Monolithic Opto‐Acoustic Synesthetic Transduction of Color and Sound in a Single Chiral Liquid Crystal Elastomer

open access: yesSmall, EarlyView.
Monolithic cholesteric liquid crystal elastomers simultaneously generate color and sound under electrically programmed stimuli. Low‐frequency electric fields modulate the helical pitch to produce tunable structural colors, while high‐frequency excitation induces membrane vibration for acoustic emission.

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

open access: yesSmart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

A digital data acquisition system optimized for spectrometry with liquid scintillation detectors

open access: yes, 2006
The prototype of a new concept FPGA-based digital acquisition board has been developed for application with scintillation detectors. The board performs digitisation of pulses at 200 MSamples/s with 14-bit resolution.

Hot Injection Synthesis of Ultrathin Bi2Se3 Nanosheets With Controllable Dimensions

open access: yesSmall Methods, EarlyView.
Graphic of hot‐injection method for synthesizing Bi2Se3${\rm Bi}_2{\rm Se}_3$ nanoplatelets of controlled shape, thickness, and lateral size. The ultra‐thin regime is achievable, which is interesting for studying topological phase transitions. ABSTRACT In this work, a synthesis method for colloidal nanoplatelets (NPLs) of the topological insulator ...

A Test of the Coase Conjecture Using Prices of Electronic Books

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.
