Crystallography in the Americas

|  North America  |  Canada  |

The American Crystallographic Association represents both Canada and the United States of America to the International Union of Crystallography (IUCr).There is a Canadian division of the ACA and a Canadian representative on the ACA Council. In 2014 the Latin American Crystallographic Association (LACA) became a Regional Associate of the IUCr. Several Latin American countries have a national crystallographic organization including Mexico and Brazil Here we focus on advances in structural science in the US and Canada, as well as highlighting scientific outreach activities of prominent US/Canadian researchers to Latin America.
