Plasmonic Horizon in Gold Nanosponges
Nano Letters, 2018An electromagnetic wave impinging on a gold nanosponge coherently excites many electromagnetic hot-spots inside the nanosponge, yielding a polarization-dependent scattering spectrum. In contrast, a hole, recombining with an electron, can locally excite plasmonic hot-spots only within a horizon given by the lifetime of localized plasmons and the speed ...

Nanosponges for water purification
Clean Products and Processes, 2000We synthesized a new class of organic nanoporous polymers using cyclodextrins as basic building blocks. These processible nanoporous polymers were named 'nanosponges' because they have nanometer-size pores (distribution 0.7–1.2 nm) and exhibit superior ability to absorb organic molecules in water. Cyclodextrin cavities provide a hydrophobic environment

Angewandte Chemie International Edition, 2007
Semiconducting metal oxides are widely considered as the most promising platform for solid-state gas sensors. Due to enhanced responsiveness of conductance to surface effects in low dimensional nanostructures, various forms of nanostructured metal oxides have been synthesized and their sensing properties studied.

Soluble Intramolecularly Hypercrosslinked Nanosponges
2011Publisher Summary This chapter introduces a novel macromolecular species, the intramolecularly hypercrosslinked polystyrene (IHPS) or “nanosponge” that differs fundamentally from the four basic types: (1) globular macromolecules, (2) rigid rod-like molecules, (3) flexible and voluminous coils, (4) highly branched (hyperbranched) macromolecules with ...

Nanosponges for hydrogen storage
Journal of Materials Chemistry, 2012Hydrogen storage by physisorption is a very promising technique due to its fast kinetics and full reversibility. The key to reach high storage capacities is high specific surface area. Extremely large surface areas can only be achieved by materials with high porosity, i.e., nanosponges like MOF-177 (4239 m2 g−1) and DUT-23(Co) (4850 m2 g−1).

Nanosponge formulations as oxygen delivery systems
International Journal of Pharmaceutics, 2010Three types of cyclodextrin nanosponges were synthetized cross-linking α, β or γ cyclodextrin with carbonyldiimidazole as cross-linker. Nanosponges are solid nanoparticles previously used as drug carriers. In this studies cyclodextrin nanosponges were developed as oxygen delivery system.

Nanosponges for Carbon Dioxide Sequestration
2019The causes of global warming have been subject of controversy, especially in the last 50–100 years. There has been a remarkable effort by the international scientific community to reduce the amounts of CO2 emitted into the atmosphere. It is well known that the CO2 capture step accounts for around 60–70% of the whole cost of the carbon capture and ...
