A High-throughput Color Measurement System for Evaluating Flesh Browning in Apples

open access: yesJournal of the American Society for Horticultural Science, 2021
The development of new high-quality apple (Malus ×domestica) cultivars that are resistant to flesh browning is needed to expand the use of apples in the food service and catering industry. However, conventional methods for evaluating apple flesh browning

Combination of carbon nanotubes and two-photon absorbers for broadband optical limiting [PDF]

open access: yes, 2004
New systems are required for optical limiting against broadband laser pulses. We demonstrate that the association of non-linear scattering from single-wall carbon nanotubes (SWNT) and multiphoton absorption (MPA) from organic chromophores is a promising ...

A novel colorimetric biosensor based on non-aggregated Au@Ag core–shell nanoparticles for methamphetamine and cocaine detection [PDF]

open access: yes, 2017
We report a novel colorimetric biosensor based on non-aggregation Au@Ag core-shell nanoparticles to detect methamphetamine and cocaine. The biosensor consisted of a reporter probe (RP) that is a specific single-stranded DNA (ssDNA) sequence coated on Au ...

Evaluation of streamwater composition changes in the Vosges Mountains (NE France): 1955–2005 [PDF]

open access: yes, 2009
n 1995, in the southwestern Vosges Mountains (NE France), 158 of 395 streams (40%) had a pH lower than 5.5 at baseflow. As elsewhere in Europe, acid deposition has decreased since the seventies, as has base cation deposition.
