Polymeric micelles are known for their prominent ability to favourably accumulate at solid tumours by the enhanced permeability and retention (EPR) effect, enabling a targeted drug delivery. In this work, PEGylated phospholipid and basic polymeric micelles (15 to 22 nm) were chosen as lipid-based carriers for poorly s…

By using the tight-binding energy band theory, we study the band structures of BC3 nanotubes under stretching and compressing deformations, the conductivity band turns more and more close to the valence band of the BC3 nanotubes and eventually they overlap each other with the increase of tension. Furthermore, the resu…
There are many different shielding technologies available for electromagnetic interference (EMI) shielding in radio frequency (RF) applications. We will investigate various EMI shielding technologies, one of which is RFMD's MicroShield™ Integrated RF Shielding technology's conformal plating process that encapsulates t…
Polycrystalline zinc oxide thin-film transistors have been built using a simple process technology that combines in one step the etching of the gatestack and the doping of the source/drain regions. The resulting transistors exhibit an effective mobility of ∼173 cm2/Vs, a linearly extrapolated threshold voltage of ∼1V,…
The decomposition of solids in reactive gas atmospheres has been the subject of numerous studies over a wide range of chemical systems. Whilst significant advances have been made in understanding and describing the influence of gas phase mass transfer on these processes, the key process phenomena and physico-chemical…
As diatomáceas bênticas formam biofilmes à superfície dos sedimentos intertidais estuarinos e constituem um dos grupos de produtores primários mais importantes. Estas microalgas têm a capacidade de se deslocar activamente por entre as partículas do sedimento, processo associado à libertação de substâncias extracelular…
Photochromic textiles from hybrid silica coatings: improvement of photostability
This paper considers the effects of CO2 emission trading system on the substitution between coal and energy wood in the large scale heat and power production in Europe. We use a technology-based approach where the substitution between coal and wood takes place through switch from one technology to another over time. T…
Inclined Al2O3 column array was fabricated by using hollow nanosphere template. Birefringence and photonic crystals behavior can be observed in the orderly inclined column array. Compared to substrate without patterns, photonic crystals property was enhanced.
The formation of anodic aluminium oxide (AAO) film in anodising process has been studied. The anodising process was done in a mixture of phosphoric acid and acetic acid. The purpose of mixed acid solution as electrolyte is to increase the efficiency of AAO film formation. This study was performed to determine optimum…

Plants of the family Guttiferae produce polycyclic polyprenylated acylphloroglucinols (PPAPs), which have interesting biological activities including anticancer and antibacterial properties. The main structural features of PPAPs comprise of bicyclo[3.3.1]nonane-2,4,9-triketone with one acyl group together with prenyl,…
In this work, PMMA/LDHs nanocomposites were prepared by modifying MgAl、LiAl layered double hydroxides before in-situ polymerization of PMMA. PMMA/LDHs nanocomposites show the enhanced physical, mechanical and chemical properties when compared to pure PMMA. Two types of LDHs with different anionic exchange capacity (AE…
The hydrophilicity of nanofibrous structures is a key characteristic for many applications. However due to the high porosity of the structures, it is difficult to measure this property with contact angle measurements. Therefore a characterisation through wicking behaviour is more appropriate. The ISO-norm on wicking b…
research of distribution of residual stresses is conducted in pipes of various factories of manufacturers. Modes of processing of pipes for reception of considerable compressing stresses on both surfaces are defined. Dependences of corrosion and mechanical properties on a tension are investigated. The design procedure…
In this thesis, constrained 7/8 helix has been developed to enhance the stability of 7/8 helical structure in polar and aqueous solvents for biological application. \n \nThe synthesis of constrained 7/8 helical peptides has been achieved in two steps. In the first step, a 7/8 helical peptide chain comprising alternat…
Attractive particle interactions which lead to enhanced rheology of concentrated mineral dispersions are encountered in a number of hydrometallurgical mineral processing operations. The presence of reactive clay minerals (e.g., muscovite and chlorite) plays a pivotal role in defining the pulp chemistry and concomitant…
