Al3+/Ta5+ Co‐Doping Promotes Homogeneous Li+ Transport Enabling High Performance Ni‐Rich Layered Oxide Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
Al3+/Ta5+ co‐doping refines the primary particles of LiNiO2, reduces Li/Ni antisite disorder, and expands the c‐axis lattice parameter, thereby enabling faster and more homogeneous Li+ transport. Such rapid and homogeneous Li+ transport suppresses high‐voltage phase transitions and microcrack formation, ultimately improving the rate capability and long‐

Efficient Time-Domain Image Formation with Precise Topography Accommodation for General Bistatic SAR Configurations [PDF]

open access: yes, 2011
Due to the lack of an appropriate symmetry in the acquisition geometry, generalised bistatic SAR cannot benefit from the two main properties of low-to-moderate resolution monostatic SAR: azimuth-invariance and topography-insensitivity.

Wastewater surveillance of SARS-CoV-2 variants to track community outbreaks in Hong Kong

open access: yesThe Microbe
Sewage surveillance of SARS-CoV-2 serves as an effective tool to monitor the progression of the pandemic. Although standard qPCR confirms the presence of SARS-CoV-2 in sewage, the variant identity of SARS-CoV-2 is not addressed.

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

open access: yesAdvanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...
