CO2-Driven Hydraulic Fracturing Trajectories across a Preexisting Fracture

Geofluids, 2021
Defining the trajectory of hydraulic fractures crossing bedding planes and other fractures is a significant issue in determining the effectiveness of the stimulation. In this work, a damage evolution law is used to describe the initiation and propagation

A Quest for the Mechanism of Ultrahigh Resolution SEM Imaging

Advanced Science, EarlyView.
Using Monte Carlo simulations with explicit definitions of SE1 and SE2 align with a cascade secondary electron production model, this work shows that the 3D nanostructure modulated SE2 emission enhances other than to reduce topographical contrast via a “miniature Faraday cup” effect.

NIR Ratiometric Fluorescent Antibody‐Drug Conjugate for Metastatic Ovarian Cancer Theranostics and Treatment Response Monitoring

Advanced Science, EarlyView.
In vivo optical imaging enhances antibody‐drug conjugate (ADC) optimization by enabling real‐time monitoring of stimulus‐responsive drug behavior. We report n501‐CYMMAF, a ratiometric theranostic with strong target affinity and low‐dose efficacy for ovarian metastasis.

Ab initio modeling of oxygen impurity atom incorporation into uranium mononitride surface and subsurface vacancies

, 2012
The incorporation of oxygen atoms has been simulated into either nitrogen or uranium vacancy at the UN(001) surface, sub-surface or central layers. For calculations on the corresponding slab models both the relativistic pseudopotentials and the method of

Defect Engineering Activates Pyrene‐Based Covalent Organic Frameworks for Efficient Photocatalytic Uranium Capture

Advanced Science, EarlyView.
A defect‐engineered pyrene‐based covalent organic framework (TP‐PYTO‐SA) is developed via strategic salicylaldehyde incorporation. This approach simultaneously enhances hydrophilicity and introduces uranyl coordination sites, while optimized defect density significantly improves charge separation.

Schwann Cell Synthesized Cholesterol Orchestrates Peripheral Nerve Regeneration via Structural and IGF1‐Dependent Signaling Mechanisms

Advanced Science, EarlyView.
This study reveals that Schwann cell FDFT1‐mediated cholesterol synthesis is essential for peripheral nerve regeneration via dual roles: as a structural component for myelin and as a metabolic signal that upregulates IGF1. IGF1 promotes axonal growth through paracrine action and enhances Schwann cell differentiation/ myelination via an intrinsic IGF1R ...
