Eight papers entered the Top 10 this week, with Gui Bazan and Thuc-Quyen Nguyen’s communication describing a new small molecule for high-efficiency solar cells, p-DTS(FBTTh2)2 back in the number one spot.
Coming in at number 4 is “Super-Stretchable Spring-Like Carbon Nanotube Ropes” by Yibin Li, Anyuan Cao, and colleagues, with their cover also in the top 10 at number 9. These ropes are made by twist-spinning single-walled nanotube films to form closely arranged loops with long-distance order. The nanotube ropes have spring constants comparable to conventional steel and can sustain very large tensile strains (up to 285%) without structural failure by loop separation and straightening.
