Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Emerging of Anomalous Higher‐Order Topological Phases in Altermagnet/Topological Insulator Heterostructure by Floquet Engineering

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

Surface Functional Renormalization Group for Layered Quantum Materials

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
This work introduces surface functional renormalization group, a powerful method for studying strong electron correlations at surfaces of layered quantum materials. Applying it to a 3D Hubbard‐SSH model reveals how bulk coupling reshapes surface phases, uncovering regimes of antiferromagnetism, ferromagnetism, d‐wave superconductivity, and possible ...

Nonequilibrium Photothermal Reactions Under Pulsed Laser Excitation: Mechanisms, Dynamics, and Applications

open access: yesChemCatChem, Volume 18, Issue 7, 14 April 2026.
ABSTRACT Pulsed laser excitation offers a compelling approach for accessing nonequilibrium conditions in catalysis by delivering energy to surfaces in a highly localized and time‐controlled manner. In contrast to continuous‐wave irradiation, pulsed lasers concentrate energy into extremely short bursts—ranging from femtoseconds to nanoseconds—which can ...

Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1727-1742, April 2026.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.
