Thought Experiments and the (Fictional) Exploration of Outer Space

open access: yes
In this chapter, I characterize space exploration as it features in most works of sci-fi, and suggest that such works typically foster imaginings and reflections upon human present and future conditions. By relying on a lively debate in the philosophy of

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

The challenges in drafting national law for space activities: A Brazilian experience

open access: yes, 2014
The international space law regime mandates that individual nation states are both responsible and liable for their respective national space activities. This is one of the most important norms of space law, which face today more than never the challenge

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, Volume 36, Issue 43, 29 May 2026.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

International legal features of commercialization of space activity

open access: yesHalyk̦aralyk̦ k̦atynastar ža̋ne halyk̦aralyk̦ k̦u̇k̦yk̦ seriâsì, 2018
The article is dedicated to the study of the problem of commercialization of space activity in the outer space. The world market of the outer space services has been formed relatively recently, but it is developing very rapidly.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Who will own outer space: governance over space resources in the age of human space exploration

open access: yes, 2011
As humanity plans to expand further into outer space, significant issues related to sovereignty, territory and international law must be addressed. This chapter examines these issues, looking, in particular, at the conceptualisation of outer space as a ...

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, Volume 36, Issue 43, 29 May 2026.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by
