Electrical Step‐Edge Contact to a Topological Superconductor Candidate 2M‐WS2

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
This work develops a step‐edge contact technique for encapsulated 2M‐WS2, effectively protecting the material from contamination and achieving ultralow contact resistance ( 65 µm). Highly transparent interfaces, as evidenced by Andreev reflection, enable the observation of intrinsic superconducting properties.

Fabrication of Sustainable 3D Printed Anisotropic Bonded Magnets Using Recycled Nd–Fe–B Powder and Low CO2 Footprint Polyamide 12

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
Researchers develop a sustainable way to 3D‐print high‐performance Nd–Fe–B magnets using recycled material from end‐of‐life magnets. By combining anisotropic recycled powder with a low‐carbon polyamide matrix, they achieve complex shapes and over 60% better magnetic performance than previous recycled options, offering a promising path toward a more ...

Elimination of Threshold Singularities in the Relation Between On-Shell and Pole Widths

open access: yes, 2002
In a previous communication by two of us, Phys. Rev. Lett. 81, 1373 (1998), the gauge-dependent deviations of the on-shell mass and total decay width from their gauge-independent pole counterparts were investigated at leading order for the Higgs boson of

Competition between plaquette and dimer phases in Heisenberg chains

open access: yes, 1997
We consider a class of one-dimensional Heisenberg spin models (plaquette chains) related to the recently found 1/5-depleted square-lattice Heisenberg system $CaV_4O_9$.

Modular reactor for in situ X‐ray scattering, spectroscopy and ATR‐IR studies of solvothermal nanoparticle synthesis

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 1, Page 142-153, January 2026.
A reactor is described, whose modular design enables in situ X‐ray scattering and spectroscopy, infrared spectroscopy, gas and liquid injection under autoclave‐like conditions and magnetic stirring for solvothermal synthesis up to 200°C and 8 bar.Understanding the chemical processes that occur during the solvothermal synthesis of functional ...

Nitrogen Economy Strategies Define Distinct Functional Groups of Genotypes in a Miscanthus sinensis Progeny

open access: yesGCB Bioenergy, Volume 18, Issue 1, January 2026.
Substantial intergenotypic variation in nitrogen uptake and recycling traits was observed in a M. sinensis progeny. This variability defined three functional groups with contrasting nitrogen‐use strategies, offering a framework for selecting ideotypes tailored to different environments while maintaining high biomass production under nitrogen‐limited ...

Canadian Wildfire Smoke Episode over Europe in October 2023: Lidar, Sun-Photometer, and Model Characterization of Smoke Layers Observed Above Sofia, Bulgaria

open access: yesRemote Sensing
Massive wildfires release enormous amounts of biomass-burning (BB) aerosols into the atmosphere, which might have a major impact on its thermal and radiative budget, as well as the environment and human health.

Non-equilibrium quantum dynamics of ultra-cold atomic mixtures: the multi-layer multi-configuration time-dependent Hartree method for bosons

open access: yesNew Journal of Physics, 2013
We develop and apply the multi-layer multi-configuration time-dependent Hartree method for bosons, which represents an ab initio method for investigating the non-equilibrium quantum dynamics of multi-species bosonic systems.

Quark-Loop Amplitudes for W^+- H^-+ Associated Hadroproduction

open access: yes, 1999
In this addendum to our paper entitled "W^+- H^-+ Associated Production at the Large Hadron Collider" [Phys. Rev. D 59, 015009 (1999)], we list analytic results for the helicity amplitudes of the partonic subprocess gg -> W^-H^+ induced by virtual quarks.

Perceived disabling physical pain and suicidal ideation in aging people living with HIV cured of hepatitis C: A multi‐center survey in France (ANRS CO13 HEPAVIH)

open access: yesHIV Medicine, Volume 27, Issue 1, Page 106-119, January 2026.
Abstract Introduction Suicidal ideation (SI) is highly prevalent among people living with HIV (PWH) and those with chronic hepatitis C virus (HCV) infection. Individuals with long‐term HIV–HCV co‐infection face specific health challenges, including heightened physical pain.
