“…Moreover, the average pore diameter was measured as 3 μm, 7 μm, and 15 μm for poly(AMPS-g-MBAm)/chitosan 250 mg, 500 mg, and 1000 mg, respectively. This finding aligned with the earlier results obtained during the determination of swelling ratios [24,25,26], confirming that the presence of chitosan significantly affected the hydrogel's structure and properties. The results obtained are summarized in Table 3.…”

This study entails the radical copolymerization synthesis of (2-acrylamido-2-methyl-1-propane sulfonic acid) AMPS, utilizing (N,N’methylene bis-acrylamide) MBAm as a cross-linking agent and potassium persulfate (PPS) as an initiator to produce chitosan-based composite hydrogels. The investigation involved the various masses of chitosan (250, 500, and 1000 mg). The characterization of the obtained composites and the dye adsorption process was carried out using FTIR, TGA, SEM, UV-visible, and STEM techniques. Swelling properties in distilled water were examined, revealing that the swelling rates at temperatures of 25°C and 37°C for the hydrogel of poly(AMPS-g-MBAm)/chitosan (1000 mg) exceed those of hydrogels with poly(AMPS-g-MBAm)/chitosan (250 and 500 mg). Furthermore, the sorption capacities of the dye were investigated, demonstrating that the sorption capacities of poly (AMPS-g-MBAm)/chitosan (1000 mg) at different temperatures surpass those of poly(AMPS-g-MBAm)/chitosan (250mg, and 500 mg).

“…One way to understand research trends on a large scale and intuitively see the structure and trends of research fields or journals is by analyzing scientific mapping. This bibliometric has been well-documented and applied in many areas (Al Maryanti et al, 2022;Mubaroq et al, 2020;Nandiyanto et al, 2022a;Nandiyanto et al, 2022b;Nandiyanto et al, 2022c;Nandiyanto et al, 2022d;N'diaye et al, 2022;Wiendartun et al, 2022;Yulifar et al, 2021).…”

This study presented the design of a robust controller based on Integral Sliding Mode Control (ISMC) for controlling the Vehicle Steer-by-Wire (VSbW) system. The dynamic model of the VSbW system is first developed and then the design of ISMC has been conducted via the states of the system. The VSbW system has been described by two terms; one term represents the nominal model, which is free from nonlinearities, and the other term lumps the uncertainties in system parameters. The integral sliding mode controller has been designed for controlling the VSbW system. The control design consists of two parts. The first control part has addressed the nominal term of the system, while the second control part tackles and eliminates the effects of uncertainties and perturbation due to the uncertain term of the system. The numerical simulation has been conducted to show the robustness of ISMC and its capability to reduce the chattering effect in the control signal. In addition, a comparison study in performance has been conducted between the proposed controller and other controllers in the literature. We also carry out bibliometric analysis to see research trends. Based on our analysis, the number of publications regarding the keywords "controller", "steer", and "wire system" changes every year (25 (2018), 56 (2019), 51 (2020), 71 (2021), and 61 (2022)).

“…Even small amounts (less than 1 mg/L) can cause significant problems in terms of water pollution [ 14 , 15 , 16 ]. In particular, cationic dyes have harmful effects such as skin irritation and allergic reactions, as well as carcinogenic and mutagenic toxic effects [ 17 ].…”

In the present study, the ability of an adsorbent (SLM Stem) obtained from the stem of the Silybum Marianum plant to treat wastewater containing the cationic dyes basic blue 3 (BB3) and basic yellow 28 (BY28) from aqueous solutions was investigated using a batch method. Then, the SLM Stem (SLM Stem-Natural) adsorbent was carbonized at different temperatures (200–900 °C) and the removal capacity of the products obtained for both dyes was examined again. The investigation continued with the product carbonized at 800 °C (SLM Stem-800 °C), the adsorbent with the highest removal capacity. The dyestuff removal studies were continued with the SLM Stem-Natural and SLM Stem-800 °C adsorbents because they had the highest removal values. The surface properties of these two adsorbents were investigated using IR, SEM, and XRD measurements. It was determined that the SLM Stem-Natural has mainly non-porous material, and the SLM Stem-800 °C has a microporous structure. The optimal values for various parameters, including adsorbent amount, initial dye solution concentration, contact time, temperature, pH, and agitation speed, were investigated for BY28 dye and were 0.05 g, 15 mg/L, 30 min, 40 °C, pH 6 and 100 rpm when SLM Stem-Natural adsorbent was used and, 0.15 g, 30 mg/L, 30 min, 40 °C, pH 10, and 150 rpm when SLM Stem-800 °C adsorbent was used. For BB3 dye, optimal parameter values of 0.20 g, 10 mg/L, 30 min, 25 °C, pH 7, and 100 rpm were obtained when SLM Stem-Natural adsorbent was used and 0.15 g, 15 mg/L, 40 min, 40 °C, pH 10, and 100 rpm when SLM Stem-800 °C adsorbent was used. The Langmuir isotherm described the adsorption process best, with a value of r2 = 0.9987. When SLM Stem-800 °C adsorbent was used for BY28 dye at 25 °C, the highest qm value in the Langmuir isotherm was 271.73 mg/g. When the study was repeated with actual water samples under optimum conditions, the highest removal for the BY28 dye was 99.9% in tap water with the SLM Stem-800 °C adsorbent. Furthermore, the reuse study showed the adsorbent’s efficiency even after three repetitions.
