Guided waves for monitoring of plate structures with linear cracks of variable length
PublikacjaDamage occurring at the work of plate structures may grow to a considerable size. The joint action – the detection of a defect at the earliest possible stage, the monitoring of its growth and the determination of its critical size in the context of structural reliability allows optimizing the cost of the maintenance and repair of structural elements. Thus the development of monitoring systems for permanent observation of fault...

ATR FT-IR H2O spectra of acidic aqueous solutions. Insights about proton hydration
PublikacjaW artykule podjęto próbę ilościowej analizy widm oscylacyjnych H2O w wodnych roztworach kwasów. Widma H2O dostarczają głównie informacji o stanie strukturalnym cząsteczek wody, wynikającym ze sprzężeń oscylatorów w układzie. Są jednak znacznie trudniejsze w interpretacji niż widma HDO. Widma wodnych roztworów kwasów jednoprotonowych (HCl, HClO4, HPF6) zmierzono posługując się spektroskopią FT-IR w technice osłabionego wewnętrznego...
