Perovskite solar cells with iridescent colors
With the maturing of the perovskite solar cells technology, it is highly desirable to develop colorful solar cells to satisfy the requirements of aesthetic purposes in applications including building integrated photovoltaics and wearable electronics.
Fluoride radically improves the stability of perovskite solar cells
Researchers have discovered that adding a small amount of fluoride to perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly.
Origami, 3D printing merge to make complex structures in one shot
By merging origami with 21st century technology, researchers have created a one-step approach to fabricating complex origami structures whose light weight, expandability, and strength could have applications in everything from biomedical devices to equipment used in space exploration.
Nanotube rebar makes graphene twice as tough
Rebar graphene is the nanoscale analog of rebar (reinforcement bars) in concrete, in which embedded steel bars enhance the material's strength and durability. Rebar graphene, developed by the Rice lab of chemist James Tour in 2014, uses carbon nanotubes for reinforcement.
Large single-crystal graphene is possible!
Boasting the conductivity, strength and flexibility we wished for, graphene was proposed as one of the most likely substitutes for silicon and other materials. Its launch into the market however is still slow. What is curbing graphene from industrial applications?
New lithium-oxygen battery greatly improves energy efficiency
Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their weight.
Beijing Tiertime Technology Co Ltd
Tiertime was formerly known as Beijing Yinhua Laser Rapid Prototyping and Mould Technology Co., Ltd., a company created by a Tsinghua Professor Yan Yongnian, who is recognized as the first person to explore 3D printing in China. Tiertime is currently the single largest manufacturer of 3D printers in China,
Flexible solar cell woven into fabric
Wearable electronics are quickly becoming the fashion. And there could soon be a way to power those electronics indefinitely, now that scientists in China have developed a solar cell 'textile' that could be woven into clothes.
The murky waters of energy harvesting
The confluence of sea water and fresh water with its inherent difference in salinity is providing researchers with a new approach to energy harvesting.
