A universal but simple procedure for identifying the α, β and γ phases in PVDF using FTIR is proposed validated. An integrated quantification methodology individual phase mixed systems also proposed.
Nonsolvent-induced phase separation (NIPS) is a facile and cost-effective technique for the efficient fabrication of multifunctional polyvinylidene fluoride (PVDF) membranes. However, polymorphic transition PVDF during this process not well understood, although different interpretations have been proposed. Here, polymorphism solution-cast films corresponding NIPS membranes has investigated. Results show that use polar aprotic solvents normally unable to induce α → β transformation in cast...
Saccharomyces cerevisiae has been extensively employed as a host for the production of various biochemicals and recombinant proteins. The expression systems in S. typically rely on constitutive or galactose-regulated promoters, limited repertoire gene regulations imposes constraints productivity microbial cell factories based budding yeast. In this study, we designed characterized series allantoin-inducible endogenous allantoin catabolic system (DAL-related genes) cerevisiae. We first...
In x Ga 1 -x N p-i-n homojunction solar cells with different content are studied. The measured open circuit voltages (Voc) 2.24, 1.34, and 0.96 V, for x=0.02, 0.12, 0.15, respectively. By comparing the x-ray rocking curves, I-V characteristics external quantum efficiencies, it’s demonstrated that deterioration of InGaN crystal quality larger contents causes decrease Voc. result demonstrates reduction defect is a key factor in fabrication nitride cell.
Effective transformation from paraelectric to a high fraction of ferroelectric phase is crucial produce piezoelectric materials with constant for broad applications. In polyvinylidene fluoride (PVDF) thin films, both mechanical stretching and electric poling processes have been found be critical in the α → β transformation. However, PVDF fibers fabricated by electrospinning process, roles not well explored. Here, properties forcespinning, spinning process without poling, characterized...
Gap electrospinning is a facile technique to produce aligned nanofibers useful for many applications, but its potential has not yet been fully exploited in nature, leading the fiber length still limited several tens of centimeters at present. In this work, we report breakthrough production well-aligned with record and efficiency. Using suitable poly(vinylidene fluoride) solution pair parallel plates that are substrate-free negatively connected, demonstrate ease prepare length-controllable...
Abstract Artificial synaptic devices are the hardware foundation of modern computing systems which have shown great potential in overcoming bottleneck traditional von-Neumann architectures. Organic transistors garnered considerable attention due to their merits, such as low cost, weight, and mechanical flexibility. Various materials utilized for charge-capture layer organic transistors. Indium gallium zinc oxide (IGZO) is a typical metal semiconductor with wide bandgap, high carrier...
InGaN p-i-n homojunction (HOJ) and heterojunction (HEJ) solar cells (SCs) with similar width of depletion region are investigated. Through comparison both the material property device performance, it is demonstrated that HEJ exhibits much better results than HOJ, indicating preferred for fabrication SCs. Some suggestions proposed development SCs in future.

The structural and optical properties of InGaN/GaN multiple quantum wells (MQWs) with different barrier thicknesses are studied by means high resolution X-ray diffraction (HRXRD), a cross-sectional transmission electron microscope (TEM), temperature-dependent photoluminescence (PL) measurements. HRXRD TEM measurements show that the interfaces between barriers abrupt entire MQW region has good periodicity for all three samples. As thickness is increased, temperature turning point from...
A facile and effective transformation of α to β phase in electrospinning PVDF was demonstrated by adding emeraldine base polyaniline (PANI). Results from FTIR X-ray studies revealed that a very large amount the electraoctive β-phase can be obtained controlling PANI loading parameters, whereas γ-phase normally showed tiny amount, much lower than β-phase, for all samples with loading. The above results indicate addition into solution during is powerful way enhance electroactive fibers, which...
