Fabrication of gold nanoparticles in Therminol VP-1 by laser ablation and fragmentation with fs pulses
(IOP Science, 2014-10-22)
This letter reports on a physical method to produce highly pure, size-controlled and well-dispersed spherical gold nanoparticles (NPs) in Therminol VP-1 by pulsed laser ablation in liquids (PLAL) using a 30 fs Ti:Sapphire ...
Suppressing H2 Evolution and Promoting Selective CO2 Electroreduction to CO at Low Overpotentials by Alloying Au with Pd
(2019-03-11)
CO2 electroreduction is a promising technology to produce chemicals and fuels from renewable resources. Polycrystalline and nanostructured metals have been tested extensively while less effort has been spent on understanding ...
Valley Hall phases in kagome lattices
(American Physical Society, 2019)
We report the finding of the analogous valley Hall effect in phononic systems arising from mirror symmetry
breaking, in addition to spatial inversion symmetry breaking. We study topological phases of plates and
spring-mass ...
Selective Growth of Layered Perovskites for Stable and Efficient Photovoltaics
(Royal Society of Chemistry, 2018-11)
Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power
conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under
operation ...
Counterbalance between Surface and Confinement Effects As Studied for Amino-Terminated Poly(propylene glycol) Constraint in Silica Nanopores
(American Chemical Society, 2019)
Broadband dielectric spectroscopy (BDS) and orthopositronium annihilation lifetime spectroscopy (PALS) are combined to study the
molecular dynamics and the free volume of poly(propylene glycol) terminated
with amino end ...
Diffraction-Based Phase Calibration of Spatial Light Modulators With Binary Phase Fresnel Lenses
(IEEE, 2016)
We propose a simple and robust method to determine the calibration function of phase-only spatial light modulators (SLMs). The proposed method is based on the codification of binary phase Fresnel lenses (BPFLs) onto an ...
Molecular Characterization of the Viroporin Function of Foot-and-Mouth Disease Virus Nonstructural Protein 2B
(American Society for Microbiology, 2018-12)
Nonstructural protein 2B of foot-and-mouth disease (FMD) virus (FMDV) is comprised of a small, hydrophobic, 154-amino-acid protein. Structure-function analyses demonstrated that FMDV 2B is an ion channel-forming protein. ...
Corneal relaxation time estimation as a function of tear oxygen tension in human cornea during contact lens wear
(John Wiley & Sons, 2019-12-03)
The purpose is to estimate the oxygen diffusion coefficient and the relaxation time of the cornea with respect to the oxygen tension at the cornea–tears interface. Both findings are discussed. From the experimental data ...
Relative Impacts of Methylammonium Lead Triiodide Perovskite Solar Cells Based on Life Cycle Assessment
(Elsevier, 2017-11-22)
The environmental performance of four different device assembly procedures based on
hybrid halide perovskite solar cell (PSC) were assessed from cradle to grave using life
cycle assessment (LCA) methodology. In addition, ...
Effect of the Endosomal Acidification on Small Ion Transport through the Anthrax Toxin PA63 Channel
(Wiley, 2017-11)
Tight regulation of pH is critical for the structure and function of cells and organelles. The pH environment changes dramatically along the endocytic pathway, an internalization transport process that is ‘hijacked’ by ...
