Thermally Conductive Hexagonal Boron Nitride/Polymer Composites for Efficient Heat Transport
Advanced Functional Materials, Volume 34, Issue 46, November 12, 2024.Electrically insulating and highly thermally‐conducting h‐BN flakes can be incorporated as thermal fillers to impart high κ to polymer‐based thermal interface materials. A cellulose‐based composite embedded with FLh‐BN flakes, achieving a κ of up to ≈21.7 W m−1 K−1 is demonstrated, using a cost‐effective, simple, and scalable processing procedure ...

Paleoceanography and Paleoclimatology, Volume 39, Issue 11, November 2024.Abstract The timing and duration of oceanic disturbances linked to Oceanic Anoxic Event (OAE) 1b, as well as the mechanisms driving anoxia and carbon burial during this period, remain subjects of debate. We conducted cyclostratigraphic analyses on magnetic susceptibility (MS) and elemental Ti and Fe series within the upper Aptian‐lower Albian interval ...

Space Weather, Volume 22, Issue 11, November 2024.Abstract On 10 May 2024, a severe geomagnetic storm coinciding with Mother's Day in Mexico lasted over 40 hr and produced polar auroras observable at low latitudes. This storm, the most intense since 2003, resulted from a series of solar flares and coronal mass ejections from active region 3664.

Geobiology, Volume 22, Issue 6, November/December 2024.ABSTRACT Banded iron formations (BIFs) are chemical sedimentary rocks commonly utilized for exploring the chemistry and redox state of the Precambrian ocean. Despite their significance, many aspects regarding the crystallization pathways of iron oxides in BIFs remain loosely constrained.
