Investigating the synergistic effects of hybrid and bimodal filler networks on the out-of-plane thermal conductivity of polymer composites

Published on 2026-06-12 by Yonghyun Albert Kwon, Jaeyeon Kim, Jiseon Choi, Soojeong Jeong, Yunchan Lee, Ho Sun Lim, Jeong Ho Cho @NATURE

Abstract: Polymer Journal, Published online: 12 June 2026; doi:10.1038/s41428-026-01220-2We report a highly effective approach to improve the out-of-plane thermal conductivity of polymer prepregs by optimizing filler networks. Comparing monofiller, hybrid (h-BN/Al2O3), and bimodal (h-BN aggregates/powders) systems reveal that bimodal architectures successfully balance isotropic phonon transport with minimized interfacial thermal resistance. By utilizing chemically identical h-BN fillers with distinct morp[...]


Our summary: The study investigates the impact of hybrid and bimodal filler networks on the thermal conductivity of polymer composites. Bimodal architectures enhance phonon transport while reducing thermal resistance. The optimized prepreg achieves a thermal conductivity of 0.56 W/m·K with 25 wt% filler.

Federated hierarchical data management using uniform object locator ranges

Patent published on the 2026-06-11 in US under Ref US20260161665 by BOYNTON JON LEE [US] (Boynton Jon Lee [us])

Abstract: [0000] A system and method for managing distributed hierarchical data using Uniform Object Locator (UOL) ranges in a federated network. A master node maintains a centralized registry of non-overlapping UOL range entries to filter and route create, read, update, delete (CRUD) operations and search queries exclusively to the affiliate node(s) responsible for each UOL key. Range entries are of consecutive or collated type and employ specialized comparison logic that respects both lexicographic and [...]


Our summary: A system manages distributed hierarchical data using Uniform Object Locator ranges. A master node maintains a registry to filter and route CRUD operations to responsible affiliate nodes. The architecture eliminates data replication and supports scalable management of deep hierarchies.

Emergent bulk-edge states and edge-topology control in weakly coupled multimer SSHN models

Published on 2026-05-14 by Zheng-Fang Liu, Qing-Ping Wu and Xian-Bo Xiao @IOP SCIENCE

Abstract: The generalized Su–Schrieffer–Heeger (SSHN) model, featuring multiple sites per unit cell, provides a rich platform for exploring topological phases beyond the conventional dimerized chain. In this work, we systematically investigate edge-state physics in SSHN models composed of weakly coupled multimers under open boundary conditions. By analyzing systems with N = 3 to 6, we establish a systematic relation between the edge multimer configuration (such as monomer–dimer or dimer–dimer)[...]


Our summary: This study investigates edge-state physics in generalized Su–Schrieffer–Heeger models with weakly coupled multimers.
