With the continuing advances in technology, electrical energy storage has become increasingly important. Among storage devices supercapacitors’ distinct qualities, such as a long lifespan, quick charge/discharge speeds, and high-power density, make them viable substitutes for traditional batteries. In this study a simple hydrothermal method was used to synthesize a h-MoO3/graphene oxide (GO) composite for such applications. The crystal structure, morphology, and chemical bonding were characterized using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and Raman spectroscopy. XRD confirmed the hexagonal crystal structure, and no changes were observed after GO incorporation. The FESEM images revealed that the nanosheets of GO and hexagonal rods MoO3 were well coupled with the GO sheets. The electrochemical properties of the pure h-MoO3 and h-MoO3/GO composites were studied using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). The nanocomposite electrode demonstrated a specific capacitance of 134 Fg-1 at a current density of 3 mA/cm-2, an energy density of 26.8 Wh/kg-1, and power density of 560 W/kg-1 in an aqueous acidic electrolyte 1 M H2SO4, which is notably higher than that of pure MoO3. This indicates the promising electrochemical performance of MoO3/GO composite for supercapacitor applications. The enhanced capacitive performance may have resulted from the decrease in the charge transfer resistance (Rct), calculated from the Nyquist plot. Furthermore, the composite material exhibited stability and a capacitive retention of 76 % after 1,000 cycles. This confirms the benefits of incorporating GO to enhance material retention for better long-term results. The results of this study demonstrate its potential to advance energy storage technology. Maintaining the hexagonal crystal structure of h-MoO3 while incorporating GO improves the composite’s structural stability, an important factor for reliable long-term use. Moreover, the observed reduction in crystallite size due to the presence of GO suggests improved electrochemical performance.

Electrical and thermal transport properties of a polycrystalline carrier-doped wide-gap semiconductor LaCu1-δ S0.5Se0.5O (δ = 0.01), in which the CuCh (Ch = S, Se) layer works as conducting layer, were measured at temperatures 473~673 K. The presence of δ = 0.01 copper defects dramatically reduces the electrical resistivity (ρ) to approximately one part per million compared to that of δ = 0 at room temperature. The polycrystalline δ = 0.01 sample exhibited ρ of 1.3 × 10-3 Ωm, thermal conductivity of 6.0 Wm-1 K-1, and Seebeck coefficient (S) of 87 μVK-1 at 673 K. The maximum value of the dimensionless figure of merit (ZT) of the δ = 0.01 sample was calculated to be 6.4 × 10-4 at T = 673 K. The ZT value is far smaller than a ZT ~ 0.01 measured for a nominal LaCuSeO sample. The smaller ZT is mainly due to the small S measured for LaCu1-δS0.5Se0.5O (δ = 0.01). According to the Debye model, above 300 K phonon thermal conductivity in a pure lattice is inversely proportional to T, while thermal conductivity of the δ = 0.01 sample increases with increasing T.

Bio-efficacies of two different types of fungicides, Diniconazole and Paclobutrazol with their effects as plant g rowth regulators f or Kimchi Cab bage were e valuated o n February 4 to A pril 13, 2024 in Los Baños, Laguna, Philippines. The experiment was done during the off-season planting of Kimchi Cabbage in the country. Yield and other horticultural characteristics were observed for seven different groups: group 1, untreated control; group 2, recommended rate of granular fertilizer (RR-G); group 3, recommended rate of granular fertilizer plus recommended rate of Diniconazole; group 4, recommended r ate of D iniconazole (alone); g roup 5 , recommended rate o f Paclob utrazol (RR-PBZ), group 6, RR-G plus RR-PBZ; and group 7, RR-G plus ½ RR-PBZ. Results showed that combination of recommended rate of granular fertilizer plus the full recommendation of Paclobutrazol (group 6) resulted in a significantly higher yield of 64.9 tons/ha than other groups with yields ranging from 23.3 to 55.3 tons/ha. Such significantly higher yield in group 6 was also attributed to the number of leaves produced by plants at the time of harvest. Regarding effects of two chemical treatments, the combination of Diniconazole a nd P aclob utrazol a s recommended granular f ertilizers h elped in t he heading of K imchi Cabbage during hot conditions with an average temperature of 32-35°C from March to April at the heading stage plus a f actor of b eing planted a t a lowland area i n the country. T he a dvantage o f Paclobutrazol aside from yield is its availability in the country as compared to Diniconazole (Binnari).

This study investigates the role of the NAC transcription factor ANAC032 in regulating abscisic acid (ABA)-dependent stress responses and its involvement in sugar signaling pathways. Arabidopsis seedlings with overexpressed or knock-out ANAC032 were examined for their sensitivity to ABA, glucose, and fluridone to elucidate the functional role of ANAC032 in ABA and high glucose-mediated growth retardation. Our results showed that ANAC032 negatively regulates ABA responses, as ANAC-overexpressing plants exhibited higher ABA sensitivity, while anac032 mutants were less sensitive. Under high glucose conditions, anac032 mutants demonstrated hyposensitivity, with germination rates higher than wild-type and ANAC032-overexpressing plants. Additionally, yeast two-hybrid screening identified three NAC proteins, ANAC020, ANAC064, and ANAC074, interact with ANAC032. These findings highlight ANAC032’s role in stress signaling pathways and its potential interactions with other NAC proteins, contributing to a better understanding of transcriptional regulation in plant stress responses and possibly expanding to forage crop development.
