Phakic Intraocular Lenses An Overview
Delhi Journal of Ophthalmology, 2013 Currently, there are four general approaches to correct refractive errors: refractive corneal surgery, crystalline lens surgery, and implantation of an intraocular lens (IOL) in the anterior or posterior chamber.

Advanced Materials, EarlyView.A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Reconstruction of the crystalline lens full-geometry from OCT images acquired with off-axis viewing
Scientific ReportsThe crystalline lens of the eye is an optical structure that, together with the cornea, focuses images onto the retina. In a young and healthy eye, the lens is transparent and adjusts its shape to focus on near and distant objects (accommodation).

Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature
Advanced Materials, EarlyView.We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

Advanced Materials, EarlyView.Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Radiation‐Matter Interaction in Chemical Vapor Deposition‐Grown Two‐Dimensional Tungsten Disulfide
Advanced Materials Interfaces, EarlyView.Gamma irradiation tunes the magnetic properties of CVD‐grown WS2 material. Moderate irradiation doses induce low‐temperature ferromagnetic‐like behavior, whereas higher doses suppress the magnetic response because of increased defect formation. These findings provide insight into defect‐mediated magnetism in 2D TMDs and could be relevant to future ...

Material Before Morphology: Substrate‐Dependent Mechanical Tuning of Radular Teeth
Advanced Materials Interfaces, EarlyView.Substrate‐dependent material tuning in Clausilia radular teeth. Closely related taxa retain a conserved gross tooth morphology, but differ in elemental composition and mechanical properties according to feeding substrate. Rock‐associated taxa show increased Ca–Si enrichment and higher stiffness and hardness, especially in the central radular region ...
