Message from the CEO, CTO (Prof. Yoshikawa)

As you know, a smart phone has got a variety of different capabilities to provide you with not only e-mail, game, net surfing, chatting, SMS, but also digital camera, music, car navigation and even book as well. It took only 3 years to realize this amazing paradigm shift. If you compare the shift from record to CD, DVD, the speed is completely different.
So far, in the crystalline materials community, there are two long-accepted theories.
1. It takes at least 10 years for new excellent crystalline material that you have found to be loaded in the device.
2. If you are lucky, you can find 3 excellent new crystalline materials after your 1000 times failure.
However, if you can shorten the development time from 10 years to 3 years, what will happen to you?
If you can find 3 excellent new crystalline materials before you try 100 composition, what will happen to you?
Remarkable paradigm shift will occur in your field. We do hope to help your organization to work smarter and grow faster based on your brilliant ideas.

Message from the Technical Director (Dr. Kochurikhin)

Within the last few decades a lot of laboratories and researchers in the world have decided that it was more optimal regarding time and money saving to investigate crystal growth processes by the computer simulation instead of growing real bulk crystals.
Our philosophy is the opposite one: we have found it challenging, and due to this concept C&A team has got great experience, developed dozens of techniques, finally resulting in a proven track records of successful crystal growth, and we enjoy doings this. So, this unique combination might be a real leverage for our customers, as well as C&A capability to supply them with different crystals in accordance with particular requirements.
You are kindly requested to express your technology ambitions to us and our team skills and devotion will be a catalyst for your business related to the single crystals.
