On the Relationship between Corneal Biomechanics, Macrostructure, and Optical Properties

Journal of Imaging, 2021
Optical properties of the cornea are responsible for correct vision; the ultrastructure allows optical transparency, and the biomechanical properties govern the shape, elasticity, or stiffness of the cornea, affecting ocular integrity and intraocular ...

A Borane Sandwich Analogue of Ferrocene

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
The first ferrocene analogue with two boron‐based ligands is identified through a global exploration of the FeB10H20 potential energy surface. The η5,η5‐Fe(B5H10)2 complex emerges as the global minimum, showing that metal coordination inverts borane stability and enables aromatic boron rings inaccessible in isolation.

Antifouling capacity of substrate materials and their effects on settlement and post‐settlement survival of Acropora palmata and Orbicella faveolata

Restoration Ecology, EarlyView.
Abstract Introduction In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, post‐settlement survival remains a major bottleneck, as spat are particularly vulnerable to competition with fouling organisms.

Experimental Study on the Time Response of the Microstructure of a Bentonite Suspension

Fluids
To obtain deeper information on the role played by microstructure evolution with time of particle suspensions specifically used in drilling processes, two representative time scales of a bentonite suspension were proposed. On one hand, a thixotropic time,

Rational Design of Multifunctional Tacrine Derivatives as Candidates for the Treatment of Alzheimer and Parkinson Diseases

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
We present a set of multifunctional tacrine derivatives, designed with the CADMA‐Chem protocol, aimed for Alzheimer and Parkinson diseases. Of the tacrines designed, TAC‐674 and TAC‐678 are the best candidates to act as multifunctional antioxidants and neuroprotectors for Alzheimer and Parkinson diseases, respectively.

Shannon Entropy and Lévy Statistics for Machine Learning‐Assisted Spectral Sensing in Random Fiber Lasers With Magnetic Core–Shell Nanoscatterers

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Random laser emission was observed in a polymer optical fiber structure doped with magnetic Fe3O4@SiO2 core–shell nanoparticles. A direct relationship was demonstrated between Shannon entropy and Lévy statistics regarding intensity fluctuations in the emission modes. The analysis indicated a potential application in a proposed magnetic field and energy

Temperature dependence of ferromagnetic resonance measurements in nanostructured line arrays

EPJ Web of Conferences, 2014
We report the effect of temperature on the ferromagnetic resonance (FMR) spectra of nanostructured line arrays. Different temperature dependences are observed for permalloy an nickel based samples.
