Plasmonic CO2 methanation using γ-Al2O3-supported Ru nanorods was carried out under continuous-flow conditions without conventional heating, mildly concentrated sunlight as the sole and sustainable energy source (AM 1.5, irradiance 5.5–14.4 kW·m−2 = suns). Under 12.5 suns, a conversion exceeding 97% achieved with complete selectivity towards CH4 stable production rate (261.9 mmol·gRu−1·h−1) for...

postcolonial feminism is an exploration into the interactions of colonialism with gender, nation, class, race, and sexualities in different contexts of women’s lives. postcolonial feminism or the ‘third world feminism’ originated as a critique of mainstreams in the western feminist theorists, investigating the portrayal of women in the literature and society of the colonized countries as margin...

The present paper is concerned with the problem of weighted best simultaneous approximations in Banach spaces. The weighted best simultaneous approximations to sequences from Sand BS-suns in the Banach space are characterized in view of the Kolmogorov conditions. Applications are provided for weighted best simultaneous approximations from RS-sets and strict RS-sets. Our results obtained in the ...

The topic of Hamiltonian chaos is a whole course in itself, and we will only touch on a few highlights. For further information see Ott chapter 7, and review papers by Berry [1] and Helleman [2]. The ideal pendulum discussed in chapter 2 is an example of a Hamiltonian system. In many ways this system is typical of the ones taught in elementary courses on mechanics: the orbits are periodic and c...
