“…The plausible reaction mechanism pathway proposed for the reaction is the same as in earlier reports ,. The Cu(0)NPs were generated in situ by rongalite from copper salt via single electron transfer . Then the Cu(0)NPs reacts with an alkyne to give a copper‐acetylide.…”

“…Further, we investigated the reaction mechanism of CuAAC catalyzed by CuNPs. Also we found in the literature that rongalite is capable of converting copper(II) chloride into nanoparticles such as Cu and Cu 2 O at higher temperature (70‐100 °C) . These findings arose our interest to analyze the composition of copper complex to know the type of copper species present and responsible for click reaction.…”

In Situ Generation of Copper Nanoparticles by Rongalite and Their Use as Catalyst for Click Chemistry in Water

A novel, efficient and green protocol for the copper‐catalyzed azide–alkyne cycloaddition (CuAAC) reaction by using copper nanoparticles (CuNPs), generated in situ by a green reducing agent, rongalite, is reported. Terminal alkynes reacted with benzyl, aryl and alkyl azides in the presence of copper nanoparticles and β ‐cyclodextrin (β‐CD) in water. The reactions exclusively generated the corresponding regiospecific 1,4‐disubstituted 1,2,3‐triazoles in good to excellent yields. Notably, in situ generation of copper nanoparticles does not require any additional stabilizing agents or special reaction conditions. β‐cyclodextrin plays dual role as a stabilizing agent as well as phase transfer catalyst. This protocol is also applicable for gram scale reactions.

“…Bakırın oksidasyonunu engellemek için ekstra işlemlerinin yapılmaması halinde bakırın uygulama alanları sınırlı kalmaktadır [30]. Bakırın uygulama anlarını genişletebilmek amacıyla çeşitli çalışmalar gerçekleştirilmektedir [32]- [36]. Gümüş ve altın elementinin yüksek maliyetli olması ve gümüşün iyon migrasyonun fazla olması basılı elektroniklerde kullanımını kısıtlamaktadır.…”

Bu araştırmanın amacı elektronik tekstil uygulamalarında kullanılan baskı yöntemlerinin incelenmesi ve bu baskı yöntemlerinde kullanılan farklı özelliklere sahip iletken mürekkeplerin işlem şartlarının, avantaj ve dezavantajlarının incelenmesidir. Araştırmada, iletken mürekkepler ile ilgili bir kavramsal çerçeve oluşturularak elektronik tekstiller alanında kullanımı ve önemi literatür açısından incelenmiştir. Çalışmada, gümüş içerikli iletken mürekkeplerin esnek malzemeler üzerine basılmasıyla, radyo frekansı tanımlama, elektromiyografi ve çeşitli sensör tasarımlarının yapıldığı görülmüştür. Serigrafi ve inkjet baskı teknikleri en çok kullanılan baskı teknikleri olarak değerlendirilmiştir.This study was conducted to investigate printing techniques used in electronic textile applications and to examine the application conditions, advantages and disadvantages of the conductive inks used in these printing processes. This research is a conceptual framework designed to examine conductive inks within the scope of electronic textiles and their importance. In the study, it is seen that by printing of silver doped conductive ink on flexible materials, radio frequency identification (RFID, electromyography (EMG) and variety of sensors are designed. It was evaluated that screen printing and inkjet printing techniques are most familiar printing applications.

“…Synthesis of Cu-NPs through chemical methods under the surrounding atmosphere, with Cts as stabilizers, hydrazine as a reducing agent and ascorbic acid as an antioxidant (Usman et al, 2012). In this study, rongalite was used as a novel reducing agent to overcome these limitations for synthesis of the Cu-NPs (Patil, Ryu and Kim, 2018).…”

“…However, research (Patil, Ryu and Kim, 2018) has not been written about the economic evaluation of copper nanoparticle synthesis on an industrial scale, so to provide that data, we will present economic evaluation data in this report. The results of these studies encourage further research into the synthesis of copper nanoparticles.…”

The purpose of this study was to analyze the Economic Evaluation in the Production of Copper Nanoparticles (Cu-Nps) using Rongalite as Reducing Agent, an experimental method carried out in the perspective of engineering and economic evaluation. Technical analysis was performed using simple mass balance analysis, while economic evaluation was carried out using several economic parameters, including PBP, BEP, and CNPV. To support the analysis, all data is taken based on the available online shopping web. All calculations are carried out in ideal conditions for 20 years of production. Economic evaluation is carried out by giving 5 conditions (0%, 20%, 40%, 60%, and 80%) to the variable price variations in cost, sales, fixed cost, and labor. Economic evaluation analysis results show that price variations can affect the CNPV / TIC (%) curve to Life Time (year). In the variable cost, fixed cost, and labor variable price curve it is found that the condition of 0% is the highest curve compared to other conditions. While in sales price variations, the 80% condition is the highest curve. In conclusion, all price variation curves show profit. The benefits of this research are the large-scale economic evaluation data on Cu nanoparticle production.
