Tuning Stability and Optoelectronic Properties of CsSnI3 Via Rare‐Earth Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sn‐based halide perovskites are promising optoelectronic materials but are limited by poor stability. Thus, rare‐earth elements (RE) doping in CsSnI3 addresses this limitation, significantly enhancing thermodynamic, mechanical, and chemical stability, while simultaneously tuning electronic characteristics and modulating optical responses in the ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Semiprimitive groups - a classification theorem (sort of)

open access: yes, 2017
A transitive permutation group is called semiprimitive if each normal subgroup is transitive or semiregular. This large class of groups includes the classes of primitive, quasiprimitive, innately transitive and Frobenius groups.

Dignity's Dilemma: Categorical Objections to Autonomous Weapons and Their Pacifist Entailments

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Dignity objections to autonomous weapon systems are prominent in contemporary military ethics, yet their theoretical foundations remain underexamined. This article reconstructs those foundations, showing what categorical dignity objections require to function as absolute prohibitions.

Adaptive Immunity in Marsupials

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.
