LIBS Elemental Mapping of a Feldspathic Lunar Meteorite: Insights for In Situ Exploration

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract To meet the objectives of the many robotic and human missions planned for the Moon in the coming decade, new scientific instruments are currently under development. Laser‐induced breakdown spectroscopy (LIBS) is a robust technique for quantifying elemental abundances by focusing a pulsed laser to generate a plasma and collecting its emission ...

Characterization and Design Framework for Micro‐ and Nanoscale Printed Metal Interconnects in Hybrid Electronic Systems

Advanced Materials Technologies, Volume 11, Issue 11, 5 June 2026.
This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

Phosphinate or Urea? Synthesis and Biological Evaluation of Prostate Specific Membrane Antigen‐Targeted Fluorophores With Different Zinc‐Binding Motif

ChemMedChem, Volume 21, Issue 10, 27 May 2026.
A comparison of two structurally related prostate specific membrane antigen (PSMA)‐targeted fluorophores revealed that the substitution of the urea motif lysine‐urea‐glutamate (KuE) by a phosphinate leads to probes with low nanomolar PSMA‐affinity, good and specific tumor uptake, and low off‐target tissue retention in mice.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, Volume 13, Issue 30, 28 May 2026.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Pre-engineered abruptly autofocusing beams [PDF]

Optics Letters, 2011
We introduce a new family of (2+1)D light beams with pre-engineered abruptly autofocusing properties. These beams have a circularly symmetric input profile that develops outward of a dark disk and oscillates radially as a sublinear-chirp signal, creating a series of concentric intensity rings with gradually decreasing width.

Controlling the Abrupt Autofocusing of Circular Airy Vortex Beam via Uniaxial Crystal

Photonics, 2022
The propagation of many kinds of structured light beams in uniaxial crystal has been investigated. However, the investigation of the evolution of these structured light beams after the uniaxial crystal is lacking. In this paper, an evolution formula of a
