Subject: [off topic] Control of crystals' direction and position in the drop. From: Nian Huang huangnian {- at -} GMAIL {- dot -} COM Date: 2011-11-14
Dear All, Does anybody find a way to control a crystal's positioning in the drop? I have needle shaped crystals. What I found out is that the vertical positioned crystals always grow much thicker than the crystals laying flatly. But unfortunately, it is a completely random event and only 1% crystals can appear vertically. I have tried different formats of plates and equilibration techniques w/o much success. Any suggestion is highly appreciated.
