Lamb wave propagation in a single lap adhesive joint
PublikacjaThe aim of the paper is the analysis of Lamb wave propagation in adhesive joints. The research was performed on a single lap adhesive joint of two steel plates. Two types of joints, namely an intact and with defect were considered. In experimental investigations the condition assessment of the joint was performed with the use of antisymmetric Lamb waves excited by a plate piezo actuators and measured by a laser vibrometer. Numeri-cal...

Ethylene decomposition on TiO2 - UV and Fluorescence lamp
Dane BadawczeData contain chromatograms recorded during decomposition of ethylene flowing over TiO2 through the quartz tubular shape reactor. TiO2 was coated onto glass plates with dimension of 2cmx2cm, in total 3 plates were used and placed inside reactor. Reactor was irradiated by UV (Special 'TL'E, Philips) or fluorescent (Lumilux, OSRAM) 3 ring-shaped lamps,...

Wymiana lamp sodowych wysokoprężnych na lampy ledowe – aspekty techniczne i ekonomiczne modernizacji oświetlenia dróg
PublikacjaPrzedstawiono zasady projektowania oświetlenia dróg zgodnie z aktualnymi normami. Wykonano uproszczone projekty oświetlenia dwóch rodzajów dróg i na ich przykładzie porównano parametry techniczne lamp ledowych i lamp sodowych wysokoprężnych. Zwrócono uwagę na odkształcenie prądu pobieranego przez te lampy. Wykonano analizę ekonomiczną pozwalającą ocenić opłacalność stosowania lamp ledowych.

Lamb wave-based monitoring of shear failure of an adhesive lap joint
PublikacjaThe paper presents a study on the elastic wave propagation in adhesive joints of steel plates subjected to tensile loading. A single lap joint was chosen for analysis because of its simplicity and plurality of applications. Experimental investigations consisted of the uniaxial extension of prepared specimens. Force and displacement values were recorded by a testing machine. Simultaneously, guided Lamb waves were excited and signals...

Poly-L-Lysine-functionalized fluorescent diamond particles: pH triggered fluorescence enhancement via surface charge modulation
PublikacjaRecently, the interest in applying fluorescent diamond particles (FDPs) containing nitrogen-vacancy (NV) centers for enhancing the mechanical and chemical properties of some materials, biological imaging, and sensing has been expanding rapidly. The unique properties of NV centers such as intensive, time-stable fluorescence, and an electron spin, which exhibits long coherence time and may be manipulated using external stimuli, such...
