“I. G. Murgulescu” Institute of Physical Chemistry

______

Brief history

The Institute of Physical Chemistry was founded by Academician Ilie Murgulescu in 1963, as a result of splitting of the former Chemical Research Center of the Romanian Academy.

Outstanding personality of the Romanian chemistry, Professor Murgulescu is also the founder of the modern school of physical chemistry at the University of Bucharest. He devised the main research directions in physical chemistry and set up the structural framework of the Institute of Physical Chemistry, developed under his direction (1963 - 1977) and preserved with minor revisions for over 40 years.

For mostly political reasons, especially after the Professor’s retirement, the institute was forced into a sinuous administrative trajectory, eventually resulting in the loss of its dedicated building and legal personality. In spite of these shortcomings, its research staff was able to develop professionally and get ready for the major changes of the year 1990. Professor Ilie Murgulescu survived those troubled times and had a decisive contribution to the return of the Institute of Physical Chemistry back to the Romanian Academy. After his passing away in 1991, Academician Ilie Murgulescu made the last and unanimously expected gift to the Institute of Physical Chemistry: his name.

Research directions and infrastructure

1. Laboratory of quantum chemistry and molecular structure (Dr. Marilena Vasilescu) is mostly concerned with studies of electronic structure, molecular confirmation and reactivity of molecules and free radicals. Problems related to the structure of self-assembled systems (micelles, reverse microemulsions, liquid crystals), structures of layered compounds, molecular spectroscopy (ESR, IR, UV-VIZ, fluorescence), TPD, TPR and magnetic measurements. Lattice-theory axiomatics of quantum mechanics is applied to certain problems concerning chemical systems.

ESR lab

2. Laboratory of chemical thermodynamics (Dr. Speranta Tanasescu) is focused on two major fields: (1) thermodynamics of gaseous and condensed mono and multi-phase systems; (2) biothermodynamics and thermodynamical characterization of amino-acids, proteins and bacteria in solid state, solution and controlled atmosphere.

3. Laboratory of chemical kinetics (Dr. Domnina Razus) is involved in two projects concerning homogeneous gas-phase reactions (hydrocarbon oxidation in flames) and heterogeneous catalytic processes (hydrogen and hydrocarbon oxidation catalyzed by oxides and supported metal catalysts). The study of combustion and flames is focused on the initiation and propagation processes of deflagrations under non-steady conditions, with straightforward applied research extension concerning safety recommendations. Heterogeneous catalysis studies are concerned with the dynamics of gas-solid interaction with application to the selection of new catalysts and new chemical sensors and experimental investigation and modeling of oscillatory behavior of several heterogeneous processes.

Explosion lab

4. Laboratory of surface chemistry and catalysis (Dr. Mariuca Gartner) is involved in three projects. The correlation between solid surface reactivity and the appearance of adsorption states expected in both solid-gas and solid-liquid interfaces are studied. Various solids such as single crystals of IB group metals and transitional metal mixed oxides are characterized by work function variation, cyclic voltammetry, TPR and TPD, and electron spectroscopy. Oxidation processes of practical importance like oxidative coupling of methane, total oxidation of hydrocarbons and alcohol oxidation on inorganic membranes are also investigated.

Elipsometry lab

5. Laboratory of electrochemistry and corrosion (Dr. Eugen Roman) is focused on metal (semiconductor) / electrolyte interface, aiming at establishing its structure and the mechanism of electrode reaction. Among several subjects of study there are: electrochemical sources, solar energy conversion, electrochemical synthesis and oxide electrocatalysis. The corrosion processes of metals and alloys in aqueous and non-aqueous media are also investigated in order to establish efficient protection methods against corrosion in industrial equipment.

6. Laboratory of molten salts (Dr. Nicolae Ene) is specialized in obtaining physical-chemical data (phase diagrams, density, viscosity, electrical conductivity), pertaining to various molten salts and oxide systems and in finding the mechanism of processes involved in their practical applications. The basic and applied aspects related to the electrochemistry of light and refractory metals and electrosynthesis of special materials (borides, nitrides) are studied. Heat storage and heat transfer in molten salts regarding their utilization in non-conventional energy sources are also investigated.

Conductance lab

7. Laboratory of oxide materials science (Dr. Maria Zaharescu, CM of the RA) is currently involved in the physical chemistry of solid and vitreous state aiming to elucidate thermal phase equilibria, reaction mechanisms and structure - properties correlations in oxide systems. These studies aim to improve the design and development of classical and non-conventional methods for obtaining new oxide systems and to characterize these materials from the structural and technological point of view. A distinct research field deals with obtaining ceramic materials from gels.

8. Laboratory of supramolecular chemistry and interphase processes (Dr. Titus Constantinescu) applies separation methods to the study of equilibrium and non-equilibrium processes in the supramolecular chemistry in order to separate complex mixtures, detect types of kinetic and thermodynamic parameters and establish the correlations between structure, chromatographic behavior, biological and pharmaceutical activity.

9. Laboratory of colloid chemistry (Dr. Dan Anghel) carries out research on micellization, microemulsions, polymer-surfactant interactions, transport phenomena occurring across membranes, dielectric spectroscopy, modeling and simulation in colloidal surfactant chemistry, emulsions and solid-liquid dispersions.

10. Laboratory of coordination chemistry (Dr. Luminita Patron) is involved in modern aspects of coordination chemistry of the transition metal ions and rare earth (mono and polynuclear compounds), precursors for mixed oxides with superconductive properties, spectroscopic and magnetic behavior, inductive inner coordination sphere via metal orbitals, etc. Another direction of research is the study of the correlation between the structure of the coordination compounds and their biological activity.
