TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

open access: yesAngewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Synergistic Effects in Multistate Black Electro‐Thermochromic Smart Windows for Energy‐Efficient Modulation of Solar Heating

open access: yesAdvanced Science, EarlyView.
Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...

Cartesian积与邻点可区别着色之间的关系(Relation between Cartesian product and adjacent vertex distinguishing coloring)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
A proper k-edge coloring of a graph G is an assignment of k colors 1, 2, …, k to edges of G such that any two adjacent edges receive the different colors.

Adaptive Network Stabilization Despite Profound Structural Reorganization in Human Organotypic Cultures

open access: yesAdvanced Science, EarlyView.
Adult human organotypic cortical slices undergo marked neuronal loss, laminar disruption, and glial activation, yet their network activity progressively stabilizes after a variable period. Electrophysiology, longitudinal calcium imaging, and quantitative histology show that structurally remodeled human circuits show adaptive capacity resulting in ...

Total Chromatic Number of Δ-Claw-Free 3-Degenerated Graphs

open access: yes, 2018
The total chromatic number χ"(G) of a graph G is the minimum number of colors needed to color the elements (vertices and edges) of G such that no incident or adjacent pair of elements receive the same color Let G be a graph with maximum degree Δ(G ...

Beyond Charge: Field‐Effect Transistors in Multimodal Biosensing Platforms for Biomolecular Interaction Studies

open access: yesAdvanced Electronic Materials, EarlyView.
This review summarizes the developments in field‐effect transistor (FET)‐based dual‐mode sensor platforms and what can be learned from them. It identifies charge as a crucial factor in biomolecular interactions at interfaces, outlines the challenges of hybrid systems, and highlights their benefits.

Total Colorings of Embedded Graphs with No 3-Cycles Adjacent to 4-Cycles

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A total-k-coloring of a graph G is a coloring of V ∪ E using k colors such that no two adjacent or incident elements receive the same color. The total chromatic number χ′′(G) of G is the smallest integer k such that G has a total-k-coloring.

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

open access: yesAdvanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).
