Advanced Science, EarlyView.We developed a macrophage‐based therapeutic platform, termed trackable tolerogenic macrophages (TTM), for dual‐function immunomodulation and visualization in vivo. TTM cells were engineered to overexpress PD‐L1, incorporate bioorthogonal cell surface tags, and load rapamycin for sustained release.

Cascaded Multilevel Inverter with Less Switches
IOSR Journal of Electrical and Electronics Engineering, 2014 The Inverter translates the power from DC to AC. A Multilevel Inverter is a power electronic device that is used for high voltage and high power applications. The level of the needed input voltage depends entirely on the design and purpose of the inverter. This paper proposes a new topology of a cascaded multilevel inverter that utilizes less number of

Advanced Science, EarlyView.We demonstrate a hybrid WS2/CuInP2S6/graphene heterostructure integrated on a silicon nitride microring resonator for non‐volatile optical phase modulation with ultra‐low energy consumption and low insertion loss. While CIPS alone does not provide efficient optical index modulation, the engineered proposed device structure converts ferroelctric domain ...
