I want to know the answer to the following question:
When was HiCap announced?
All the background I'm provided with is that "In 2012, ORNL researchers announced the successful development of a new absorbent material dubbed HiCap which performs surface retention of solid or gas molecules, atoms or ions and also effectively removes toxic metals from water, according to results verified by researchers at Pacific Northwest National Laboratory.". Is that enough to answer the question?
Answer: yes
