Two-color XUV plus NIR femtosecond photoionization of neon in the near-threshold region
(IOP Publishing, 2019-06-28)
Results of angle-resolved electron spectroscopy of near-threshold photoionization of Ne atoms by combined femtosecond extreme ultraviolet and near infrared fields are presented. The dressed-electron spectra show an energetic ...
Effect of surface plasmon resonance in TiO2/Au thin films on the fluorescence of self-assembled CdTe QDs structure
(IOP Publishing, 2015)
The exceptional properties of localised surface plasmons (LSPs), such as local field enhancement and confinement effects, resonant behavior, make them ideal candidates to control the emission of luminescent nanoparticles. ...
Advances in Click Chemistry for Single-Chain Nanoparticle Construction
(MDPI, 2013-03)
Single-chain polymeric nanoparticles are artificial folded soft nano-objects of ultra-small size which have recently gained prominence in nanoscience and nanotechnology due to their exceptional and sometimes unique properties. ...
Metal-Free Polymethyl Methacrylate (PMMA) Nanoparticles by Enamine "Click" Chemistry at Room Temperature
(MDPI, 2011-12)
"Click" chemistry has become an efficient avenue to unimolecular polymeric nanoparticles through the self-crosslinking of individual polymer chains containing appropriate functional groups. Herein we report the synthesis ...
Surface state tunable energy and mass renormalization from homothetic quantum dot arrays
(Royal Society of Chemistry, 2019-12-28)
Quantum dot arrays in the form of molecular nanoporous networks are renowned for modifying the electronic surface properties through quantum confinement. Here we show that, compared to the pristine surface state, the band ...
Acoustic plasmons in extrinsic free-standing graphene
(IOP Publishing, 2014-08-04)
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...
Advances in Single-Chain Nanoparticles for Catalysis Applications
(MDPI, 2017-10-21)
Enzymes are the most efficient catalysts known for working in an aqueous environment near room temperature. The folding of individual polymer chains to functional single-chain nanoparticles (SCNPs) offers many opportunities ...
Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation
(Hindawi Publishing, 2015)
Single-chain technology (SCT) allows the transformation of individual polymer chains to folded/collapsed unimolecular soft nanoparticles. In this work we contribute to the enlargement of the SCT toolbox by demonstrating ...
Motions of Water and Solutes-Slaving Versus Plasticization Phenomena
(American Institute of Physics, 2019-03-28)
It is well-accepted that hydration water is crucial for the structure, dynamics, and function of proteins. However, the exact role of water for the motions and functions of proteins is still debated. Experiments have shown ...
Advances in Fluorescent Single-Chain Nanoparticles
(MDPI, 2017-10-26)
Fluorophore molecules can be monitored by fluorescence spectroscopy and microscopy, which are highly useful and widely used techniques in cell biology, biochemistry, and medicine (e.g., biomarker analysis, immunoassays, ...
