“…Changing the coinjection ratio and total injection flow rate did not affect the CO 2 content. This finding is somewhat contradictory to the results in the literature, 55 but we note the fundamental difference between high-pressure samples in a closed system (this research) and low-pressure samples in an open system in the literature. The results suggest that the gas content of CO 2 nanobubble dispersions at high pressure is less sensitive to the injection parameters than that of low-pressure nanobubble dispersions in an open system.…”

“…PKC was purchased as powder from Tokopedia (https://www.tokopedia.com/). Nanobubbled water was generated by dissolving ambient air into aquadest according to the method which had been described by Alam and colleagues (2022) [7], until their density was ≥ 100 per mL. At that time, the average size of the bubbles was less than 100 nm, while their average zeta potential was around -20 mV.…”

Palm kernel cake (PKC) is the remaining of a palm (Elaeis guineensis) kernel after its oil is separated. Oversupply of this biomass could become an environmental problem. Meanwhile, its moist property makes it suitable for a hydrothermal carbonization to afford added values for the biomass and overcome its potential environmental problem. From the hydrothermal processes of PKC with aquadest and nanobubbled water at 200 ºC for 6 hours, nanodots with the size around 50 nm were obtained. The nanodots may be decorated with amides on their surface. Upon illumination by an ultra-violet A wave (350 nm), the nanodots emitted lights with a maximum around blue region (450 nm). No significant differences were found between the nanodots from the hydrothermal carbonizations of PKC with aquadest and the ones from the hydrothermal carbonizations of the biomass with nanobubbled water. The fluorescence property of nanodots from PKC opens up the possibility for these carbon materials to be applied in agriculture. To the best of our knowledge, this kind of research has never been reported before.

“…Nanobubbles have been reported to be negatively charged at pH values from 4 to 12 and zeta potential values from −4.3 to −62 mV, respectively. At neutral pH, the measured zetapotential values were between −20 and −30 mV [34][35][36].…”

Adsorption refrigerators are a compelling ecological alternative to compressor refrigerators; global warming forces us to constantly look for alternative sources of energy and cold. Cold production in adsorption chillers is based on the use of heat generated by other processes running in the company. Waste heat from production processes, which has, until now, been irretrievably lost, is a potential source of energy for generating cold via an adsorption unit producing chilled water. Cooling optimizes the use of the heating network in summer and can lead to increased electricity production while reducing heat supply losses. Thus far, attempts to implement adsorption refrigerators for widespread use have not been successful as a result of the low efficiency of these devices; this is directly related to the poor heat and mass transfer conditions in the beds and heat exchangers of adsorption refrigerators. The solutions used so far, such as new working pairs, glued beds or modifications to the structure or cycle length, are still not strong enough for these devices. Therefore, it is necessary to look for new solutions. Using micro- and nanobubbles as media to increase mass and heat transfer in refrigerators is an innovative and pioneering solution. Thus, this document describes the most important features of micro- and nanobubble technology applications in adsorption refrigerators. This article is an introduction and a basis for the implementation of further research, consolidating the existing literature as a review.
