“…7(e): series resistance ( R ESR ), charge transfer resistance ( R ct ), Warburg impedance related to the electrolyte ion diffusion ( Z w ), double layer capacitance ( C dl ) and mass capacitance ( C L ). 89 At high frequencies, the R ct – C dl circuit is responsible for the transfer of ions between the micro/mesopores of the electrode material, whereas Z w is responsible for the diffusion of electrolyte ions in the middle frequency region. At low frequencies, the nearly straight line indicates the capacitive behavior of the device which is represented by C L in the equivalent circuit.…”

“…Chemical activation.-Chemical activation is the widely used method for activating biomass-derived carbonaceous materials. 16 In this process, the biomass precursor undergoes heat treatment followed by the activation using chemical agents such as KOH, [17][18][19][20] ZnCl 2 , 21,22 H 3 PO 4 , 20,23 H 2 SO 4 , MgCl 2 , KCl, 17 etc., at a temperature in the range of 450 °C-900 °C. This method provides better pore size distribution, development, and pore volume than physical activation, resulting in high specific surface area.…”

The world is rapidly moving toward growth and energy has been a noteworthy aspect of achieving growth. Rapid growth has also led to the over-exploitation of the environment to meet energy demands. Natural resources such as coal, petroleum, and natural gas are rapidly depleting to fulfill energy demands. Using natural resources has also increased pollution, and, consequently, detrimental climate change is knocking at our door. Many countries are trying to follow the Paris agreement to control the Earth's rising temperature. One of the ways to achieve this is to utilize renewable resources for energy generation and storage. In this context, biomass waste is a sustainable resource for producing energy storage materials. The intangible outcomes of doing so are effectively recycling the waste and reducing pollution, which is the consequence of the uncontrolled burning of biomass waste. In this review, wide-ranging scrutiny has been done to showcase biomass-derived carbon materials as suitable electrode materials for supercapacitors, fuel for catalytic activity in fuel cells, anode materials for batteries, and excellent supporting material for shape stabilizing the phase change material for thermal heat storage applications.

“…Several studies have been conducted using cassava waste (leaves and peels) to improve the surface hardness of steels [16]. This is due to the activated carbon available in cassava biomass [17][18][19][20]. Upon the tissue disruption of cassava leaf, a release of cyanogenic glucosides (CNGs) is activated [21].…”

As part of a comprehensive study on eco-friendly processing techniques, the influence of the heat treatment environment on the case hardening of AISI 1018 steel using pulverized cassava leaf was studied. The process was carried out at two different temperatures (850 °C and 950 °C) and under three environmental conditions: Process 1, the control experiment, was carried out in air only; in Process 2, the medium comprised pulverized cassava leaves; and in Process 3 a combination of pulverized cassava leaves plus barium carbonate (BaCO3) was used as an energizer (CBC mixture). Vickers microhardness testing and scanning electron microscopy were used to evaluate the effect of the processing environment on the case hardening of the steel. As expected, regardless of the processing temperature, Process 1 resulted in little or no hardening of the steel surface. However, notable case hardening occurred when the steel specimens were subjected to either Process 2 or Process 3. Furthermore, the inclusion of barium carbonate in Process 3 significantly enhanced the case hardening effectiveness of the cassava leaf in terms of the rate of and maximum hardness achieved. A maximum enhancement was observed at 950 °C. After 1 h, the increase in hardness was 160% and 280% for Process 2 and Process 3, respectively. Upon increasing the processing time to 5 h, the increase in hardness due to Process 2 was raised to 254%, while that of Process 3 remained at approximately 280%. The diffusivity of AISI 1018 was calculated using the microhardness data. The diffusivity was highest in Process 2 samples with values of 1.568 × 10−9 m2/s at 850 °C and 1.893 × 10−9 m2/s at 950 °C. Effective case hardening of AISI 1018 steel was carried out using the medium of cassava leaf, without the addition of barium carbonate (BaCO3) as an energizer.
