Efficient eco-friendly synthesis of carbon nanotubes over graphite nanosheets from yellow corn: a one-step green approach

The present work reports the synthesis of multi-wall carbon nanotubes (MWCNTs) over graphite nanosheets by an easy and simple approach without using any external catalyst. Simply, yellow corn seeds were thermally annealed in a hydrogen atmosphere at 1050 °C for 3 h without any pretreatments. Notably, the growth of MWCNTs was observed to preferentially occur on the outer surface of the corn shell. This uncomplicated approach not only emphasizes the feasibility of synthesizing carbon nanomaterials using agricultural by-products but also underscores the potential applications of these synthesized materials in various fields. Samples were examined through a comprehensive analysis employing various techniques, including scanning electron microscopy (SEM), Raman spectroscopy, FTIR, X-ray diffraction (XRD), and high-resolution transmission electron microscopy (HRTEM). The findings unveiled the formation of rolled graphene accompanied by the presence of vertical multi-wall carbon nanotubes (MWCNTs) positioned over stacked graphene sheets. This detailed characterization provides insights into the structural features and arrangement of the synthesized materials, paving the way for a deeper understanding of their potential applications. The pyrolysis temperature is a crucial factor in the morphological characteristics of the synthesized carbon nanostructures. While graphene cage-like structures were obtained at 800 °C, small carbon nanotubes were grafted to larger ones and formed three-dimensional hierarchical morphologies when the annealing temperature increased to 900 °C. The growth mechanism of the carbon nanotubes was explained based on the jet self-extrusion of the generated gases through the inherent pores of the corn seeds. The current technique employed in manufacturing MWCNTs shows significant promise as a green synthesis method for producing catalyst-free MWCNTs suitable for industrial applications including sensors and energy storage materials.

Design of a Corn Shelling Machine with an Elastic Collision System Using Iron Chains

Corn is an agricultural product that is in great demand among farmers, because the process and care methods are not too difficult and the lifespan of corn from planting to post-harvest is 2 months. In the general production process, during shelling, many farmers still use the method of shelling using their hands or simple tools, so it requires quite a long production time. The reason people still shell them using their hands or tools is because the price of the machines is too expensive and they don't even know about corn shelling machines. The machine designed to develop a simple corn sheller for use by farmers in Merauke Regency has a capacity of ± 300 kg/hour. The impact system is used in this shelling machine to reduce the impact on the corn kernels. For this reason, in corn shelling, iron chains are used that can move elastically and flexibly.

Conversion of corn shell as biomass solid waste into carbon species for efficient decontamination of wastewater via heavy metals adsorption

Biomass-based solid residuals can be of serious hazardous environmental impacts if left for natural degradation. Thus, the proper utilization of such residuals is highly recommended. Therefore, one of solid residuals: namely, corn shell, was used in this study to synthesize carbon species (labeled as CS-C) as an adsorbent for efficient removal of heavy metal ions from aqueous solution. The structural properties and the textural characteristics of the prepared carbon species were verified. The present charges on the carbon surface were acquired via zeta potential analysis. The performance of CS-C, as adsorbent, was investigated through batch technique. Adsorption isotherm was optimally described using the Langmuir model reflecting that the removal process occurs at the homogenous surface of CS-C through a chemical reaction (surface complexation mechanism). The equilibrium state for the sorption process was reached after 4 h of interaction. The kinetic studies revealed the nice fit of heavy metal removal process to Pseudo-second-order model and the thermodynamics is matched to endothermic, spontaneous, and feasible sorption process. The displayed results could emphasize the high potentiality of CS-C to act as a remarkable sorbent for efficient tackling of water contaminants.

Agricultural land in Juwiring Village in the Cepiring sub-district, Kendal Regency, depends on rainwater for irrigating its rice fields. Rice fields in Juwiring village are planted with corn. In one year, farmers in Juwiring village can harvest corn 3 times. By using a solar powered corn sheller machine, farmers can save Rp. 20,000 per sack because there is no need to pay any more for the corn sheller, besides that with this machine you can save fuel because the fuel uses abundant solar power and the solar corn sheller machine is an environmentally friendly machine because it doesn't emit air pollution. In the previous study (Ekoanindiyo, 2020), from the results of the previous design there were several inputs from users, namely the hole for inserting corn was not too high so that farmers had to squat to put corn in. The diameter of the hole is not big enough so if there is corn with a large diameter then the corn cannot enter the hole. For the corn shelling process, it is inserted one by one into the hole so that the shelling process will take a long time. For the disposal site on the previous sheller machine there were two drain holes, namely the disposal of corncobs and the disposal of corn. When the machine is running, the corn cob does not come out of the cob drain hole but comes out together with the corn. The cobs and corn should come out separately, the corncob coming out of the corncob hole while the corn will come out of the corn dispensing hole. In the hole in the sheller machine place the sack so that the corn and corncobs can enter the sack. Development of a corn sheller machine design to improve the previous machine design including farmers in shelling corn do not need to squat so as to reduce fatigue when shelling. The holes for the cobs and corns to come out can be separated. The diameter hole for inserting corn is rather wide so that all sizes of corn can enter and when inserting corn into the machine you don't need one but you can do it directly in large quantities so that the shelling process can be completed more quickly. The research approach is with interviews and observations using anthropometric data of users. Using measurements of the body dimensions of farmers in the Village Farmer Group in Cepiring District as many as 5 people with elbow height body dimensions. The conclusion related to the development of the corn sheller machine design is the development of the corn sheller machine design using anthropometric data on the body dimensions of farmers in the Village Farmer Group in Cepiring District as many as 5 people.

Bandar Klippa Village is one of the villages in Percut Sei Tuan sub-district, Deli Serdang Regency, North Sumatra Province with an area of ​​1,828.4 Ha. In the village of Bandar Klippa, most of the agricultural land out of a total of 575 hectares is planted with corn with an average yield per hectare of 20 tons if there is sufficient rainfall. Generally, corn farmers immediately sell their crops to the factory after they have been harvested. The price of corn if it is sold directly to the factory is around 2800/kg, namely whole corn and the corn cob because the farmers do not yet have a corn sheller. If shelling is done, the price of corn increases to IDR 4,200/kg or almost 2 times that. This service is intended to help corn farmers get added value to their corn yields by providing a corn sheller machine designed by the proposing team and providing training in the use and maintenance of the sheller machine so that it can be used for a long time. After being crushed, the corncobs can also be sold to cattle breeders at a price of around Rp. 1000 to Rp. 2000 for each kilogram. The sheller machine can shell 350 kg of corn every hour

Biopolymer‐based sachets enriched with acorn shell extracts produced by ultrasound‐assisted extraction for active packaging

AbstractAcorn shell residue is valorized for the efficient obtention of antioxidant extracts by ultrasound‐assisted extraction and applied in the development of biopolymer‐based films, studying its influence in different matrices for the subsequent preparation of emitting sachets for active food packaging. The effect of increasing extract addition on the physical, mechanical, optical, and antioxidant properties of biopolymer films is studied. It is observed that the water resistance increases with increasing amounts of extract in PVA films and from 5% extract in chitosan films. Furthermore, 3% extract in both types of matrices increases the UV‐light blocking capacity (up to 97%). Considering the mechanical performance, not weakening of the structure is observed because of the extract addition. Films possess radical scavenging activity against DPPH with the incremental amounts of extract. Moreover, acorn shell extract as active additive in biopolymer‐based sachets demonstrates an effective delay of soybean oil oxidation during 10 days of storage.
