Lediko, jako pierwsza firma z branży oświetleniowej, została uhonorowana certyfikatem Zielona Marka w zakresie wprowadzania energooszczędnych i ekologicznych technologii LED w oświetleniu.
Supercapacitors promise recharging of phones and other devices in seconds and minutes as opposed to hours for batteries. But current technologies are not usually flexible, have insufficient capacities, and for many their performance quickly degrades with charging cycles. Researchers at QMUL and the University of Cambridge have found a way to improve all three problems in one stroke. Their prototyped polymer electrode, which resembles a candy cane usually hung on a Christmas tree, achieves energy storage close to the theoretical limit, but also demonstrates flexibility and resilience to charge/discharge cycling.
