Processing Characteristics of High Molecular Weight Polyethylene in Laser Sintering: The Role of Carbon Black Concentration and Processing Strategy for Diode Laser Sintering Machines

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 11, November 2025.
Because of its high viscosity, HMWPE needs an exact adjustment between material and processing parameters as well as printing strategy. The concentration of carbon black fillers influences the processability of HMWPE in PBF‐LB/P. The mechanical properties of printed parts can be optimized by volume energy density and absorption at the optimum carbon ...

Comparative Analysis of Benchtop NMR and HPLC‐UV for Illicit Drug Mixtures

open access: yesMagnetic Resonance in Chemistry, Volume 63, Issue 11, Page 895-911, November 2025.
This study assessed benchtop NMR with Quantum Mechanical Modelling (QMM) for quantifying methamphetamine in binary and ternary mixtures. QMM achieved a root mean square error (RMSE) as low as 1.3 mg/100 mg sample, enabling simultaneous quantification of drugs, adulterants, and impurities.

Distance‐Dependent Interaction between a Single Emitter and a Single Dielectric Nanoparticle Using DNA Origami

open access: yesSmall Structures, Volume 6, Issue 11, November 2025.
In this study, dielectric nanoantennas made of silicon nanoparticles are explored as low‐loss alternatives to traditional metallic ones. Using DNA origami, their interaction with fluorophores at the single‐molecule level is investigated, observing enhanced decay rates with high quantum yield amid minimal quenching.

The Brittle‐Plastic Transition in Quartz‐Albite Mixtures: New Insights From Shear Deformation Experiments at Mid‐to‐Lower Crustal Depth Conditions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract Crustal strength is often characterized using a strength‐depth profile where laboratory‐derived friction and flow laws are connected at depth (i.e., the so‐called “Christmas Tree” diagram). Large, destructive earthquakes frequently nucleate within the transition zone from a frictional‐to‐viscous deformation regime, which represents the ...

New Insights Into the Proposed Geomagnetic Excursion Hilina Pali From High‐Resolution Lake Sediment Cores From the Polar Ural Mountains, Arctic Russia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract This study presents paleomagnetic records from three 24 m‐long sediment cores from the neighboring lakes Bolshoye Shchuch'ye and Maloye Shchuch'ye, located about 10 km apart in the Polar Urals in northern Russia. The age model, based on radiocarbon dating and varve counting, shows that the sediment sequences reach back up to about 23.5 ka cal.

The Undrained Response of Westerly Granite Subjected to Cyclical Changes in Load

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract When subjected to changes in applied stress, the pore space of rocks elastically deforms, producing changes in internal pore pressure when the pore fluid is unable to flow in or out of the stressed volume. The magnitude of this effect depends on the geometry and compliance of the pore space, which is a function of the overall microcrack ...
