Tato bakalářská práce si klade za cíl popsat využití vybraných neželezných kovů pro zjemnění mikrostruktury oceli. V práci jsou uvedeny jak vlastnosti prospěšných neželezných prvků, tak i prvků v oceli škodlivých. Vznik intermetalických fází je dokumentován v přiložených rovnovážných diagramech Fe–NŽK. Ty nám znázorňu…
PLGA has been widely used as biomaterials in the pharmaceutical and medical applications. However the decomposition products of the PLGA are known to decrease the pH of surrounding tissue, thus causing inflammatory reaction. Moreover, it is required to improve mechanical and biological property of the materials to use…
Půda je heterogenni polydisperzni system, který vznika a vyviji se komplexnim působenim půdotvorných faktorů. Je složena z mineralni a organicke složky v různých formach. Je přirozeným prostředim velkeho množstvi mikroorganizmů, kteři se významně podili na půdotvorných procesech, rozkladu a synteze organických latek a…
Carbon nanotubes (CNTs) are hailed as being a "revolutionary super-material", with extensive scope of application, a highly promising one being in Organic Solar Cells (OSCs): ultrathin, ultralight and flexible solar cells with phenomenal applicability and potential. This led us to investigate: "What about their struct…
Tässä kandidaatintyössä lasketaan energiahyötysuhteet ja kustannusarviot kolmelle eriasteisesti jalostetulle puuperäiselle biopolttoaineelle. Työn tavoitteena on vertailla energiahyötysuhteiden ja tuotantokustannusten muuttumista jalostusvaiheiden välillä ja tällä tavoin selvittää jalostamisen energiataloudellista kan…

Determination of the Shape of a Flattening Filter Free (FFF) Radiation Beam When Modified by a Physical Wedge.The determination of a flattening filter free (FFF) beam profile when the collimator is intentionally modified to incorporate a physical wedge.Specifically, radiation beam profiles change shape when a metallic…
There are many various species of bamboo trees in Indonesia, one of which is Petung bamboo (Dendrocalamus Asper). Bamboo is one of the potential material as a substitute for steel reinforcement. This paper will discuss the model of bamboo reinforcement to increase the flexural capacity of concrete beams. The use of th…

Показан износ лезвий с ZrC-, ZrC-Ni-УДА-покрытиями ножей из карбида вольфрама твердых сплавов фрезерного инструмента при резании ламинированных древесностружечных плит (ДСтП). ZrС-покрытия формировались методом конденсации с ионной бомбардировкой. Композиционные Ni-УДА-покрытия были осаждены из сульфатно-хлоридных эле…
Dynamic Increase Factor (DIF) has been used to consider the compressive strength enhancement of concrete at the high and intermediate strain rates. However, DIF formulae suggested until now include the inertia effects as well as the rate effect because the DIF formulae has been assumed as a function of only the strain…
An increasingly interconnected world creates a high demand for high-density and low-cost data storage. Redox-based memristive devices, which allow switching between high and low electrical resistances through the application of voltages, are highly attractive candidates for next-generation non-volatile memory. But the…
Keratinocyte carcinomas (KCs) are the most common cancers globally. Ultraviolet light is the key risk factor for these cancers but sunscreen has proven ineffective in their prevention, indicating a need for new prophylactic agents. Chronic elevation of high molecular weight (HMW) tissue hyaluronan (HA) in skin is link…
Two-dimensional nanomaterials, such as graphene and phosphorene, has been attracting researchers’ interest, due to their possible applications. One of their applications is as gas sensors. Carbon dioxide is a gas, which needs to be monitored because it is one of the responsible for the greenhouse effect and for the ch…
Although magnesium alloys have been explored intensively for application as biodegradable metal implants, there is lack of understanding of the biological response to its corrosion products and the correlation between corrosion behaviour and local tissue repair process at the implantation site. The aim of the study wa…
Hybrid powder-suspension Al2O3-ZrO2 coatings by axial plasma spraying: Processing, characteristics & tribological behavior
One of the main challenges in the development of graphene field-effect transistors (GFETs) forapplications in high frequency electronics is achieving high maximum frequency of oscillation (fmax),which is the power gain parameter. A promising way to achieve higher fmax is drain current saturationvia saturation of the c…
Pancreatic ductal adenocarcinoma (PDAC) is a notoriously lethal disease characterized by prominent stromal involvement, which plays complex roles in regulating tumor growth and therapeutic response. The extracellular matrix (ECM)-rich stroma has been implicated as a barrier to drug penetration, although stromal deplet…
At the catalytic interface, catalysts are represented by an ensemble of cluster isomers or surfaces, each of which may contribute to the system’s stability, activity, selectivity, and resistance to sintering or poisons by reaction byproducts. I use ab-initio methods in conjunction with statistical-mechanical arguments…
The thesis presents work regarding amphiphilic molecules associated in aqueous solution or at the liquid/solid interface. Two main topics are included: the temperature-dependent behavior of micelles and the adsorption of dispersants on carbon nanotube (CNT) surfaces. Various NMR methods were used to analyze those syst…
