The uncontrolled treatment process and high concentration of intracellular glutathione compromise the therapeutic efficacies of chemodynamic therapy (CDT). Here, iron oxide nanocrystals embedded in N-doped carbon nanosheets (IONCNs) are designed as a near-infrared light-triggered nanozyme for synergistic cascade tumor therapy. The IONCNs can absorb and convert 980 nm light to local heat, which induces the dissolution of iron oxide for generating Fe 2+ /Fe 3+ in a weak acid environment, apart from thermal ablation of cancer cells. The formed Fe 2+ takes on the active site for the Fenton reaction. The formed Fe 3+ acts as glutathione peroxidase to magnify oxidative stress, improving the antitumor performance. The IONCNs can be used to visually track the treatment process via magnetic resonance imaging. Such IONCNs demonstrate great potential as an exogenously triggered nanozyme via an integrated cascade reaction for imaging-guided synergistic cancer therapy.

A crescente demanda energética mundial e os impactos ambientais acarretados pelo uso de combustíveis fósseis, além da estimativa que aponta para o esgotamento das reservas destes recursos ainda neste século, impulsionam cada vez mais a diversificação da matriz energética. A priorização ao uso de fontes de energia limpa, por exemplo, a partir de recursos renováveis, vem sendo pauta em pesquisas e bibliografias no Brasil e no mundo, e tem enfoque tanto na geração quando no armazenamento de energia. Dispositivos que convertem e armazenam energia, como capacitores e baterias, são fundamentais para a disponibilidade da eletricidade para pronto consumo. Capacidade de armazenamento, tempo de carregamento, segurança operacional, vida útil e custo, são alguns dos aspectos relacionados a tais equipamentos com alta relevância para as presentes e futuras aplicações da transformação tecnológica que já vivenciamos no âmbito da energia. A partir de avanços trazidos pelas novas tecnologias, estudos posteriores têm possibilitado a implementação de melhorias também em baterias já conhecidas. Caso como o das baterias Fe- Ni, que apesar de serem produzidas desde o fim do século XIX, caíram em desuso com o surgimento de materiais mais modernos, e nos últimos anos tiveram um renovado interesse como tópico em pesquisas para melhoria dos parâmetros técnicos e aumento de capacidade e eficiência energética. Este trabalho tem como intuito apresentar os recentes avanços aplicados nos métodos de fabricação, e na composição dos materiais e aditivos para os eletrodos e eletrólitos nas baterias Fe-Ni.

Typical marine vehicles either use diesel or diesel-electric power, which produces toxic pollutants that impact the health of those who live near the harbour. The use of the Battery-operated Electric Propulsion (pure-electric) technology would decrease hazardous pollutants emitted by sea vehicles to zero. Concerns over critical environmental degradation and fossil fuel usage have captivated the automotive market, particularly in maritime vessels, in recent times. The oscillations generated by strong dynamic loads serve as an additional difficulty in ships. To improve stability in shipboard power systems, many generators are now maintained online at far lower than their efficient point. So, to increase the fuel mileage of shipboard power systems, a simple option, a compromise between fuel savings and durability, might be presumed: minimal generator operation with ensured safety. In contrast to previous systems in which propulsion and service loads are powered by distinct generators, propulsion and service loads are linked into a shared network in pure-electric ships to achieve reduced fuel economy with lower emissions. Integration of an energy storage system (ESS) is said to be a useful strategy for increasing the reliability of the shipboard power system. Batteries, ultra-capacitors, flywheels, and fuel cells are examples of energy storage technologies that are now employed in a variety of applications. Marine batteries are particularly developed for sea transport, having larger plates and more resilient structure to handle the stress and hammering that might arise on any powerboat. These batteries have been designed specifically to suit the prospective and future demands of marine transportation applications. This study examines many types of maritime energy storage devices that have been widely employed to enhance the overall efficiency of sea transport.
