Electrochemical impedance spectroscopy for palm cooking oil discriminator using planar electromagnetic sensor array

Cooking oil is an important product in the Malaysia food industries. Most of the cooking oil products is based on palm oil. However, there are activities in selling cheaper cooking oil by labelling as high quality in cooking oil product. Traditional methods have been developed to measure the quality of the cooking oil product such as the chromatography technique but the cost for the system setup is expensive and requires a large amount of time to analyse the sample. Thus, a suitable and reliable system with less analysis time is needed for widespread industrial uses. This paper has presented a discriminative technique for palm cooking oil using Electrochemical Impedance Spectroscopy (EIS) with planar electromagnetic sensor array. The sensor consists of a meander sensor and an interdigital sensors which interact with the test samples. Three types of palm cooking oil such as double refined palm oil, refined and deodorized palm oil with peanut and sesame oil, and filtered palm oil were prepared. The results obtained showed that the presented technique was able to differentiate the samples between 20 kHz to 1 Mhz. The results obtained correlate with the theories on EIS technique and planar electromagnetic sensor which are presented in this paper

Synthesis of bent-core azobenzene oligosiloxane end-groups induces to polar order in liquid crystalline phases by achiral molecules

Anisotropic materials having potential applications in display and other devices, liquid crystals (LC) research has made significant progress during the last few decades. Owing to the attractive electro­optic switching characteristics, banana-shaped LCs has been attracted to the scientific attention enormously. The relationship between their molecular structure and their mesomorphic properties is one of the highly investigated research topics for bent core LCs. The polar order of these molecules, owing to their bent shape, displays interesting properties such as ferroelectric or anti-ferroelectric switching. The occurrence of superstructural chirality in the mesophase of bentcore compounds without having any chiral moiety in the molecules is not only of fundamental scientific interest but also of industrial application as this chirality can be switched in external electric fields. In this study, a new series of bent-core liquid crystals with oligosiloxane end-groups were synthesized and characterized

Energy optimization and effective control of reactive distillation process for the production of high purity biodiesel

Biodiesel is a promising renewable energy option that significantly reduces the emission of greenhouse gases and other toxic byproducts. However, a major challenge in the industrial scale production of biodiesel is the desired product purity. To this end, reactive distillation (RD) processes, which involve simultaneous removal of the byproduct during the transesterification reaction, can drive the equilibrium towards high product yield. In the present study, we first optimized the heat exchange network (HEN) for a high purity RD process leading to a 34% reduction in the overall energy consumption. Further, a robust control scheme is proposed to mitigate any feed disturbance in the process that may compromise the product purity. Three rigorous case studies are performed to investigate the effect of composition control in the cascade with the temperature control of the product composition. The cascade control scheme effectively countered the disturbances and maintained the fatty acid mono-alkyl ester (FAME) purity

Dynamic mechanical properties and morphology characteristics of rubber-toughened poly(lactic acid)

This study investigates the effect of natural rubber (NR), epoxidised natural rubber (ENR), and core-shell rubber (CSR) as toughening agents for poly(lactic acid) (PLA). PLA/rubber blends were prepared by using melt blending method in a twin-screw extruder, with the content of rubbers was fixed at 5 wt. %. All PLA/rubber blends exhibited lower storage modulus compared to neat PLA. Two-stage storage modulus (E’) was also observed, where the first stage occurred at lower temperature corresponded to the glass transition temperature (Tg) of rubber components, whereas the second E’ corresponded to the Tg of PLA. The impact fracture surface of PLA/rubber blends also exhibited phase- separated morphology where the spherical-shaped rubber particles were clearly present in the PLA matrix

Obstructive and restrictive spirometry from school age to adulthood: three birth cohort studies

Background: Spirometric obstruction and restriction are two patterns of impaired lung function which are predictive of poor health. We investigated the development of these phenotypes and their transitions through childhood to early adulthood. Methods: In this study, we analysed pooled data from three UK population−based birth cohorts established between 1989 and 1995. We applied descriptive statistics, regression modelling and data-driven modelling to data from three population−based birth cohorts with at least three spirometry measures from childhood to adulthood (mid-school: 8–10 years, n = 8404; adolescence: 15–18, n = 5764; and early adulthood: 20–26, n = 4680). Participants were assigned to normal, restrictive, and obstructive spirometry based on adjusted regression residuals. We considered two transitions: from 8–10 to 15–18 and from 15–18 to 20–26 years. Findings: Obstructive phenotype was observed in ∼10%, and restrictive in ∼9%. A substantial proportion of children with impaired lung function in school age (between one third in obstructive and a half in restricted phenotype) improved and achieved normal and stable lung function to early adulthood. Of those with normal lung function in school-age, <5% declined to adulthood. Underweight restrictive and obese obstructive participants were less likely to transit to normal. Maternal smoking during pregnancy and current asthma diagnosis increased the risk of persistent obstruction and worsening. Significant associate of worsening in restrictive phenotypes was lower BMI at the first lung function assessment. Data-driven methodologies identified similar risk factors for obstructive and restrictive clusters. Interpretation: The worsening and improvement in obstructive and restrictive spirometry were observed at all ages. Maintaining optimal weight during childhood and reducing maternal smoking during pregnancy may reduce spirometry obstruction and restriction and improve lung function. Funding: MRC Grant MR/S025340/1
