“…Simplifying Equations ( 8) and (10) for 1:1 acid-extractant complex, Equation ( 11) is obtained. The experimental values of the equilibrium complexation constant (K 11(exp) ) for the reactive extraction of 2-furoic acid in octanol, chloroform, and diethyl ether using TOA were estimated from Equation (11), as listed in Table 5.…”

“…The electricity for the electrochemical oxidation or photoelectrochemical oxidation of furfural could be obtained from renewable resources (solar and wind). [10][11][12][13][14] Importantly, 2-furoic acid is used as a precursor to generating 2,5-furandicarboxylic acid (FDCA), used in biopolymers. The commercialization of FDCA generated from 2-furoic acid using electrochemical oxidation or photoelectrochemical oxidation is more economical than the chemical route.…”

Electrochemical conversion of biomass to value‐added chemicals has gained impetus in recent years. Herein, we present a methodology for recovering biomass‐derived 2‐furoic acid from the dilute aqueous stream by reactive extraction. The reactive extraction was performed using a chemical extractant, trioctylamine (TOA), with diluents (octanol, chloroform, and diethyl ether). Equilibrium parameters influencing the recovery of 2‐furoic acid were evaluated. Using TOA in various diluents, the 2‐furoic acid was recovered with 85%–99% efficiency. A 1:1 complex of the 2‐furoic acid—TOA was formed in the organic phase, and the experimental equilibrium complexation constant was compared with that obtained from the relative basicity and Langmuir models. The equilibrium parameters were used for column design to estimate the solvent to feed ratio (S/F) and the number of theoretical stages (NTS). The NTS required is 12 to attain 99% recovery of 2‐furoic acid in counter‐current extraction. The present study sheds light on the reactive extraction process adopted for process intensification with electrochemical conversion, paving the way for the commercialization of valuable products obtained from biomass.

“…Operating at the microscale, it offers many advantages including a larger surface‐area‐to‐volume ratio, enhanced mass and photon transfer, fine flow control, and uniform light distribution. [ 80 ] Microfluidic photoelectrochemical cells have successfully converted solar energy into hydrogen, [ 81 ] methanol, [ 82 ] ethanol, [ 83 ] and formic acid. [ 84 ] Rarotra et al had developed a simple inverse Y‐shaped microfluidic photoelectrochemical cell (also known as a microfluidic electrolyzer when splitting water) to produce hydrogen and oxygen at the two outlets.…”

While the majority of the technologies developed for energy storage are macrosized, the reactions involved in energy storage, such as diffusion, ionic transport, and surface‐based reactions, occur on the microscale. In light of this, microfluidics with the ability to manipulate such reactions and fluids on the micrometer scale has emerged as an interesting platform for the development of energy storage systems. Herein, the advances in utilizing microfluidic technologies in energy storage and release systems are reviewed in terms of four aspects. First, miniaturized microfluidic devices to store various forms of energy such as electrochemical, biochemical, and solar energy with unique architectures and enhanced performances are discussed. Second, novel energy materials with the desired geometries and characteristics that can be fabricated via microfluidic techniques are reviewed. Third, applications enabled by such microfluidic energy storage and release systems, particularly focusing on medical, environmental, and modeling purposes, are presented. Lastly, some remaining problems and challenges and possible future works in this field are suggested.

“…Two-phase flows in microgravity are used in a wide variety of critical applications including fluid handling and storage, as well as thermal and power systems on spacecraft (e.g., condensers, evaporators, piping system). Numerous researchers have conducted a study on the uses of two-phase flow [1][2][3][4][5]. Furthermore, Lee and Mudawar [6] described a high-heat-flux microchannel heat sink with a two-phase flow for chilled chilling applications, as well as its properties of transfer of heat.…”

The middle name of author "Musawa Yahya Almusawa" was incorrect and has been corrected.]Couple Stress Fluid (CSF) incorporates a new material constant whose, in contrast to a Newtonian fluid, regulates both couple stress and lubricant viscosity.Due to the fourth-order spatial derivative term that this material constant introduces into the momentum equation, this fluid (CSF), even for classical fluid problems, has received limited research. The aim of this article is to examine the joint impact of heat transmission and magnetic field on a time-fractional model of two-phase free convection flow of dusty fluid that is electrically conducting. Among parallel plates, one of which is stationary and the other of which is oscillating with constant velocity, the CSF is supposed to flow. Heat is transferred by free convection and buoyant force, which generates the flow. Furthermore, all spherical dust particles are uniformly dispersed through the fluid. The flow is modeled mathematically in terms of PDEs. The provided derived system of PDEs is generalized by applying a recently invented fractional derivative, the Caputo-Fabrizio fractional derivative. Finite sine Fourier and Laplace transformations are jointly applied to handle the problem. The velocity and temperature profiles have closed form solutions. The CSF outcomes for stimulating fluid parameters are shown in numerous graphs for CF time fractional derivatives. Additionally, the influence of various parameters has been discussed. Mathcad-15 is used to plot the graphical outcomes for the CSF, dust particle, and temperature profiles. Furthermore, the skin friction and Nusselt number are calculated. Table 1 demonstrates how the rate of heat transmission reduces as the Peclet number's value rises. Similarly, Table 2 demonstrates that the skin friction increases as the magnetic parameter and couple stress parameter are raised. Table 3 and 4, shows the Regression analysis that the variation in the velocity for Couple stress and dusty fluid parameter are statistically significant. By increasing the couple stress parameter 𝜆, retarde the both velocities profile.
