Chalcogenides were studied since long time due to their important applications in photonics, ultrafast switching, ultra-high-density phase-change storage and memories, integrated fibre optics, biosensors, etc.[1]. Recently, we showed that LDI TOFMS is useful for the partial structure characterization [2-3]. However, t…
Tato disertační práce se zabývá přípravou a charakterizací tenkých vrstev chalkogenidových skel As30S70, As30S45Se25, Ge25S75 a Ge20Sb5S75 deponovaných z jejich roztoků metodou spin-coating. Byl studován vliv temperace a expozice elektromagnetickým zářením na jejich optické vlastnosti, strukturu a chemickou odolnost.…
Lanthanide-based complexes play a significant role in biological applications, spanning MRI contrast agents to molecular luminescent tags. Regardless of their application, these complexes should conform to general requirements, such as high stability against decomplexation at physiologically relevant conditions and su…
Intermetallic Metallic Compounds (IMCs) formation is a common cause for wire bond failures. This research studied the effect of US vibration duration on IMC formation and growth in Copper-Aluminum (Cu-Al) wire bonded samples. Wire bonded samples, using 2.5 mil (63.5 μm) thick Palladium coated Copper wire, is ultrasoni…
O APL de Pedras, Gemas e Joias tem como polo o Municipio de Soledade,RS Brasil — a “capital das pedras preciosas”, com atuacao voltada para o beneficiamento industrial e a comercializacao de gemas coradas, contemplando os pequenos artesanatos e alguma producao mais sofisticada. O APL e economicamente reconhecido como…
The article focuses on the procedure for exemption of the sealed and unsealed radionuclide sources of gamma radiation from regulatory control. The contradictory nature of the existing set of exemption criteria has been noted, leading, in some cases, to paradoxical situations. It is shown that the exempt activity value…
La polimerizacion de alquilfenoles ha sido objeto de varios estudios. Sin embargo algunos aspectos del mecanismo de reaccion permanecen desconocidos. De hecho, esta clase de polimeros conjugados presentan una estructura electronica muy interesante que hace que tengan campos de aplicacion muy diversos, especialmente cu…
In this work potentials of carbon nanomaterials calculated with Density Functional Theory (DFT) are approximated using an Artificial Neural Network (ANN). Previous work in this field has focused on ...
Condensation and deposit formation in the NaCl-Na2SO4 system, an experimental and modeling study
Nanocomposite coatings consisting of nanocrystallites embedded in an amorphous matrix (nc-TiC/a-C:H) can be tailored to exhibit unusual combination of properties such as high hardness and modulus combined with low friction and wear. These coatings are usually deposited utilizing direct current magnetron sputtering (DC…
Kayu merupakan bahan yang paling banyak digunakan untuk keperluan kontruksi, seperti bangunan rumah, skruktur jembatan, perahu, kapal laut, rel kereta api, bahan baku kertas dan lain-lain. Pengolahan kayu selalu menghasilkan sisa proses pemotongan/gergajian dalam berbagai bentuk dan ukuran. Seperti serbuk kayu yang se…
Fabrication of silicon based micro-channels is typically a complex process involving multiple steps such as lithography, bonding, thin film deposition, etching, surface migration etc. We present a method for the fabrication of microchannels . insired by 2D material transferring techniques, we transfer a 100 nm thick s…
Pulsed laser deposition (PLD) of the CZTS absorber for thin solar cells with up to 5.
The marine diatom genusLeptocylindrusis a major component of phytoplankton blooms in coastal ecosystems worldwide, however, little is known about the ecology and meticulous species composition of this genus in the Adriatic Sea. Although Leptocylindrus danicus andL. minimus have been reported from numerous studies cond…
This Ph.D. thesis describes the research and ndings from experimental testing of a methanation catalyst and the characterisation of said catalyst. Methanation is the conversion of syngas (CO and H2) typically from coal or biomass to methane and water. Methane is the biggest constituent of natural gas and as the infras…
Одним из путей интенсификации проектной деятельности и автоматизации выполнения чертежно-графических работ является использование средств компьютерной графики. Среди них значительное место занимает программный комплекс автоматизации проектных работ AutoCAD фирмы AutoDESK, ставший международным стандартом для подготовк…
Carbon Capture Utilization and Storage (CCUS) is a promising technology for the reduction of CO2 emissions, e.g. from fossil-fuel operated power plants or cement mills. Crucial points for a sustainable and future-proof CCUS procedure are reliability and cost efficiency of the pipeline transport network. Due to the abs…
In the last decade, there has been a great interest in the phosphonic acid-based molecular complexes and coordination polymers. Because the M-O-P bonds are stronger then the M-O-C bonds in carboxylates, phosphonates are widely used in the synthesis of different metal-organic materials, such as polynuclear metal phosph…
Flow history of polymer melts in processing greatly influences the crystallinity and hence the solid properties of the final material. A wide range of polymer processes involve extensional flows e.g. fiber spinning, blow moulding etc. However, due to instrumental difficulties, experimental studies on polymer crystalli…
Gli autori del presente contributo, unendo competenze di tecnologia farmaceutica e di scienza e ingegneria dei polimeri, stanno portando avanti un lavoro dal carattere multidisciplinare volto alla messa a punto di nuovi sistemi per il rilascio modificato di farmaci (“drug delivery systems”, DDS). Si è considerato il…
