Light‑Driven Propulsion of Graphene Aerogels in Microgravity

Advanced Science, EarlyView.
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Alkyne‐Based Dual‐Function Self‐Assembled Monolayers for Efficient and Stable p‐i‐n Perovskite Solar Cells

Angewandte Chemie, EarlyView.
A novel molecular design strategy is employed to modify the D–A type SAM using an alkyne linker. Incorporation of the alkyne linker enhanced π‐electron delocalization, facilitating more efficient hole transfer, and strengthened interfacial bonding, thereby improving device stability. As a result, the perovskite solar cells achieved an impressive PCE of

Tissue-type plasminogen activator-primed human iPSC-derived neural progenitor cells promote motor recovery after severe spinal cord injury. [PDF]

, 2019
The goal of stem cell therapy for spinal cord injury (SCI) is to restore motor function without exacerbating pain. Induced pluripotent stem cells (iPSC) may be administered by autologous transplantation, avoiding immunologic challenges.

Enhanced Two-Photon Absorption in a Hollow-Core Photonic Bandgap Fiber

, 2010
We show that two-photon absorption (TPA) in Rubidium atoms can be greatly enhanced by the use of a hollow-core photonic bandgap fiber. We investigate off-resonant, degenerate Doppler-free TPA on the 5S1/2 - 5D5/2 transition and observe 1% absorption of a

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, EarlyView.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...
