Selective Solar CO2 Conversion into Ethanol Using Atomic‐Scale Copper Clusters Anchored π‐extended Poly(heptazine imide)

Small, EarlyView.
Atomic‐scale copper clusters anchored on π‐extended poly(heptazine imide) enable selective, sacrificial‐agent‐free solar conversion of carbon dioxide (CO2) to ethanol. The catalyst promotes interfacial charge separation and stabilizes key carbon‐carbon coupling intermediates, providing a molecularly defined platform for direct C2 fuel synthesis under ...

Metabolic fingerprinting of bacteria by fluorescence lifetime imaging microscopy

Scientific Reports, 2017
Bacterial populations exhibit a range of metabolic states influenced by their environment, intra- and interspecies interactions. The identification of bacterial metabolic states and transitions between them in their native environment promises to ...

Fast Injective Mesh Parameterization via Beltrami Coefficient Prolongation

Computer Graphics Forum, EarlyView.
Abstract We present a highly efficient and robust method for free boundary injective parameterization of disk‐like triangle meshes with low isometric distortion. Harmonic function–based approaches, grounded in a strong mathematical framework, are widely employed.

Deep learning-based virtual H& E staining from label-free autofluorescence lifetime images

npj Imaging
Label-free autofluorescence lifetime is a unique feature of the inherent fluorescence signals emitted by natural fluorophores in biological samples. Fluorescence lifetime imaging microscopy (FLIM) can capture these signals enabling comprehensive analyses

Measuring and modeling polymer gradients argues that spindle microtubules regulate their own nucleation

, 2017
Spindles are self-organized microtubule-based structures that segregate chromosomes during cell division. The mass of the spindle is controlled by the balance between microtubule turnover and nucleation. The mechanisms that control the spatial regulation

Epigenetic biomarker screening by FLIM-FRET for combination therapy in ER+ breast cancer

Clinical Epigenetics, 2019
Hormone-dependent gene expression involves dynamic and orchestrated regulation of epigenome leading to a cancerous state. Estrogen receptor (ER)-positive breast cancer rely on chromatin remodeling and association with epigenetic factors in inducing ER ...

A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, EarlyView.
This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.

Interferometric excitation fluorescence lifetime imaging microscopy

Nature Communications
Fluorescence lifetime imaging microscopy (FLIM) is a well-established technique with numerous imaging applications. Yet, one of the limitations of FLIM is that it only provides information about the emitting state.
