“…If electron and hole motions are confined in threedimensional spaces, this phenomenon leads to quantum confinement effect. This effect is observable if the particle size of the nanostructured thin films is comparable or smaller than its Bohr exciton diameter which acts as a natural length scale of the electronhole pair [2,12]. It was observed from Figure 6 that the optical film transparency increased with increasing saccharin addition in the growth baths.…”

“…It is known that saccharin which so-called as benzoic sulfimide is an artificial sweetener. Saccharin has been used as an additive agent in the reaction medium in order to improve the characteristics of nanoparticles [10][11][12]. We aimed in this submission to show the influence of saccharin level on the crystal structure, particle size, optical properties and surface roughness of the PbS thin films.…”

Saccharin which so-called as benzoic sulfimide is an artificial sweetener. In this paper, nanostructured lead sulfide (PbS) thin films were produced in the presence of additive known as saccharin via chemical bath deposition (CBD). Effect of the saccharin content on the morphological, optical and structural properties of the films has been investigated. Lead sulfide (PbS) films that included additive were prepared at five different concentrations of saccharin (from 0 to 5%). The fabricated samples were characterized by surface roughness, scanning electron microscopy (SEM), X-Ray diffraction and UV-vis spectroscopy. It was found that the presence of saccharin highly affected the optical and structural properties of PbS thin films. According to the X-Ray diffraction results, crystallite size values of the films decreased from 12.88 to 5.25 nm with increasing of saccharin content. UV-vis measurements showed that both the band gap and transmission properties of the films increased as a result of increasing saccharin concentration. Further, Surface roughness measurements exhibited that average surface roughness was diminished with increasing saccharin content. As a result, it has been found that the presence of saccharin in growth solution played a significant mission in adjusting the main physical properties of the samples. Sakarin İlavesiyle Cam Altlıklar Üzerine CBD ile Büyütülen PbS Filmlerin Morfolojik, Yapısal ve Optik Özelliklerinin Modifikasyonu Anahtar KelimelerYüzey pürüzlülüğü, Kurşun sülfür, Sakarin, Kimyasal banyo depolama Özet: Benzoik sülfimid olarak da bilinen sakarin yapay bir tatlandırıcıdır. Bu makalede, nanoboyutlu kurşun sülfür (PbS) ince filmler sakarin olarak bilinen katkı maddesi varlığında kimyasal banyo depolama (CBD) ile üretilmiştir. Sakkarin miktarının filmlerin morfolojik, optik ve yapısal özelliklerine etkisi araştırılmıştır. Katkı maddesi içeren kurşun sülfür (PbS) filmler sakarinin beş farklı konsantrasyonunda (%0 dan %5'e) hazırlanmıştır. Üretilen numuneler yüzey pürüzlülüğü metodu, taramalı elektron mikroskopisi (SEM), X-Işını kırınımı ve UVvis spektroskopisi ile karakterize edilmiştir. Sakarin varlığının PbS ince filmlerin optik ve yapısal özelliklerini oldukça etkilediği bulunmuştur. X-Işını kırınımı sonuçlarına göre, filmlerin kristal boyutu değerleri sakarin içeriğinin artmasıyla 12.88 nm'den 5.25 nm'ye düşmüştür. UV-vis ölçümleri artan sakarin konsantrasyonunun bir sonucu olarak hem filmlerin bant aralığının hem de geçirgenlik özelliklerinin arttığını göstermiştir. Ayrıca, yüzey pürüzlülüğü ölçümleri sakarin miktarının artmasıyla ortalama yüzey pürüzlülüğünün azaldığını göstermiştir. Sonuç olarak, büyütme çözeltisinde sakarin varlığının numunelerin temel fiziksel özelliklerini ayarlamada önemli bir görev üstlendiği tespit edilmiştir.

This piece of work is focused on the evaluation of an alternate route to recover nickel from NiMH residual batteries beginning from the mechanical stage of disassembly, fragmentation and conditioning of powders by means of the process of mechanofusion and the stage of extraction of nickel from acidic electro deposition. By means of the process of mechanofusion, the properties of the particles are modified with a view to increasing the efficiency of the electrolytic treatment via the size control, particle form and the dispersion of species on a particle bed. The obtaining of metallic nickel was made at 50 mA/ m 2 at a temperature of 21°C via electrolysis with a constant potential producing a deposit of 295 ppm Ni. Keywords: NiMH, Nickel, mechanofusion. ResumenEste trabajo se orienta a la evaluación de una ruta alternativa para recuperar Ni a partir de baterías de NiMH de desecho partiendo de la etapa mecánica del desensamble, la fragmentación, acondicionamiento de polvos por el proceso de mecanofusión y la etapa de extracción de níquel por electrodeposición ácida. A través del proceso de mecanofusión, las propiedades de las partículas son modificadas con vista a aumentar la eficiencia del tratamiento electrolítico, vía el control del tamaño, forma de las partículas y la dispersión de especies en un lecho de partículas. Los polvos obtenidos pueden entonces ser utilizados en disoluciones acuosas, a presión ambiente y temperaturas por debajo de 50°C para formar depósitos por la reducción de los iones de Ni presentes en la solución electrolítica. La obtención de Ni metálico se realizó a 50 mA/ m 2 a 21°C, por electrólisis a un potencial constante produciendo un depósito de 295 ppm de Ni.

Two Molar ratios 1 : 1 and 1 : 2 of AR grade nickel oxide and iron oxide powder was mixed and compacted. The fired compacts were isothermally reduced in pure hydrogen at 500, 550, 600 and 650 C. Based on thermogravimetric analysis, the reduction behavior and kinetics reaction mechanism were studied comparatively for the different mixed oxides ratios. The initial fired powder and the various reduction products were characterized by XRD, SEM, TEM and reflected light microscope to reveal the effect of hydrogen reduction on composition and microstructure of produced Ferronickel alloy. Synthesis of nanocrystalline Fe 1Àx Ni x alloy with 33 and 20 at% Ni for reduction of 1 : 1 and 1 : 2 NiO/Fe 2 O 3 ratios was detected respectively. The activation energy values were calculated from Arrhenius equation and the approved mathematical formulations for the gas solid reaction were applied. It was found that for NiO/Fe 2 O 3 of both 1 : 1 and 1 : 2 ratios, the initial reduction stages is controlled by the combined gaseous diffusion and interfacial chemical reaction mechanisms while at the final reduction stages the reaction is controlled by the interfacial chemical reaction mechanism.
