Abstract:

The aim of the study was to investigate the suitability of a convection oven to induce in situ amorphization. The study was conducted using microwave radiation-induced in situ amorphization as reference, as it has recently been shown to enable the preparation of a fully (100%) amorphous solid dispersion of celecoxib (CCX) in polyvinylpyrrolidone (PVP) after 10 min of continuous microwaving. For comparison, the experimental setup of the microwave-induced method was mimicked for the convection-induced method. Compacts containing crystalline CCX and PVP were prepared and either pre-conditioned at 75% relative humidity or kept dry to investigate the effect of sorbed water on the amorphization kinetics. Subsequently, the compacts were heated for 5, 10, 15, 20, or 30 min in the convection oven at 100 °C. The degree of amorphization of CCX in the compacts was subsequently quantified using transmission Raman spectroscopy. Using the convection oven, the maximum degree of amorphization achieved was 96.1% ± 2.1% (n = 3) for the conditioned compacts after 30 min of heating and 14.3% ± 1.4% (n = 3) for the dry compacts after 20 min of heating, respectively. Based on the results from the convection and the microwave oven, it was found that the sorbed water acts as a plasticizer in the conditioned compacts (i.e., increasing molecular mobility), which is advantageous for in situ amorphization in both methods. Since the underlying mechanism of heating between the convection oven and microwave oven differs, it was found that convection-induced in situ amorphization is inferior to microwave radiation-induced in situ amorphization in terms of amorphization kinetics with the present experimental setup.

Abstract:

Two kinds of radiation-induced structural changes were observed in U-Mo/Al dispersion fuel: radiation-induced recrystallization of U-Mo fuel particles and radiation-induced amorphization of interaction products. During irradiation, U-Mo fuel showed refined microstructures of submicron-size grains due to dynamic recrystallization, occurring initially from pre-existing grain boundaries. The interaction products formed by interdiffusion between the U-Mo particles and Al matrix in U-Mo/Al dispersion fuel transformed from crystalline to amorphous during irradiation. In this paper we deal with both of the phenomena simultaneously.

Abstract:

Electron irradiation-induced amorphization of CuTi was studied by high resolution electron microscopy (HREM). Special attention was directed to correlate the spacial distribution of structural change from the perfect crystalline state to the complete amorphous state with the electron density distribution of the focussed beam which was used to amorphize the specimens.An alloy button of Cu-54 at % Ti was prepared by arc-melting and subsequently annealed at 1173K for three days. HREM samples were spark-cut and thinned by jet polishing. The samples were first examined in a Hitachi H 9000 HREM and selected for irradiation at 10K in a 1.2 MeV Kratos-AEl EM 7 high voltage electron microscope. The irradiation was carried out by a fully focused beam for which the electron density distribution was pre-determined. Finally, the irradiated samples were reexamined across the crystal/amorphous (C/A) boundary in the H 9000. The electron dose at the point of examination was estimated by carefully comparing the positions in HREM images with the interrupted position of bend contour in low magnification and utilizing the electron density distribution.

Abstract:

This work presents a summary on the use of rapid thermal processing for implant annealing. It gives a short historical overview of rapid thermal processing systems and the first implant anneal processes on these newly developed tools. We then looked in detail on the soak anneal and spike anneal processes and the influence of certain process parameters. For the soak anneal influences of the ambient, either oxidizing or nitriding, were evaluated. The results of spike anneal processes are influenced by the pre-stabilization temperature, ramp-up and ramp-down rate, peak temperature, and gaseous ambient. The need for shallow, abrupt and highly activated junctions leads to co-implantation of species like fluorine or carbon in conjunction with pre-amorphization. Nowadays, combinations of spike and millisecond annealing as well as millisecond annealing alone are in the focus.

Abstract:

Abstract Realization of radiation-hard electronic devices that are able to work in harsh environments requires deep understanding of the processes of defect formation/evolution occurring in semiconductors bombarded by energetic particles. In the present work we address such intriguing radiation phenomenon as high radiation tolerance of GaN and analyze structural disorder, employing advanced co-irradiation schemes where low and high energy implants with different ions have been used. Channeling analysis revealed that the interplay between radiation-stimulated defect annealing and defect stabilization by implanted atoms dominates defect formation in the crystal bulk. Furthermore, the balance between these two processes depends on implanted species. In particular, strong damage enhancement leading to the complete GaN bulk amorphization was observed for the samples pre-implanted with fluorine ions, whereas the co-irradiation of the samples pre-implanted with such elements as neon, phosphorus and argon leads to a decrease of the bulk damage.

Full text

Abstract:

This study reports for the first time the transformation of the pre-made FAU type of zeolite to the EDI type of zeolite. The concentration of the KOH solution controls this interzeolite transformation, which unusually occurs at both room temperature and under hydrothermal conditions. The transformation involves the amorphization and partial dissolution of the parent FAU phase, followed by the crystallization of EDI zeolite. At room temperature, the transformation (11–35 days) provides access to well-shaped nano-sized crystals and hollow hierarchical particles while the hydrothermal synthesis results in faster crystallization (6–27 h). These findings reveal an example of an interzeolite transformation to a potassium zeolite that lacks common composite building units with the parent zeolite phase. Finally, this work also demonstrates the first room-temperature synthesis of EDI zeolite from a gel precursor.

Abstract:

Solid dispersions (SDs) of simvastatin with mannitol, Ineutic®, Pluronic® F-68, PEG 4000 and PVP K-30 were prepared and evaluated to deliver simvastatin to the colon in a pre-solubilized form. The formula of choice was compressed into fast disintegrating tablets using drug compatible excipients and was coated with Eudragit® S100 as a pH-responsive polymer. We investigated the effects of several variables related to both SD preparation (carrier type, combined carriers and drug to carrier ratio) and tablet coating (coat level and type of plasticizer) on drug dissolution. Differential scanning caloremitry (DSC) and scanning electron microscopy (SEM) proved drug amorphization in SDs. The 1:5 simvastatin/ Pluronic® SDs showed the greatest improvement in dissolution efficiency (12.2-fold) at the lowest carrier ratio. The coating level was critical for determining the duration of the lagphase. Best results were given by the 10% coat (20:2:1 w/w Eudragit S100/ triethylcitrate/ talc). This formula resisted pre-colonic pH values and showed an adequate lag time for the intended colonic targeting (4 h), followed by an immediate release phase (t50%=249 min) in pH 7.4. The proposed coated tablets may provide a colonic delivery system for simvastatin with improved bioavailability.

Abstract:

Purpose This work aims to analyze the effect of mechanical activation on structural disordering (amorphization) in an alumina-silica ceramics system and formation of mullite most notably at a lower temperature using X-ray diffraction (XRD). Also, an objective of this work is to focus on a low-temperature fabrication route for the production of mullite powders. Design/methodology/approach A batch composition of kaolin, alumina and silica was manually pre-milled and then mechanically activated in a ball mill for 30 and 60 min. The activated samples were sintered at 1,150°C for a soaking period of 2 h. Mullite formation was characterized by XRD and scanning electron microscopy (SEM). Findings It was determined that the mechanical activation increased the quantity of the mullite phase. SEM results revealed that short milling times only helped in mixing of the precursor powders and caused partial agglomeration, while longer milling times, however, resulted in greater agglomeration. Originality/value It is noted that, a manual pre-milling of approximately 20 min and a ball milling approach of 60 min milling time can be suggested as the optimum milling time for the temperature decrease succeeded for the production of mullite from the specific stoichiometric batch formed.
