Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Measurement of beauty production via non-prompt charm hadrons in p–Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics
The production cross sections of D0, D+, and Λ c + $$ {\Lambda}_{\textrm{c}}^{+} $$ hadrons originating from beauty-hadron decays (i.e. non-prompt) were measured for the first time at midrapidity in proton–lead (p–Pb) collisions at the center-of-mass ...

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Prompt and non-prompt J/ψ production at midrapidity in Pb–Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics
The transverse momentum (p T) and centrality dependence of the nuclear modification factor R AA of prompt and non-prompt J/ψ, the latter originating from the weak decays of beauty hadrons, have been measured by the ALICE collaboration in Pb–Pb collisions

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

High Energy Density Physics Experiments With Intense Heavy Ion Beams [PDF]

open access: yes, 2008
The US heavy ion fusion science program has developed techniques for heating ion-beam-driven warm dense matter (WDM) targets. The WDM conditions are to be achieved by combined longitudinal and transverse space-charge neutralized drift compression of the ...

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Search for medium effects using jet axis decorrelation in inclusive jets from PbPb collisions at $$\sqrt{{s}_{\text{NN}}}$$ = 5.02 TeV

open access: yesJournal of High Energy Physics
The jet axis decorrelation in inclusive jets is studied using lead-lead (PbPb) collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The jet axis decorrelation is defined as the angular difference between two definitions of the jet axis. It

Heavy-flavor measurements in heavy-ion collisions with the ALICE experiment

open access: yesNuclear and Particle Physics Proceedings, 2016
Open and hidden heavy-flavor measurements with the ALICE experiment at the LHC are reported. Emphasis goes to the recent results in p–Pb and Pb–Pb collisions at sNN=5.02 and 2.76 TeV respectively. Heavy-flavor measurements are presented in the form of either the ratio of the production cross sections in heavy-ion and pp collisions normalized by the ...
