Opis:
Warstwy diamentopodobne osadzano na powierzchni stali austenitycznej 316L na układzie lasera ekscymerowego typu ArF (λ = 193 nm). Proces wytwarzania warstwy azotowanej oraz warstw z węgla amorficznego następował dwuetapowo w jednej komorze eksperymentalnej. Przeprowadzone badania miały na celu osadzenie warstw diamentopodobnych z możliwie dużą zawartością fazy sp3. Określenie struktury fazowej osadzonych warstw wykonano za pomocą spektrometru fourierowskiego w podczerwieni (FTIR), a struktura powierzchniowa została zwizualizowana na mikroskopie sił atomowych (AFM).
The amorphous carbon films were deposited onto 316L stainless steel by using the laser excimer (λ = 193 nm). Deposition of nitrided layers and amorphous carbon films was executed in two stages in one experimental chamber. The aim of the experimental investigations was to obtain diamond like carbon films with a high quantity of sp3 phase. Phase analysis of deposited films was made by using a Fourier transform infrared spectrosmetry (FTIR). The surface topography was investigated and vizualized by atomic force microscopy (AFM).

Opis:
The article presents preliminary results of investigation on structure, morphology and mechanical properties of boron nitride thin films prepared by pulsed laser deposition on various steel substrates. In order to improve adhesion and reduce internal stresses, substrates were subjected to gas nitriding. To increase gas ionization in the chamber and provide the deposited particles with higher energy RF discharge generator was used. Structure and morphology of coatings were examined by atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR). Mechanical properties like nanohardness (sclerometric) and elastic modulus (using approach curves) were characterized by UNMT. Adhesion of coatings was measured by scratch tests; critical load was determined on the basis of microscopic observation and friction force and acoustic emission runs. On the basis of obtained results, possibility of using steel as substrate for BN thin films deposition was confirmed. Stable, crystalline, multiphase coatings with good adhesion to the steel substrate were obtained. It was also proved that mechanical properties of prepared coatings and their adhesion to the substrates strongly depend on the type of the substrate. In the next stage tribological properties of BN, coatings will be examined in particular in terms of wear resistance and friction coefficient between coatings and steel.

Opis:
Warstwy hydroksyapatytu [wzór] zostały osadzone na podłożu Ti6Al4V metodą laserowej ablacji (PLD), przy użyciu lasera ekscymerowego ArF. W celu ustalenia wpływu temperatury podłoża na strukturę osadzonych warstw, proces osadzania przeprowadzono dla zakresu temperatur podłoża od 150 stopni Celsjusza do 650 stopni Celsjusza. Analiza fazowa osadzonych warstw została przeprowadzona przy użyciu Fourierowskiej spektrometrii podczerwieni (FTIR). Topografia otrzymanych warstw charakteryzowana była metodą mikroskopii sił atomowych (AFM). Otrzymane wyniki wskazują na zależność struktury osadzonych warstw oraz ich morfologii od temperatury podłoża.
Hydroxyapatite layers [formula] were deposited on Ti6Al4V substrate by use of pulsed laser deposition (PLD) technique using ArF excimer laser. In order to determine the influence of substrate temperature on structure of deposited films the experiment was performed for substrate temperatures ranged from 150 degrees of Celsius to 650 degrees of Celsius. The chemical analysis of deposited hydroxyapatite coatings were performed by Fourier Transform Infrared spectroscopy (FTIR). The morphology of deposited layers were characterized by means of Atomic Force Microscopy (AFM) method. The results indicate dependence of apatite structure and surface morphology on the substrate temperature.

Opis:
Warstwy z hydroksyapatytu osadzane były na podłożu ze stopu Ti6Al4V z warstwą buforową TiN metodą laserowej ablacji. Dwie tabletki składające się ze sprasowanego hydroksyapatytu [wzór] i domieszkowanego magnezem hydroksyapatytu [wzór] zostały poddane ablacji laserem ekscymerowym ArF (lambda=193 nm). Użycie materiałów o różnym składzie umożliwiło ustalenie wpływu składu chemicznego tarczy na strukturę osadzanej warstwy. Uzyskane warstwy były analizowane za pomocą metody dyfraktometrii rentgenowskiej (XRD). Wyniki analizy XRD pokazują, że osadzona warstwa z hydroksyapatytu domieszkowanego magnezem posiada strukturę polikrystaliczną w przeciwieństwie do struktury warstwy osadzonej z czystego hydroksyapatytu, która była amorficzna.
Hydroxyapatite layers were deposited on Ti6Al4V substrates with TiN buffer layers by use of pulsed laser deposition method. With this technique two pressed pellets consisted of hydroxyapatite [formula] and hydroxyapatite doped with magnesium [formula] were ablated using ArF excimer laser (lambda=193 nm). The use of different targets enabled to determine the influence of target composition on the nature of deposited layers. The obtained deposits were characterized by means of X-ray diffraction method (XRD). The analysis from XRD showed that Mg-doped HA layer had crystalline structure and composition of layer deposited from pure HA material is characterized by amorphous nature.

Opis:
W pracy omówiono system pomiarowy, który jest przeznaczony do badań kwantowych laserów kaskadowych. Lasery te stanowią kolejny etap w rozwoju technik optoelektronicznych związanych np. ze spektroskopią lub łącznością optyczną w otwartej przestrzeni. Istotnymi elementami pracy są zaimplementowane procedury wyznaczenia parametrów laserów np. sprawności czy temperatur charakterystycznych. W części eksperymentalnej przedstawiono wyniki badań przykładowego lasera firmy Alpes Lasers S.A.
Quantum cascade lasers (QC lasers) are very promising radiation sources in some optoelectronic techniques operating at the infrared and THz spectra. The lasers can be applied in many science areas and life fields e.g. spectroscopy or free-space optical communications. Progress in QC lasers technology contributes to the continuous improvement of their performances. But this developing process also requires the testing of each laser structure. One of the most important research tasks was to measure temperature characteristics of the light-current-voltage and to determine the threshold current, the slope efficiency or characteristic temperatures. The paper presents a measurement system for investigating some QC laser parameters using specialized equipment such as: a precision current driver,a temperature controller with laser housing, an optical power meter and a detection module (Fig. 4). Important features of the system are the implemented procedures for pulse shape acquisition and determination of the main performance of QC lasers. There are also listed the main requirements for both ranges and methodologies of the measured signals. Using a resistor and a laser diode (650 nm), preliminary studies were performed to verify operation of the measuring system (Figs. 5 and 6). In the main part of the paper the measurements results of the QC laser sample produced by Alpes Lasers SA are presented (Fig. 7). In the conclusions a brief description of the system performances and directions for its further development are given.

Opis:
Carbon thin films are often called in the literature, "diamond-like carbon" films. They consist of two basic allotropic forms of carbon, which are graphite and diamond. Carbon atoms with $sp^{2}$ bonds form after deposition of a graphite-like phase. Atoms with $sp^{3}$ bonds form a diamond-like phase. Diamond-like crystallites are built into a graphite-like phase matrix. In this paper there are presented experimental results of deposition of carbon films by the magnetron sputtering method and the results of analysis of the surface and phase structures of the deposited films. The amorphous carbon films were deposited from graphite targets on 316L steel substrates. The films were deposited at room temperature, in vacuum. The deposition time was 3 h; the depositions were conducted at two different distances between the substrate and the magnetron target.

Opis:
W artykule przedstawiono prace dotyczące optoelektronicznych sensorów gazów oraz osiągnięcia własne w zakresie wykrywania tlenków azotu (NOx). W sensorach do wykrywania NOx zastosowano polskie lasery emitujące promieniowanie o długości fali 410 nm oraz nowoczesne kwantowe lasery kaskadowe na zakres podczerwieni. Opracowane sensory charakteryzują się czułością graniczną na poziomie ppb i mogą być zastosowane do monitoringu zanieczyszczeń atmosfery, wykrywania materiałów wybuchowych oraz w diagnostyce chorób.
The paper presents an overview of a few optoelectronic technologies for gases detection. Two sensors of nitrogen oxides (NOx) are also described. In the sensors the cavity enhanced absorption spectroscopy was applied. It is characterized by a very good sensitivity and selectivity of the detection process. The main aspect of its operation bases on absorption of the light by specific compounds. The identification of the matter is determined by spectral matching of the two spectra: optical radiation and absorption lines of species of interest. In contrast to the remote detection methods, the measurements are made at the place of sampling. Polish laser diodes and modern quantum cascade lasers were used there. Laser emission wavelengths were located in the visible (410 nm) and infrared range. The detection limit of ppb level was achieved. Due to that, they can be successfully applied to monitoring of atmospheric pollution, explosives detection and in diseases diagnosis. The preliminary studies using the developed sensors showed that it was possible to detect explosives such as TNT, PETN, RDX, HMX at the level of ng. Additionally, there is also discussed application of sensors to analysis of the exhaled air. This will be particularly useful for: the early detection of a disease, the monitoring of the therapy, the monitoring of the greenhouse exogenous (bacterial emissions or toxins), or the analysis of metabolic gases.

Results of investigations into integration of foam titanium implants (FTI), with rabbit bone are presented. Three groups of implants were examined: clean titanium implants produced by selective laser melting, FTI coated with a thin film of octacalcium phosphate (OCP), doped with 0.6 weight percent of Mg, deposited by pulsed laser deposition (PLD), and FTI with hydroxyapatite (HA) doped with 0.6 wt.% of Mg. Analysis of histopathology of implants' integration with bone were performed by staining using the triple chromatographic method of Masson - Goldner, pla- nimetric analysis using the Kruskal - Wallis test, an ANOVA test and microtomography. The best results were obtained for implants coated with HA, followed by those coated with OCP. Implants from these two groups showed superior integration with bone than uncoated titanium implants.

Hydroxyapatite and bioglasses are important bioactive materials as they exhibit direct bonding with human bone. Therefore they are used as coatings for metallic implants. The aim of the present study was to compare two types of layers: monophase hydroxyapatite (HA) and composite-type HA+BG hydroxyapatite mixed with bioglass (BG) (BG 50% of weight) during the initial stage of their interaction with cell medium. In vitro studies were performed in order to determine the effect of the investigated layers on cell response. After 3 and 7 days the behaviour of the cells grown on the above surfaces was estimated through determination of the cell adhesion (CV colorimetric assay). Cell morphology and properties of biomaterials surfaces were analysed by atomic force microscopy (AFM).

Opis:
The paper presents the results of the structure investigation of a counter electrode in dye-sensitized solar cells using the carbon nanomaterials. Solar cells were fabricated on the glass with transparent conductive oxide TCO (10Ω/sq). Nanocrystalline titania based photoanode was prepared by spreading TiO2 paste onto TCO glass and subsequently annealed at 450°C for at least 30 min to convert anatase phase and make an interparticle network. After then the nanostructured titania films was immersed into an ethanolic solution of the ruthenium-based dye. As a counter electrodes of dye-sensitized solar cells composite films of carbon nanomaterials and polystyrene sulfonate doped poly (3,4-ethylenedioxythiophene) PEDOT-PSS (Sigma-Aldrich) were deposited onto TCO substrates. Because carbon nanoelements and titanium oxide consist of nano-metric structural units to determine the properties of the cells and their parameters several surface sensitive techniques and methods, i.e. Raman spectroscopy, Scanning Electron Microscopy (SEM), High-Resolution Transmission Electron Microscopy (HRTEM), and electric properties of conductive layers were used.

Opis:
The influence of the carbon nanotubes counter electrode deposited on the FTO glass substrates on the structure and optoelectrical properties of dye-sensitized solar cells counter electrode (CE) was analysed. Carbon materials have been applied in DSSC s in order to produce low-cost solar cells with reasonable efficiency. Platinum is a preferred material for the counter electrode because of its high conductivity and catalytic activity. However, the costs of manufacturing of the platinum counter electrode limit its use to large-scale applications in solar cells. This paper presents the results of examining the structure and properties of the studied layers, defining optical properties of conductive layers and electrical properties of dye-sensitized solar cells manufactured with the use of carbon nanotubes. Such counter electrodes are promising for the future fabrication of stable, low-cost and effective dye-sensitized solar cells.
