2018 International Conference of Chemical Engineering and Industrial Biotechnology (ICCEIB) Preface xylene. The density of dendrimeric fibers and ensuing acidities were found to play crucial roles in enhancing the selective production of toluene and p-xylene via transalkylation and dealkylation of bulkier aromatics. Kaykobad et al.6 report on the photoeletrocatalytic reduction of CO2 to methanol using CuFe2O4 modified with grapheme oxide under visible light irradiation. Meanwhile, Khan and co-workers7 present the applicability of electroporation (EP) as a pretreatment method to inactivate methanogens from anaerobic sludge (AS) to enhance biohydrogen production using citrus wastewater as a feed source. Gusniah et al.8 provide an excellent review on the advantages of ultrasonic-assisted enzymatic transesterification over conventional enzymatic transesterification by considering the ultrasonic mechanism in accelerating the transesterification process. In the research area related to material synthesis and characterization, Saroja et al.9 report on a simple and direct pathway to synthesize a heterogeneous catalyst by covalently immobilizing a cobalt Schiff base complex on the surface of amino functionalized graphene oxide for the cross coupling of aryl halides and arylboronic acids. Jain and co-workers10 report on a cost-effective electrolytic synthesis of copper nanoparticles using copper sulfate as a metal precursor with an average size of 70 nm. Yahya et al.11 reported that the synthesis of LaFeO3 based on a gel combustion method has been improved by using citric acid as a secondary chelating agent on glucose. The synthesized samples were calcined at 600 °C. Kim et al.12 developed an energy-efficiency recycling technique operable under various reactive gases and pyrolysis time and applied it on a polymer matrix decomposition study. Thong et al.13 report on the use of a sol−gel method in which alginate was used to help prepare a carbon-coated LiNiPO4 nanocrystal aggregate with controllable surface area. They reported an average crystallite size of 43 nm, a surface carbon coating of 2− 3 nm, and a surface area of 27.47 m2/g. A paper authored by Roddecha et al.14 highlighted preparation of electrospun-based porous nitrogen-enriched carbon-coated olivine LiFePO4 nanocomposites (MF-PVA/LFP) by employing a practical electrospin technique and using affordable polymers, melamine-formaldehyde (MF) with poly(vinyl alcohol) (PVA), as the nitrogen-containing carbon precursor, followed by carbonization at various temperatures. Bakr et al.15 compared optical and electrical properties of ZnO−SnO2 composite nanofibers (CNFs) synthesized by an electrospinning technique for energy harvesting applications with similar CNFs (TiO2− SnO2) and their single component nanofibers. Because of the potential of gel electrolytes as promising candidates for use in supercapacitors, Rajan and co-workers16 systematically evaluated the internal electrochemical mechanisms with a variety

he special issue of ICCEIB 2018 is a collection of invited contributions from the presenters of the fourth International Conference of Chemical Engineering & Industrial Biotechnology (ICCEIB 2018), a biennial conference organized by the Faculty of Chemical and Natural Resources Engineering, Universiti Malaysia Pahang, August 1−2, 2018 in Kuala Lumpur, Malaysia. The organizer of ICCEIB 2018 is thankful to the Editor-in-Chief of Industrial & Engineering Chemistry Research, Professor Phillip E. Savage, and his editorial team for publication of this Special Issue. The theme for the 4th ICCEIB 2018 edition is Sustainable Technological Solutions for Industry and Society, a topic that is fast gaining traction among researchers because of the interconnectivity between sustainability and societal issues, such as food, energy, and clean water. ICCEIB 2018 attracted more than 300 highquality extended abstract submissions from domestic, Europe, Africa, and Asia-Pacific regions. Three world-renowned experts delivered their keynote talksProfessor Dr. Neal Tai-Shung Chung from National University of Singapore with a talk on designing polymer membranes for water reuse, seawater desalination, and osmotic power generation; Professor Dr. Weeratunge Malalasekera from Loughborough University, UK, with his talk entitled “Renewable energy and role of hydrogen as a future fuel,” and also Professor Dr. Nor Aishah Saidina Amin from Universiti Teknologi Malaysia with her talk on photocatalytic carbon dioxide reduction to fuels. In addition, another two speakers coming from the petrochemical and food industries shared their organizations’ sustainability efforts with all the participants. To celebrate the success of the ICCEIB 2018 conference, this Special Issue has therefore compiled 29 invited full-length contributions in the aforementioned areas. In this line, a significant number of contributions to this Special Issue focus on the reaction study. Kamaruzaman et al.1 describe a biobased polyester polyol for the polyurethane production through the esterification of azelaic acid and sorbitol, catalyzed by tin(II) oxide. They found that the best operating condition was at reaction temperature of 433 K, sorbitol to azelaic acid molar ratio of 4:1, and catalyst loading of 2 wt %, yielding 72% azelaic acid conversion after 6 h of reaction. Abbas et al.2 report on the fabrication of highly stable Ni and Co3O4 nanocubesupported TiO2 nanorods (NRs) catalyst with improved metal support interaction for steam reforming of phenol. Meanwhile, Tajuddin and co-workers3 synthesized Ni−La/SiO2 using an in situ glycine−nitrate combustion technique for methane cracking. The maximum conversion of CH4 can reach 60.0%. Al-Swai et al.4 report on the preparation of Ni-based catalysts supported on various CeO2−MgO mixed oxide compositions whereby Ni/15%CeO2−MgO achieved the maximum conversion for CO2 (95.2%) and CH4 (93.7%) without significant deactivation during the reaction. Another paper5 reports on the synthesis of dendrimeric fibrous silica HZSM-5 (HFSZ) catalysts using a microemulsion technique and ZSM-5-seeding crystallization with different oil phases; benzene, toluene, and © 2019 American Chemical Society

of polymers and cations (PVA, PEG, PEO-based Na+, and K+) toward battery-supercapacitor hybrid-type electrode, while in another separate publication,17 they demonstrated the superiority of ternary metal-terephthalate as binderless working electrodes over their single component counterparts. A preparation of ternary metal-terephthalate containing equimolar metal precursors (Co, Cu, and Ni as metal center) and terephthalic acid and its single counterparts on Ni-foam via one-step facile hydrothermal reaction was highlighted. Ho and co-workers18 report on the immobilization of Pt nanoforms on Ti0.7Ir0.3O2 support via a modified chemical reduction method using NaBH4 as a reductant agent at room temperature. It was found that Pt particle size was approximately 3 nm and well dispersed. Significantly, this approach opens a reliable way to design new electrocatalysts for fuel cells application. Meanwhile, Bauman et al.19 report on the synthesis of Ni−Pd alloys using the coprecipitation method for the purpose of selforganizing particles catalyzing the growth of carbon nanofibers. According to their findings, an addition of palladium can enhance the activity, stability, and productivity of the catalyst in the hydrogen-assisted decomposition of 1,2-dichloroethane. In the research related to recent trends in the area of separation, Lam et al.20 augmented microwave pyrolysis with steam activation to convert palm kernel shell into activated carbon (AC), subsequently tested as an adsorbent to remove herbicide 2,4-dichlorophenoxyacetic (adsorbed up to 11 mg of herbicide/g of AC) from contaminated surface water in agricultural land. Triwahyono et al.21 developed zirconiumloaded mesostructured silica nanoparticles (Zr/MSN) for the removal of hexavalent chromium (Cr(VI)) from aqueous solutions with a reported 104 mg/g maximum adsorption capacity. Ahmad et al.22 report on the investigation of emulsion stability, membrane breakage, and emulsion swelling of emulsion liquid membranes for acetaminophen removal. Another separately carried out research work23 that has utilized cellulose sourced from recycled newspapers for the fabrication of a regenerated cellulose membrane. The capacity of adsorption was evaluated via an adsorption of chromium(VI) from aqueous solution. Meanwhile, Chew et al.24 report on the synthesis of Ba-form of silicoaluminophosphate-34 zeolite membrane for the CO2/N2 separation under low CO 2 concentration; the membrane displayed good stability of up to total durability test time of 58 h. Lee et al.25 attempted to correlate between n-butane adsorption characteristics and pore characteristics of activated carbons. Finally, ICCEIB 2018 also has received contributions in the area of extraction, for example, Kumoro et al.26 report on supercritical fluid extraction employing a CO2−ethanol mixture as solvent in extracting andrographolide from dried leaves of A. paniculata, while Gimbun et al.27 report on the enhancement of thermal stability of Phyllanthus niruri polyphenols during spray drying via microencapsulation with protein. In the area of thermodynamic, Abdul Mudalip et al.28 have employed the Conductor-like Screening Model for Real Solvents (COSMO-RS) to predict the mefenamic acid solubility and molecular interaction energy, namely, electrostatic, hydrogen bonding, and van der Waals in different solvents at temperatures from 298 to 323 K. Another contribution comes from Panjapornpon and co-workers29 with their paper on devising a new strategy for the control application to enhance the CO2 absorption efficiency of a bench-scale bubble column reactor by combining the pH target optimizer with an I/O linearizing controller.
