Tritium Behavior from Vine to Wine

open access: yesApplied Sciences
The hydrogen radioactive isotope, tritium, not only reflects seasonal variation in precipitation but also variations on a local level. To use this radioisotope in authentication and geographical indication procedures, the tritium levels in vines, grapes,

New Insights in the Electrochemical Stability of Various Solid Polymer Electrolytes/Layered Positive Metal‐Oxide Electrode Interfaces in Solid‐State Lithium‐Ion Battery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
In this work, the electrochemical compatibility of a broad range of solid polymer electrolytes with two Ni‐rich nickel–manganese–cobalt cathodes (NMC622, NMC811) is investigated through a hybrid computational and experimental approach. The relative reactivity of NMC811 to NMC622 is demonstrated, as well as the role of Li cations in the electrolyte ...

One Dimensional 1H, 2H and 3H

open access: yes, 2016
The ground-state properties of one-dimensional electron-spin-polarized hydrogen $^1$H, deuterium $^2$H, and tritium $^3$H are obtained by means of quantum Monte Carlo methods.

Achieving Ultra‐Stable Hydrogen Isotope Separation Over 5000 Cycles With a High‐Loading Pd/Al2O3 Composite

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT This study successfully prepared a high‐palladium (Pd)‐loading (51 wt%) Pd/Al2O3 composite through multiple wet impregnation. The material exhibited excellent hydrogen isotope separation performance, with metal–support interactions endowing it with a higher plateau pressure and lower desorption temperature.

Bacterial Cellulose Synthase Catalyzes the Formation of Chitin

open access: yesChemistrySelect, Volume 11, Issue 15, 20 April 2026.
Recombinant BcsA‐B from Rhodobacter sphaeroides is shown to cleave UDP‐GlcNAc (uridine diphosphate N‐acetylglucosamine), generating chitin with distinct β‐chitin Raman bands. These findings reveal that a cellulose synthase can process an alternative nucleotide sugar, providing biochemical evidence for the co‐synthesis of cellulose and chitin.

Photoluminescence Enhancement in Erbium Nanoparticles via Controlled Phase Transformation

open access: yesSmall, Volume 22, Issue 24, 27 April 2026.
Er‐NPs synthesized by PLAL were thermally treated from 200°C to 1000°C. Annealing at 600°C produced a full transition to the cubic Er2O3 phase and removed non‐radiative surface species. This led to a fivefold increase in PL. The results show how oxidation and phase purity control the optical performance of Er‐NPs.

Fast ignition of inertial fusion targets by laser-driven carbon beams

open access: yes, 2009
Two-dimensional simulations of ion beam driven fast ignition are presented. Ignition energies of protons with Maxwellian spectrum and carbon ions with quasimonoenergetic and Maxwellian energy distributions are evaluated.

A Multi Tracer Approach Reveals Groundwater Residence Times and Dynamic Endmember Mixing in the Subterranean Estuary of a High Energy Beach

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Subterranean estuaries (STEs) under high‐energy conditions function as effective biogeochemical reactors, where waterbodies of varying physico‐chemical properties mix. Chemical reactions within the STE modulate the solute composition of groundwater discharging to the sea providing for example nutrients for plankton growth to coastal ecosystems.

Bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii Chatton 1914 (Dinophyceae)

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 666-688, April 2026.
Abstract Heterotrophic dinoflagellates are important predators of phytoplankton, and many species produce bioluminescence, which is thought to serve as an antipredator function. The present study investigated the bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii, an important predator of toxic and bloom‐forming dinoflagellates ...

Converting energy from fusion into useful forms

open access: yes, 2013
If fusion power reactors are to be feasible, it will still be necessary to convert the energy of the nuclear reaction into usable form. The heat produced will be removed from the reactor core by a primary coolant, which might be water, helium, molten ...
