Mechanistic Insights into Amorphous Solid Dispersions: Bridging Theory and Practice in Drug Delivery.

Pharm Res

January 2025

Improving the bioavailability  of poorly water-soluble drugs presents a significant challenge in pharmaceutical development. Amorphous solid dispersions (ASDs) have garnered substantial attention for their capability to augment the solubility and dissolution rate of poorly water-soluble drugs, thereby markedly enhancing their bioavailability. ASDs, characterized by a metastable equilibrium where the active pharmaceutical ingredient (API) is molecularly dispersed, offer enhanced absorption compared to crystalline forms.

Exploring P-(Fe,V)-Codoped Metastable-Phase β-NiMoO for Improving the Performance of Overall Water Splitting.

Inorg Chem

January 2025

School of Materials Science and Chemical Engineering, Ningbo University, Ningbo, Zhejiang 315211, P. R. China.

It is especially essential to develop high-performance and low-cost nonprecious metal catalysts for large-scale hydrogen production. A large number of electrochemical catalysts composited by transition metal centers has been reported; however, it is still a great challenge to design and manipulate target electrocatalysts to realize high overall water-splitting activity at the atomic level. Herein, we develop totally new P-(Fe,V)-codoped metastable-phase β-NiMoO.

Ammonia electrosynthesis from nitrate using a stable amorphous/crystalline dual-phase Cu catalyst.

Nat Commun

January 2025

State Key Laboratory of Catalysis, Dalian National Laboratory for Clean Energy, iChEM (Collaborative Innovation Center of Chemistry for Energy Materials), Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian, China.

Renewable energy-driven electrocatalytic nitrate reduction reaction presents a low-carbon and sustainable route for ammonia synthesis under mild conditions. Yet, the practical application of this process is currently hindered by unsatisfactory electrocatalytic activity and long-term stability. Herein we achieve high-rate ammonia electrosynthesis using a stable amorphous/crystalline dual-phase Cu catalyst.

Single-atom catalysts have attracted a significant amount of attention due to their exceptional atomic utilization and high efficiency in a range of catalytic reactions. However, these systems often face thermodynamic instability, leading to agglomeration under the operational conditions. In this study, we investigate the interactions of 12 types of catalytic atoms (Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag, Ir, Pt, Au, and Bi) on three crystalline phases (1T, 1T', and 2H) of six transition metal dichalcogenide layers (MoS, MoSe, MoTe, WS, WSe, and WTe) using first-principles calculations.

A single residue switch mediates the broad neutralization of Rotaviruses.

Nat Commun

January 2025

State Key Laboratory of Vaccines for Infectious Diseases, Xiang An Biomedicine Laboratory, School of Life Sciences, School of Public Health, Xiamen University, Xiamen, PR China.

Broadly neutralizing antibodies (bNAbs) could offer escape-tolerant and lasting protection against viral infections and therefore guide development of broad-spectrum vaccines. The increasing challenge posed by viral evolution and immune evasion intensifies the importance of the discovery of bNAbs and their underlying neutralization mechanism. Here, focusing on the pivotal viral protein VP4 of rotavirus (RV), we identify a potent bNAb, 7H13, exhibiting broad-spectrum neutralization across diverse RV genotypes and demonstrating strong prevention of virus infection in female mice.
