Exploring the Diversity of Faint Satellites in the M81 Group

The Astrophysical Journal
In the last decade, we have been able to probe further down the galaxy luminosity function than ever before and expand into the regime of ultra-faint dwarfs (UFDs), which are some of the best probes we have of small-scale cosmology and galaxy formation ...

Maillard Type Reaction for Electroless Copper Plating onto Ceramic Nanoparticles

Advanced Engineering Materials, EarlyView.
This work presents the manufacturing of copper‐plated ceramic nanoparticles in an environmentally friendly way. Supported by organic functionalizations with pectin an electroless plating step can be performed. Sustainable reagents like xylose, and several amino acids are used for the reduction process.

Improvement of 3D Power Line Extraction from Multiple Low-Cost UAV Imagery Using Wavelet Analysis

Sensors, 2019
Three-dimensional (3D) mapping of power lines is very important for power line inspection. Many remotely-sensed data products like light detection and ranging (LiDAR) have been already studied for power line surveys. More and more data are being obtained

Icephobic Gradient Polymer Coatings Coupled with Electromechanical De‐icing Systems: A Promising Ice Repellent Hybrid System

Advanced Engineering Materials, EarlyView.
A hybrid system for de‐icing made of gradient polymer coatings, deposited on aluminum coupled with an electromechanical system, is demonstrated as an effective and durable strategy for reducing drastically ice adhesion. The system is capable of detaching ice blocks over the coating in less than 1 s, regardless of the ice type and covered area ...

The MBH–M∗ Relation up to z ∼ 2 through Decomposition of COSMOS-Web NIRCam Images

The Astrophysical Journal
Our knowledge of relations between supermassive black holes and their host galaxies at z  ≳ 1 is still limited, even though being actively sought out to z  ∼ 6.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?

Advanced Engineering Materials, EarlyView.
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

The TRGB–SBF Project. II. Resolving the Virgo Cluster with JWST

The Astrophysical Journal
The Virgo Cluster is the nearest substantial cluster of galaxies to the Milky Way and a cornerstone of the extragalactic distance scale. Here, we present JWST/NIRCam observations that simultaneously cover the cores and halos of 10 galaxies in and around ...

Partitioning and Coarsening Dynamics of Precipitate‐Strengthened Cr‐Si Alloys: The Role of Ge, Pt, and Mo

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.

All Puffed Up: Exploring Ultra-diffuse Galaxy Origins Through Galaxy Interactions

The Astronomical Journal
We present new follow-up observations of two ultra-diffuse galaxies (UDGs) selected for their distorted morphologies and tidal features, suggestive of tidal influence.

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves

Advanced Engineering Materials, EarlyView.
Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.
