“…To achieve structures far below 1 mm, we identied extreme ultraviolet interference lithography (EUV-IL) to be an ideally suited method for this purpose. Also laser interference lithography (LIL), as well as EBL, 26 were considered as generally suitable techniques. However, compared to LIL, EUV-IL has the advantage that resolutions far below 100 nm can be achieved.…”

We present a versatile strategy toward the preparation of nanostructured metal sulfide layers, which exploits the photosensitivity of metal xanthates as a powerful tool for lithographic structuring. Using extreme ultraviolet interference lithography (EUV-IL), we successfully realized well-defined column and comb nanostructures. This approach provides new pathways to fabricate highly ordered structured metal sulfide layers with periodicities far below 100 nm for potential application in hybrid solar cells. © 2013 The Royal Society of Chemistry

“…In particular, the increase of the overall viscosity, the delayed thermomechanical response, and the control on the dispersion uniformity may strongly limit the possibility of shaping composites in the form of nanostructures or wires, which would benefit of an enhanced surface active area and additional possibilities of device design. In this respect, the implementation of low‐temperature methods for the in situ synthesis of BaTiO 3 NPs into a preformed polymer matrix, analogously to previous studies on light emissive nanocrystals, is especially interesting in view of realizing energy harvesting composites. Also, graphene and its derivatives have recently emerged as alternative fillers for PVDF .…”

Technologies for energy harvesting from objects in motion are gaining a continuously increasing interest to directly power wearable electronics, sensors, and wireless transmitters. New networks where things will be uniquely identified and interconnected will require key enabling technologies, particularly cheap, flexible generators of renewable energy, conformable to any solid surface, to power independently individual objects and data transmission. Polymer-based nanogenerators (PNGs), capable of converting mechanical energy into electricity, have exact features to fulfill these requirements. This article highlights advances in PNGs with focus on material chemistries and geometrical features, device design strategies, and performances. Representative examples of applications which show large-scale capability are reported. Concluding sections summarize the key challenges and the commercialization perspectives of PNGs for use in real life applications.

“…In this way, nanocomposite fibers are electrospun with absorption and emission in the visible and near infrared spectral range, by using inorganic NPs (i.e., metallic, such as Ag, Au, Pd and Pt, with size‐tunable absorption, or semiconducting from II–VI or III–V elements, with size‐tunable electronic band gap and emission bands) . Optically active nanocrystals are embedded in electrospun NFs by two methods: mixing ex situ colloidal particles with the organic solution, or synthesis in situ following the embedment of suitable molecular precursors in the fibers and decomposition by thermal treatment, optical or electron‐beam exposure, and gas reaction . The first method generally allows for more precisely controlling the size distribution of particles, and, consequently their optical bands .…”

Chemical sensors have been essential components in recent years due to the gathering attention in environmental monitoring and healthcare. In this review, the authors comprehensively highlight recent progresses on the 1D chemiresistive-type sensors based on semiconductor metal oxides (SMOs) and optical-type sensors, which are prepared by electrospinning technique. In the part of chemiresistive-type sensors, diverse synthesis techniques for 1D SMO nanofibrous structure are presented with controlled microstructure and surface morphology. In addition, unique functionalization routes of emerging nanocatalysts encapsulated by bio-inspired templates are described for the next generation catalyst on the 1D SMO nanofibers (NFs). For the optical-type sensors, new classes of 1D NFs employing specific absorption and emission properties are introduced. In particular, diverse 1D NF-based colorimetric and fluorescence sensors as well as Raman and surface-enhanced Raman scattering sensors are covered in the view point of material preparation and optical sensing properties. Finally, the authors prospect future research directions to overcome current limitations and challenges to achieve high performance chemical sensors.
