The CO2 atmospheric concentration level hit the record at more than 400 ppm and is predicted to keep increasing as dependence on fossil fuels inevitable. electrocatalytic conversion becomes an alternative due its environmental energy-friendly properties benign operation condition. Lately, bimetallic materials have drawn significant interest electrocatalysts their distinct properties, which parents' metal cannot mimic. Herein, indium-bismuth nanosphere (In16Bi84 NS) was fabricated via facile...
The electrochemical CO2 reduction reaction (CO2RR) to form C2+ products was investigated obtain high selectivity in liquid CO2-fed systems having the limitation of low current density. Over past decade, flow cells with gas diffusion electrodes (GDEs) have emerged achieve densities close industrial-relevance scale by overcoming limitations. However, key parameters GDE design, including binders, were not sufficiently identified enhance and density for products. Nafion, FAA-3, polypyrrole used...
As a biodegradable material, chitin possesses exceptional physical and chemical properties, making it valuable in various industrial sectors. Compared to chitin, its derivative, chitosan, offers even more versatile applications due higher solubility reactivity. the key precursor for chitosan production, is typically harvested from shrimp crab exoskeletons. However, quest alternative sources has intensified reduce reliance on crustacean-derived chitin. Black soldier fly (BSF, Hermetia...
Electrocatalytic reduction of CO2 to formate has become one way increase the value and overcome climate change issue. Novel catalysts for critical role enhancing reaction selectivity have been continuously explored provide best performance. Lately, composite materials drawn much attention because synergistic effect between components provides enhanced physical chemical properties. Here, we present a highly efficient on tin(IV) oxide/zinc oxide (SnO2/ZnO) electrocatalyst with grainy hollow...
In many farm operations, implements must follow the rows of crops. Doing this, tractor operator frequently looks back, twisting his body while checking work being done. This is not only difficult, but also prone to errors. To improve this system and obtain labor savings, a study an automatic crop row guidance for use in mounted implement was conducted. Specifically, laser sensor, which most important part system, developed. The sensor applied three-dimensional vision consisting distance...
The extraction ofCannaedulisKer. starch from its rhizome was performed using 2 different types of press (hydraulic and screw press) with the addition Na-metabisulphite NaOH (in range concentration 100 - 5000ppm each). optimum condition for thisprocess determined by Central Composite Design experiment statistical calculation solved Design-Expert7.0.0. targets observed responses were high yield, low ash, fiber, carbohydrate content. results showed that yield reduction fiber only influenced...
Thin-layer drying experiments were conducted on cassava chips and grates at three levels of temperatures (30, 50 70°C) two airflow rates (0.4 0.8 m 3 /m 2 /s). Results indicated that both rate the air temperature significantly affected characteristics grates. The higher rate, was rate. Furthermore, curves (drying vs. moisture content) showed only a falling period evaluated. Three thin-layer equations (Lewis equation, modified Page equation diffusion equation) evaluated using non-linear least...
Energy from edible and inedible root crop roots tubers using galvanic cell processing waste waters through microbial fuel (MFC) technology was harnessed. Electrolyte in the tapped for microorganisms act as catalyst MFC. In cell, optimized responses of badiang, cassava sweetpotato were greatly affected by surface area distance between anode cathode electrodes. An increase nata-de-coco membrane size MFC increased voltage current 4.94 11.71 times, respectively. Increasing width also enhanced...
Fresh leaves are sensitive to high temperature so that appropriate drying method should be selected dry leaves. This study aimed determine the effect of methods on physico-chemical characteristics and antioxidant capacity taro (Colocasia esculenta), sweetpotato (Ipomea batatas), stevia (Stevia rebaudiana), malunggay (Moringa oleifera) Fresh, healthy mature taro, sweetpotato, stevia, were subjected solar drying, mechanical sun drying. The parameters evaluated in this included moisture...
This study determined the optimum effects of temperature, drum rotation and loading rate on drying cassava grates using rotary dryer in removing moisture from grates. A Central Composite Design was employed to evaluate a total 15 fractional treatments derived 27 treatment combinations temperature (75, 94 113°C), (15, 20 25 RPM) (5, 15, kg/h). The response surface regression obtained conditions factors predicted values stationary point water loss as well removal. Results canonical analysis...
The study aimed to develop a water jet-assisted cassava peeler and evaluate its technical performance in terms of peeling capacity, efficiency, tuber loss during peeling. Performance evaluation the developed included treatments which were combinations three methods (use circular nozzle, use flat manual using knife) diameter ranges roots (35 ± 5mm; 45 5mm;55 5mm). Results showed that capacity with nozzle was significantly higher than but not different nozzle. used also affected methods; lower...
Tin oxide (SnO 2 ) is a well-known material that has been applied widely in various fields, such as catalyst, solar cell and gas sensor. As electrode material, its high selectivity through formate during carbon dioxide reduction reaction (CO RR) make it attractive to be explored further. In addition, found compare pure substance, composite exhibits better performance due the enhanced inner electric field at particle interface. Zinc (ZnO) becomes one of promising candidates with tin low cost,...
