Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Vacancy‐Induced Z‐Contrast Anomaly in Self‐Assembled (Ti,V)O2 Heterostructure

Small, EarlyView.
This study investigates the unexpectedly high contrast observed in ADF‐STEM imaging of spinodal decomposed (Ti,V)O2 heterostructure. In situ heating, GPA, and EELS analyses reveal that oxygen vacancies accumulate in V‐rich layers due to facilitated vacancy migration along [001]R pathways during phase separation by spontaneous ionic diffusion.

Bimetallic Bismuth‐Based Nanoparticles From Pseudo‐Tetrahedral Zintl Anions

Small, EarlyView.
Bismuth‐based Zintl anions are explored as precursors for synthesizing bimetallic nanoparticles with tunable compositions and morphologies, including alloyed, core–shell, and Janus types. The resulting nanoparticles display composition‐dependent UV absorption.

Reductive Transformation of ALD TeO2 into Continuous and Impurity‐Free Tellurium Films

Small, EarlyView.
Atomic layer deposition forms a conformal TeO2 template that transforms to elemental Te through TeH2 mediated reduction using Te(SiMe3)2 and NH3. The transformation is self‐limiting and yields continuous crystalline Te with oxygen‐free bulk and interface even at ultrathin thicknesses.

Long‐term effects of a peer‐led Brief Alcohol Screening and Intervention for College Students (BASICS) intervention to reduce alcohol consumption among Spanish university students: A 12‐month randomised controlled trial

Addiction, EarlyView.
Abstract Background and aims Harmful alcohol consumption remains widespread among university students and is associated with numerous academic, social and health‐related consequences. Peer‐led approaches offer a promising strategy to reduce risky drinking in this population.

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Erratic behavior of platinum-group elements along an olivine–Cr-spinel cotectic in sulfide-undersaturated basaltic magma: roles of Cr-spinel and alloys

Scientific Reports
The behavior of platinum-group elements (PGE) in sulfide-undersaturated primitive magmas may be controlled by crystallization of either Cr-spinel, platinum-group minerals (PGM) or olivine.

Deposition of platinum-group metals in sediment and water bodies along the coastal belt of Ghana [PDF]

Maejo International Journal of Science and Technology, 2011
Water and sediment samples from seven water bodies along the coastal belt of Ghana were assessed for the deposition of platinum-group metals (PGM), i.e. platinum, palladium and rhodium.

Statistical Denoising of Transient Rendering

Computer Graphics Forum, EarlyView.
Abstract Transient rendering simulates light in motion, measuring the time of flight from the light source to the camera. However, the stochastic nature of Monte Carlo is aggravated in transient rendering, since samples are now spread along the temporal domain.
