In a ceremony that did not miss the welcome mat in Unesco headquarters in Paris , scientific China Vivian Wing-Wah Yam is sincere in ensuring that their dedication to anything not considered a job. "It's my hobby, a part of me," he said before receiving the award L'Oréal Unesco For Women in Science , lobby on several occasions of Nobel Prizes .

with four other women, Faiza Al-Kharafi, of Kuwait; Silvia Torres-Peimbert , Mexico; Jillian Banfield, the U.S., and Anne L'Huillier , Switzerland, the china was honored for scientific research in materials, especially for his contribution in a more efficient solar energy. Unlike his fellow Liu Xiaobo, Nobel Peace , this expert in chemistry itself was unable to attend his prize. Interview
This year marks the International Year of Chemistry in the world and the centenary of Marie Curie Nobel. As a woman scientist, has been easy to develop his career in Hong Kong?
For nothing. There are many women who have careers in Hong Kong and have reached high positions. Also, I had the support of my husband, also a chemist and know that I love my profession, and with the help of my mother to raise my two daughters, 11 and 14. What is important is not the hours you spend with your family, but
as you give them. I take on Sunday, I do not work, to be with them. When did you decide to be chemistry?
Since I was little, watching the colors and I wondered why there would be red, blue, how would the molecules of each of them. I always thought that the chemicals were artists who could create. Even as a little girl and I liked to discuss and reach objective goals. I characterized my thinking and I like science because it is predictable.
discuss their research. Currently, each cell picks up a low level of solar energy, which is inefficient and expensive ... How can you top that?
Our research is based on analysis of inorganic and organic cells. Photoactive materials can absorb and emit light. With them you can get solar efficiency. Currently, 90% of the energy is lost. However, it was discovered that the cells more efficient in recruiting solar energy from the silicon crystals, which are very expensive to produce but are able to convert about 30% solar energy. Organic materials are cheaper and can be used for printing, but have advantages and disadvantages.
as?
Well, people always complain about organic uses. If you go to the Louvre Museum and want to take a photo, you can not do with flash because it deteriorates the paint. Hence we need to study more to find materials more resistant and able to be more exposed to the sun.
China Are you spending a lot of investment in researching new energy? Can be an alternative to oil?
Yes, of course. China is one of the largest consumers of the world and therefore the government is seeking alternative energy. Solar energy is only one of them. Do not think it will solve all the problems of supply, but is an alternative.
Do you think the potential of Spain's sun should invest more in R & D to make this energy efficient?
Recently I was in Zaragoza. The Government is doing very well. In the last 10 years is a lot of money investing in research of this type of knowledge and providing facilities for researchers.
However, the crisis has reduced resources.
occurs worldwide. Governments over the short term look at the long term. They want the application research in a short amount of time to invest in them, and that in science, is difficult.
How can institutions encourage young people to research?
is true, young people do not see many attractions. It's a trend around the world, but is not employed by the government but rather the teachers and the university. In Hong Kong are making programs to engage students, even when very young, from primary school, developing the week of chemistry, physics, with amusing examples, they can check. scientific career since has been to encourage childhood.
Can it be this year a chance to bring chemistry?
Sure. The whole world celebrates the achievements of chemistry. And, frankly, I've said many times, chemicals are the good guys in reference to that there are voices critical of some chemical research by less than noble purposes. It is a year where we can target them and intensify the promotion of chemistry
