Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Ion beam limits [PDF]

open access: yes, 1975
The cooperative physical processes of ion source and ion beam physics in magnetic fields can be separated into plasma internal motions, motion from the source plasma into the beam, and beam formation. A few experiments demonstrate that these processes are consistent with elementary laws of charge diffusion.
