Electrotunable friction with ionic liquid lubricants: how important is the molecular structure of the ions? [PDF]

open access: yesarXiv, 2015
Using non-equilibrium molecular dynamics simulations and a coarse grained model of ionic liquids, we have investigated the impact that the shape and the intramolecular charge distribution of the ions have on the electrotuneable friction with ionic-liquid nanoscale films. We show that the electric-field induces significant structural changes in the film,

A Sustainable Route From Quartz to Bifunctional Material with Adsorbed Lanthanides for Enhanced Fluorescent Activation in Doxycycline Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
The aim of this study is to develop a sensor material based on natural quartz combined with La(III) and Ce(III), both detected in Ni‐MH batteries, as well as Eu(III), for reliable qualitative and quantitative analysis of doxycycline over a broad concentration range.

High‐Performance n‐Type OFETs Enabled by Pyridine‐Substituted Diketopyrrolopyrrole Organic Semiconductor and Elastomer Stretchable Blends

open access: yesAdvanced Materials Technologies, EarlyView.
Two n‐type small molecules (DPPPy‐C10‐TN and DPPPy‐C‐Si‐TN) based on alkyl/siloxane‐substituted pyridine flanked diketopyrrolopyrrole (DPPPy) end capped with thienyl naphthalimide (TN) for organic filed effect transistors (OFETs) are reported. Interestingly, bottom‐gate top‐contact OFETs based on DPPPy‐C‐Si‐TN:SEBS blend show a high electron mobility ...

Polarization‐Dependent Color Modulation in Electrodeposited Cellulose Nanocrystals and Birefringent Multilayers

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates that wavelength selective reflection of circularly polarized light (CPL) of both handedness (right‐R or left‐L) can be achieved from self‐assembled cellulose nanocrystals (CNCs), breaking the inherent limitation of obtaining only L‐CPL reflection.

Wide Color Gamut and High Sensitivity in Luminescent Thermal Indicators from an Organic Energy Donor‐Acceptor System with Tunable Molecular Interactions

open access: yesAdvanced Optical Materials, EarlyView.
A novel energy donor‐acceptor system based on organic small molecules is studied and applied in thermally responsive thin films. Their photoluminescence is gradually tuned as a function of the annealing temperature, resulting in an attractive property for quality control and thermal patterning technologies. The films are evaluated as thermal indicators,

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

open access: yesAdvanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...
