Summary: Core-shell particles consisting of poly-2-methylaniline (PMAN) and carbonyl iron (CI) were successfully prepared through dispersion polymerization. The surface of CI particles was modified using dopamine as a chemical grafting agent to enhance the affinity between PMAN particles and pure CI particles. The morphology, crystalline structure, magnetic behaviors, and sedimentation stability of the prepared PMAN/CI particles were studied, and the dispersion stability was found to be better than that of pure CI particles. The characteristics of the PMAN/CI particle-based magnetorheological fluid were measured using a rheometer.

Summary: Magnetorheological (MR) fluid is an intelligent fluid influenced by an external magnetic field. Stable MR fluids based on carbonyl iron particles coated with silver nanoparticles and nickel-zinc ferrite nanoparticles as additives were synthesized. The density of the Ag-coated CI particles decreased compared to pristine CI particles. The MR fluid with a combination of silver-coated CI particles and nickel-zinc ferrite nanoparticles showed similar yield stress but higher stability compared to CI-based MR fluid.

Summary: Chi-Fe5C2, a highly active phase in Fischer-Tropsch synthesis, was successfully synthesized using a wet-chemical route without the need for pre-activation. The encapsulation of chi-Fe5C2 nanoparticles with mesoporous silica was found to effectively protect them from deactivation and re-oxidation, while maintaining their phase intact. The CO2 selectivity of stabilized chi-Fe5C2 was very low, indicating its potential as a catalyst for Fischer-Tropsch synthesis.

Summary: This research investigated the impact of magnetic field application time and frequency on the pressure performance of magnetorheological fluid (MRF). The results showed that continuous magnetic field application exerted pressure on the MRF until reaching maximum pressure, followed by a gradual decrease when the magnetic field was turned off. The pressure dropped rapidly as the magnetism disappeared, even below the initial pressure, and then gradually rose towards equilibrium pressure. Furthermore, during repeated magnetic field application, the MRF effectively generated pressure in response to the magnetic field up to a frequency of 5 Hz, with smaller pressure changes observed at higher frequencies.

Summary: This article presents the design optimization process of a hydrodynamic brake utilizing an electrorheological (ER) fluid. The optimization is based on mathematical models of the brake's geometry and electrical circuit, with parameters selected from experimental tests of a prototype brake. Six objective functions are minimized, considering factors such as braking torque, brake weight, absorbed electric power, and torque rise time. The design variables include the number of blades and the inner and outer radii of the brake's working space. Optimization calculations are conducted for two intervals of design variables, taking into account model accuracy and prototype specifications. The results provide general guidelines for optimizing hydrodynamic brakes with ER fluids and determine the possibilities for optimizing the prototype brake.

Summary: Magnetorheological elastomer (MRE), capable of magnetostriction in a magnetic field, has potential for sensor development. However, previous studies focused on low modulus MRE (<100 kPa), limiting their use due to short lifespan and low durability. This work developed MRE with storage modulus >300 kPa to enhance magnetostriction and reaction force. MREs with varying compositions of carbonyl iron particles (CIPs) showed increased magnetostriction and force with higher CIP concentration. MRE with 80 wt.% CIP achieved the highest magnetostriction magnitude of 0.075%, surpassing previous MRE technologies. This midrange modulus MRE has great potential for forefront sensor technology.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
