Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

The Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Risk‐aware safe reinforcement learning for control of stochastic linear systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Engineering Spin State of Ni Single‐Atoms to Enhance Electrocatalytic Activity of Sulfur Conversion in Lithium–Sulfur Batteries

Carbon Energy, EarlyView.
Ni SACs with high‐spin state show strong catalytic activity toward lithium polysulfides (LPSs), whereas the Ni SACs with low‐spin state have strong adsorption capacity for LPSs. Therefore, the preparation of Ni SACs with an intermediate spin state by controlling pyridinic N and pyrrolic N enables an excellent balance between the adsorption and ...

Beyond Activity: The Unified Framework of the Sabatier Principle to Guide Rational Design of Durable and Active Electrocatalysts

Carbon Energy, EarlyView.
In this review, a unified framework of the Sabatier principle is applied to a diverse range of catalytic and electrocatalytic systems for advanced clean energy technologies, with a particular focus on the oxygen reduction reaction (ORR). This approach will guide the design and development of highly active and stable catalysts for fuel cells ...

(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3

Chemistry – A European Journal, EarlyView.
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.
