On‐Surface Synthesis of B3N3‐Substituted Two‐Dimensional Covalent Organic Frameworks with Distinct Pore Sizes and Kagome Band Structures

Small, Volume 22, Issue 32, 8 June 2026.
Single‐layer, 2D BN‐substituted covalent organic frameworks (COFs) with two distinct periodicities are synthesized on noble metal supports. A multi‐method characterization reveals a non‐planar, chiral structure. Band gaps and frontier band dispersion are controlled by linker chemistry and spacer extension.

Gallium‐Assisted Platinum Isolation: Formation of Multiple Pt Species in Ga‐Pt Liquid Metal Catalysts

Small Structures, Volume 7, Issue 6, June 2026.
Coexistence of multiple Pt species, i.e., single atom like Pt, 2D Pt rafts, on Pt‐depleted liquid Ga‐Pt alloys, is elucidated by correlative XPS and STEM measurements. Additionally, promotion of the spatial‐isolated Pt formation on liquid Ga is furthermore revealed.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

A Control Strategy for Variable Speed Condenser Based on Doubly‐Fed Machine

IET Smart Energy Systems, Volume 2, Issue 2, Page 120-130, June 2026.
This paper proposes a variable speed condenser (VSC) control strategy based on a doubly fed machine. It can be installed in PV stations and wind farms to enhance the grid‐connection performance of renewable energy power plants. ABSTRACT The lack of active power support capability in power systems with large‐scale renewable energy integration has become
