Frequency dependent deformation reversibility during cyclic loading
<p>High-frequency testing (HFT) is useful for accelerated fatigue testing of conventional materials that typically serve under low-frequency loading conditions, as well as for the assessment of the robustness of microelectromechanical systems which typically experience high-frequency service conditions. Using discrete dislocation dynamics, we attempt to elucidate the effect of loading frequency on the reversibility of cyclic deformation. We demonstrate that the HFT induces a higher fraction of reversible cyclic deformation because of a larger portion of elastic/anelastic deformation due to limited dislocation mobility, and a higher degree of reversibility in plastic deformation owing to the less occurrence of cross-slip.</p> <p><b>IMPACT STATEMENT</b></p> <p>Dislocation-based frequency effects on high-cycle deformation reversibility in metals are elucidated. Hysteresis energy is shown to dissipate even under ideal, damage-free conditions, contrary to popular assumptions of energy-based fatigue models.</p

Multicolor Liposome Mixtures for Selective and Selectable Cargo Release
Many
approaches exist for stimuli-triggered cargo release from
nanocarriers, but few can provide for on-demand release of multiple
payloads, selectively. Here, we report the synthesis of purpurin-phospholipid
(Pur-P), a lipid chromophore that has near-infrared absorbance red-shifted
by 30 nm compared to a structurally similar pyropheophorbide-phospholipid
(Pyr-P). Liposomes containing small amounts of either Pur-P or Pyr-P
exhibited similar physical properties and fluorescence self-quenching.
Loaded with distinct cargos, Pur-P and Pyr-P liposomes were mixed
into a single colloidal suspension and selectively released cargo
depending on irradiation wavelength. Spatiotemporal control of distinct
cargo release was achieved by controlling multicolor laser placement.
Using basic orange and doxorubicin anthraquinones, multidimensional
cytotoxicity gradients were established to gauge efficacy against
cancer cells using light-released drug. Wavelength selectivity of
cargo release was maintained following intramuscular administration
to mice
