The Deepest Blue: Major Advances and Challenges in Deep Blue Emitting Quasi‐2D and Nanocrystalline Perovskite LEDs

open access: yesAdvanced Materials, EarlyView.
In this review, the recent development of deep‐blue (≤465 nm) perovskite light‐emitting diodes (PeLEDs) are summarized, using different perovskite nanomaterials, including nanocrystals (NCs), quantum dots (QDs), nanoplatelets (NPLs), quasi‐2D thin film, 3D bulk thin film, as well as lead‐free perovskite nanomaterials.

CTL+FO Verification as Constraint Solving

open access: yes, 2014
Expressing program correctness often requires relating program data throughout (different branches of) an execution. Such properties can be represented using CTL+FO, a logic that allows mixing temporal and first-order quantification.

Role of early viral surface antigens in cellular immune response to vaccinia virus [PDF]

open access: yes, 1976
Infection of mice with the vaccinia virus strain WR, Elstree or DIs, a conditional lethal mutant of vaccinia virus, resulted in the generation of vaccinia virus-specific sensitized cytolytic T lymphocytes (CTL).

Engineering CAR‐T Therapeutics for Enhanced Solid Tumor Targeting

open access: yesAdvanced Materials, EarlyView.
CART cell therapy has proven effective for blood cancers but struggles with solid tumors due to diverse antigens and complex environments. Recent efforts focus on improving CAR design and validation platforms. Advances in protein engineering, machine learning, and organoid systems aim to enhance CAR‐T therapy against solid tumors.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Revealing Trapped Carrier Dynamics at Buried Interfaces in Perovskite Solar Cells via Infrared‐Modulated Action Spectroscopy with Surface Photovoltage Detection

open access: yesAdvanced Materials, EarlyView.
A new spectroscopy technique (i.e., pump‐push‐surface photovoltage) is introduced that monitors trapped carrier dynamics at the buried interfaces in perovskite solar cells (PeSCs) via combining optical trap activation by infrared light with surface photovoltage detection.

Efficient CTL Verification via Horn Constraints Solving [PDF]

open access: yes, 2016
The use of temporal logics has long been recognised as a fundamental approach to the formal specification and verification of reactive systems. In this paper, we take on the problem of automatically verifying a temporal property, given by a CTL formula ...

Electrochemical Modulation of Hole Extraction in NiO/Perovskite Bilayers

open access: yesAdvanced Materials Interfaces, EarlyView.
The influence of hole depletion/accumulation on the hole extraction is evaluated in NiO/perovskite bilayers by transient spectroelectrochemical measurements. Metal‐halide perovskite thin films with different valence band positions are prepared, and the influence of band offset on the hole extraction kinetics is studied.
