Mapping of Physiological Signals From Wireless Battery‐Free Implants With Plane‐Wave Ultrasound Imaging

open access: yesAdvanced Materials Technologies, EarlyView.
Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.

Could Edible Photonic Structures Be an Alternative to Traditional Food Coloring?

open access: yesAdvanced Optical Materials, EarlyView.
What if color in food came from photonic structures? This perspective introduces structural color as a potential next‐generation solution to replace conventional colorants in foods. It discusses edible photonic materials, their unique benefits, and the technological, safety, and consumer acceptance challenges that must be addressed to bring this ...

A neomorphic cancer cell-specific role of MAGE-A4 in trans-lesion synthesis

open access: yesNature Communications, 2016
Trans-lesion synthesis (TLS) is an important DNA-damage tolerance mechanism that permits ongoing DNA synthesis in cells harbouring damaged genomes. The E3 ubiquitin ligase RAD18 activates TLS by promoting recruitment of Y-family DNA polymerases to sites ...

Impact of grain evolution on the chemical structure of protoplanetary disks

open access: yes, 2010
We study the impact of dust evolution in a protoplanetary disk around a T Tauri star on the disk chemical composition. For the first time we utilize a comprehensive model of dust evolution which includes growth, fragmentation and sedimentation.

Photonics of Topological Magnetic Textures

open access: yesAdvanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Contribution of CFTR to Alveolar Fluid Clearance by Lipoxin A4 via PI3K/Akt Pathway in LPS-Induced Acute Lung Injury

open access: yesMediators of Inflammation, 2013
The lipoxins are the first proresolution mediators to be recognized and described as the endogenous “braking signals” for inflammation. We evaluated the anti-inflammatory and proresolution bioactions of lipoxin A4 in our lipopolysaccharide (LPS-)induced ...

Polarization‐Sensitive Au‐TiO2 Nanopillars for Tailored Plasmonic Enhanced Light‐Driven Reaction Activity

open access: yesAdvanced Optical Materials, EarlyView.
Manipulating the product generation yield is achieved on a model plasmonic resonance‐driven reaction by tuning the nonthermal effects of localized surface plasmonic resonance on an elliptical Au‐TiO2 nanopillar metasurface. Asymmetric configuration of the elliptical nanopillar array governs the polarization‐dependent optical properties redshifting the ...
