    Carbon paste electrodes modified by ferrocene (Fc) were used for electrocatalytic oxidation and determination of dopamine. The modified carbon paste electrode shows excellent electrocatalytic activity toward the oxidation of dopamine (DA) in a phosphate buffer solution (pH = 6.0). A anodic oxidation of DA (in pH = 6.0) at the Fc-modified carbon paste electrode occurred at low overpotential (0.18 V vs. Ag ‌ AgCl), and treatment of the voltammetric data showed that it was a purely diffusion-controlled reaction with the involvement of one electron in the rate-determining step. The mechanism for the interaction of DA at the Fc modified CPE is proposed. The rate constant k\u27, transfer coefficient α for the catalytic reaction and the diffusion coefficient of DA in the solution, D, were found to be 6.92×10–2 cm s–1, 0.71 and 1.41×10−5 cm2 s−1, respectively. The interference of ascorbic acid was investigated and greatly reduced using sodium tetraphenylborate incorporated modified carbon paste electrodes.</p

    The understanding of electrocatalytic activity and poisoning resistance properties of Pt and Pd nanoparticles, recognized as the best electrocatalysts for the ethanol oxidation reaction, is an essential step for the commercialization of direct ethanol fuel cells (DEFCs). In this paper, mono and bimetallic Pt and Pd nanoparticles with different atomic ratios have been synthesized to study their electrocatalytic properties for an ethanol oxidation reaction in alkaline solutions. The different nanoparticles were physiochemically characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The electrochemical characterization was performed by cyclic voltammetry and chronoamperometry measurements. The electrochemical measurements indicate that Pt nanoparticles have much higher electrocatalytic activity for ethanol oxidation than Pd nanoparticles. The studies with bimetallic PtPd nanoparticles showed a significant impact of their composition on the ethanol oxidation. Thus, the highest electrocatalytic activity and poisoning resistance properties were obtained for Pt3Pd2 nanoparticles. Moreover, this study demonstrates that the poisoning of the catalyst surface through ethanol oxidation is related to the prevalence of the acetaldehyde–acetate route and the polymerization of acetaldehyde through aldol condensation in the alkaline media.This research was funded by Ministerio de Ciencia e Innovación (Spain) grant number PID2019-105653GB-100), Generalitat Valenciana (Spain) grant number PROMETEO/2020/063, and the University of Zanjan Research Council

    Abstract. The focus of business units on maximizing profits, tackling competitive challenges, emphasizing short-term outcomes, and delivering diverse accounting services has put accountants in a climate of conflict and pressure that has led to unethical outcomes for them. Accounting plays a key role in the social and economic progress of a nation. Ethical standards are a hallmark of the accounting profession. The key question is how the ethical approaches of accountants have an impact on the disclosure quality of corporate social responsibility information. The main purpose of this study is to test a modified Multidimensional Ethics Scale (MES) to measure the ethical evaluations of accountants and financial managers todetermine the effects Accountants’ Ethical Decision Making on the CSR. Overall, The results show that there is a positive and significant relationship between the ethical approaches of accountants and the quality of disclosure of accounting information.Keywords: Ethics, Multi dimensional, Ethics Scale, CSR, ICSR

    Introduction This study aimed to compare the efficacy of ibuprofen, Novafen, mefenamic acid (MA), and celecoxib for pain relief in patients with symptomatic irreversible pulpitis prior to emergency endodontic treatment. Materials and Methods: This clinical trial was conducted on 120 patients with moderate to severe pain due to symptomatic irreversible pulpitis seeking emergency endodontic treatment. The patients were randomly divided into 4 groups to receive Novafen, MA, Celecoxib, and ibuprofen. The pain score of patients was measured before and 1 hour after analgesic intake using a visual analog scale (VAS). The success of analgesic treatment was analyzed by the binary logistic regression model. Results: A total of 117 patients including 76 females and 41 males with a mean age of 30.29 years completed the study and were statistically analyzed. Ibuprofen had the highest analgesic efficacy followed by Novafen, and caused a significantly greater reduction in pain score compared with MA and celecoxib [OR (Ibuprofen vs MA)=1.28, OR (Ibuprofen vs Celecoxib)=3.74, OR (Novafen vs MA)=2.94, OR (Novafen vs Celecoxib)=2.94, P&lt;0.05]. Ibuprofen and Novafen had no significant difference in analgesic efficacy (P&gt;0.05). Baseline pain score was a predictive factor for the success of analgesics (P&lt;0.05). The success of analgesic treatment decreased by 0.68 times with each unit increase in pain score (P&lt;0.05). Gender and age of patients had no significant effect on success of analgesics (P&gt;0.05). Conclusion: Both ibuprofen and Novafen can serve as the analgesics of choice for pain relief in patients with symptomatic irreversible pulpitis with moderate to severe pain when emergency endodontic treatment cannot be immediately performed
