Abstract Fe 3 O 4 nanocrystals confined in mesocellular carbon foam (MSU‐F‐C) are synthesized by a “ host–guest ” approach and tested as an anode material for lithium‐ion batteries (LIBs). Briefly, an iron oxide precursor, Fe(NO 3 ) 3 ·9H 2 O, is impregnated in MSU‐F‐C having uniform cellular pores ∼30 nm in diameter, followed by heat‐treatment at 400 °C for 4 h under Ar. Magnetite Fe 3 O 4 nanocrystals with sizes between 13–27 nm are then successfully fabricated inside the pores of the MSU‐F‐C
Abstract A mesostructured spinel Li 4 Ti 5 O 12 (LTO)‐carbon nanocomposite (denoted as Meso‐LTO‐C) with large (>15 nm) and uniform pores is simply synthesized via block copolymer self‐assembly. Exceptionally high rate capability is then demonstrated for Li‐ion battery (LIB) negative electrodes. Polyisoprene‐ block ‐poly(ethylene oxide) (PI‐ b ‐PEO) with a sp 2 ‐hybridized carbon‐containing hydrophobic block is employed as a structure‐directing agent. Then the assembled composite material is c
Abstract We introduce a nanoporous membrane suitable for virus filtration with good dimensional stability under high pressures maintaining high selectivity. The membrane consists of a double layer: The upper layer is a nanoporous film with pore size of ∼17 nm and a thickness of ∼160 nm, which was prepared by polystyrene‐ block ‐poly(methyl methacrylate) copolymer (PS‐ b ‐PMMA) where PMMA block was removed by ultraviolet irradiation followed by rinsing with acetic acid. The nanoporous block copol
Abstract Electronics wastes (e‐wastes) are the major concern in the rapid expansion of smart/wearable/portable electronics in modern high‐tech society. Informal processing and enormous gathering of e‐wastes can lead to adverse human/animal health effects and environmental pollution worldwide. Currently, these issues are a big headache and require the scientific community to develop effective green energy harvesting technologies using biodegradable/biocompatible materials. Piezoelectric/triboelec
Abstract A structured polymer solar cell architecture featuring a large interface between donor and acceptor with connecting paths to the respective electrodes is explored. To this end, poly‐(3‐hexylthiophene) (P3HT) nanorods oriented perpendicularly to indium tin oxide (ITO) glass are fabricated using an anodic aluminum oxide template. It is found that the P3HT chains in bulk films or nanorods are oriented differently; perpendicular or parallel to the ITO substrate, respectively. Such chain ali
Abstract Electric devices has become a necessity in modern smart societies. The energy research community is continually exploring new solutions that can be employed as potential and reliable alternatives to satisfy future energy requirements in this context. Triboelectric/piezoelectric nanogenerators (TNGs/PNGs) are considered promising renewable energy harvesting technologies. TNGs/PNGs are gaining considerable research attention because of their advantages such as ease of fabrication, cost ef
This feature article reviews controlled drug release based on nanoporous membranes for potential medical applications. First, we describe the preparations of nanoporous membranes by top-down and bottom-up methods, and the combination of the two. Then, sustained long-term drug delivery and stimuli-responsive drug delivery by utilizing the nanoporous membranes are explained. The drug delivery system using nanoporous membranes can be used for a new therapy of various diseases through patient-custom
Cylindrical microdomains in thin films of mixtures of polystyrene‐ block ‐ poly(methyl methacrylate) and poly(methyl methacrylate) (PMMA) homopolymer are oriented normal to the film surface (see Figure). Confining the PMMA homopolymer to the microdomains increases the persistence of microdomain orientation over large distances; thus, aspect ratios up to ∼10 are achievable without the use of an external field.
