This work revisits the classical subject of recrystallization of cold-rolled copper. Two characterization techniques are combined: three-dimensional X-ray diffraction using synchrotron X-rays, which is used to measure the growth kinetics of individual grains in situ, and electron backscatter diffraction, which is used…
Caustic magnesia (CM) and magnesia sinter (MS or hard-burnt magnesia) are the main sources of MgO employed in industry. Both are obtained from the calcination of Mg(OH)2 or MgCO3, however, due to differences in their manufacture, they display significant distinct physical–chemical properties. MS is produced at tempera…
In this study, the effect of ion type and concentration on the heteroaggregation and release of multiwalled carbon nanotubes (MWCNTs) and hydroxylated MWCNTs (OH-MWCNTs) with sediments is reported. Means of the first-order heteroaggregation rate constant (khet) for MWCNTs and OH-MWCNTs and a freshwater sediment in 0.4…
Three new dimethyl aluminium complexes 1 – 3 containing aminophenol ligands ( LAlMe 2 , where L1 = diethylaminophenoxide, L2 = diisopropylaminophenoxide and L3 = piperidinophenoxide) were synthesized and characterized by different spectroscopic techniques and elemental analysis. The solid state structure of 1 was dete…
The first principle modelling and experimental approach were used to investigate the role of oxide on ferrite formation. Ti2O3 was found to be effective in inducing ferrite formation owing to its lower cation vacancy energy. Al2O3 was inert in promoting the formation of ferrite because it has high cation and anion vac…
Denim Jeans finishing is an important operation for value addition of the final products in the apparel business. There are numerous operations exist for fulfilling of this treatment. This paper deals with the recent developments of the sustainable, environment friendly and emerging industrial approaches (Laser, Ozone…
Interaction between the complement system and carbon nanotubes (CNTs) can modify their intended biomedical applications. Pristine and derivatised CNTs can activate complement primarily via the classical pathway which enhances uptake of CNTs and suppresses pro-inflammatory response by immune cells. Here, we report that…
A new approach to calculate the effective Ln–Ln energy transfer rates in a doped crystal matrices was proposed and successfully applied to the YVO4:Yb3+,Er3+ upconversion system. This approach is based on the known set of Ln–Ln distances obtained from the crystal structure of the matrix and the probabilities of their…
Biocomposites reinforced by natural plant fibers tend to be brittle, moisture sensitive and have limited strength. Wood cellulose nanofibers (CNF) were therefore used to reinforce an unsaturated polyester matrix (UP) without the need of coupling agents or CNF surface modification. The nanostructured CNF network reinfo…
We investigated the individual properties of various polyion-coated bubbles with a mean diameter ranging from 300 to 500 nm. Dark field microscopy allows one to track the individual particles of the submicron bubbles (SBs) encapsulated by the layer-by-layer (LbL) deposition of cationic and anionic polyelectrolytes (PE…
Among a variety of solution-based approaches to fabricate anisotropic films of aligned carbon nanotubes (CNTs), we focus on the dielectrophoretic assembly method using AC electric fields in DNA-stabilized CNT suspensions. We demonstrate that a one-stop manufacturing system using electrode needles can draw anisotropic…
We investigated the fundamental electrical properties of microbubbles (MBs) that are directly encapsulated by the addition of oppositely charged polyelectrolytes (PEs). Charge-reversal of the MB-PE complex particles has been observed by the microscopic electrophoresis method, revealing unusual overcharging behaviors i…
Process zone at the tip of a propagating crack engendered by the stress-induced local phase transition of the second order is studied theoretically. We show that the zone can only exist within a certain domain of the phase diagram at one side of the phase transition line depending upon the sign of the striction consta…
Nanotechnology has the potential to innovate the agricultural, feed and food sectors (hereinafter referred to as agri/feed/food). Applications that are marketed already include nano-encapsulated agrochemicals or nutrients, antimicrobial nanoparticles and active and intelligent food packaging. Many nano-enabled product…
Bu çalışmada, yeni bir N-sübstitüe metakrilamit monomeri sentezlenerek bu monomerin homopolimerizasyonu ve metil metakrilat (MMA) ile kopolimerizasyonu çalışıldı. N-(2-asetilbenzofuran-3-il)metakrilamit (NABM) olarak adlandırılan monomer, 1-(3-amino-1-benzofuran-2-il)etanon (bu bileşik 1-kloraseton ile 2-hidroksi benz…
The structure properties of random mask of antireflective structure prepared by the thermal dewetting process are investigated. As a low-cost and large-scale technique, the mask obtained in our work has a great prospect in the field of solar cell and high power laser system. Ultrathin films of amorphous Ag are deposit…
One of the major restrictions that hinder the versatility of electrical machines in any sector is their thermal limitations. This thesis deals with the study of the heat transfer occurring in an outer rotor permanent magnet synchronous machine used in the electric vehicle industry with the aim of exploring possibiliti…
LATAR BELAKANG : Pembedaan secara histologik antara adenokarsinoma yang berasal dari endometrium dengan yang berasal dari serviks mungkin sulit, terutama pada biopsi kecil atau spesimen kuretase. Darimana pertumbuhan tumor berasal, apakah dari endometrium atau endoserviks, sering menjadi permasalahan, sementara dalam…
With the development of holography technique and nano-superfinishing technique, holography grating has being used into the spectrometer. To overcome some drawbacks of optical system for traditional plane and concave grating typed spectrometer, a splitting-light optical system for spectrometer based on volume phase hol…
Le transport thermique dû à des excitations magnétiques dans les composés 1D contenant des chaines et échelles de spins fait actuellement l’objet d’une collaboration fructueuse entre chimistes et physiciens du solide. Le composé à chaines de spins Sr₂CuO₃, qui est un excellent exemple de chaine de type Heisenberg anti…
