Research activity of Prof. J. Molenda is carried out in three main fields: Lithium ion Batteries, Solid Oxide Fuel Cells and High Temperature Superconductors.
Her studies focus on basic research concerning physicochemical properties of materials and their optimization as well as on technological aspects of application of the studied materials in Li-ion batteries and SOFC. The main area of interest in Li-ion batteries covers mechanisms of electrochemical intercalation of alkaline metal ions into transition metal compounds MaXb (M = transition metal, X = O, S) with layered or 3D framework structure. Proposed electronic model of the intercalation process allow for prediction and design of operational properties of intercalated electrode materials.
Her comprehensive study of structural, transport and electrochemical properties of transition metal oxides lead to the designation of an important relationship between the crystallographic structure, electronic structure, transport properties and reactivity in relation to lithium.
Establishing this relationship is extremely important for the design of functional properties of the materials for Li-ion batteries. Professor J. Molenda is the author of over 140 publications in the field of Li-ion batteries and fuel cells with international circulation.
Nitrides at the nanoscale
My research focuses on the characterization and exploitation of nanoscale structures in GaN-based materials. The broad aim of my work is to achieve improved performance in GaN-based optoelectronic devices and to develop and implement novel device concepts.
Novel microscopy techniques for nitride semiconductors
To improve the performance of GaN-based devices we need to understand their structure and electronic properties on a micro- to nano-metre scale. New techniques are being developed to meet the demands of this unusual semiconductor. Our work involves: (a) applications of atomic-force microscopy (AFM) to studies not only of nitride surface topography but also of the electrical properties of nitride materials at length scales as small as 10 nm; and (b) exploiting the three-dimensional atom-probe microscope (3DAP) to determine the composition of GaN alloys, particularly InGaN quantum wells, in 3D, at a sub-nanometre scale. Increasingly, we try to combine these techniques together to give the as complete a picture as possible of the properties of an individual defect or nanostructure.
GaN-based single photon sources
Early single-photon sources emitting in the visible spectral region were based on heavy attenuation of a laser; such sources are intrinsically unreliable, and may emit multiple photons. In contrast, we aim to build a single-photon source, based on InGaN quantum dots, that is reliable and easy to operate. Such a device would find broad application in quantum cryptography and quantum computing, particularly as the emission wavelength of the InGaN dots is rather convenient in terms of available detectors. However, the high defect density and unusual electrical properties of GaN make realising the device a challenge.
Prof. Pileni's research has been highly interdisciplinary over her entire scientific career. Her major breakthroughs are: (i) A fundamental understanding of the kinetics and mechanisms in colloidal solutions guided her in the preparation of either nanocrystals with different sizes and shapes or the chemical modification of enzymes. (ii) Formation of thermodynamically stables states of self-assemblies either by using surfactant molecules (supraaggregates) or inorganic nanocrystals (supracrystals). (iii) Collective optical and magnetic properties induced by dipolar interactions and due to the nanocrystal arrangements in 1D, 2D and 3D superlattices. (iv) Physical intrinsic properties such as vibrational, magnetic and crystal growth related to the nanocrystals ordering in supracrystals (3D). (v) Chemical intrinsic properties due to nanocrystals ordering.
Research interests include new materials and novel device concepts for future nanoelectronics, in particular, semiconducting nanowires for applications in electronics, optoelectronics and energy harvesting and molecular electronics.

Spaldin uses a combination of first-principles and phenomenological theoretical techniques to study the fundamental physics of novel materials that have potential technological importance. Projects combine development of new theoretical methods, application of the methods to existing materials, design of new materials with specific functionalities and subsequent synthesis of the "designer materials".
Specific materials classes of interest are:
Transition-metal-oxides with "strong correlations", in which the behavior of each electron explicitly influences that of the others.
Contra-indicated multifunctional materials, which combine multiple, technologically desirable functionalities that tend not to co-exist.
Multiferroics, which are simultaneously ferromagnetic, ferroelectric and ferroelastic and/or ferrotoroidic.
Materials with multiple coupled or competing instabilities, which in turn show strong responses to electric or magnetic fields or strain.
