Tracking the uptake of nanomaterials by living cells is an important component in assessing both potential toxicity and in designing future materials for use in vivo. We show that the difference in the local elasticity at the site of silica SiO2 nanoparticles confined within a macrophage enables functional ultrasonic interactions. By elastically exciting the cell, a phase perturbation caused by...

Correction for 'Phase behavior of colloid-polymer depletion mixtures with unary or binary depletants' by Nayoung Park et al., Soft Matter, 2017, 13, 2781-2792.

Space-time coding has shown great promise for digital transmission in wireless communication links, especially when the channel response is known at the receiver. Space time coding combined with continuous phase modulation (CPM) can offer better tradeoffs in bandwidth and power efficiency. Because of the memory inherent in CPM, channel estimation is often harder than for linear modulations. In ...

Phase-matched harmonic conversion of visible laser light into soft x-rays was demonstrated. The recently developed technique of guided-wave frequency conversion was used to upshift light from 800 nanometers to the range from 17 to 32 nanometers. This process increased the coherent x-ray output by factors of 10(2) to 10(3) compared to the non-phase-matched case. This source uses a small-scale (s...

Using event-driven molecular dynamics simulations, we study a three-dimensional one-component system of spherical particles interacting via a discontinuous potential combining a repulsive square soft core and an attractive square well. In the case of a narrow attractive well, it has been shown that this potential has two metastable gas-liquid critical points. Here we systematically investigate ...

A zero-voltage transition (ZVT) soft-switching inverter for an induction motor drive is developed. The proposed soft-switchng inverter is formed from the traditional pulse-wi dth modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is acheved through applying PWM switching control signals with suitable delays for the main and auxiliary switches....
