Low temperature electrostatic force microscopy of a deep two-dimensional electron gas using a quartz tuning fork

open access: yes
Using an ultralow temperature, high magnetic field scanning probe microscope, we have measured electric potentials of a deeply buried two-dimensional electron gas (2DEG).

Nano‐Raman Spectroscopy of Tellurium Nanowires

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 6, Page 1034-1039, June 2026.
Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...

Tailoring Ni‐MOFs by Microwave‐Assisted Synthesis for Efficient CO2 Methanation

open access: yesChemistrySelect, Volume 11, Issue 22, 11 June 2026.
Metal–organic frameworks (MOFs) containing Ni are efficient precursors for CO2 hydrogenation due to their tunable structures. Ni‐MOFs were synthesized solvothermally using 2‐methylimidazole with different synthesis times. The catalyst obtained after 60 min showed higher CO2 conversion, producing CO and CH4, whereas the material synthesized for 30 min ...

A Comparative Evaluation of Carbonaceous and Alloy Type Anodes for Sodium‐Ion Batteries: Capacity, Scalability, and Sustainability Perspectives

open access: yesSmall, Volume 22, Issue 31, 2 June 2026.
This review critically compares the electrochemical performance of carbon‐based and alloy‐type anodes for sodium‐ion batteries, with an emphasis on strategies that enhance practical deployment. It highlights how synergistic optimization of microstructure, electrolyte, and presodiation improves hard carbon, while nanostructuring and interfacial ...

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

open access: yesSmall, Volume 22, Issue 32, 8 June 2026.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Erosional and Hydrological Controls on the Age and Thermochemical Stability of Particulate Organic Carbon in an Arctic River

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Understanding the mechanisms that drive the mobilization and fate of organic carbon (OC) in Arctic landscapes is important for modeling the feedbacks among permafrost thaw, carbon cycling, and climate change. While significant progress has been made toward measuring in situ OC decomposition in permafrost soils and bulk particulate organic ...

Neutron Scattering Evidence for a Model of Dynamic Clustering in Molten Triacylglycerols

open access: yesJournal of Food Process Engineering, Volume 49, Issue 6, June 2026.
Number of molecules per cluster as a function of temperature. The error bars combine uncertainties from the data and from the fit to the peak functions. (A) from D5PPP; (B) from PPP. The dotted line indicates the model predictive interval and the dash‐dot line the observation prediction interval, both at 95% confidence.
