Glass was made using a melt-quenching technique with a range of europium doping concentrations ranging from 0.0 to 5.0 mol%. The absorption spectra showed that photons in the visible light and near infrared ranges were absorbed by the LNKBEu glasses. Photon absorption at 394 nm can excite the mirror to emit a number of photons in the VIS region, such as 590, 613, 652, and 701 nm. The results showed that 3.0 mol% was the optimal concentration of LNKBEu glass. Therefore, 3.0LNKBEu glass was studied using Judd-Ofelt (JO) analysis, which revealed an interesting possibility of its use.

The epoxy resin and BT phase were homogeneously mixed and cast into a disk shape. Phase formation and chemical properties of these nanocomposites were identified via XRD and FTIR methods, respectively. Frequency dependence of dielectric properties for all samples was measured by LCR meter. The polarization hysteresis loops were also investigated in order to calculate the energy density of materials. From the results, it was found that the dielectric constant and loss of these nanocomposites are independent of frequency and the εr and tanδ values tend to increase with increasing BT amount. Moreover, after adding 50% of BT into the system, the energy density of nanocomposites is increased by five times compared with the pure epoxy resin while the energy loss density sharply decreases. The dielectric properties and the energy density of BT/epoxy resin nanocomposites change with BT content and strongly depend on porosity and the distribution of BT nanoparticles.Keywords: Epoxy resinbarium titanatenanocompositeenergy storage AcknowledgmentsThe authors acknowledge the facilities, and technical assistance from Nanotechnology and Materials Analytical Instrument Service Unit (NMIS) of College of Materials Innovation and Technology, King Mongkut Institute of Technology Ladkrabang.Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis project is funded by National Research Council of Thailand (NRCT).

In general, diamagnetic feature is presented in the 4f 0 BaCeO3 system down to 2 K which is chosen as a reference in the study while BaPrO3 (4f 1) and BaTbO3 (4f 7) display antiferromagnetic phase transition at TN = 11.7 and 33.2 K, respectively, measured by MPMS magnetometer. At high oxygen partial pressure and donor ion-substitution (Nb5+), the BaMO3 systems demonstrate a similar defect chemistry to titanate perovskite which compensated by Ba-vacancy. Dielectric relaxation is detected for the doublet (BaPrO3 and BaTbO3) at the antiferromagnetic phase transition region. In order to examine the magnetoelectric response, the 8 Tesla of magnetic field is applied to the samples during the dielectric measurement. BaTbO3 shows a modest magnetoelectric response around 0.2% at the antiferromagnetic phase transition while that of BaPrO3 is silent.

The sample powders of graphitic carbon nitride (g-C3N4) and copper (I) oxide (Cu2O) as N-type and P-type semiconductors, respectively, were synthesized. The semiconductors were prepared to be a composite film with alginate. The structure, morphology, and purity of the N- and P-type semiconductors were characterized using X-Ray diffraction and scanning electron microscopy techniques. Through the optical characterization, the N-type semiconductor showed the calculated energy band gap of 2.80 eV, while the P-type semiconductor was 1.90 eV. The P–N junction property of prepared samples was confirmed using a nonlinear current–voltage characteristic. After that, two flexible semiconductors were frictional paired for TENG. Through a vertical contact-separation mode, the P–N junction-based TENG produced a maximum output voltage and current of 3.90 V and 0.44 µA, respectively, with a maximum output power of 0.35 µW at 10 MΩ. In summary, the present work achieved the preparation of flexible P- and N-type semiconductors. The feasibility to harvest the mechanical energy was demonstrated in the TENG configuration.

As a result, the software aging phenomenon occurs, which ultimately degrades the performance and reliability of the software system. Aiming at the above problems, this paper proposes a hybrid model based on integrated variational mode decomposition, moving average free regression and long and short memory network (VMD-ARIMA-BILSTM) to predict the software aging problem. Firstly, the original resource utilization rate is decomposed into stationary time series and non-stationary time series by variational mode decomposition. Then, the advantages of moving average free regression and bidirectional long short-term memory network are used to predict stationary and non-stationary series respectively. Finally, the prediction results are reconstructed to obtain the final prediction results.
