Multi-responsive polymers have gained a lot of attention, mainly due to the huge array of applications [1] they can be used for, such as sensors, drug delivery systems or tissue engineering. In this work, core-shell micelles with a pH-responsive shell, whose shell blocks undergo a phase transition from expanded to collapsed as a response to changes on the pH, are investigated. At higher...

The fabrication of ReBa2Cu3O7-δ (Re: rare earth element) (ReBCO) high temperature superconductor (HTS) based coated conductors requires development of intermediate layers between a metal tape and a superconductor which are called buffer layers. These buffer layers have to fulfill a list of requirements among which are chemical stability and compatibility with adjacent films. Inclined substrate...

Pump-probe electron diffraction and microscopy with ultrashort electron pulses allow directly observing the atoms and charges in motion on their fundamental length and time scales (picometers and femtoseconds/attoseconds). Such imaging is essential for understanding light-matter interaction from a fundamental perspective. My current research group has developed an all-optical control approach...

Shape memory alloys (SMA) are stimuli-responsive materials which have the ability to return to their original shape and size after induced deformation. Ni-Ti (nitinol) is a SMA which presents several interesting properties for engineering applications, such as shape memory effect (SME) and superelasticity (SE). In both effects, the Ni-Ti deformation occurs by a diffusionless martensitic phase...

Crystallography and diffraction experiments with bright radiation sources offer much more that a structure solution and refinement. Structural data collected as function of pressure, temperature, electric or magnetic field, under laser radiation or in any other in-situ conditions provide with a unique information on the thermodynamics of various processes in solids. In the lecture I...

Since solar energy is the most abundant and sustainable reservoir of energy on earth, there is a tremendous scientific effort to find an efficient way for it to substitute our strong dependency on fossil energy. This is where photocatalytic reactions such as hydrogen/oxygen evolution reaction (Photo Water Splitting) have shown important improvements and hold great expectation. The efficient...

Charge transfer materials are bi-stable systems where an external stimulus that can be provided by temperature, pressure or light is capable to induce an electron transfer between two metallic atoms. The resulting change in the electronic configuration can alter the electrical, magnetic and optical properties of these materials. The use of light to trigger these changes is particularly...

In the last decade, iridium oxides (iridates) have been heavily studied due to their unexpected cor- related behavior induced by the strong spin-orbit coupling (SOC) and crystal field. Their novel ground state arises from the superposition of the Ir outermost orbitals and is often referred to as jeff =1/2 state. Recently, Birol and Haule[1] predicted the realization of...

Electrically driven III – V semiconductor nanowires (NWs) are wildly considered to be a potential frontier in small and coherent light sources for photonic integrated circuits. One of most essential characters of semiconductor nanowires is that its active mediums of lasing are surrounding by dielectric shells which forming an innate optical cavity and waveguide due to 1-D geometry. However,...

The history of x-ray physics at University of Helsinki, Finland, dates back to the 1960's when systematic x-ray crystallographic studies were started at the Department of Physics. In the 1970's, x-ray Compton scattering spectroscopy [1] was introduced, then using the home-lab based x-ray sources. Synchrotron radiation use in Helsinki started already in the 1970's since the work of prof. Pekka...
