“…Based on the experiment, the maximum temperature difference range is from 0.3323 • C to 0.4871 • C (morning, 12.00 a.m. to 6.00 a.m.), 0.3407 • C to 0.7842 • C (evening, 6.00 p.m. to 12.00 a.m.), and 2.0 • C to 6.072 • C (day, 6.00 a.m. to 6.00 p.m.). Refer to [2] for details. From the results, understanding the real-time temperature variation at TEG's hot and cold sides due to solar radiation in Malaysia was achieved.…”

Harvesting energy from solar radiation in Malaysia attracts the attention of researchers to utilize the potential by ongoing improvement. Roofing material with low albedo absorbs the heat, that can then be harvested using a thermoelectric generator. Previous research only measured the open-circuit voltage with different thermoelectric generator configurations. Low power output limits the potential to be utilized. The low output power can be increased using a DC converter. However, the converter must be tuned concerning low- and high-voltage levels, bipolar, and the maximum power point tracking. Therefore, this paper presents a dual-level voltage bipolar (DLVB) thermal energy harvesting system. The circuit is tested at constant and various time intervals to evaluate the system’s functionality and performance. Experiment results show that the proposed harvesting system can boost from 0.6 and 1.6 V to achieve the optimum level. The mean efficiency of the harvesting circuit obtains 91.92% at various time intervals. Further, the field test result obtains output power from 1.45 to 66.1 mW, with the mean efficiency range of 89.62% to 92.98%. Furthermore, recommendations are listed for future research.

“…Thermoelectric generators, use the Seebeck effect shown in Figure 3a, to generate electricity from heat. Once there is a temperature gradient (ΔT) across the thermoelectric couple composed of n-type and p-type semiconductor materials [20]. The mobile charged carriers located at the hot end (heat source) diffuse to the cold side (heat sink), thereby creating an electrostatic potential (ΔV).…”

Adsorption of polymers is a phenomenon of great importance in a number of areas of our daily life. However, understanding this phenomenon is essential. This work focuses on the theoretical study of the polyethylene glycol (PEG) adsorption phenomenon on thenatural clay-layer surface. Clay is considered as a matrix. Different adsorption regimes have been presented. The expressions of the surface coverage ratio as a function of the volume fraction of monomer for each regime were calculated. A strong adsorption was noted for the first two regimes (dilute surface, and bidimensional semi-dilute surface) confirmed by the exponential term. When the surface becomes saturated, we are in the plateau regime for which the adsorption varies logarithmically, due to the occupation of most of the sites available on the clay-layer surface. Finally, we presented the variation of the volume fraction as a function of 𝑧(axis perpendicular to the surface), we have shown that a layer of polyethylene glycol (PEG) adsorbed on a natural clay-layer surface is composed of three zones (proximal, central and distal) with different volume fractions.
