Summary: This study reports the synthesis of gold nanoparticles using chemical reduction in batch and microreactor methods. A parametric study was conducted to analyze the effect of several factors on the size of the nanoparticles, and the best conditions obtained were used to synthesize gold nanoparticles in a glass chip microreactor. The results show that the microreactor method consistently produces smaller nanoparticles in a shorter reaction time.

Summary: A new variational Gaussian regression filter is proposed in this paper by incorporating variational parameters into a linear parametric Gaussian regression process. The filtering evidence lower bound serves as a quantitative evaluation rule for different filters, and a relationship between F-ELBO and M-ELBO is identified. The accuracy performance improvement of VGRF can be theoretically explained based on these findings.

Summary: This study explores the application of physics informed neural networks (PINNs) as a low-cost physics-based simulation approach for the thermal analysis of the laser powder bed fusion (LPBF) process. PINNs solve the heat transfer equation parametrically and provide reliable transient and steady-state temperature profiles for single-track LPBF depositions. The trained PINNs can calculate temperature profiles and melt-pool dimensions during the LPBF process with practically zero computational cost. The reliability of PINNs outcomes is verified through ground-truth data based on benchmark finite element simulations.

Summary: This study investigated the adsorptive removal of the organophosphate diazinon pesticide using porous pumice adsorbent. The optimal removal conditions were obtained at pH=3, adsorbent dosage=4 g/L, contact time=30 min, and initial pesticide concentration=6.2 mg/L.Isotherm, kinetic, and thermodynamic models were used to analyze the adsorption process.

Summary: A new bacterial strain, Bacillus cereus AKAD 3-1, was found to degrade cypermethrin in an aqueous medium. The degradation was optimized using central composite design and artificial neural network-genetic algorithm. The results showed that the process variables significantly affected the biodegradation of cypermethrin. The strain successfully converted cypermethrin into non-toxic products.

Summary: Through the use of a homemade dynamic vacuum system, fully crystallized VO2 (M) was successfully synthesized at high temperatures (>500°C) in a single step involving the decomposition of vanadyl ethylene glycolate (VEG) and the crystallization of VO2. Maintaining vanadium valence (+4) and controlling the microstructure of VEG are crucial in determining the size and shape of the final product. This method is deemed suitable for the mass production of VO2 nanoparticles.
