Prof. Simos Malamis from the National Technical University of Athens (Greece) delivered a series of lectures and lab sessions over the period of 16-20 September on the biological treatment of wastewater (activated sludge systems). Members of ESTg participated the training which was organised in the framework of the ORAU project “Development of a Novel Technology for Production of High Quality Reclaimed Water: Track Etch Membrane Bioreactor” led by Prof. Arkhangelsky (PI) and Prof. Inglezakis (Co-PI).
This summer Bekassyl Battalgazy, a member of ESTg, participated in a 3 month internship at The Molecular Foundry, Lawrence Berkeley National Lab. He worked on the project which of fabricating and developing synthetic process for conversion of transition metal dichalcogenides. Transition metal dichalcogenides (TMDs) are an interesting class of semiconductor materials due to their emergent properties when reduced to thin 2D layers. Moreover, after completion of his internship he presented research outputs at the 2019 Annual Nanoscience Conference at Berkeley Lab. In this project ESTg collaborated with Prof. Tikhonov from the School of Sciences and Humanities.
ESTg group is hosting an experienced scientist Dr. Aldo Capobianchi, CNR, (Italy, Rome) from 2-18 September 2019, who is an expert in the field of nanoparticles and composites design, synthesis and characterization. Dr. Aldo is training a group of research assistants and graduate students of Nazarbayev University on the synthesis of silver nanoparticles, magnetite nanoparticles, magnetite and graphene oxide nanocomposites with silver nanoparticles that could be applied in adsorption of organic and inorganic pollutants from water.
Prof. Mait Kriipsalu and Prof. Kaja Orupold visited Nazarbayev University from 2 to 6 September. They participated in teaching activities involving the third and fourth year B.Sc. students of Civil & Environmental Engineering department as well as in site visit to the city landfill and waste mechanical treatment facility. The visit was in the framework of the European project: Erasmus+ Program International credit mobility Key Action 1: Learning mobility of Individuals, lead by V. Inglezakis (PI) in collaboration with the Estonian University of Life Sciences (2018-2019).
ESTg is pleased to announce that the new paper was accepted for publication in Journal with high impact factor 7.34 – 2D Materials Journal. This is an outcome of the research project focused on the synthesis of 2D transition metal dichalcogenides (TMDs) and done in collaboration with the Berkeley Lab and Prof. Tikhonov and Prof. Inglezakis from NU. We are proud that one of the authors is ESTg member, undergraduate student Aldiyar Kuntubek, who participated in a 2 month internship at The Molecular Foundry, Lawrence Berkeley National Lab, one year ago.
We wish even greater results of the successful collaboration!

The purpose of the visit was to strengthen the bonds between the research groups and identify possible areas of collaboration. Joe Bear ( Lecturer in Inorganic Chemistry), Rosa Busquets (lecturer in Analytical and Forensic Chemistry) and Patric Melia (postdoc working on synthetic sorbents for the removal of heavy metals and organic pollutants from water) delivered presentations on their research and had a lab tour organised by ESTg team.
Bekassyl Battalgazy, a BEng in Chemical Engineering student, is participating in a 3 month internship at The Molecular Foundry, Lawrence Berkeley National Lab, starting in May 2019.
This internship position is hosted by Dr. Tevye Kuykendall, a Senior Scientific Engineer at The Molecular Foundry.
The research project focuses on the synthesis of 2D transition metal dichalcogenides (TMDs). TMDs have received a lot of attention recently, stemming from the discovery of emergent properties when reduced from bulk crystals to 2D layers, such as their transition to direct band gap, emerging charge density waves, high mobility, and valley polarization. Recently a new technique for synthesizing 2D TMDs through conversion of metal-oxide thin films deposited by atomic layer deposition (ALD) had been developed. The research aims to develop a synthetic process,
which is comprised of two steps. First, metal oxide precursor is formed on a Si/SiO 2 substrate using Atomic Layer Deposition (ALD), covered with protecting layers of SiO 2 , patterned and etched to expose the metal-oxide edge. Second, the metal-oxide is converted to the TMD at the exposed edge by lateral diffusion of a chalcogenide source gas at high temperature.
The materials will be characterized by means of optical microscopy, scanning electron microscopy, Raman spectroscopy, and other techniques.
It is important to note this year is the 4th when our students have the internship at one of the world’s best labs!
