A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Recent Advances in Bimetallic Site Catalysts for Photocatalytic Ammonia Synthesis: Synergistic Effects and Design Strategies

Small, EarlyView.
Photocatalytic ammonia synthesis employs photocatalysts to harness solar energy, driving the reduction of N2 into NH3. The synergistic effects of bimetallic active sites are used to overcome limitations of single‐metal systems and optimize electronic structures.

Near‐Armchair‐Enriched Growth of Single‐Walled Carbon Nanotubes via W‐Containing Fe‐Based Catalyst Systems in Mist FC‐CVD

Small, EarlyView.
A mist‐based floating catalyst chemical vapor deposition (mist FC‐CVD) strategy allows the use of non‐volatile precursors and multi‐component catalyst delivery in a continuous process. Through catalyst composition control, it generates near‐armchair‐enriched single‐walled carbon nanotubes (SWCNTs) and uncovers key factors governing chiral‐angle ...
