Microsecond X‐ray reflectometry

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1112-1120, August 2026.
X‐ray reflectometry is accelerated to 213 µs net exposure time using galvanometer scanning, which enables unprecedented temporal resolution for studying dynamic thin‐film processes.We accelerate synchrotron X‐ray reflectometry (XRR) by more than an order of magnitude and demonstrate the acquisition of full reflectivity curves within 213 µs over a qz ...

Síndrome de Chandler

open access: yesRevista Cubana de Oftalmología
El síndrome de Chandler es una de las variaciones clínicas del síndrome iridocorneoendotelial, donde el denominador común es una alteración del endotelio corneal cuyo diagnóstico es, en ocasiones, muy difícil de realizar por la complejidad y la ...

A neutron microscope using a nested Wolter‐I condenser and a bank of diffractive–refractive achromatic objectives

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1282-1293, August 2026.
A neutron microscope is presented comprising a Wolter‐I nested mirror optic as condenser and a 2D array of neutron achromats as objective.We present a nested Wolter‐I mirror design for a neutron condenser, which is based on established X‐ray telescope technology.

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1788-1805, August 2026.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

Origin and formation of a chondritic xenolith in Krymka (LL3.2, breccia): Indications for a late formation of the accretionary breccia

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2016-2047, August 2026.
Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.
