Journal of Marine Science and Technology–Taiwan
We developed a two-scale time series framework using monthly container throughput (20-foot equivalent units, TEU) as a port activity indicator. Applied to Kaohsiung, Taiwan (2017–2024), we related TEU to near-port NO₂ and PM₂.₅ (monthly) and air quality to outpatient respiratory diagnoses (weekly) across the 2019–2020 sulfur rules and the COVID-19 pandemic. Transfer-function models indicate TEU tends to lead near-port NO₂ by 6–9 months. Structural break tests at policy dates indicate nonsignificant changes in levels and slopes, suggesting gradual rather than abrupt shifts in the activity–pollution linkage. Weekly two-pollutant distributed-lag Poisson models estimated relative risks (lags 0–8) per interquartile range (IQR) …

Triboelectric nanogenerators (TENGs) are a promising energy-harvesting technique that utilizes contact electrification and electrostatic induction to convert mechanical energy into electrical energy. Contact electrification can occur between any two surfaces that experience periodic physical contact and separation, regardless of the material type. Various materials have been investigated for triboelectrification in TENGs for different applications. Although polymers are used in TENGs, various transition metal oxides (TMOs), including binary, ternary, and doped binary/ternary oxides, have also been widely studied as filler materials to improve TENG performance. Introducing TMOs into the polymer matrix enhances the performance by increasing surface charge density and enabling …

In order to enable further advances in microelectronics, new processes capable of precisely depositing films are required. This is especially true of processes meant for depositing two-dimensional (2D) transition metal dichalcogenides, such as MoS2, a material of particular interest due to its high potential mobility even at a thickness of a few atoms. In this work, we report industry-compatible processes for depositing crystalline MoS2 with a high degree of precision. We demonstrate the successful conversion of both MoOx and MoSx films deposited via thermal atomic layer deposition using bis(tert-butylimido)bis(dimethylamino)Mo(VI) and H2O or H2S, respectively, into crystalline MoS2 films after an …

Journal of Mechanical Engineering Science and Technology (JMEST)
Renewable energy from lignocellulosic biomass is a promising alternative to fossil fuels. Coconut shell (CS) waste is a favorable precursor for porous carbon due to its high carbon content, abundance, and non-food nature. However, conventional biochar often has limited surface area and catalytic active sites, hindering its effectiveness as a catalyst. While Fe-based modifications are promising, the use of ferric nitrate-assisted activation of coconut-shell-derived porous carbon remains underexplored. This research focused on developing an Fe-doped porous carbon catalyst from CS via ultrasound-assisted impregnation, followed by activation in a tube furnace. CS biochar was produced through pyrolysis at 550 °C and …

Makara Journal of Technology
CPI systems used to spray crops in the Karbala Desert face two main problems: the cost of generating electricity with generators and the difficulty of delivering electricity from the grid to remote areas. Second, the fixed solar panels feeding some of these systems cannot produce enough electricity because they cannot track the sun’s rays. To solve these issues, appropriate actuators must be combined with these panels to form solar trackers. Due to their advantages over others, pneumatic actuators are proposed to enable the panels to constantly track the sun’s rays. This leads to the production of as much energy as …

Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters that govern microstructural features such as intraparticle voids and fuel-oxidizer mixing, and the resulting inhomogeneous shock reactivity of individual particles. To present our approach, we used a model composition 8Al⋅3CuO, previously optimized for combustion. We milled powders and prescreened different prepared batches using differential scanning calorimetry (DSC) to rule out batches with significant pre-reaction. Then …
