Graphite is a commonly used raw material across many industries and the demand for high-quality graphite has been increasing in recent years, especially as a primary component for lithium-ion batteries. However, graphite production is currently limited by production shortages, uneven geographical distribution, and significant environmental impacts incurred from conventional processing. Here, an efficient method of synthesizing biomass-derived graphite from biochar is presented as a sustainable alternative to natural and synthetic graphite.

- Current methods for producing graphene nanoplatelets are not scalable or sustainable, hindering their industrial use in electronics and composites.
- Researchers developed a new method using carboxylated cellulose nanocrystals (CNCs) from grass as a green dispersant for creating graphene, achieving a conversion yield of 13.4%.
- This new technique not only improves efficiency and conductivity in printed electronics but also significantly reduces fossil fuel use and greenhouse gas emissions compared to traditional methods.
Article Synopsis
- Printed electronics is a game-changing technology used in various applications such as sensors, displays, and wearable devices, utilizing 2D materials for their excellent properties.
- Traditional methods for producing 2D electronic inks, like centrifugation, are time-consuming and inefficient, while newer methods face challenges due to low concentration requirements.
- The presented study introduces a continuous flow system using advanced ceramic membranes that enhance processing efficiency, significantly reduce environmental impact, and lower production costs for high-quality printable inks.
Additive manufacturing holds promise for rapid prototyping and low-cost production of biosensors for diverse pathogens. Among additive manufacturing methods, screen printing is particularly desirable for high-throughput production of sensing platforms. However, this technique needs to be combined with carefully formulated inks, rapid postprocessing, and selective functionalization to meet all requirements for high-performance biosensing applications.
