50 DESIGN007 MAGAZINE I MAY 2018 down into the report the numbers get even more interesting; the median tenure for work- ers between the ages of 25 and 34 years is just under three years, while for workers ages 55 to 64 years is a little longer than 10 years. To put it simply, if you want to hire someone young to grow with your company, it is more than likely that they will leave within a few years to continue to grow their own career and seek new challenges and opportunities. It may be tempting to avoid hiring someone who is older because you're worried that you won't get as much time with them, but again the sta- tistics indicate otherwise. Older workers are often happier to settle down and commit to their places of employ- ment. You will get an employee who statistics say will stay with you three or four times as long, plus you will get the advantages of all their years of experience as well. In the end, no one knows better than you who you should be hiring for your company. You need to carefully analyze your needs and look for people that will meet those needs. My purpose here is simply to say that if you narrow your search focus too tightly, you may miss out on some great applicants. Don't be afraid to buck industry traditions and standards when you search for new hires. As Charles Howard learned with Seabiscuit, you may find someone who doesn't meet your company's traditional criteria, but who is exactly the right person for the job. DESIGN007 Tim Haag is a consultant based in Portland, Oregon. Rice materials scientist Pulickel Ajayan and colleagues extracted 3-atom-thick hematene from common iron ore. Hematene may be an efficient photocatalyst, especially for splitting water into hydrogen and oxygen, and could also serve as an ultrathin magnetic material for spin- tronic-based devices, the researchers said. "2D magnetism is becoming a very exciting field with recent advances in synthesizing such materials, but the synthesis techniques are complex and the materi - als' stability is limited," Ajayan said. "Here, we have a simple, scalable method, and the hematene structure should be environmentally stable." Ajayan's lab worked with researchers at the Univer- sity of Houston and in India, Brazil, Germany and else- where to exfoliate the material from naturally occurring hematite. The researchers also discovered that hema- tene's magnetic properties differ from those of hema- tite. While native hematite is antiferromagnetic, tests sho wed that hematene is ferromagnetic, like a common magnet. In ferromagnets, atoms' magnetic moments point in the same direction. Unlike carbon and its 2D form, graphene, hematite is a non-van der Waals material, meaning it's held together by 3D bonding networks rather than non-chemical and comparatively weaker atomic van der Waals interactions. "Most 2D materials to date have been derived from bulk counterparts that are layered in nature and generally known as van der Waals solids," said co-author Professor Anantharaman Malie Madom Ramaswamy Iyer of the Cochin Univer- sity of Science and Technology, India. "2D mate- rials from bulk precursors having (non-van der Waals) 3D bonding networks are rare, and in this context hematene assumes great significance." Hematene Joins Parade of New 2D Materials
