Publication date: October 2018Source: Nano Energy, Volume 52Author(s): Feng Zhu, Shihao Ji, Jiaqi Zhu, Zhenghua Qian, Jiashi YangAbstractSome piezoelectric materials, such as zinc oxide, are semiconductors simultaneously. Usually, the semiconductive property of these materials is omitted in the study of piezoelectric characteristics. However, due to the small sizes of some piezoelectric devices, such as nanogenerators, the semiconductive property may have an appreciable impact on the wave motion characteristics and potential output. In this paper, we study the influence of semiconductive property for the improvement of nan...

The QCM showed two types of the frequency decrease behaviors, that is, i) a quick shift due to the gas property change caused by the trichlorosilane gas introduction into the ambient hydrogen and ii) the continuo...

The oriented photonic TNTs are assessed by the RctCdl (ΩF) product, which is a measure of the intrinsic photoelectrocatalytic activity (IPA) of the material. The RctCdl product decouples any surface area effects and it can be applied at ...

Memory devices annealed in a hydrogen environment exhibited unipolar resistive switching behaviors with low set, reset, and forming voltages owing to reduction of the HfOx film by the injected hydrogen. The devices annealed at 400 °C exhibited good endurance, lasting 7 times as long as non-annealed device. This impr...

Research attention has recently been focused on developing simple ways of fabricating large-area OSSC arrays by means of solution-coating techniques. However, the lack of control of the meniscus front, where the nucleation and grow...

Publication date: Available online 20 August 2018Source: Materials LettersAuthor(s): Baofu Hu, Jian Xu, Jian Wang, Bingguo Liu, Baoli DuAbstractTransparent and conductive aluminum-doped zinc oxide (AZO) thin films were developed using a sol-gel method and annealed in 95 N2/5 H2 forming gas. The pressure effects of forming gas on the structural and electrical properties, and the underlying mechanisms were investigated. XPS analysis reveals that the fraction of the chemisorbed oxygen in the annealed film in 0.01 MPa 95 N2/5 H2 did not exhibit any apparent change compared to the non-annealed films, while the oxygen vacancy co...

In this study, complex drug-cellulose acetate (CA) composite films were designed and fabricated possessing pre-determined grid spacing for inter-connected fibrous films. Ibuprofen (IBU) was selected as the active ingredient. and grid spacing was varied between 300 to 500μm (fiber diameter∼35μm) for various geometries. Process parameter impact on fiber morphology and deposition was investigated. FTIR confirmed IBU encapsulation and XRD analysis indicated the drug was dispersed (amorphous) in films. Inter-connected grid void geometry was shown to impact water contact behavior, and drug release mechanism was shown t...
