Brushless direct current (BLDC) motor speed performance is an essential component that must be considered in the electric vehicle drive system. This research aims to obtain transfer function from mathematical modeling of BLDC and optimization so a high transient response received. The method used this study identify system parameters then model them using structure autoregressive exogenous (ARX) polynomial model. Meanwhile, get performance, done with hybrid intelligent controller. experimental findings indicate process utilizing bat yielded most favorable response. resulting values for proportional gain (Kp), integral (Ki), derivative (Kd) were determined 31.2685, 7.7375, -1.1934, respectively. In investigation, minimum frequency value 6381934.619. Also are characteristics, which include rise time 0.289 seconds, settling 10.9 overshoot 3.4%, peak 1.04 seconds. Furthermore, closed-loop demonstrates stable behavior terms stability.

The Indonesian government has submitted its plan for nationally determined contributions (NDCs) to the United Nations and committed achieving net-zero emissions (NZEs) by 2060. While looking reduce from forestry, prioritised a transition renewable energy in sector. However, Indonesia faces challenges owing lower-middle-income status, limited budgets constraints attracting international finance. This paper aims assess Indonesia's potential realising goals. It evaluates country's economic strength, past experiences current status of ongoing initiatives. concludes that significant progress is possible, but NZEs 2060 remains major challenge.

Photoreforming enables simultaneous H2 production and organic synthesis in a one-pot system. In this study, single-step approach was employed to fabricate atomically dispersed Ni Zn3In2S6 (NixZIS) for benzyl alcohol photoreforming. While neat ZIS exhibits high selectivity toward hydrobenzoin via C-H activation C-C coupling, its evolution rate remains below feasible levels. Incorporating single atoms significantly enhances activity by improving the carrier dynamics, resulting an optimal of 9.13 mmol g-1 h−1 on Ni4ZIS, over five times higher than ZIS. The presence also alters selectivity, suppressing coupling products promoting benzaldehyde generation. induce facile O-H following ZIS, inhibiting desorption carbon radicals causing consecutive oxidation benzaldehyde.

ZnxIn2S3+x has emerged as a promising candidate for alcohol photoreforming based on C-H activation and C-C coupling. However, the underlying structure-activity-selectivity relationships remain unclear. Here we report with varying Zn:In:S ratios visible-light-driven furfuryl reforming into H2 hydrofuroin, jet fuel precursor, via S-• radicals are directly identified catalytically active sites responsible in alcohol, promoting selectivity toward hydrofuroin. The optimum activity derives from trade-off between enhanced carrier dynamics diminished visible light absorption x value increases. Further, higher Zn-S:In-S layer ratio prolongs lifetime Zn-S layer, delivering coupling product selectivity. findings represent step further establishing sulfide-based photocatalysts sustainable production organic photoreforming.
