SiO2 nanocolumns as spacers are introduced into plasmonic antireflective structure by oblique angle deposition. The deposition angles determine the morphology of SiO2 and the size distributions of Ag particles, which results in different reflections.
Industrial development and contemporary life style led to spread a large amount of non-biodegradable plastic waste. This paper aims to study the effects of recycling polyethylene terephthalate (PET) plastic waste which is a type of disposable plastic packaging waste as an asphalt modifier, to create a sustainable asph…
In this study, gold nanostars with controllable branchlengths were synthesized. The potential use of these nanostars in detection applications and analysis of living cells based on SERS were also investigated.
Simulaatioita ja numeerista analyysia käytetään yhä enenevässä määrin osana suunnitteluprosessia. Simulaatiot ja virtuaaliset prototyypit mahdollistavat nopeamman suunnitteluprosessin ratkaisujen iteroinnin, eritoten jos simulaatioiden hyödyntäminen aloitetaan jo varhaisessa vaiheessa suunnittelua. Tällöin simulaatioi…
Tensile, swelling and morphological properties of bentonite filled acrylonitrile butadiene rubber (NBR/Bt) composites were studied. The experiments were conducted at room temperature by using two rolled mill, universal testing machine (INSTRON), and American Standard Testing Method (ASTM) D471 for compounding, tensile…

Here, we described a bottom-up approach for the reconstitution of three-dimensional blood vessel model tissues for the application of in vitro design of nanomaterials. Nanomaterials have been widely used for applications in biomedical fields and could become an indispensable in the near future. However since it is dif…
Abstract. In order to analyze the drying characteristics of loofah, obtaining the optimal drying conditions. In this paper, the effects of different slice thickness and different temperature on the vacuum pulsation drying characteristics of loofah were studied by vacuum pulsation drying method. The drying kinetics of…

The acid-base chemistry that drives catalysis in pyridoxal-5'-phosphate (PLP)-dependent enzymes has been the subject of intense interest and investigation since the initial identification of its role as cofactor in this extensive class of enzymes. X-ray crystallography, optical spectroscopy, and physical-organic studi…
We report highly efficient perovskite LEDs enabled through the formation of self-assembled, nanometer-sized crystallites. The external quantum efficiency reached 10.4% for CH3NH3PbI3-based LEDs and 9.3% for CH3NH3PbBr3-based LEDs.
Intumescent coatings are used for decades to increase the fire resistance of steel or wood constructions. Intermediate and full scale tests are used to assess their protection performance. For the product development and screening, cheaper and faster bench-scale tests are demanded that provide information about therma…
Much interest exists in alkaline exchange membrane (AEM) fuel cells, not just because of the higher efficiency for the oxygen reduction reaction (ORR) under alkaline conditions, but also because of their inexpensiveness due to the possibility of using low-cost materials, such as non-platinum-group catalysts. Due to th…
The wear rates of self-mated alumina couples show that friction as well as wear is largely determined by the above mentioned hydro-thermal conditions. The presence of water and its amount available in the surrounding system either in liquid or in gaseous form plays a key role for friction and wear behavior and can be…
The article considers the ways of improvement of designs of overlappings slightly deepened underpasses. The proposed new design solution for precast-monolithic slabs slightly deepened underground pedestrian crossings with the lower vaulted surface is made on a permanent form of arched profiled flooring. The evaluation…
Le munizioni perforanti (AP - Armor-Piercing Ammunition) sono una tipologia di proiettili impiegati allo scopo di perforare protezioni balistiche (armature o schermi difensivi) e sono generalmente costituite da un penetratore contenuto in un involucro (jaket). All'impatto tale involucro si distrugge, permettendo l'ava…
Der Fortschritt geschieht heute so schnell, dass, während jemand eine Sache für gänzlich undurchführbar erklärt, er von einem anderen unterbrochen wird, der sie schon realisiert hat."
A spinel crystal structure of ZnFe2O4 was synthesized by using the spray pyrolysis method. A pure phase ZnFe2O4 was obtained at a relatively lower temperature of 400°C. The gas sensing properties of the ZnFe2O4 films with different volume % of Zn and Fe were measured at different temperatures. The maximum ethanol gas…
Quantitative investigations of hydrogen dependent properties of aircraft landing gear materials have only scarcely been carried out in the past. They are essential for respective component life time assessments. To better understand the behavior of these landing gear materials in a hydrogen rich environment, specimens…
Fischer-Tropsch synthesis over supported cobalt catalysts is an important industrial process for the conversion of synthesis gas to hydrocarbons. Although enormous efforts have yet been devoted to understand the fundamental aspects of the Fischer-Tropsch synthesis, the influence of the support structure still remains…
