Some observations on the calcium aluminate carbonate hydrates

open access: yes, 1960
Two calcium aluminate carbonate hydrates, previously reported in the literature, were prepared and various properties determined. The compound 3CaOAl2O3CaCO311H2O, was prepared by precipitation from mixtures of solutions of calcium aluminate, calcium ...

Effect of Annealing on Calcium Carbonate Morphology of Mollusk Shell

open access: yes, 2011
After the aragonite nacreous layer and cross section of Periglypta Magnifica mollusk shell were annealed, the influences, including crystallization temperatures, crystallization time and concentrations of calcium chloride aqueous solution on the crystal ...

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

open access: yesAdvanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
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 ...

Comparison between microbiologically-induced calcium carbonate precipitation and magnesium carbonate precipitation

open access: yesYantu gongcheng xuebao, 2018
The magnesium carbonate has a cementing feature like calcium carbonate, and the strength of magnetite ore is much higher than that of calcium ore, so it is important to study the solidification technology of magnesium carbonate. The absorbance and urease

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

1-dimensional modelling and simulation of the calcium looping process [PDF]

open access: yes, 2012
Calcium looping is an emerging technology for post-combustion carbon dioxide capture and storage in development. In this study, a 1-dimensional dynamical model for the calcium looping process was developed. The model was tested against a laboratory scale
