Facile route to freestanding CH3NH3PbI3 crystals using inverse solubility

Michael Graetzel, Ulf Anders Hagfeldt, Kazuteru Nonomura, Jeannette Medina Kadro

CH3NH3PbI3 was found to exhibit inverse solubility at high temperatures in gamma-butyrolactone. Making use of this unusual, so far unreported phenomenon, we present a facile method for the growth of freestanding crystals of CH3NH3PbI3 from solution without ...

Degradation mechanism of slag blended mortars immersed in sodium sulfate solution

Karen Scrivener, Wei Sun, Cheng Yu

Additions of slag are usually considered to give cementitious materials which perform well in sulfate bearing environments. This paper compares the deterioration of slag cement blends to those of plain Portland cement and demonstrates that this occurs more ...

Parametric Polytope Reconstruction, an Application to Crystal Shape Estimation

Colin Neil Jones, Jean-Hubert Hours

In situ imaging techniques are a promising direction for monitoring the distribution of crystal sizes and shapes during a crystallization process. Nevertheless, no tractable method yet exists for estimating complex crystal shapes. In this paper, an in situ ...

Expansion mechanisms in calcium aluminate and sulfoaluminate systems with calcium sulfate

Karen Scrivener, Christophe Gosselin, Julien Bizzozero

The long-term expansion of calcium aluminate cement and calcium sulfoaluminate cement in the presence of added gypsum has been studied for samples cured under water. Progressively higher amounts of gypsum were added to the CAC or CSA and it was found that ...

Mechanism of expansion of mortars immersed in sodium sulfate solutions

Karen Scrivener, Wei Sun, Cheng Yu

The mechanisms behind the expansion of samples immersed in solutions containing sulfate ions have been controversial. Expansion is believed to originate in the formation of ettringite, but it is not possible to find any direct correlation between these two ...

Advanced divertor configurations with large flux expansion

Basil Duval, Stefano Coda, Holger Reimerdes, Benoît Labit, Mario Ludovico Podesta, Wouter Vijvers

Experimental studies of the novel snowflake divertor concept (D. Ryutov, Phys. Plasmas 14 (2007) 064502) performed in the NSTX and TCV tokamaks are reviewed in this paper. The snowflake divertor enables power sharing between divertor strike points, as well ...

On the relevance of volume increase for the length changes of mortar bars in sulfate solutions

Karen Scrivener, Barbara Lothenbach, Wolfgang Kunther

The ingress of sulfate ions into cementitious materials leads to the formation of ettringite, gypsum and other phases. The increase in solid volume through the formation of these phases is often assumed to be the only reason for expansion. In this paper we ...
