Modulation instability in RF MEMS devices
Analog Integrated Circuits and Signal Processing, 2012 Modulation instability generated by mechanical frequencies in RF MEMS switches is predicted and its potential contribution to the RF signal degradation is discussed. In particular, evaluations have been performed for double clamped configurations in shunt capacitive devices.

International Journal of Cosmetic Science, EarlyView.This study demonstrates that full‐thickness 3D in vitro skin models reliably assess the permeation of cosmetic polyphenols, revealing compound‐specific transport profiles and bridging the gap between conventional cell models and ex vivo human skin, while offering an ethical and robust alternative for dermal absorption screening. Abstract The evaluation

Applied Organometallic Chemistry, Volume 40, Issue 7, July 2026.1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.

HaloTag Fusion Enables Dynamic Analysis of Prion Protein Biosynthesis, Turnover, and Misfolding
ChemBioChem, Volume 27, Issue 11, 15 June 2026.Prion protein (PrP) misfolding underlies fatal neurodegenerative diseases. We developed a HaloTag‐based PrP fusion enabling spatiotemporal labeling of distinct PrP populations in living cells. This system recapitulates native PrP biology, reveals early misfolding events in disease‐associated mutants, and allows mechanistic interrogation of PrP‐lowering

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.Plasma‐sequence‐engineered ALD (PSE‐ALD), based on sequential NH3 and N2 plasma pulses, enables ultrathin, dense SiNx films. ToF‐MS analysis confirms ligand removal via HCl evolution, while increased film density indicates network densification. The resulting SiNx coating provides robust protection of graphite under H2 plasma exposure.

Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio
Advanced Photonics Research, Volume 7, Issue 6, June 2026.This work demonstrates the use of 2D materials drum resonators to generate and modulate radio‐over‐laser signals. Taking advantage of the self‐sustained oscillations arising in cavity optomechanical systems by a continuous wave visible laser, a radio frequency signal is generated and frequency‐modulated by just changing a DC gate voltage.
