Extraction replica method from thinned transmission electron microscopy samples without floating off carbon films: A case study on reduced activation steel

Journal of Microscopy, Volume 303, Issue 1, Page 88-100, July 2026.
Abstract A recipe for producing carbon extraction replicas from twin‐jet electropolished disks is described. This technique allows tracking the analysed region with respect to the bulk sample. An example use of the method as applied to a reduced activation ferritic martensitic (RAFM) steel, ‘UK‐RAFM’, is reported.

Retinoic Acid Informs the Positional Identity of Frontonasal Neural Crest Cells Through Alx Family of Transcription Factors

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Retinoic acid (RA) regulates the positional identity of cranial neural crest cells (CNCCs) through the transcription factors Alx1 and Alx4. Upon receiving RA from the local environment, liganded RAR/RXR heterodimers activate the expression of Alx1 and Alx4, which promote the frontonasal identity of CNCCs and inhibit the first pharyngeal arch identity ...

Photonic Properties of InAs Quantum Dots by Post‐Growth Maskless Site‐Selective Focused Ion Beam Implantation

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
A low‐energy focused ion beam process achieves localized spectral modification of InAs quantum dots. By leveraging low ion straggle and a compact damage volume, this methodology offers unique spatial control and accuracy. This maskless approach provides a scalable platform for site‐selective engineering for advanced photonic integrated circuits and ...

Mimicking a Light‐Harvesting Complex to Accelerate Photooxidation in Asymmetric Lipid Membrane Nanoreactors

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
Biomimetic liposome nanoreactors mimicking natural light‐harvesting complexes enable efficient photooxidation of NADH. Membrane‐anchored fluorescein transfers energy via FRET to membrane anchored eosin Y, oxidizing NADH. While symmetric membranes show little improvement, asymmetric chromophore distribution enhances photooxidation rates by up to 27 ...

UVIT/AstroSat studies of blue straggler stars and post-mass transfer systems in star clusters: detection of one more blue lurker in M67 [PDF]

Journal of Astrophysics and Astronomy, 2020
The blue straggler stars (BSSs) are main-sequence (MS) stars, which have evaded stellar evolution by acquiring mass while on the MS. The detection of extremely low mass (ELM) white dwarf (WD) companions to two BSSs and one yellow straggler star (YSS ...
