Nickel nanoparticles were electrochemically deposited on indium-tin oxide (ITO) coated glass plate in a modified Watt’s electrolyte. The surface-enhanced infrared absorption (SEIRA) effect of the nanoparticles was evaluated by attenuated total reflection spectroscopy (ATR-FTIR) using o-nitroaniline as a probe molecule. Electrodeposition parameters such as deposition time, pH value, and the type of surfactants were investigated. The morphology and the microstructure of the deposits were characterized by the field emission scanning electron microscope (FESEM) and the atomic force microscope (AFM), respectively. The results indicate that the optimum parameters were potential of 1.3 V, time of 30 s, and pH of 8.92 in the solution of 0.3756 mol/L diethanolamine, 0.1 mol/L nickel sulfate, 0.01 mol/L nickel chloride, and 0.05 mol/L boric acid. The FESEM observation shows that the morphology of nickel nanoparticles with best enhancement effect is spherical and narrowly distributed particles with the average size of 50 nm. SEIRA enhancement factor is about 68.

Cost Effective Technique

Electrodeposition is considered an easy and cost effective technique for the manufacture of alloy layers. Various properties for coatings can be achieved by selecting various electrodeposition parameters. These materials have the advantage of corrosion resistance but relatively expensive. They will need alternative materials that can easily obtained and replace these materials. This paper discusses the process of coating stainless steel AISI 304 and copper with Ni. Electric current and coating time is used in the electroplating coating process of Ni to Ni thickness supported by ultrasonic batch. AISI 304 stainless steel and copper coated using nickel (Ni) with variable time and fixed electric current parameters. The electric current used 1.5 ampere, the time of plating process of 60 seconds, 120 seconds, and 180 seconds. The composition of nickel electrolyte solutions using nickel sulfate 300 gr/L, nickel chloride 30 gr/L, and sour borax 30 gr/L with brighteners added one (I) 15 mL and brighteners two (II) 1 mL. Measurement of thickness is done by using optical microscope assisted by imageraster software. The best process used 1.5 amperes of electric current and time of 180 seconds. The value of copper thickness is 26.50 (μm) using ultrasonic batch.

Introduction: Patch testing is a diagnostic tool used in investigation to identify specific allergens in allergic contact dermatitis (ACD). It helps find the prevalence and the trends of contact sensitization in the community. Objective: To report the two year patch test results from a central hospital in Kathmandu. Materials and Methods: Consecutive consenting patients of suspected ACD were patch tested with an Indian standard Series (Systopic) from June 2014 to August 2016. Results: Out of 141 patients tested, 89 were female (63.12%) and 52 were male (36.88%). Hand eczema was the commonest pattern (53 patients) followed by persistent and recurrent eczema (44 patients) and face eczema (25 patients). Fifty- five patients (39%) had at least 1 positive allergic reaction. Among these, 16.31% were male and 22.70% were female. The most common allergen was nickel sulfate (19.9%) followed by fragrance mix (7.8%) and paraphenyldiamine (PPD) (6.4%). Out of total positive cases 27 (21 females and 6 males) had shown strong positive reactions (++). The Nickel Sulfate was responsible in majority of cases (18/27 cases). Farmers had the highest (57.14%) rate of positive allergic reactions followed by housewives (39.62%). According to the regional eczema, patients with persistent and recurrent eczema of different parts of body had the highest rate of positive allergic reactions (47.72%). Almost half of patient with facial eczema (40%) had positive patch test. Conclusion: Larger studies are required in the different parts of the country to find a more accurate data regarding the sensitization pattern in Nepalese population.

AbstractElectrodeposition of nickel from slightly acidic gluconate solutions containing chloride or/and sulfate ions was investigated. Electrochemical measurements correlated with bath speciations showed nickel chloride complex and nickel sulfate complexes as crucial species affecting cathodic reactions in a potential range up to −1.3V. At more negative potentials, nickel deposition was governed by a release of nickel cation from nickel-gluconate complex. This was further evidenced by differences in nucleation modes, morphology, and structure of the deposits. Wettability of as-plated and chemically modified nickel layers were determined and correlated with their morphology and corrosion resistance.

Background: Patch testing is routinely used in contact dermatitis clinics because it is the gold standard for the evaluation of potential allergic contact dermatitis. Objective: The study was undertaken to evaluate possible differences in reactivity between the Finn Chamber and IQ-Ultra patch-testing methodologies. Methods: Patients were patch-tested simultaneously with the Finn Chamber and IQ-Ultra patch tests. Ten standard allergens set by the North American Contact Dermatitis Group were used for both techniques. Results: Both patch tests had a significant agreement in detecting all of the allergens. An “almost perfect agreement” was noted for ethylenediamine dihydrochloride, quaternium-15, mercapto mix, black rubber mix, balsam of Peru, and nickel sulfate; “substantial agreement” for formaldehyde, bisphenol A epoxy resin, and 4-tert-butylphenol formaldehyde resin; and “moderate agreement” for potassium dichromate. Conclusion: The Finn Chamber and IQ-Ultra patch tests had a good agreement in the detection of the 10 standard allergens that were tested.
