Effects of Mo,Nb,Ti on mechanical properties and corrosion resistance of 22.5%Cr ferritic stainless steel were investigated.The results show that Mo exists in ferritic stainless steel mainly in a solution state,and it can enhance steel's strength through solid-solution strengthening.In Ti/Nb dual-stabilized ferritic s…
Przeprowadzono badania materialu porowatego, przeznaczonego na implanty ortopedyczne, wytworzonego metodą metalurgii proszkow ze stopu Ti13Nb13Zr. Proszki z badanego stopu uzyskano metodą rozpylania plazmowego. Otrzymano probki o otwartej porowatej strukturze, stopniu porowatości do 68% i średniej wielkości porow w pr…
Die Erde war kurz nach ihrer Geburt vor 4,54 Milliarden Jahren ein lebensfeindlicher rot glühender Feuerball. Das Sonnensystem war damals noch nicht so aufgeräumt wie heute, es hatte sich gerade erst aus einem Nebel aus Gas und Staub gebildet, und zwischen den jungen Planeten wimmelte es geradezu von weiteren Materiek…
The process of formation of silica shells around emulsion droplets was investigated. The 1 H-NMR spectroscopy was applied to follow the silica shell formation around emulsion droplets by hydrolysis and condensation of selected silanes in the emulsion system. (3- aminopropyl) triethoxysilane (APS) and dimethyloctadecyl…
This study is about a heating line that uses thermal oil. It is located in a facility that produces interlayers used in cars windshields. A plastic resin is melted and is sent to a matrix called DIE where the interlayers are produced. The DIE needs to receive heat from the circulation of thermal oil in four different…
建立了顶空固相微萃取（HS-SPME）／气相色谱-质谱（GC-MS）同时测定液态化妆品中8种邻苯二甲酸酯类增塑剂（PAEs）的分析方法，并对萃取涂层、萃取温度、搅拌速率、盐浓度等参数进行了优化。最终采用65μm聚：二甲基硅氧烷／二乙烯基苯（PDMS／DVB）固相微萃取纤维头，调节待萃取液盐浓度为360g·L^-1，在搅拌速率600r／min及萃取温度90℃条件下萃取60min，在250℃进样口解吸4rain后供GC-MS分析。结果表明，该方法对除邻苯二甲酸二苯酯（DPhP）外的7种目标化合物的线性范围为10-2000μg·kg，检出限为0．7-13．6μg·kg^-1，回收率为83％-97％，相对标准偏差（RSD）为2．5％-10…

Lodz University of Technology, Faculty of Material Technologies and Textile Design, Department of Fibre Physics and Textile Metrology, ul. Żeromskiego 116, 90-924 Łodź, Poland Abstract This article presents the influence of the formation temperature of nonwovens from biodegradable aliphatic polyesters (trade name Bion…
The effects of noble metal (NM) promotion and deposition order (co-deposition of NM with the final Co deposition [co-dep] or sequential deposition of NM after Co deposition [seq-dep]) on surface area, pore size, metal retention, crystallite size, noble metal distribution and bonding in Co Fischer Tropsch (FT) catalyst…
This article introduces straightforward techniques for modeling, identification and\ninversion of a class of hysteretic systems. The assumed model structure consists of the parametric\nhysteresis operator and an input or output shaping function. The parametric hysteresis operator\nisolates the most general multi-value…
This thesis details an investigation into two regimes of charge transport where the behavior of the charge carriers is determined by quantum mechanical effects.An educational laboratory apparatus has been created to investigate small length scales comparable to the de Broglie wavelength of the electron, and display oc…
Quantum Dot Infrared Photodetector (QDIP) Focal Plane Arrays (FPAs) have been proposed as an alternative technology for the 3rd generation FPAs. QDIPs are emerging as a competitive technology for infrared detection and imaging especially in the midwave infrared (MWIR) and longwave infrared (LWIR) regime. These detecto…
Szybkośc korozji zbrojenia w konstrukcjach poddanych wplywom czynnikow atmosferycznych jest zmienna w czasie. Dotychczasowe proby modelowania tego parametru w funkcji temperatury i wilgotności powietrza oraz zawartości jonow chlorkowych w betonie uwzglednialy wszystkie te czynniki jednocześnie [1–3]. Takie podejście m…
Purpose: The main aim of this paper is investigation of the microstructure and thermal properties of selected Fe-Co-B-Si-Nb bulk amorphous alloy. Design/methodology/approach: The studies were performed on Fe-Co-B-Si-Nb alloy in form of rods with diameter of o=1.5 and o=2 mm. Master alloy ingot with compositions of Fe3…
The dissertation consists of three parts: Hermite methods, scattering from a lossless sphere, and analysis of supercontinuum generation. Hermite methods are a new class of arbitrary order algorithms to solve partial differential equations (PDE). In the first chapter, we discuss the fundamentals of Hermite methods in g…
Fibre reinforced composite materials are quite rightfully accused of suffering from poor out-of-plane mechanical properties, and delamination concerns are known to strongly reduce their competitive ...
ITER [10] is the first reactor relevant experiment of the tokamak configuration based on deuterium-tritium nuclear fusion reactions. It is a very challenging, scientific and technologically demanding as well as complex project, carried out in the frame of a very broad international collaboration, presently involving s…
The envelope method was employed to determine optical constants of thin films of TiO 2 and TiO 2 : Mn produced by electron-beam evaporation in a vacuum. The effect of thermal treatment on the optical properties of thin films was investigated
The real-time metabolic transformation of lactate in the mouse head was monitored following the injection of hyperpolarized 1-13C lactate at physiological doses. The results were compared with metabolic studies performed with hyperpolarized 1-13C pyruvate at similar blood concentration. From the observation that the l…
Streszczenie. Transformator blokowy najcześciej jest polączony bezpośrednio z generatorem synchronicznym. Na uzwojenia transformatora dzialają wszelkie zaburzenia, tak od strony od strony generatora jak i systemu elektroenergetycznego. W artykule wymieniono rodzaje mozliwych zaburzen i podano przyklad jednej awarii tr…
