Hello Students, Alumni, Faculty, Staff, and Friends!
WQ2019 is now in full swing (week 2 already!) and things are busy as always here at the Department of Chemistry and Biochemistry.
-Students, remember that the last day to drop a course without it staying on your transcript is this Friday.
-The chem club has some events planned for February that we will announce soon. If you want to join the chem club, or learn about what they are doing, shoot them an email at firstname.lastname@example.org
-The due date for submissions to DePaul Discoveries, the CSH undergraduate research journal is Feb 1st, and we know that chemistry and biochemistry researchers are working on papers for submission.
-We had a great seminar last week from Prof. Allen from Wayne State, and this week we are having a seminar Thursday (the 17th) from a Professor from Brazil:

Food production for a rapidly growing human population is one of the major challenges for the agriculture sector. Therefore, the increasing in the uses of pesticides and fertilizers have become essential to maximize the agricultural productivity. In this context, the rapid growth of nanotechnology has led to the development of a wide range of nanomaterials intended to improve the effectiveness and safety of agricultural solutions in crop protection. Also, various nanocarriers have been developed to agricultural uses and environmental applications. These nanocarriers include nanodispersions, nanoemulsions and inorganic nanoparticles and they aims to: i) increase the solubility of the active compounds; (ii) release them slowly and/or (iii) protect them against premature degradation as well as they can increase the biological activity by the target release in organisms1,2. In this lecture will be presented the main results in the development of nanocarrier systems containing active ingredients with agricultural applications. Also, in our research group we have developed carrier systems based on several natural and synthetic matrices for the encapsulation of synthetic compounds as well as botanical compounds3–5. In addition, the developed nanopesticides were able to decrease the amount of active ingredient used to obtain the same biological activity, thus increasing the efficiency while decreasing toxicity and the environmental impacts. Therefore, nanotechnology can impact the agriculture sector, especially by the minimizing adverse problems of the use of pesticides and as the consequence decreasing the environment impacts and increasing food security6.
