A Non‐Reciprocal Architected Porous Medium

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Victims to villains: Internal displacement and nation-building in Ukraine [PDF]

open access: yes, 2017
The war in Donbas has created large-scale displacement within Ukraine, an issue the impoverished state has struggled to manage. Internally displaced people (IDPs) have suffered from prejudice at the hands of host communities and from legal ambiguities ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration

open access: yesAdvanced Materials, EarlyView.
A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

open access: yesAdvanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Hope Groups: a protocol for a cluster randomized controlled trial of psychosocial, mental health, and parenting support groups for Ukrainian caregivers during war and conflict

open access: yesTrials
Background In 2021, more than two-thirds of the world’s children lived in a conflict-affected country. In 2022, 13 million Ukrainians were forced to flee their homes after Russia’s full-scale invasion.

Burden and associated risk factors of undernutrition among displaced pregnant and lactating women: A scoping review

open access: yesGlobal Public Health
Adequate nutrition plays a vital role in maintaining women’s health and ensuring the healthy growth and development of infants and children. However, during emergencies and displacement, multiple factors can disrupt adequate maternal and child nutrition.

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.
