Yitzhak Mastai is an Israeli Chemistry Professor at The Bar Ilan University. He obtained his B.Sc in Physical Chemistry from Bar-Ilan University in 1989, and in 1999, received his PhD from The Weizmann Institute of Science with Prof. Gary Hodes on Nanomaterial Synthesis.

At the Max Planck Institute of Colloids and Interfaces, Mastai spent his three postdoctoral years, working with both Prof. Markus Antonietti and Prof. Helmut Cölfen on Biomimetic Chemistry and Chiral Polymers.

In 2003 he joined the staff of the Chemistry Department at Bar Ilan, and currently is a Professor of Nanotechnology and Chemistry, leading the Chirality Nanoscale laboratory. Prof. Mastai’s earlier interests included Nanomaterial Synthesis especially Sono (electro), the Chemical Synthesis of Semiconductors and Fullerene-like Nanoparticles, and Nanomaterial characterization.

His current research is focused on Nanoscale Chirality, Synthesis and Analysis of Chiral Nanosurfaces, and Chiral self-assembled Monolayers and Polymeric Chiral Nanoparticles. Mastai and his colleagues, have gained international reputation in these fields, and have pioneered several new concepts and techniques in the following areas: SAM's for the preparation of Chiral Nanosurfaces for Chiral resolution by crystallization. Chiral ordered Mesoporous silica by Chiral polymer -Templated Synthesis. An innovative new Carbon Chiral Mesoporous, based on the Carbonization of Chiral Ionic liquids. The development of Optical Scanning Microscopy (NSOM) and Isothermal Titration Calorimetry (ITC) for the determination of Nanoscale Chirality.

He has over 120 peer-reviewed articles in print, which were cited nearly 4,300 times. Mastai has published many book chapters and edited 3 books on various aspects of nanomaterials and materials science.

Among his previous awards, were the Minerva Postdoctoral Fellowship which he received in 2000 and the Yigal Alon fellowship in 2003, for outstanding young researchers of the Israel Academy for higher education.

Prof. Mastai served as Chairman of the Chemistry Department at Bar Ilan, between 2014 and 2017.

He also served as an executive board member of the Israel Chemical Society (ICS), The Israel Vacuum Society (IVS), the editorial board of the Journal of Nanomaterials and the Israel Journal of Chemistry (IJC).

Research Summary

My primary field of research is chirality at the nanoscale, with a focus on preparation and application of nano-chiral surfaces for enantioselective processes. My research interests can be divided into several areas:

Chiral surfaces based on self-assembled monolayers

This research concerns fundamental studies of chiral surfaces based on ultrathin molecular architectures, such as self-assembled monolayers (SAMs), on solid supports. We were pioneers in the study of chiral SAMs for the preparation of chiral nanosurfaces for chiral resolution by crystallization. In a series of papers, our research group has shown that chiral SAM surfaces can be employed as resolving auxiliaries in the crystallization of amino acids from solutions. Recently we presented an innovative new type of chiral surface based on a chiral SAM coated with ceramic nanolayers that preserves the enantioselectivity nature of the chiral SAM and enables its protection. These surfaces can lead to a new class of chiral nano-surfaces with the improved characteristics that are necessary for any chiral application.

 

 

Chiral polymeric nanoparticles

This research concerns the development of polymeric nanoparticles fabricated using emulsion (mini or micro) polymerization. For example, we developed chiral polymeric nano- and microspheres that can act as chiral auxiliaries and be utilized for enantioselective crystallization. We are also developing chiral polymeric nanoparticles of controlled size and shape for other chiral applications such as a chiral stationary phase for chromatographic separations and as catalytic systems for stereoselective reactions.

 

Chiral mesoporous silica

Our group is also involved in the development of chiral mesoporous silica by chiral imprinting or by cooperative self-assembly of chiral amphiphiles and silica precursors. Our research focuses on the fabrication of chiral mesoporous materials and exploring the mechanisms involved in their formation and their chiral recognition.

 

New chiral analytical techniques

The group is also working on the development of new analytical methods to probe chirality at the nano-scale. We pioneered the development of near-field scanning optical microscopy (NSOM) and isothermal titration calorimetry (ITC) for the determination of chirality at the nanoscale.

Hagay Moshe (PhD 2014)

Metal oxide chiral thin films, synthesis and characterization

Our research deals with the preparation and study of metal oxide chiral thin films. 
The chiral structure of this type of chiral surface is based on chiral self-assembled monolayers (SAMs) coated with nanosized films of metal oxide materials by atomic layer deposition. The idea underlying this design of chiral surfaces is that the ceramic thin film coating protects the chiral SAMs that would otherwise be destroyed under the reaction conditions, thereby preserving their enantioselective nature.

Ido Fuchs (PhD 2015)

Switchable chiral surfaces, synthesis and applications 

The main goal is to prepare switchable chiral surfaces and to explore the possibility of using these surfaces for enantioselective separations. Our effort focuses on finding a suitable chiral molecule that will change its chiral property after applying an external force (physical or chemical) to the surface.

Chiral ionic liquids

The influence of long alkyl chains and chiral centers on the structure and properties of ionic liquids at interfaces are studied. Langmuir films of ionic liquids on liquid mercury are studied by tensiometry, surface specific X-ray methods and spectroscopy.  Further applications of chiral ionic liquids for chiral recognition and chiral separation are considered.

Chiral polymer nanoparticles synthesis and application for chiral separation

In our work we prepare chiral polymeric nanoparticles based on the polymerization of N-acryl amino acids monomers in miniemulsion systems (o/w). The chiral nature of those nanoparticles is proven by isothermal titration calorimetry (ITC) of chiral molecules.

Chiral silica colloidosomes, synthesis and applications

Colloidosomes have shown a high potential in a number of technological applications related to encapsulation techniques. The application of the colloidosomes strongly relies on facile and lowcost preparation methods allowing tunable characteristics such as wall thickness, rigidity and porosity. Our aim is to prepare chiral silica colloidosomes in Pickering emulsions and to explore their enantioselective ability in different chiral systems.

Irena Nemtsov (Mc.S 2015)

Antifreeze activity of surfaces based on self-assembly of antifreeze proteins

Antifreeze proteins (AFPs) are unique examples of natural antifreeze materials that have specific interactions with water and ice. AFPs, first found in the blood and tissues of Antarctic and some northern marine fishes, are essential to prevent the fish from freezing at low temperatures.
