“…In this study, phosphoric acid (H 3 PO 4 ) has been used as an activating agent to open pores and enlarge the surface area of AC, so that the adsorption power will increase [ 12 ]. H 3 PO 4 removes impurities contained in the carbon [ 13 ], as a result of the carbonization process of biomass such as ketones, alcohols, acids, and aldehydes. Moreover, H 3 PO 4 also helps to form a bridge that connects the fragments of biopolymers (layer of carbon structure) by forming phosphate bonds that make pores more open and enlarge the surface area.…”

Wood-dust of Dalbergia sisoo (Sisau) derived activated carbon (AC) was successfully tested as an adsorbent material for the removal of rhodamine B dye from an aqueous solution. The AC was prepared in a laboratory by the carbonization of wood powder of Dalbergia sisoo at 400 °C in an inert atmosphere of N2, which was chemically activated with H3PO4. Several instrumental techniques have been employed to characterize the as-prepared AC (Db-s). Thermogravimetric analysis (TGA)/differential scanning colorimetry (DSC) confirmed that 400 °C was an appropriate temperature for the carbonization of raw wood powder. The FTIR spectra clearly confirmed the presence of oxygenated functional groups such as hydroxyl (–OH), aldehyde/ketone (–CHO/C=O) and ether (C–O–C) at its surface. The XRD pattern showed the amorphous structure of carbon having the 002 and 100 planes, whereas the Raman spectra clearly displayed G and D bands that further confirmed the amorphous nature of carbon. The SEM images displayed the high porosity, and the BET analysis revealed a high surface area of 1376 m2 g−1, a pore volume of 1.2 cm3 g−1, and a pore size of 4.06 nm with the coexistence of micropores and mesopores. The adsorption of dyes was performed by varying the dye concentration, pH, time, and the sample dose. The maximum percent of RhB dye removal by AC (Db-s) was 98.4% at an aqueous solution of 20 ppm, pH 8.5, an adsorbent dose of 0.03 g, and a time of 5 min. This study proved to be successful in addressing the local problem of wastewater pollution of garment and textile industrial effluents using locally available agro-waste of Dalbergia sisoo.

“…Studies have suggested that it has potential for ecosystem support, and its chemical components could be extracted for applications in the medicinal, cosmeceutical, and pharmaceutical fields (Akihisa et al, 2004;Yongram et al, 2019). Its resin can also be used as gasoline-and diesel-like fuel for engines (Suiuay et al, 2019) and can provide benefits in support and provisioning-type services, particularly in riparian forests (Asanok et al, 2017;Kamyo and Asanok, 2020). Additionally, it can provide shade for edible mushrooms (Butkhup et al, 2018;Kaewgrajang et al, 2013).…”

Coupled with newly introduced technology, sustainable agriculture is considered a cooperative strategy for lowincome countries to improve farm productivity and economic growth. This study focuses on analyzing the process of adoption intention with a new technology associated with the use of Dipterocarpus alatus, a large tree species restricted to Thailand. A conceptual framework of the technology acceptance model (TAM) has been applied to explain farmers' decision-making processes. The purposive sampling approach targets farmers in the area who have D. alatus trees on their properties. Structural equation models, latent variables, and the hypothesized adoption intention interactions are the primary tools used in analyzing the decision-making process. Results showed that adoption intention concerning D. alatus technology was significantly influenced by perceived ease of use and attitudes based on experience and environmental sensibilities. This study has extended the application of TAM, providing insight into decision-making processes that are not hindered by technology implementation.

“…One category is about the research of blended combustion for the internal combustion engine [23,24]. The other category is about the research of product optimization for oil processing [25,26]. The research with the keywords of the ratio of gasoline to diesel ratio (or something like this) seldom belongs to the field of macroeconomics.…”

Gasoline to Diesel Consumption Ratio: A New Socioeconomic Indicator of Carbon Dioxide Emissions in China

In recent years, gross domestic product (GDP) has grown rapidly in China, but the growth rate of carbon dioxide (CO2) emissions has begun to decline. Some scholars have put forward the environmental Kuznets curve (EKC) hypothesis for CO2 emissions in China. This paper utilized the panel data of 30 provinces in China from 1997 to 2016 to verify the EKC hypothesis. To explore the real reasons behind the EKC, the index gasoline to diesel consumption ratio (GDCR) was introduced in this paper. The regression results showed that CO2 emissions and GDP form an inverted U-shaped curve. This means that the EKC hypothesis holds. The regression results also showed that a 1% GDCR increase was coupled with a 0.118186% or 0.114056% CO2 emission decrease with the panel fully modified ordinary least squares or panel dynamic ordinary least squares method, respectively. This means that CO2 emissions negatively correlate with GDCR. From the discussion of this paper, the growth rate reduction of CO2 emissions is caused by the economic transition in China. As changes of GDCR can, from a special perspective, reflect the economic transition, and as GDCR is negatively correlated with CO2 emissions, GDCR can sometimes be used as a new socioeconomic indicator of carbon dioxide emissions in China.
