The rapid emergence of new illegal drugs (HHC, nitazenes, synthetic cathinones, etc.) creates a need for fast, on-site drug testing tools that can detect multiple substances in biofluids. These tools are crucial for clinicians, anti-doping experts, and law enforcement. Multiplexed portable analytical tools have a great potential to be implemented for this purposes. Moreover, such kind of instruments could be utilized in personal healthcare monitoring by enabling early-stage diagnostics of health problems. This project aims to develop electrophoresis-based analytical tools for reliable, fast and cost-effective metabolism studies in vitro, revealing the characteristics and metabolic pathways of new psychoactive substances. Additionally, new on-site biofluid testing tools (focused on oral fluid) will be developed for detecting new drugs. The results of this project will enhance drug monitoring, support public health, and improve safety.

Wood or lignocellulosic biomass more generally, is a readily available renewable resource, offering sustainable solutions for our growing human population. The core wood polymers - cellulose, hemicellulose, and lignin - serve as fundamental components, extending beyond paper production to produce valuable wood sugars, textile fibers, thermoplastics, and fine chemicals. In our project, we are developing enzyme technologies utilizing extremophilic microbe-derived enzymes to break down and modify lignin, remove toxic phenolic compounds, convert cellulose into wood sugars, and advance enzyme-catalyzed cellulose technologies. Additionally, the project focuses on advancing technologies for converting kraft, hydrolysis (and organosolv) and synthetic lignins into porous materials, thermoplastics, and cutting-edge catalysts.

The general goal of the project is to foster the transition to a fully carbon-neutral economy. The objective is to find new effective and low-cost amine-based protic ionic liquids (IL) for latent heat thermal energy storage (LHTES). ILs can be considered potential “green” phase change materials (PCM) which have received little attention despite their excellent properties, like high enthalpy of fusion, high density, stability, and the potential for utilizing renewable feedstocks for their production. The project uses both computational and experimental methods for finding the most likely ILs for LHTES applications. Consequently, the study will provide broad fundamental knowledge on the applicability of ILs considering their physicochemical properties as well as toxicity, corrosivity, and stability along with the impact of nanoparticles on their performance.

Georgia produces about 70 thousand tonnes of mandarins annually, 50% of which gets exported. Local fruit juice industry utilizes most of the mandarins left in the country to produce mandarin juice. However, the leftover mandarin pomace causes serious environmental issues as the piled up pomace waste leaches acidic decomposting products as well as essential oils into the environment. Mandarin pomace is a rich source of fine chemicals and the project will develop environmentally friendly technologies to extrat those chemicals from the waste.

The aim of this project is to apply an innovative approach to the study of the antioxidant / antibacterial properties of plant extracts used in folk medicine using structure-based fractionation, characterization by multi-instrumental methods and evaluation of activity against Gram-negative bacteria (E. coli and B. burgdorferi).

This study aims to explore the chemical composition and variability of Estonian bee pollen across different seasons and potentially different regions. The focus is on analyzing the content of various bioactive compounds, such as antioxidants, amino acids, and volatile compounds, to evaluate the nutritional value and potential of pollen as a functional food.

Experimental research for the development of asphalt mixtures with optimum lignin content.

Ukraine has a quarter of the world’s chernozems and 41.5 million hectares of agricultural land, covering 70 percent of the country. Agriculture pollutes about 60 percent of land resources and approximately 45-48 percent of reservoirs, representing 18-24 % of global GHG emissions. SmartAGRO's goal is to develop a precision fertilization solution that will help Ukraine achieve its climate policy goals. SmartAGRO is based on capillary electrophoresis technology, which enables the determination of various macro- and microelements in the soil. The goal is to develop a precise agriculture platform with recommendations for soil fertilization for agricultural crops growing in Ukraine, taking into account the chemical profile of the soil, the type and the crops grown, helping to reduce the use of fertilizers, increase/maintain yields and reduce GHG emissions.

The aim of the study is to determine the chemical composition of 30 propolis samples collected from different counties of Estonia and to study their antioxidant and antibacterial effects.

The aim of this study is to determine the physico-chemical parameters and the content of selected bioactive substances of bee bread samples collected from different counties of Estonia.

The aim of project is the determination of physico-chemical, antibacterial, bioactive and antioxidative properties of Estonian honeys as well as their effect on human heath.
