Perovskite Stability Gets a 2D Solution
Perovskite structures suffer from moisture and thermal stability issues which prevent their commercial use. This promising solution using organic cations leads to a record high PCE for 2D perovskite devices.
Thermal Camouflage: Illusion Meta-Devices
Camouflage, illusion or cloaking devices, once deeply rooted in science-fiction, can make an object appear “invisible”. A novel technique for thermal illusion meta-devices is reported.
Cloak of Inv sib ity
A true invisibility cloak would encompass an object, and manipulate light, in a manner such that it traveled around the object, rather than reflecting off it. A recent paper reports some exciting progress toward such a design.
Enhancing Catalyst Stability for Polypropylene Production
The important role of surface-bound hydroxy groups of vanadium catalysts under reaction conditions by employing in situ DRIFTS experiments and DFT calculations is elucidated.
Carbon Nanotube Surfaces as Ultrafast Emitters
Carbon nanotube surfaces as ultrafast electron sources could influence the next generation of attosecond science and light-wave electronics research.
Smart Windows Use Plasmons to Adapt to Sunlight Alone
Smart windows switch between transparent and opaque states based on environmental cues. Researchers reveal a prototype that exploits plasmons, converting incident sunlight into local thermal energy to trigger the switch.
