In this work we analyze how a form of zinc oxide (ZnO) nanomaterials determines their electrochemical properties. Different forms of ZnO were compared: tetrapods, nanoparticles and nanowires. ZnO tetrapods synthesized in our laboratory were found to have better electrochemical properties than commercial ZnO (nanoparticles, nanowires). ZnO tetrapods have the highest active surface area (A = A= 0.095 cm2), and the lowest number of electronic transport skaičiaus (DEp = 61.7 mV), which is very close to the theoretical value. This detailed study of the influence of ZnO nanostructure and form on electrochemical properties, will be useful in the development of future biosensors.


Mindaugas Juodėnas, Domantas Peckus, Tomas Tamulevičius, Yusuke Yamauchi, Sigitas Tamulevičius, and Joel Henzie, Effect of Ag Nanocube Optomechanical Modes on Plasmonic Surface Lattice Resonances (2020). ACS Photonics

This article describes the interaction of ultrafast light pulses with silver nanoparticles and their arrays. We showed that light pulses elapsing a trillionth of a second (1/1 000 000 000 000 s) can excite mechanical vibrations in nanoparticles that are a thousand times smaller than the width of a human hair. These processes can be visualized in dynamic light absorption spectra because the color of plasmonic materials depends on their size and shape which can be modulated by mechanical vibrations. We investigated arrays of such nanoparticles and described the influence of local ultrafast oscillations on a long-range phenomenon—the surface lattice resonance (a collective optical response of regular nanoparticle arrays), which is extremely sensitive to the color of light scattered by the nanoparticles. Our observations will allow to create ultrafast elements of nanophotonics and opens the doors for a new generation of nanolasers.

This paper describes the results of studies of diamond-like carbon coatings (coatings containing carbon atoms of different spatial configurations – typical for crystalline diamond and graphite) with different concentrations of aluminum nanoparticles (DLC:Al). We investigated two different types of magnetron sputtering deposited DLC coatings: hydrogenated (coatings also contain hydrogen atoms) and non-hydrogenated with different Al atomic concentrations in them. If the studies of the composition of hydrogenated DLC:Al did not show unexpected results – alumina (AlOx) derivatives were formed in these coatings, then in addition to AlOx compounds, aluminum carbide (AlCx) derivatives were formed in non-hydrogenated DLC:Al. It is known that the formation of AlCx is usually very inefficient and requires temperatures above 1000 oC, therefore most often during synthesis, which takes place at much lower temperatures (e.g. room temperature), no AlCx is formed in DLC:Al films. The fact that we were able to obtain AlCx at relatively very low room temperatures is an interesting result, and the better understanding of the synthesis method we used may contribute to the efficient preparation of AlCx coatings in the future. Thanks to their high thermal conductivity, low thermal expansion and high refractive index, these coatings can be widely applied in optoelectronics. The sufficiently simple magnetron-based coating preparation method described in the article may contribute to the wide practical applications of AlCx in the future.

Herein, photothermal modification of nanocomposite films consisting of hydrated vanadium pentoxide (V2O5·nH2O) nanoribbons wrapped with graphene oxide (GO) flakes was performed via 405 nm direct laser irradiation. The combination of X-ray diffraction, X-ray photoelectron spectroscopy, Raman scattering, transmission electron microscopy, and scanning electron microscopy allowed comprehensive characterization of physical and chemical changes of GO/V2O5·nH2O nanocomposite films upon photothermal modification. The modified nanocomposite films exhibited porous surface morphology (17.27 m2 g–1) consisting of randomly distributed pillarlike protrusions. The photothermal modification process of GO/V2O5·nH2O enhanced the electrical conductivity of nanocomposite from 1.6 to 6.8 S/m. It was also determined that the direct laser irradiation of GO/V2O5·nH2O resulted in considerable decrease of C–O bounds as well as O–H functional groups with an increase of the laser power density.

This paper reports on the properties of scratch-healing thiol-ene coatings synthesized at the Institute of Materials Science at Kaunas University of Technology on the basis of photopolymerizable composition prepared as a mixture of pentaerythritol tetrakis(3-mercaptopropionate) (PETMP) and 1,3,5-triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione (TTT), with 1 wt. % of 2,2-dimethoxy-2-phenylacetophenone (DMPA) photoinitiator. It was demonstrated that such coatings exhibit high optical transparency, elasticity and shape-memory. The crosslinked PETMP-TTT polymer network was capable to initiate scratch recovery not only under the influence of an external stimulus but also at the room conditions. It was suggested that such coatings could be integrated in a new generation of the optoelectronic products.


Mindaugas Juodėnas, Tomas Tamulevičius, Joel Henzie, Donats Erts, and Sigitas Tamulevičius, Surface Lattice Resonances in Self-Assembled Arrays of Monodisperse Ag Cuboctahedra (2019). ACS Nano

This article describes a new optical phenomenon—a surface lattice resonance (a collective optical response of regular nanoparticle arrays) and a method to produce the required plasmonic nanostructures using capillary force-assisted nanoparticle assembly. We showed that this extremely wavelength-sensitive phenomenon can be generated by arranging noble metal (gold, silver) nanoparticles on specifically patterned templates. Our method avoids serial writing of individual nanoparticles by using self-assembly to arrange them en masse from a colloidal solution. These surface lattice resonance-featuring nanostructures allow to manipulate light and enhance the electric field both locally and throughout the plane of the array, which is essential for extra-sensitive biosensors and nanolasers.

Giant Negative Piezoresistive Effect in Diamond-like Carbon and Diamond-like Carbon-Based Nickel Nanocomposite Films Deposited by Reactive Magnetron Sputtering of Ni Target (2018). ACS Appl. Mater. Interfaces

A giant negative piezoresistive effect (change in the electrical resistivity of material when mechanical strain is applied ) was observed for hydrogenated diamond-like carbon (DLC) and DLC-based nickel nanocomposite (DLC:Ni) films. The observed relative change in resistance was at least 30 times larger than for monocrystalline silicon, the most often used piezoresistive material. This effect in the DLC films deposited by either reactive high-power impulse magnetron sputtering or direct current magnetron sputtering of Ni target was explained by possible clustering of the sp2-bonded carbon and/or areas with the decreased hydrogen content. These results open the path towards the novel, very precise sensors.

Thin solid films

We observed that diamond like carbon coatings with copper nanoparticles deposited by reactive magnetron sputtering were characterized by a layered structure. Apparently, this layered structure (nanometer-sized areas with higher concentration copper either amorphous carbon) is visible in transmission electron microscopy images. In this work we have shown that such a structure can be observed and studied using non-destructive methods – X-ray reflectometry and spectroscopic ellipsometry. We have demonstrated that after selecting the appropriate models the structure determined by these indirect methods is in many cases perfectly compatible with the direct electron microscopy and microanalysis studies. Thus, for the first time in this article, the possibilities of these methods in the analysis of nanolayered coatings were described, revealing the limits and advantages of each of the methods.

Carbon

Polymeric carbon nitride (p-CN) was produced using a two-step thermal treatment process of urea without tailoring the reaction pressure and atmosphere. A systematic analytical analysis employing X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Raman scattering and X-ray diffraction (XRD) was performed for structural and chemical characterization of p-CN. Thermal vacuum deposition of thin films (C3N) from p-CN powder was performed, followed by characterization of corresponding structural, chemical and photophysical properties. The atomic force microscopy analysis of these films revealed sheet-like structural fragments distributed along the surface. The C3N thin films were found to be amorphous as determined from XRD. It was demonstrated that C3N can be used as a functional layer for optoelectronic devices.
