Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

On the Theory of Condensation [PDF]

open access: yesProgress of Theoretical Physics, 1956
The Mayer-Born-Kahn-Uhlenbeck theory of imperfect gases and condensation phenomena has treated the ideal systems, for which the volume dependence of the cluster integrals is completely neglected, but the present paper treats the real systems, for which the volume dependence of the cluster integrals is rigorous! y taken into consideration.

Optical Control of the Thermal Conductivity in BaTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter

Kinetic energy generation in heat engines and heat pumps: the relationship between surface pressure, temperature and circulation cell size

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2017
The pattern and size of the Earth’s atmospheric circulation cells determine regional climates and challenge theorists. Here the authors present a theoretical framework that relates the size of meridional cells to the kinetic energy generation within them.

Bose-Einstein condensation of magnons under incoherent pumping

open access: yes, 2008
Bose-Einstein condensation in a gas of magnons pumped by an incoherent pumping source is experimentally studied at room temperature. We demonstrate that the condensation can be achieved in a gas of bosons under conditions of incoherent pumping. Moreover,

The Condensation of Helium [PDF]

open access: yesNature, 1908
I HAVE just read with great interest of Prof. Onnes's experiments with helium, and as one who has carried out investigations at very low temperatures, and to a certain extent in the same direction, I must congratulate him on having overcome difficulties of no ordinary nature.

Imaging of Lipid Droplets in Living Cells and Mice with Metabolic Dysfunction‐Associated Steatotic Liver Disease via a Galactose‐Modified Supramolecular Near‐Infrared Fluorescent Glycoprobe

open access: yesAdvanced Functional Materials, EarlyView.
A galactose‐modified supramolecular near‐infrared (NIR) glycoprobe, TCF‐FBN@Gal‐BSA, enables targeted delivery to the liver through the asialoglycoprotein receptor (ASGPR) and facilitates liver‐targeting fluorescence visualization of lipid droplets (LDs) in metabolic dysfunction‐associated steatotic liver disease (MASLD) mice.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
