“…34 Due to its promising dielectric properties, the factory-processed Aloe vera gel was subsequently used as the dielectric layer in an organic field-effect transistor (OFET), 35 and the dielectric properties were further verified via theoretical simulation. 36 Recently, memory-switching effects have been concurrently demonstrated in a living Aloe vera plant 37 and a factory-processed Aloe vera gel-Au nanoparticle (AuNP) blend. 38,39 Although the demonstration of memory effects in the living Aloe vera plant appears to be impractical for integration into existing electronic manufacturing technologies, 37 it shed some light on exploiting the natural material for memory applications.…”

Extracted, formulated, and processed natural Aloe vera has been used as an active layer for memory applications. The functional memory device is realized by a bottom-up structure of ITO/Aloe vera/Al in which the Aloe vera is spin-coated after mixing with different concentrations of ethanol (0-80 wt%) and subsequently dried at different temperatures (50-120 °C). From the current density-voltage measurements, the device can exhibit a reproducible bipolar switching characteristic with pure Aloe vera dried at 50 °C. It is proposed that charges are transported across the Aloe vera layer via space-charge-limited conduction (SCLC), and clusters of interstitial space formed by the functional groups of acemannans and de-esterified pectins in the dried Aloe vera contribute to the memory effect. The formation of charge traps in the Aloe vera layer is dependent on the drying temperature. The drying temperature of a memory-switching Aloe vera layer can be extended to 120 °C with the addition of appropriate amounts of ethanol. The concept of using natural Aloe vera as an active material for memory applications has been demonstrated, and the read memory window, ON/OFF ratio, and retention time are approximately 5.0 V, 10(3), and >10(4) s, respectively.

Organic materials are now being used in a wide range of microelectronic applications in parallel with inorganic materials, because of their superior properties, environmental safety, and low cost. This paper describes the characterization of Aloe vera gel (AVG), a new organic dielectric material. The surface morphology, spatial distribution of elements, and structural characteristics of an AVG layer were examined using scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD), respectively. The resistance of the AVG layer, determined using a four-probe station, was 640 Ω. EDX showed that the elements contained in the layer were carbon, oxygen, aluminum, silicon, calcium, potassium, and copper. The XRD results suggested that the sample primarily consisted of bornite (Cu 5 FeS 4 ), geerite (Cu 8 S 5 ), sal ammoniac (NH 4 Cl), and carobbite (KF).

Abstract. This study examine the economic feasibility of a proposal to replace an existing Feed Gas Cooler (Cold Box) with a new unit in a gas processing complex in Malaysia. Economic justification is essential to make the decision on the feasibility of this undertaking because of the high capital investment. The mathematical model presented in the paper includes net present worth, payback period, rate of return, investment balance analysis, and sensitivity analysis. Critical analyses on four factors of the estimates were done to assess their influence on the overall economic justification of the proposal. The results indicate an acceptable return on investment. However, the proposal is susceptible to the variation in demand of the Feed Gas Load.
