Schematic diagram of the measurement system and experimental procedure.

<p>(A) ECG and radial artery pressure waveforms (RAPW) signals were synchronously recorded with a sampling rate of 1000 Hz and were converted into digital signals using a 16-bit A/D data acquisition card. (B) Auscultatory systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded manually at the beginning and end of the signal recording (more than one minute) for each subject.</p

Coherent Acoustic Phonon Dynamics of Gold Nanorods and Nanospheres in a Poly(vinyl alcohol) Matrix and Their Temperature Dependence by Transient Absorption Spectroscopy

The ultrafast dynamics of photoexcited gold nanorods (Au NRs) and gold nanospheres (Au NSs) dispersed in poly­(vinyl alcohol) (PVA) films were investigated at various temperatures. The extensional mode of the coherent acoustic phonon vibration for Au NRs and breathing mode for Au NSs were both observed. For Au NRs, the vibrational periods in PVA decreased, and those in aqueous solution increased compared to the estimated periods in vacuum. These phenomena were not observed for Au NSs. When the temperature decreased from 296 to 10 K, the vibrational period of Au NRs (9 nm diameter, 46 nm length) decreased by 15%, but the decrease was only 3% for that of Au NSs (108 nm diameter). The environmental effects on coherent acoustic phonon vibrations for Au NRs were discussed in terms of mechanical interaction with the polymer matrix and liquid–solid coupling with the solution. A simplified model for the coupling of a vibrating rod to a viscoelastic environment, called a pile–soil interaction, was introduced for Au NRs in a PVA matrix, and the calculated periods were in good agreement with the experimental data. Our results indicate that viscous effects dominate for nanorods in water, whereas elastic effects dominate in PVA, resulting in frequency shifts with opposite signs. Moreover, because of the different interaction for extensional and breathing modes, the environmental sensitivity of Au NRs is obviously higher than that of Au NSs, and this difference can provide guidelines for mechanical applications of metal–polymer nanocomposites

Dimerization Control in the Self-Assembly Behavior of Copillar[5]arenes Bearing ω‑Hydroxyalkoxy Groups

Two novel copillar[5]­arenes bearing ω-hydroxyalkoxy groups are synthesized and their self-assembly properties are studied by ¹H NMR spectroscopy, specific viscosity, and X-ray measurements. The copillar[5]­arene <b>2b</b> bearing a 6-hydroxyhexyloxy group exhibits a reversible self-assembly behavior, leading to the formation of the self-inclusion monomer and hugging dimers. The reversible self-assembly behavior can be controlled by tuning solvent, temperature, guest, and H-bond interaction. However, the copillar[5]­arene <b>2a</b> bearing a short 4-hydroxybutyloxy group does not show such a self-assembly behavior to the formation of the self-inclusion monomer and hugging dimers
