Hard Rock Buffet: Chemosynthetic Carbon Use and Environmental Trophic Structuring of Carbonate‐Associated Macrofauna at Southern California Methane Seeps

open access: yesMarine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Diverse invertebrate communities inhabiting carbonate rocks at methane seeps may rely on a mix of local chemosynthetic production and sinking photosynthetic organic matter, with relative importance shaped by environmental conditions. We investigate the contribution of chemosynthetic carbon to macrofaunal diets at six Southern California ...

Angiossarcoma do baço.

open access: yesActa Médica Portuguesa, 1994
Primitive splenic tumors are extremely rare. We report a case, the first at S. José-Hospitais Civis de Lisboa, of a 70 year old woman who presented splenomegaly. She had pelvic irradiation in her past history. MRI revealed a splenic mass characterized as

Synergistic Co‐Doping of Barium and Cobalt Enables Stable and Active RuO2 for Acidic Water Oxidation

open access: yesAngewandte Chemie, Volume 138, Issue 8, 16 February 2026.
Achieving high activity and long‐term durability with non‐iridium catalysts for the acidic oxygen evolution reaction (OER) remains a challenge. This work presents a co‐doping strategy that incorporates Ba and Co into home‐made RuO2, which introduces lattice strain and favorable electronic structure regulation, thereby enhancing both activity and ...

Starting Point, Keys and Milestones of a Computer Code for the Simulation of the Behaviour of a Nuclear Fuel Rod

open access: yesScience and Technology of Nuclear Installations, 2011
The BaCo code (“Barra Combustible”) was developed at the Atomic Energy National Commission of Argentina (CNEA) for the simulation of nuclear fuel rod behaviour under irradiation conditions. We present in this paper a brief description of the code and the

Element Specific Room Temperature Non‐Collinear Magnetism in the M‐Type Hexaferrite SrCo1.2Ti1.2Fe9.6O19${\rm SrCo}_{1.2}{\rm Ti}_{1.2}{\rm Fe}_{9.6}{\rm O}_{19}$

open access: yesAdvanced Physics Research, Volume 5, Issue 2, February 2026.
Non‐collinear magnetism is of high interest in the field of magnetoelectrics supplying a convenient mechanism to break inversion symmetry and thereby allowing for a spontaneous electrical polarization. Such “multiferroics of spin origin” are inherently suitable for electric field control of magnetism, offering a route toward low power ICT applications.

Floristic Diversity of Riparian and Associated Vegetation Along the Amnay River (The Philippines)

open access: yesPlant-Environment Interactions, Volume 7, Issue 1, February 2026.
ABSTRACT Riparian vegetation plays a critical role in maintaining ecological integrity along river corridors, yet it is highly sensitive to changes in hydrological and geomorphic conditions, particularly in sediment‐influenced tropical river systems.
