![]() ![]() The material's unique properties, such as its high surface area, micropore structure, and electrocatalytic activity, make it well-suited for detecting and analyzing different analytes of interest in these fields. The researchers envision future applications of ZnCl2-activated biochar in environmental monitoring, food quality control, and medical diagnostics. The conversion of agricultural waste into high-value biochar through microwave-assisted pyrolysis, followed by chemical activation, provides a versatile material for various applications, particularly in electrochemical sensing. This innovative approach to utilizing pineapple peel waste offers a sustainable solution for resource recovery and waste reduction. The sensor's performance was comparable to or better than existing electrochemical sensors reported in the literature. It exhibited high selectivity, reproducibility (RSD=2.4%), and stability (RSD=2.6%) over ten days of storage. Furthermore, the sensor demonstrated excellent sensitivity, with a limit of detection of 0.97 µmol L−1 for nitrite. The electrochemical impedance spectroscopy revealed a 61% decrease in charge transfer resistance compared to the bare GCE. ![]() The results showed a significant reduction in charge transfer resistance, indicating improved electron transfer kinetics. ![]() The electrochemical properties of the ZnCl2-activated biochar-modified GCE were characterized using various techniques. The researchers applied the activated biochar to a glassy carbon electrode (GCE) through drop casting. The activated biochar exhibited a high surface area, micropore structure, and oxygen-containing functional groups, which are crucial for electrochemical sensing applications. ZnCl2 is a chemical agent that enhances its electrocatalytic activity. The study highlights the potential of transforming agricultural waste into valuable resources for environmental and economic sustainability. The third phase comprised the second pyrolysis (calcinatįAYETTEVILLE, GA, USA, July 21, 2023/ / - In a new study published in the journal Waste Disposal & Sustainable Energy, researchers from James Cook University have successfully developed a high-performance electrochemical sensor using ZnCl2-activated biochar derived from pineapple peel waste. ![]() Then, the biomass was pyrolysed at 3 kW for 30 min. The first phase is biochar production using microwave-assisted pyrolysis. Since we are not a restaurant we are not equipped to handle lots of food waste, so please be respectful of our space and staff if you bring in snacks and dinner from other places and clean up after yourselves like your mama shoulda taught ya! Don't bring saucy chicken wings then play our vintage games!įor catered food that requires tables, serving utensils and other set up, we allow this only for our private bookings.The synthesis process of ZnCl2-activated biochar comprises three stages. Reserving our large table during regular operating hours is free ($20 table fee if bringing cake/snacks/etc) and requires at least a 48 hour notice and is first come first serve.Ībsolutely! We always allow outside food in the bar, as long as guests are respectful of their mess and waste. Send us a message and we can get you a quote on pricing for the evening. We do not do partial day rentals, so if you are requesting a private buyout, the price is to shut the business down to the public for the entire day. Private rentals depend on the date requested. Our 3,800 sqft bar can accommodate very large groups or if you just want to reserve our larger table for your smaller gathering, we can work with you to make your evening one to remember. We love hosting gatherings! Be it a birthday, a reunion, a team building event or office holiday party, we are the perfect space for you and your friends to gather and have fun! ![]()
