Fabrication of High‐Density Multimodal Neural Probes Based on Heterogeneously Integrated CMOS

open access: yesAdvanced Science, Volume 13, Issue 34, 19 June 2026.
A chiplet‐based methodology democratizes active neural probe development on standard bulk CMOS services. This yields the first probe combining high‐density electrophysiology (416 electrodes) with calcium imaging (832 photodiodes) and complete on‐chip signal processing across 13 shanks.

Simulation Of Microelectromechanical Systems

open access: yes, 2007
: A method for simulation of microelectromechanical systems is presented. It is based on usage of behavioural simulators and their hardware description languages. Behaviour of a micromachined sensor can be described in such language.

Uranium Doped Gallium Nitride Epitaxial Thin Films

open access: yesAdvanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

Continuation-Based Pull-In and Lift-Off Simulation Algorithms for Microelectromechanical Devices

open access: yes, 2014
The voltages at which microelectromechanical actuators and sensors become unstable, known as pull-in and lift-off voltages, are critical parameters in microelectromechanical systems (MEMS) design.

Microstructured Tactile Sensors With Bismuth Telluride Coatings for Vibration Detection

open access: yesAdvanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
The study reports a high‐performance piezoresistive vibration sensor (PVS) based on a Bi₀.5Sb₁.5Te3 functional layer on a PDMS microstructured substrate. The device exhibits high sensitivity (0.24 kPa−1), fast response, and excellent durability over 10 000 cycles.

Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 3028-3041, June 2026.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

Feasibility of In Vivo Retinal Flavoprotein Autofluorescence Imaging in a Magnetic‐Bead‐Induced Rodent Glaucoma Model

open access: yesJournal of Biophotonics, Volume 19, Issue 6, June 2026.
A scanning laser ophthalmoscope, integrated with a real‐time optical coherence tomography (OCT) alignment monitor, detected flavoprotein fluorescence (FPF) signals associated with mitochondrial dysfunction in a rodent glaucoma model. Under 450‐nm excitation, experimental eyes showed spatially inhomogeneous signals that were absent under 505‐nm ...

Engineering Materials and Interfaces With Plasma‐Enhanced ALD: Toward Energy and Environmental Solutions

open access: yesPlasma Processes and Polymers, Volume 23, Issue 6, June 2026.
This review highlights how plasma‐enhanced atomic layer deposition enables atomic‐scale control of interfacial composition, defects, and energetics. By linking plasma–surface interactions to macroscopic performance, PE‐ALD provides a versatile platform for engineering functional interfaces in photocatalytic, membrane, and energy‐conversion systems ...
