His achievements were widely recognized by the scientific community.

The method turned out to be able to obtain the global minimum for the widely accepted global optimisation test functions set either in the shortest time, or analytically, without any computations [J.

This is why predicting the lowest-energy conformation or configuration represents a formidable task. Letters 7, L.

Piela Delta 9, kdantowa L. The ground state electronic energy represents a complicated function of the nuclear coordinates. Initially he employed the explicitly correlated basis introduced earlier by James and Coolidge. Letters M. B7, L. Long-range interaction of the unit cells the periodic structure is composed of turned out to represent a serious numerical problem with an effort increasing exponentially with polymer sizesince the interactions of a reference cell with the rest kwantosa the polymer decayed very slowly.

Thanks to enormous effort of the protein folding community it is possible to design such amino acid sequences, which fold to the desired protein 3D structure. The molecules, if synthesised, might be considered as molecular memory, molecular switches, etc.

Letters 12, L. Letters 86, L.

The challenge to find this conformation from a given sequence of amino acids is known as a “second genetic code”. As shown by other authors the DEM method is related to several equations of physics: Information about Professor Lucjan Piela Main scientific activity Other fields of activity Original articles and books Selected other publications Additional:.

S14, J. The book has two Polish editions, the second English edition is under way. Letters 15, L. The authors have proved a theorem indicating how the multipole expansion has to be modified to remove such a dependence [L.

Professor Piela together with Leszek Stolarczyk proposed in a new kind of isomers. The idea of deformation is based on a destabilisation of all minima of a function by introducing smoothing techniques Diffusion Equation Method, DEM, distance scaling method, shift method, also related to them: He received his bachelor degree in in his home town Rzeszow from the years old Konarski College.

After World War II he quickly completed high-school education and entered the University of Poznan to study chemistry and physics. During this extremely difficult time his courage and dignity remained an inspiration to his friends. B 22, ].

USA, In he became the first recipient of the Annual Medal of the Kwantlwa Academy of Quantum Molecular Sciences and later, inhe became a member of this Academy.

USAL. B22, J. Professor Piela and Anna Jagielska have proved by ab initio calculations that indeed in some substances a single electron transfer requires a considerable amount of energy, while a few such transfers need negligible energy.

Another subject of his research was muon-catalyzed fusion. Only the chhemia – not the original one – multipole procedure possesses this property. This work established important theoretical limits on the possible yield of muonic catalysis and contributed significantly to our understanding of this phenomenon.

The key step was using the multipole expansion, and then sum up exactly the appearing multipole-multipole contributions.

Even for relatively small molecules this function may have many minima in the corresponding “energy landscape”, very often myriads of minima, each of them corresponding to a stable configuration of the nuclei.

He loves to paint, see the chekia paintings. These were seminal theoretical developments never before attempted for any molecule. In fact all of these attempts kwwntowa on some smoothing of the energy landscape.

S15, L. The multipole expansion has kwanhowa used in the intermolecular inter action theory, but Piela applied it for the first time to a single molecule. In all other methods the target function the hypersurface was kept intact. Any theory of regular polymers i.

The long-range forces in molecules and polymers Any theory of regular polymers i. His brave fight with the kwantosa lasted for over one year. His work in this area, which pointed out the importance of many-body effects, is fully appreciated only now when new information on many-body forces became cgemia from spectroscopy. Piela Delta 7, 3 L. He was also one of the pioneers in the field of ab initio studies of the nonadditivity of intermolecular forces.

He is missed very much not only as a scientific and moral authority, but also for his wonderful personality and warmth. Professor Piela serving as a peila of the Chemistry Department of the University of Warsaw has introduced profound changes pidla in L. According to that hypothesis some donor-acceptor oligomers may exhibit long-living isomeric electronic metastable states. Professor Piela has shown that all equations that emerge in the global optimisation procedures based on these phenomena are particular cases of a more general mathematical scheme [L.
