Proceedings of the American Mathematical Society, 1981 This result remains true in some measure spaces, which have a base, whose cardinal has measure zero [5, p. 64]. By means of the abstract Baire category theory, which was developed in [2-4], we present in this note a new, quite different generalization of Theorem 1.

Mesoporous Silica Microspheres by Super‐Fast Alkaline Etching of Micrometer‐Sized Stöber Particles
Advanced Engineering Materials, EarlyView.Microscale silica particles are prepared along with a modified, scalable Stöber synthesis using the continuous addition of tetraethoxy silane to an ethanolic solution of ammonia with KCl. Etching with hydroxide ions at 95 °C gave porous analogs within minutes. Monodisperse particles are isolable in high yield after precipitation in ethanol.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior
Advanced Engineering Materials, EarlyView.Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...

Advanced Engineering Materials, EarlyView.Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.

Journal of Mathematical Analysis and Applications, 1990 AbstractIn the paper we extend the Hopf decomposition to positive operators in Banach lattices. Let E be a Banach lattice, let E′ be the dual of E, let T: E → E be a positive operator, and let T′ be the dual of T. We define two conservative ideals IC, BC in E, E′, respectively, and two dissipative ideals ID, BD in E, E′, respectively.

Advanced Engineering Materials, EarlyView.The utilization of direct energy deposition (DED)‐arc additive manufacturing processes in industrial applications is increasing, and these processes have the potential for multi‐material applications. This work provides a overview of the state of research in DED‐arc made functional graded structures, to establish a link to potential industrial ...

Toughness of Confined Auxetic Foams
Advanced Engineering Materials, EarlyView.Auxetic (negative Poisson's ratio) materials offer benefits such as impact mitigation, thermal insulation, vibration damping, and reduced shear strain, although their fracture mechanics are largely unexplored. This study investigates damage initiation and propagation in confined re‐entrant auxetic foams from polyurethane via experimental ...
