850 cal BC). The approach is a spatial analysis of in situ hearths, pits, bins, benches, platforms, activity areas ...

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,

Experimental evaluation of sustainable geopolymer mortars developed from loam natural soil
Natural soil can play an important role in the production of geopolymer due to having required aluminosilicate precursors and abundant availability. Numerous aluminosilicate materials have been used in the past for the production of geopolymers but they ...

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