The present research letter is dedicated to a detailed analysis of a double-gate tunnel field-effect transistor (DG-TFET). The DG-TFET provides improved on-current (ION) than a conventional TFET via bandto-band (B2B) tunneling. However, DG-TFET is disadvantageous for low-power applications because of increased off-current (IOFF) due to the large ambipolar current (Iamb). In this research work, a Si/GaAs/ GaAs heterostructure DG-TFET is considered as research base for investigation of device performance. The electrical parameters of the DG-TFET device have been improved in comparison to the homostructure. The transfer (I-V) characteristics, capacitance voltage (C-V) characteristic of homo structure Si/ Si/Si and hetero structure Si/GaAs/GaAs, DG-TFET both structures is analysed comparatively. The C-V characteristics of DG-TFET have obtained using operating frequency of 1 MHz. The ambipolar current Iamb is suppressed by 5 × 108 order of magnitude in proposed Si/GaAs/GaAs hetero DG-TFET as compared to Si/Si/Si homo DG-TFET up to the applied drain voltage very low equal to VDS = 0.5 V without affecting onstate performance. The simulation result shows a very good ION/IOFF ratio (10 13) and low subthreshold slope, SS (~36.52 mV/dec). The various electrical characteristics of homo and hetero DGTFET such as on-current (ION), off current (IOFF), time delay (ιd), transconductance (gm) , and power delay product (PDP) have been improve in Si/GaAs/GaAs heterostructure DG-TFET and compared with Si/Si/ Si homo DG-TFET. The advantageous results obtained for the proposed design show its usability in the field of digital and analog applications.

Oral dosage forms have many obvious advantages like simple, painless and self-administered. While the bioavailability of drugs are always low for they are unstable and usually degraded within gastrointestinal tract. Curcumin, a multifunction native compound, can be used in curing many diseases while the oral bioavailability is relatively low, limiting its clinical effectiveness. The aim of this study was to investigate the method of increasing the bioavailability by the addition of biotin, which was a kind of vitamin helping the liposomes to uptake by biotin receptors. In situ rat Single-Pass Intestinal Perfusion Model (SPIP) was applied to investigate the different content of biotin and caco-2 cells monolayer model was established to mimic the intestinal tract in drug transportation study. As the results shows that biotin decorated liposomes (biotin-PEG-DSPE-Lip) had a better cellular uptake and transportation rate compared to biotin undecorated ones (PEG-DSPE-Lip). It indicated that the bioavailability of curcumin had been increased.

The main objective of this work concerns the development of new eco-friendly composites based on biobased polymers for flame retardancy. Biobased cotton were employed as support for the fixation of biopolymers like chitosan (CT), titanium dioxide (TiO 2 ) as nanocharges, and polyvinylidene fluoride (PVDF) as binder. The resulting composites CO-TiO 2 -PVDF-CT were ther mally pressed to form compacted to ensure the surface compatibility. CO-TiO 2 -PVDF-CT were fully characterized by X-Ray diffractometer, scanning electron microscopy, optical microsco -py, contact angle, Fourier transform IR spectroscopy and differential scanning calorimetry. The thermal degradation, chemical coatings, surface modification properties were investigated. It was found that CO-TiO 2 -PVDF-CT composite are highly hydrophobic materials with good diffu sion resistance. PVDF and CT polymers induced an important role on the improvement of both flame retardancy and the thermal degradation. The degradation and elimination of FR from the composite product were studied. Finally, the toxicity of the prepared composite was performed to analyze the environmental impacts before and after the eco-path disposal treatment.

Shales make up about three fourths of drilled formation and over 90% of the wellbore instability problems that occur in shales. Even though shale stability has been studied for several decades, it still a serious problem in not only the petroleum industry but also in the mining and construction industries. Before any measures are taken to address this problem, it is crucial that potentially problematic formations and the mechanisms of wellbore instability be identified. Once the mechanisms are understood, well planning, drilling fluid design, and drilling operation strategies can be implemented to ensure wellbore stability. Due to the unique mechanical and physicochemical properties of shales, it is wellrecognized that wellbore instability in shales is a complicated problem. Shale cuttings consisting of different montmorillonite content were collected from four different wells in Sinai. They were evaluated using X-ray diffraction (XRD), X-ray fluorescence (XRF) and cation exchange capacity (CEC) using Methylene Blue (MB), hence classified into shale 1, 2 ,3 and 4. Swelling index of the shale measured using compressed disks of shale in contact with OCMA bentonite for 20 hrs using the Linear Swell Meter (LSM). Nanoparticles in terms of CuO, Graphene nanoplatelets and SiO2 used as an inhibitor of swelling of shale cuttings. The inhibitors are added to OCMA bentonite as well. Swelling of the shale directly related to montmorillonite content, more montmorillonite means more swelling in contact with OCMA bentonite. The inhibition of swelling of these shale cuttings using KCl achieved a decrease in swelling that ranged from 15% at 7% (shale 1), 14% at 6% (shale 2), 14% at 4% (shale 3) and 17% at 9% (shale 4). with estimates over $1 billion in annual cost to the industry. Preventing shale instability is a high priority to every phase of the drilling fluids industry, from research and development efforts to field implementation by the mud engineers.

This paper shows the synthesis of copper sulfide (CuS) nanoparticle by co-perception method at low temperature and the synthesis of copper sulfide/graphene sheets (CuS/Gs) nanocomposite by hydrothermal method at 120 °C. The structure, surface morphology and size of nanoparticles (NPs) are discussed and analyzed by X-ray diffraction analysis (XRD), energy dispersive X-ray analysis (EDX) and transmission electron microscopy (TEM). The obtained nanoparticles have sizes between (4-10 nm). We are studied the effect of graphene-based nanoparticles nanocomposite on the thermal properties by thermogravimetric analysis (TGA). The photocatalysis properties are investigated at different conditions. The result shows that the graphene sheet (Gs) nanocomposite effect the composition and the thermal properties of nanoparticles.

Fe doped ZnO solid solution and its semiconductor thin films were prepared by sol-gel method. After aging and quenching, the films were characterized by X-ray diffraction (XRD) and atomic force microscopy (AFM). The elemental proportion was obtained by energy dispersive spectrometer (EDS) and the magnetic properties were measured by magnetic force microscope (MFM). The results show that iron doping can inhibit the growth of zinc oxide particles, and then increase the roughness of thin films. The results of MFM show that Fe doping can make non-magnetic ZnO semiconductors become dilute magnetic semiconductors. With the increasing amount of Fe doping, the distribution of magnetic domains and magnetic moments becomes more obvious.

The crystalline silicon quantum dots (Si QDs) depending on growth temperature were investigated using plasma enhanced chemical vapor deposition. The size of Si QDs was increased with increasing growth temperature and the ratio between silicon-related gas flow and nitrogen-related gas flow. This is because the growth rate of Si QDs decreases due to surface sites blocking by hydrogen. Hydrogen atoms dissociated from N-H and Si-H could promote the growth of crystalline phase silicon QDs.
