Nanosecond Molecular Motion in pHP1α Liquid-Liquid Phase Separation Captured by Solid-State NMR.

The relationship among protein structure, function, and dynamics is fundamental to biological activity, particularly in more complex biomolecular systems. Solid-state and solution-state NMR techniques offer powerful means to probe these dynamics across various time scales. However, standard assumptions about molecular motion are often challenged in phase-separated systems like phosphorylated heterochromatin protein 1 alpha (pHP1α), which exhibit both solid- and solution-like characteristics.

Harnessing Hole Sites in 2D Monolayer C for Metal Cluster Anchoring.

Synthesis of 2D quasi-hexagonal phase C (qHP C) has opened avenues for its application as a novel catalytic support. This study investigates the structure, stability, and anisotropic properties of Cu clusters anchored on the qHP C surface through density functional theory calculations. Our findings reveal that the Cu cluster preferentially occupies the intrinsic holes of the qHP C via one of its tetrahedral faces, resulting in enhanced stability and conductivity, with a significantly reduced band gap of 0.

Environmental Catalysis for NO Reduction by Manipulating the Dynamic Coordination Environment of Active Sites.

Nowadays, it is challenging to achieve SO-tolerant environmental catalysis for NO reduction because of the thermodynamically favorable transformation of reactive sites to inactive sulfate species in the presence of SO. Herein, we achieve enhanced low-temperature SO-tolerant NO reduction by manipulating the dynamic coordination environment of active sites. Engineered by coordination chemistry, SiO-CeO composite oxides with a short-range ordered Ce-O-Si structure were elaborately constructed on a TiO support.

Topological defects induced by air inclusions in ferroelectric nematic liquid crystals with ionic doping.

We report an experimental study on how topological defects induced by cylindrical air inclusions in the ferroelectric nematic liquid crystal RM734 are influenced by ionic doping, including an ionic surfactant and ionic polymer.

From Radical Coupling to Enantioselective Controlled Protonation: Advancing Precise Construction of Stereocenters.

Recent advancements in green and sustainable platforms, particularly visible light-driven photocatalysis, have spurred significant progress in radical chemistry, enabling the efficient synthesis of important molecules from simple and readily available feedstocks under mild conditions.

SpaGraphCCI: Spatial cell-cell communication inference through GAT-based co-convolutional feature integration.

Spatially resolved transcriptomics technologies potentially provide the extra spatial position information and tissue image to better infer spatial cell-cell interactions (CCIs) in processes such as tissue homeostasis, development, and disease progression. However, methods for effectively integrating spatial multimodal data to infer CCIs are still lacking. Here, the authors propose a deep learning method for integrating features through co-convolution, called SpaGraphCCI, to effectively integrate data from different modalities of SRT by projecting gene expression and image feature into a low-dimensional space.

Lu-Labeled Heterodimeric Agent with High Stability Targeting Neovascularization for Tumor Radioligand Therapy.

Radiopharmaceutical theranostics holds significant promise in tumor diagnosis and treatment, but suboptimal tumor uptake and retention remain a persistent limitation. We have conjugated a unique albumin binder to our previously developed heterodimeric precursor HX01 and achieved a novel precursor L6, aiming to prolong circulation time and enhance tumor accumulation and retention. However, we observed that the NGR sequence of L6 was gradually rearranged to iso-DGR under alkaline conditions, resulting in decreased stability.
