Structure and Zeta Potential of Gold Nanoparticles with Coronas of Varying Size and Composition.
J Phys Chem C Nanomater Interfaces
February 2025
The structure of the soft ligand shell in engineered nanoparticles is related to their physical and chemical properties. The variation in that structre is critical for extending the diversity of functions in a wide variety of applications. To uncover the structure of soft PAH coronas wrapped on gold nanoparticles (AuNPs), in particular, we used atomistic simulations in this work.

Angew Chem Int Ed Engl
October 2023
Article Synopsis
- Scientists have been trying to design better catalysts (like helpers for chemical reactions) using computers, but they haven't been super successful because they haven’t paid attention to important details about how the reactions actually work.
- A new method called CODER has been created that focuses on these important details, mixing computer help with the knowledge of researchers.
- Using CODER, they made new Pd catalysts that work really well for making materials used in electronics, and these new catalysts are way more efficient than older ones!
Highly Regioselective Cobalt-Catalyzed Hydroboration of Internal Alkynes.
Angew Chem Int Ed Engl
September 2022
Article Synopsis
- The study introduces new cobalt (Co) complexes with cyclopropane-based diphosphine ligands that effectively catalyze hydroboration reactions of unsymmetrical internal alkynes with high selectivity.
- A notable feature of these reactions is their unusual regioselectivity, showing strong cis-β-addition preference for aryl alkyl internal alkynes and cis-α-addition for dialkyl ones, which cannot be achieved with existing methods.
- Mechanistic investigations suggest that a Co-H species is the active catalyst, and the unique structure of the ligands contributes to the observed regioselectivity, making these reactions valuable for synthesizing specific alkenylborates and alkenes.
Article Synopsis

- The paper presents a networked ground station with multiple nodes that collaborate for efficient data transmission, utilizing a cloud computing model for coordination.* -
- On-orbit experiments validate the design, demonstrating strong data transmission performance and successful completion of the satellite mission.*
Spacecraft formation flying (SFF) in highly elliptical orbit (HEO) has attracted much attention since many applications in space explore, while precise guidance navigation and control (GNC) technology, especially precise ranging, conducted the basis of success for such SFF missions. In this paper, we introduced a novel K band microwave ranging (MWR) equipment that aimed for the on-orbit verification of submillimeter level precise ranging technology in future HEO SFF missions. The ranging technique is a synchronous dual one-way ranging (DOWR) microwave phase accumulation system, which achieved tens of microns of ranging accuracy in laboratory environment.
