Hazardous Waits: CPSC Lets Crucial Time Pass Before Warning Public About Dangerous Products [PDF]

, 2008
Despite a law requiring manufacturers to provide the Consumer Product Safety Commission (CPSC) with "immediate" notification of dangerous products, the agency typically delays nearly seven months after learning of dangerous, defective products before ...

Programmable Liquid Crystal Elastomers Via Magnetic Field Assisted Oligomerization

Advanced Functional Materials, EarlyView.
This article presents a straightforward method for designing programmable liquid crystal elastomer (LCE) actuators using magnetic field alignment. It combines thio‐Michael polyaddition for efficient LCE synthesis with a strategy that preserves the nematic phase, enabling the alignment of high molecular weight LCOs.

Soft Mode Anomalies in the Perovskite Relaxor Pb(Mg1/3Nb2/3)O3

, 2000
Neutron inelastic scattering measurements of the polar TO phonon mode in the cubic relaxor Pb(Mg1/3Nb2/3)O3, at room temperature, reveal anomalous behavior similar to that recently observed in the Pb(Zn1/3Nb2/3)_{0.92}Ti_{0.08}O3 system in which the ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Soft Phonon Anomalies in the Relaxor Ferroelectric Pb(Zn_1/3Nb_2/3)_0.92Ti_0.08O_3

, 2000
Neutron inelastic scattering measurements of the polar TO phonon mode dispersion in the cubic relaxor Pb(Zn_1/3Nb_2/3)_0.92Ti_0.08O_3 at 500K reveal anomalous behavior in which the optic branch appears to drop precipitously into the acoustic branch at a ...

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

Advanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Stable, Easy‐to‐Handle, Fully Autologous Electrospun Polymer‐Peptide Skin Equivalent for Severe Burn Injuries

Advanced Functional Materials, EarlyView.
A bioengineered skin equivalent composed of electrospun poly(ε‐caprolactone) (PCL) and the bioactive peptide Fmoc‐FRGD is developed for severe burn treatment. This scaffold promotes full‐thickness skin regeneration by supporting cellular adhesion and integration. In‐vitro and in‐vivo studies show enhanced mechanical stability, accelerated wound closure,
