Title: Microplastics in the environment: Chemistry, Sources, formation, toxicity, and remediation

Abstract: Worldwide, more than 400 million tons of plastic are produced annually. These plastics break down into small particles and those with a length of < 5 mm are called microplastics (MPs). The World Health Organization (WHO) has identified MPs as an emergency pollutant for the environment and human health. MPs hold toxic chemicals (such as plasticizers and colorings) that are used as ingredients during the polymerization process. Moreover, MPs act as transport vectors of other hazardous substances (pesticides, heavy metals, and biofouling), which can accumulate in the environment and induce toxicity to biodiversity. In addition to the inhalation of MPs, their existence in drinks and foods is the main pathway for entering the human body. The accumulation of MPs in the human body places people at risk for respiratory problems, cytotoxicity, and inflammatory as well as autoimmune illnesses. Therefore, it is crucial to identify the safest and most effective strategies for removing MPs from the environment. This presentation provides a comprehensive summary of MPs and discusses advances and challenges in removing them from our environment.

Title: Circular Materials

Abstract: “Biomass growing and harvesting; mineral and fossil resource extraction; and processing of materials, fuels and food accounted for more than 55% of global greenhouse gas emissions in 2022 and more than 60% if land-use change impacts are considered.” – reports the international resource panel in their 2024 global resource outlook. An inadvertent surge in material usage by 60% than the 2022 levels is predicted; if the current habits of sourcing and processing prevail, the future of a liveable planet Earth is uncertain. One of the most viable ways to develop sustainable materials is to source them from bioresources, which itself is carbon negative, and functionalize and value add them for various applications. Most bioresource waste contains lignocellulosic materials, using which high quality cellulose and carbon can de synthesized. The cellulose thus derived are developed, with appropriate chemical modifications, as a scaffold for tissue engineering, as an electrolyte for energy storage applications, and as membranes for various applications. Further, other bioresourced natural polymers such as seaweeds are toughned using cellulose nanocrystals and developed into high strength biopolymers. High quality graphitic nanocarbons were developed from various bio and laboratory wastes and developed as high performing charge storaging electrodes via developing thin metallic or metal oxide films or appropriately utilizing the larger voids in porous carbon. Besides, materials were also processed from fresh and end-used resources using solar light to lower the embodied energy. High performing energy storage devices were developed using these electrodes and electrolytes with appreciable voltage window, specific energy and power and cycling stability. These developments will be discussed in the lecture.

Title: In situ formation of polymethylsiloxane nanofilaments on pristine cotton stalk with natural interconnected pores for rapid and recyclable organic solvents absorption

Abstract: The creation of a superhydrophobic surface with simplified hydrophobic steps still faces great challenges. Herein, an in situ one-step hydrophobic strategy of growing polysiloxane nanofilaments onto pristine rod-shaped cotton stalk (CS) surface is used to prepare a new bulk superhydrophobic CS absorbent. The rich hydroxyl groups contained in CS directly polymerize with the silanols generated by the hydrolysis of methyltrichlorosilane on CS surface to form polysiloxane nanofilaments, leading to a change in the wettability of the CS surface. This strategy makes the water contact angle of the prepared absorbent as high as 161°, representing exceptional water repellency. Benefiting from the unique natural interconnected pore structures, the absorbent takes only 20 s to reach absorption equilibrium, showing rapid absorption performance toward organic solvents. The absorbent still maintains good absorption capacity even after 20 absorption-desorption cycles, holding excellent recyclability. The proposed hydrophobic modification approach simplifies the steps to the surface hydrophobization of CS, which provides a new strategy for the preparation of biomass-based superhydrophobic materials.
