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.

Combustion and propulsive characteristics of potential hybrid rocket propellant

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Presently, the advancements in the field of rockets and rocket propulsion has been done to such an extent where the mission success rate is surely more than its failure. This has also led to a need for much better efficient materials (propellants) that form a major part of the rockets.

Developing Workforce Capability in the Context of HR Ecosystem Learning

Human Resource Management Journal, EarlyView.
ABSTRACT For many organizations, developing workforce capabilities is central as it involves refining critical human resource processes such as upskilling or the acquisition of new profiles. These processes are becoming increasingly complex to manage as organizations collaborate within larger work ecosystems. Surprisingly, little research has addressed

Narrative reconstruction of the self: Living funerals as rituals of trauma and transformation

The Australian Journal of Anthropology, EarlyView.
Abstract Living funerals mark a radical reconfiguration of contemporary engagements with mortality, transforming death from an imposed ending into an actively authored narrative. This study examines the practice in Hong Kong's hybrid sociocultural landscape, where traditional Chinese death rituals collide with neoliberal selfhood and globalised ...

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, Volume 46, Issue 6, Page 1987-2002, June 2026.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Synergistic Engineering of Local Coordination and Electronic Modulation by CoSx Nanoparticles Dictates the Oxygen Reduction Pathway of Cobalt Single‐Atom Catalysts in Acidic Media

Carbon Neutralization, Volume 5, Issue 3, May 2026.
An electron structure modulation engineering strategy is developed by tuning the first coordination shell and leveraging synergistic effects with adjacent nanoparticles of Co single atoms. The CoS@Co–N2S2 catalyst achieves an average H2O2 selectivity of 88% (0.3–0.55 V), whereas CoS2@Co–NS3 exhibits 52% 4e− selectivity.
