Proof-of-Concept Experiments for Negative Ion Driver Beams for Heavy Ion Fusion [PDF]

open access: yes, 2003
Negative halogen ion beams have recently been proposed as heavy ion fusion drivers. They would avoid the problem of electron accumulation in positive ion beams, and could be efficiently photo-detached to neutrals if desired.

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

open access: yesAdvanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Isospin effects in heavy-ion collisions: some results from CHIMERA experiments at LNS and perspectives with radioactive beams

open access: yes, 2009
CHIMERA is a 4π multidetector for charged particles available at Laboratori Nazionali del Sud (INFN‐LNS). A new method to measure the time scale of the emission of nuclear fragments is described, together with some applications in the field of the ...

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

open access: yesAdvanced Functional Materials, EarlyView.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

Controlled Engineering of 2D Alkali‐Iron‐Chloride Compounds and Lateral Quantum Heterostructures Within Confined Graphene Nanoreactors

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a programmable atomic engineering strategy for 2D materials using Å‐scale nanoreactors formed by bilayer graphene (BLG) intercalation. A new class of alkali‐iron‐chloride compounds, along with lateral heterostructures composed of monolayer alkali halides and iron chlorides, is revealed.

Measurement of ψ(2S) to J/ψ cross-section ratio as function of multiplicity in pPb collisions at s NN = 8.16 $$ \sqrt{s_{\textrm{NN}}}=8.16 $$ TeV

open access: yesJournal of High Energy Physics
The production ratio of ψ(2S) to J/ψ charmonium states is presented as a function of multiplicity in proton-lead collisions at a centre-of-mass energy of s NN = 8.16 $$ \sqrt{s_{\textrm{NN}}}=8.16 $$ TeV, for both prompt and nonprompt sources.

Measurement of Λc+ Baryon Production in p–Pb Collisions with ALICE at the LHC

open access: yesProceedings, 2019
Charmed baryons and their corresponding baryon-to-meson ratios are important tools to understand hadronisation processes in the Quark-Gluon Plasma produced in heavy-ion collisions.

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.
