Atomic and nano-scale characterization of a 50-year-old hydrated C3S paste [PDF]

open access: yes, 2015
This paper investigates the atomic and nano-scale structures of a 50-year-old hydrated alite paste. Imaged by TEM, the outer product C-S-H fibers are composed of particles that are 1.5-2 nm thick and several tens of nanometers long.

Recent insights into xerogel and aerogel mineral composites for CO 2 mineral sequestration [PDF]

open access: yes, 2011
Supercritically dried composites have already been analysed and proposed as carbon dioxide sequesters. However, the economical and energetic costs of the supercritical drying process had to be re-evaluated, and were eventually found not to enhance the ...

A practical method for preparing Ca(OH)2 nanodispersions for the consolidation of archaeological calcareous stones [PDF]

open access: yes, 2018
Exposure to atmospheric conditions results in considerable deterioration of calcareous building stones, lime mortars and plasters in archaeological monuments, requiring several conservation treatments.

Comparison of Two Processes Forming CaCO3 Precipitates by Electrolysis

open access: yesEnergies, 2016
As one of the carbon capture and utilization (CCU) technologies, mineral carbonation which has been introduced to reduce the carbon dioxide (CO2) concentration in the atmosphere is a technology that makes it possible to capture CO2 and recycle byproducts

Ex-situ mineral carbonation: resources, process and environmental assessment (Carmex project) [PDF]

open access: yes, 2013
This article presents the main results of the Carmex project (2009-2012), whose purpose was to review the feasibility of ex-situ mineral carbonation in terms of resource availability, performance of the aqueous mineral carbonation process and life cycle ...

Structure of supercritically dried calcium silicate hydrates (C-S-H) and structural changes induced by weathering [PDF]

open access: yes, 2013
The nanostructure of supercritically dried calcium silicate hydrates was researched. This particular drying procedure was used to avoid nanostructure modifications due to conventional drying processes.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Results of an aqueous source term model for a radiological risk assessment of the Drigg LLW Site, U.K. [PDF]

open access: yes, 2011
A radionuclide source term model has been developed which simulates the biogeochemical evolution of the Drigg low level waste (LLW) disposal site.

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

open access: yesAdvanced Engineering Materials, EarlyView.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.
