Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

open access: yesAdvanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Engineering Pendant Group Chemistry to Control Hydrophilicity and Oxidative Degradation of Thioketal‐Based Biomaterials

open access: yesAdvanced Functional Materials, EarlyView.
Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.

FBG-based fibre-optic current sensors for power systems protection : laboratory evaluation

open access: yes, 2009
Conventional differential current unit protection schemes rely on a pair of electronic protection relays that measure current phasors separately at the boundaries of the protected zone.

Invisible Polymer Walls Enhance Reorientational Optical Nonlinearity in Oligothiophene‐Doped Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
The polymer wall stabilized dye‐doped liquid crystals (PWLCs) enhance the sensitivity of photoinduced molecular reorientation in dye‐doped LC systems. The PWLC with an invisible polymer wall successfully reduces the threshold intensity and functions as an optical limiter under the incidence of low intensity light laser source.

Signal Extraction from Inrush Current for Inter-Winding Fault Protection of Power Transformers

open access: yes
In case of transformer failure there is a high risk of losing part of power system, which can result in disruption for consumer power supply. This is the main reason for power transformer protection requirements to be so high.
