Exploiting CO2‐Derived Carbon in Lithium‐Ion Batteries
Advanced Energy and Sustainability Research, EarlyView.In this work, a carbon nanomaterial (CNM) extracted from CO2 reduction treatment is used as the conductive additive in lithium‐ion battery graphite anodes and LiFePO4 cathodes. The electrodes are produced by casting, using both sodium alginate as a green, water‐soluble, alternative binder.

Semiclassical Theory of Short Periodic Orbits in Quantum Chaos [PDF]
, 1999 We have developed a semiclassical theory of short periodic orbits to obtain all quantum information of a bounded chaotic Hamiltonian system. If T_1 is the period of the shortest periodic orbit, T_2 the period of the next one and so on, the number N_p.o.

Semiclassical quantization with short periodic orbits [PDF]
, 1999 We apply a recently developed semiclassical theory of short peridic orbits to the stadium billiard. We give explicit expresions for the resonances of periodic orbits and for the application of the semiclassical Hamiltonian operator to them. Then, by using the 3 shortest periodic orbits and 2 more living in the bouncing ball region, we obtain the first ...

Business Strategy and the Environment, EarlyView.ABSTRACT Modern society grapples with socio‐environmental challenges such as pandemics, climate change, resource depletion, and poverty alleviation. Recent research underscores the crucial role of intermediaries in expediting the shift towards sustainability management. This study examines how intermediaries influence sociotechnical transitions towards

Adsorption of $^4$He on a single C$_{60}$ [PDF]
, 2003 The adsorption of $^4$He inside and outside a single fullerene C$_{60}$ is studied. A physisorption potential is proposed. The energetics and structural features of C$_{60}$-$^4$He$_N$ clusters are investigated. Particular attention is paid to the growth of the highly pronounced layered density profile.

Desempenho de um sistema de bombeamento fotovoltaico na região oeste do Paraná
Revista Agrogeoambiental, 2010 Os sistemas convencionais de fornecimento de energia elétrica nem sempre constituem a melhor opção para satisfazer as demandas do setor rural, por isso existe uma constante necessidade de se pesquisar sobre a utilização de fontes alternativas de energia.

The $Λ_0$ Polarization and the Recombination Mechanism [PDF]
, 1997 We use the recombination and the Thomas Precession Model to obtain a prediction for the $\Lambda _0$ polarization in the $p+p \to \Lambda_0+X$ reaction. We study the effect of the recombination function on the $\Lambda_0$ polarization.

SISTEMAS RESIDENCIAIS DE ENERGIA SOLAR FOTOVOLTAICA
, 2022 O Sol é uma fonte inesgotável de dois tipos de energia: fotovoltaica e térmica. A energia fotovoltaica refere-se a conversão da radiação solar em energia elétrica. Para tanto, utiliza geradores de energia solar que são formados por quatro componentes básicos: módulos fotovoltaicos, responsáveis pela transformação da energia solar em energia elétrica ...
