Visible Light Actuated Efficient Exclusion Between Plasmonic Ag/AgCl Micromotors and Passive Beads
(Wiley Periodicals, Inc., 2018-11)
Insight is provided into the collective behavior of visible‐light photochemically driven plasmonic Ag/AgCl Janus particles surrounded by passive polystyrene (PS) beads. The active diffusion of single Janus particles and ...
Janus Micromotors: High‐Motility Visible Light‐Driven Ag/AgCl Janus Micromotors (Small 48/2018)
(Wiley Periodicals, Inc., 2018-11)
Nanoengineered Colloidal Probes for Raman‐based Detection of Biomolecules inside Living Cells
(WILEY‐VCH Verlag, 2013-02-11)
Environmentally Responsive Core/Shell Particles via Electrohydrodynamic Co-Jetting of Fully Miscible Polymer Solutions
(WILEY-VCH Verlag, 2008-10)
Herein it is demonstrated that electrohydrodynamic co-jetting is not limited to Janus-type particles, but can also be used for the preparation of core/shell particles. Using side-by-side flow of miscible polymer solutions, ...
Two‐Photon Fluorescence Imaging Super‐Enhanced by Multishell Nanophotonic Particles, with Application to Subcellular pH
(WILEY‐VCH Verlag, 2012-07-23)
A novel nanophotonic method for enhancing the two‐photon fluorescence signal of a fluorophore is presented. It utilizes the second harmonic (SH) of the exciting light generated by noble metal nanospheres in whose near‐field ...
GaN/air gap based micro-opto-electro-mechanical (MOEM) Fabry-PÉrot filters
(WILEY-VCH Verlag, 2007-06)
Structural and optical properties of Fabry-PÉrot filters (FPFs) with GaN/air gap based distributed Bragg reflectors (DBRs) were studied. Reflectance of GaN/air gap DBRs on sapphire substrate was calculated from the standard ...
Risk Governance of Emerging Technologies Demonstrated in Terms of its Applicability to Nanomaterials
(ElsevierWiley Periodicals, Inc., 2020-09)
Nanotechnologies have reached maturity and market penetration that require nano- specific changes in legislation and harmonization among legislation domains, such as the amendments to REACH for nanomaterials (NMs) which ...
Future directions of positron annihilation spectroscopy in low-k dielectric films
(WILEY-VCH Verlag, 2007-09)
Positronium Annihilation Lifetime Spectroscopy (PALS) has become recognized in the microelectronics industry as one of only several methods capable of quantitatively characterizing engineered nanopores in next-generation ...
Femtosecond pump-probe studies of carrier transport and gain dynamics in quantum cascade lasers
(WILEY-VCH Verlag, 2008-01)
Time-resolved pump-probe differential transmission measurements have been performed on various sets of quantum cascade lasers below and above threshold. Bias-, temperature-, and polarization dependent studies enable a ...
