The electrode material with nanostructured features is a key point in electrochemical application to enhance the electrochemical activities. Nowadays, more researchers are concentrated on the synthesis of hierarchical nanostructured architecture with smaller particle size employing different synthesis tools. Without the use of an additive binder hydrothermal route was employed for the synthesis of self-assemble nanostructures of single (Ni3S2) and binary metal sulphides (NiCo2S4) with particle size near about 10 nm for assymmetric supercapacitor application. The prepared samples were used for structural and surface morphological studies using different characterization techniques and then electrochemical measurements were performed. Through the electrochemical measurements, a significant difference in the performances of both electrode materials was observed. Achieving the better electrochemical activities for CoNi2S4-µflower with 2098.95 F g-1 specific capacitance, the asymmetric supercapacitor designed with Ni3S2-nanorod is one of the electrode. The designed hybrid asymmetric supercapacitor, based on Ni3S2-nanorod//CoNi2S4-µflower electrodes, exhibits a specific capacitance of 54.92 F g-1 at a scan rate of 5 mV s-1. The assembled asymmetric supercapacitor has an energy density of 6.6 Wh kg-1 while delivering a power density of 820 W kg-1. The capacitive retention of the initial capacitance remains desirable at 89.13 % after 5000 CV cycles at a scan rate of 100 mV s-1. The present work manifests a vision for the fabrication of self-assembled, binder-free electrodes for high-performance hybrid supercapacitor application.

‘History is teacher of life’ as Romans expressed. It is a very significant matter of fact which contains the past, the present and the future of the societies, also has a very important place in improving the social consciousness. One of the most important duty of the mankind is to protect such a worthy history heritage. Archives that made by paper are one of the main parts of our past.
Paper can be deteriorated due to physical, chemical and biological based factors such as acidity, metal ions, lightning, heat, humidity, UV light, pollutants or biodeteriogens. Among these factors, for one, microorganisms can damage on papers irrevocably via releasing some reactive groups.
In this study focused on conservation of historical paper samples by using silver-chitosan Nano composite coating to gain antibacterial and antifungal feature. It is well known that Ag nanoparticles possess antibacterial properties. Chitosan, a polysaccharide biopolymer derived from naturally occurring chitin, displays unique polycationic, chelating and film forming properties due to the presence of active amine and hydroxyl functional groups, is a natural polymer that is both non-toxic and biodegradable. Silver-chitosan Nano composite produced at specific temperature via solvothermal method. Then produced samples are characterized via Scanning Electron Microscopy (SEM). Coating of sample papers are carried out by using three different methods that called dipping, spraying and electrospinning. Afterwards micro-organism growth tested in Süleymaniye Manuscript Library.

Magnetic NanoRods (NR) have been used inside cells to deform cytoplasm and cellular membrane, and to generate cell death. Cell death has been studied as selective therapy against malign cells. However, the mechanism of action that leads to this kind of death remains unknown. To describe this mechanism, we analyzed cell membrane integrity after been treated with magnetic NRs that rotate at low frequency and NRs effect on cell proliferation rate. To do this, we fabricated Ni-Pt NRs by electrodeposition into porous alumina templates, being one of the first studies that analyze Pt particles of this size inside any kind of cells. We designed a low frequency Magnetic Field (MF) generation system with temperature control to allow NRs to rotate inside cells avoiding thermal stress. We incorporate NRs to fibroblast NIH/3T3 cell culture and after one day MF was applied. Membrane integrity was identified by specific dye 20 minutes after treatment. We confirmed NR incorporation by a microscopy video of a single NR rotating inside a single cell and bouncing against its membrane. Membrane integrity damage was only found in cells treated simultaneously with NRs and MF, thus cell death mechanism is necrotic-like since apoptosis needs more time to occur. Proliferation inhibition was observed on cultures with NRs, indicating that particles alter cell cycle and needs to be functionalized to be biocompatible. This will allow us to understand the effect of NRs on cell death.

The extreme light confinement provided by sub-wavelength metal-dielectric structures
pushes towards revisiting the design rules of the photo-detectors. Furthermore,
introducing absorbing layers in optical nano-resonators demands a dedicated
electromagnetic design. Developing together semiconducting heterostructures and
optical nano-antennas opens the way for performance improvements and new
functionalities, introducing very promising features such as ultra-thin absorbing layers
and device area much smaller than its optical cross-section. High responsivity, highspeed
behavior, and carved optical response are among the expected properties of this
new generation of photo-detectors.
In this talk, I present a GMR InGaAs photo-detector dedicated for FPA applications as an
illustration of this global design. I discuss the cross-linked properties of the optical and
semiconductor structures. Experimental results show at λ = 1.55 μm an EQE of 75% and
a specific detectivity of 1013 cm.√Hz.W-1.

α-Synuclein (α-Syn) is a protein presence in the brains of a range of neurodegenerative disorders’ patients as plaque-like compact structures in the form of amyloid fibrils. There is a strong relationship between α-Syn amyloid fibrillation and the pathology of the neurodegenerative disorders such as Parkinson’s disease. There is a serious effort to apply the compounds, known as small molecules, with inhibitory effects on the different steps of α-SN fibrillation and also its related neurotoxicity. However, the small molecules can possess some problems like high hydrophobicity/ low solubility in physiological fluids, instability, and difficulty in passing across blood brain barrier (BBB). In this respect, employing of nanocarriers has been pointed because of a lot of advantages i.e. biocompatibility, easy surface modification, low immunogenicity, protecting cargo against enzymatic degradation. In this regard we used three different nanocarriers including serum albumin nanoparticles (SA- NPs)(, mesoporous silica nanoparticles (MS-NPs)  and neutral charged nanoliposomes(NC-NLPs). We found that each kind of nanocarrier possess specific characters when applying for loading drugs or treating α-Syn or neuronal cells. SA- NPs with a moderate drug loading efficiency (DLE) for polyphenols, showed some inducing effect on α-Syn fibrillation when treating with bare SA- NPs. Although MS-NPs with similar DLE did not show inducing effect on α-Syn fibrillation, they had a small neurotoxicity effect. On the other hand, NC-NLPs had high DLE for polyphenols and also they did not indicate any considerable induction on the α-Syn fibrillation or any neurotoxicity effects. It seems that NC-NLPs have more potential for using regarding synucleinopathies treating than the two other NPs.

Influence of neutron irradiation on reactor pressure vessel (RPV) steel degradation are examined with reference to the possible reasons of the substantial experimental data scatter and furthermore – nonstandard (non-monotonic) and oscillatory embrittlement behavior. In our glance this phenomenon may be explained by nanostructure evolution of steel during irradiation that result in self-organization appearance and presence of the wavelike recovering component in the embrittlement kinetics. We suppose that the main factor affecting steel anomalous embrittlement is fast neutron intensity (dose rate or flux), flux effect manifestation depends on state-of-the-art fluence level. At low fluencies radiation degradation has to exceed normative value, then approaches to normative meaning and finally became sub normative.
In our opinion controversy in the estimation on neutron flux on radiation degradation impact may be explained by presence of the wavelike component in the embrittlement kinetics. Therefore flux effect manifestation depends on fluence level. Owing to nanostructere evolution at low fluencies radiation degradation has to exceed normative value, then approaches to normative meaning and finally became sub normative. Paradoxically as a result of dose rate effect manifestation peripheral RPV’s zones in some range of fluencies have to be damaged to a large extent than situated closely to core.
We suppose that at some stages of irradiation damaged metal have to be partially restored by irradiation i.e. neutron bombardment. Nascent during irradiation nanostructure undergo occurring once or periodically evolution in a direction both degradation and recovery of the initial properties. According to our hypothesis at some stage(s) of metal nanostructure degradation neutron bombardment became recovering factor.

Hybrid nanomaterial (powdered fungi and ZnFe2O4) was developed and studied for gas sensing application, specifically for NO2 gas detection. In this study, powdered Rhizopus species W3 and ZnFe2O4 nano-powder were mixed at equal proportion to carryout sensing experiments. The conjugated material film was coated on the interdigitated electrodes (IDEs) by drop drying method, to determine the NO2 gas sensing characteristics. It was found that the response of these hybrid material decrease resistance, thereby resembling to p-type semiconductor. The fungi W3- ZnFe2O4 hybrid composite sensor showed better response, sensitivity, selectivity, stability and reproducibility at room temperature towards 30 ppm of NO2. N. Miura et al reported in 2002 ZnFe2O4 shown good sensitivity for NO2 (436 ppm) at 700 ̊C operating temperature . Therefore, In the present work effort was made to prepare novel hybrid material that is feasible, eco-friendly, flexible, cost-effective, low maintenance and light weight new device.
