Flexible light valves using polymer-dispersed liquid crystals and TiO2/Ag/TiO2 multilayers

The era of flexible optoelectronics demands development of wearable and bendable structures, foldable touch screens, paper-like displays, and curved and flexible solid-state lighting devices. Here, we demonstrate the fabrication of highly flexible light valves using polymer-dispersed liquid crystal (PDLC) and TiO2/Ag/TiO2 transparent conductive films. TiO2/Ag/TiO2 multilayers were prepared by magnetron sputtering technique on polyethylene terephthalate (PET) substrates at room temperature. By keeping the equivalent TiO2 layers and varying the deposition time of the Ag layer, proper metal nanograins on TiO2 planar plane were formed, providing the best tradeoff between the transmittance, sheet resistance and bending ability. The results are validated by numerical simulations that suggest the best match between the deposition time and individual layer thickness. Based on the performed characteristics of TiO2/Ag/TiO2/PET structures, several flexible light valves are fabricated and characterized. The sheet resistance values of TiO2/Ag/TiO2/PET remain unchanged over 1000 bending cycles. The measured driving voltage and response time values open great potential of TiO2/Ag/TiO2/PET for integration into next-generation ITO-free flexible and stretchable devices.

BackgroundAlthough various machine learning-based predictors have been developed for estimating protein-protein interactions, their performances vary with dataset and species, and are affected by two primary aspects: choice of learning algorithm, and the representation of protein pairs. To improve the performance of predicting protein-protein interactions, we exploit the synergy of multiple learning algorithms, and utilize the expressiveness of different protein-pair features.ResultsWe developed a stacked generalization scheme that integrates five learning algorithms. We also designed three types of protein-pair features based on the physicochemical properties of amino acids, gene ontology annotations, and interaction network topologies. When tested on 19 published datasets collected from eight species, the proposed approach achieved a significantly higher or comparable overall performance, compared with seven competitive predictors.ConclusionWe introduced an ensemble learning approach for PPI prediction that integrated multiple learning algorithms and different protein-pair representations. The extensive comparisons with other state-of-the-art prediction tools demonstrated the feasibility and superiority of the proposed method.
Memristor effect in GeO[SiO2] and GeO[SiO] solid alloys films

The p-Si(or n-Si)/GeO[SiO2] (or GeO[SiO])/indium-tin-oxide (ITO) structures were fabricated by simultaneous evaporation of GeO2 and SiO2 (or SiO) powders in high vacuum and further deposition of ITO contacts using the magnetron sputtering technique. The structural properties of the GeO[SiO2] and GeO[SiO] films were studied using FTIR and Raman spectroscopy. According to Raman data, the GeO[SiO] films deposited at a temperature of 100 degrees C contain amorphous Ge clusters. Their current-voltage characteristics were measured in the air atmosphere, and resistive switching (memristor effect) was observed in structures without a preliminary forming procedure. The Shklovskii-Efros percolation model gives a consistent explanation for the charge transport in the high-resistive state and the low-resistive state of memristors based on GeO[SiO2] or GeO[SiO] films.

In order to elucidate the charge density wave (CDW) nature in LaAuSb2, we have carried out the electrical resistivity, Hall coefficient, Seebeck coefficient, thermal conductivity, as well as ultrafast pump-probe spectroscopy measurements on single crystalline LaAuSb2. The CDW phase transition has been characterized by marked features near T-C similar or equal to 88 K. In particular, the obtained Hall carrier concentration and electronic thermal conductivity exhibit significant reduction as T-C drops, providing strong evidence for partial gapping of the Fermi surfaces during the CDW phase transition. Furthermore, the ultrafast pump-probe spectroscopy reveals pronounced oscillatory features in the photoinduced transient reflectivity in the CDW ordered state. A characteristic oscillation mode with frequency of about 0.32 THz was extracted. The comparison of the obtained oscillation frequency with the frequencies of the amplitude mode in the well-studied CDW analogue LaAgSb2 allows us to ascribe the observation to the amplitude mode of CDW collective excitations in LaAuSb2.
Impact of the surface recombination on InGaN/GaN-based blue micro-light emitting diodes

In this work, the size-dependent effect for InGaN/GaN-based blue micro-light emitting diodes (mu LEDs) is numerically investigated. Our results show that the external quantum efficiency (EQE) and the optical power density drop drastically as the device size decreases when sidewall defects are induced. The observations are owing to the higher surface-to-volume ratio for small mu LEDs, which makes the Shockley-Read-Hall (SRH) non-radiative recombination at the sidewall defects not negligible. The sidewall defects also severely affect the injection capability for electrons and holes, such that the electrons and holes are captured by sidewall defects for the SRH recombination. Thus, the poor carrier injection shall be deemed as a challenge for achieving high-brightness mu LEDs. Our studies also indicate that the sidewall defects form current leakage channels, and this is reflected by the current density-voltage characteristics. However, the improved current spreading effect can be obtained when the chip size decreases. The better current spreading effect takes account for the reduced forward voltage.

This study proposes a two-stage approach to perform metafrontier analysis of the pollution efficiency of administrative regions in Taiwan during 2004-2015. The empirical research shows that New Taipei City and Taipei City have the best performances in terms of metafrontier efficiency and the technology gap ratio. In addition, the average score for pollution efficiency in municipalities is higher than that in non municipalities for three environmental management indices. However, the metropolitan and non metropolitan regions face different environmental problems in that the former should pay attention to sewage treatment, while the latter should focus attention on preventing air pollution. Finally, Taiwan presents disparity in the environmental technology gap ratio between these two types of regions. (C) 2019 Elsevier Ltd. All rights reserved.

This paper proposes a new two-dimensional (2D) Butler matrix antenna array with 16 switching beams for tile-based beamforming. This study fabricated and assembled a 3.5-GHz Butler switching antenna array using multilayer Rogers printed circuit board technology. It adopted a new design concept and layer-by-layer vertical connection architecture. This 2D Butler matrix antenna array does not require long coaxial cables to connect functional circuit interfaces, which is an improvement over the traditional Butler matrix beamforming network (BFN) antenna array and may facilitate considerable reductions in circuit volume and complexity.
Asymmetries in Porous Membranes: Fabrication of Anodic Aluminum Oxide Membranes with Double-Sized Nanopores and Controlled Surface Properties

Recently, anodic aluminum oxide (AAO) membranes with ordered and monodispersed nanopores have attracted significant attention because the pore sizes and lengths of the AAO membranes can be systematically controlled by changing the anodization parameters. Asymmetries of geometry, wettability, charge, and polarity in nanoporous AAO membranes are now highly desired for applications such as drug delivery, membrane filtration, and catalysis. Although the asymmetries in AAO membranes have been widely studied, AAO membranes whose nanopores simultaneously possess more than two asymmetric properties still need to be developed. In this work, we present a simple method to fabricate asymmetric AAO membranes by combining the post-treatments with the three-step anodization method. The asymmetries of the AAO membranes simultaneously possessing larger nanopores with higher hydrophobicity and smaller nanopores with lower hydrophobicity are characterized by scanning electron microscopy, water contact angle measurements, and energy-dispersive X-ray spectroscopy. Using the asymmetric AAO membranes, nanowires of polystyrene and poly(styreneb/ock-dimethylsiloxane) with double-sized diameters are also fabricated via the melt and solvent wetting methods, exhibiting that the AAO membranes with double-sized diameters can be used as the templates for generating double-sized polymer nanowires.
