In this article, we are presenting an original selective plane illumination fluorescence microscope dedicated to image "Organ-on-chip"-like biostructures in microfluidic chips. In order to be able to morphologically analyze volumetric samples in development at the cellular scale inside microfluidic chambers, the setup presents a compromise between relatively large field of view (∼ 200 µm) and moderate resolution (∼ 5 µm). The microscope is based on a simple design, built around the chip and its microfluidic environment to allow 3D imaging inside the chip. In particular, the sample remains horizontally avoiding to disturb the fluidics phenomena. The experimental setup, its optical characterization and the first volumetric images are reported.

Hyperdivergent skeletal Class II malocclusion is largely genetically determined and poses significant challenges in orthodontic treatment, particularly due to compromised facial aesthetics, reduced bite force and airway narrowing. Traditionally, orthognathic surgery has been the standard treatment for correcting such skeletal discrepancies. However, the advent of temporary skeletal anchorage devices (TSADs) has expanded the possibilities for orthodontic camouflage by allowing effective vertical control.

The nominally trigonal, pseudo-Jahn-Teller (PJT)-active, = 1/2 N-bound complexes, , M = Fe, Co, with three in-plane phosphine ligands and axial donors, E = Si, B, C, include functional nitrogenase models that catalyze the reduction of N to NH. We applied EPR, P ENDOR spectroscopy, and DFT computations to characterize the PJT-induced distortions of four selected , revealing how the metal ion and axial ligand E together tune both PJT dynamics, as revealed by P ENDOR and N activation, as indicated by a decrease in N≡N stretching frequency, ν(N≡N). , and each exhibit a single P isotropic hyperfine coupling, revealing dynamic pseudorotation of the PJT distortion, producing averaged symmetry with equivalent phosphine ligands.

With the increasing complexity of treatment plans and the implementation of adaptive therapy, the need for efficient alternatives is pressing. Simulation-based techniques are proposed as a replacement or enhancement for experimental ones.

Electrochemical CO reduction (COR) with transition-metal catalysts often suffers from low selectivity for value-added products. Organic layers have been explored to enhance selectivity by modifying local environments and adjusting the CO and CO adsorption, but their role remains unclear due to structural and mechanical instability. Here, we designed a well-defined organic layer model consisting of ∼4 nm-thick covalent organic framework (COF) films with ∼3 nm pores and a cm-scale area.

Neuromorphic computing presents a promising solution for the von Neumann bottleneck, enabling energy-efficient and intelligent sensing platforms. Although 2D materials are ideal for bioinspired neuromorphic devices, achieving multifunctional synaptic operations with simple configurations and linear weight updates remains challenging. Inspired by biological axons, the in-plane anisotropy of 2D NbGeTe is exploited to develop dual electronic-optical synaptic devices.
