Electronic Decoupling of Polyacenes from the Underlying Metal Substrate bysp(3)Carbon Atoms
(Nature, 2020-09-15)
Many organic molecules exhibit interesting electronic and magnetic properties, but as they are deposited onto a metallic substrate, their hybridisation often impacts on the observed characteristics. Here, the authors report ...
Giant Exciton Mott Density in Anatase TiO2
(American Physical Society, 2020-09-10)
Elucidating the carrier density at which strongly bound excitons dissociate into a plasma of uncorrelated electron-hole pairs is a central topic in the many-body physics of semiconductors. However, there is a lack of ...
Even-odd Effect in Aliphatic Polycarbonates with Different Chain Lengths: from Poly (hexamethylene carbonate) to Poly (dodecamethylene carbonate)
(ACS, 2020-12-17)
We have characterized a series of aliphatic polycarbonates synthesized by organocatalysis containing a variable number of methylene groups (nCH2) in their repeat units ranging from nCH2 = 6 to 12. The melting and crystallization ...
Metal Nanoparticles/MoS2 Surface-Enhanced Raman Scattering-Based Sandwich Immunoassay for a-Fetoprotein Detection
(American Chemical Society, 2021-02-24)
The detection of cancer biomarkers at an early stage of tumor development is vital for effective diagnosis and treatment of cancer. Current diagnostic tools can often detect cancer only when the biomarker levels are already ...
How Circular Dichroism in Time and Angle-Resolved Photoemission Can Be Used to Spectroscopically Detect Transient Topological States in Graphene
(American Physical Society, 2020-10-19)
Pumping graphene with circularly polarized light is the archetype of light-tailoring topological bands. Realizing the induced Floquet-Chern-insulator state and demonstrating clear experimental evidence for its topological ...
Tunable Superparamagnetic Ring (tSPRing) for Droplet Manipulation
(Wiley-VCH, 2021-05-13)
The manipulation of droplets by magnetic field forms the basis of a fascinating technology that is currently in development. Often, the movement of droplets with magnets involves adding magnetic particles in or around the ...
An Innovative Approach for the Generation of Species of the Interstellar Medium
(Wiley, 2021-11-08)
[EN]The large amount of unstable species in the realm of interstellar chemistry drives an urgent need to develop efficient methods for the in situ generations of molecules that enable their spectroscopic characterizations. ...
Nanofocusing of acoustic graphene plasmon polaritons for enhancing mid-infrared molecular fingerprints
(De Gruyter, 2020)
Mid-infrared (mid-IR) optical spectroscopy of molecules is of large interest in physics, chemistry, and biology. However, probing nanometric volumes of molecules is challenging because of the strong mismatch of their ...
Toward Supramolecular Nanozymes for the Photocatalytic Activation of Pt(IV) Anticancer Prodrugs
(Royal Society Of Chemistry, 2020-09-16)
A supramolecular nanozyme for the photocatalytic conversion of a Pt(IV) anticancer complex to cisplatin is described herein. We employed 1.9 nm Au nanoparticles decorated with thiol ligands bearing a TACN (1,4,7-triazacyclononane) ...
How to make ecological models useful for environmental management
(Elsevier, 2019)
Understanding and predicting the ecological consequences of different management alternatives is becoming increasingly important to support environmental management decisions. Ecological models could contribute to such ...
