Indirect hydroxylation of aromatic rings using electrochemical methodsJournal of Applied Electrochemistry - Tập 16 - Trang 440-446 - 1986
R. P. Kreh, M. E. Tadros, H. M. Hand, M. P. Cockerham, E. K. Smith
Hydroxylation of activated aromatic rings has been acheved by anodic substitution followed by hydrolysis. The nucleophiles employed are anions of trifluoroacetic acid andp-toluenesulphonic acid, which result in ring-deactivation upon monosubstitution and are easily hydrolysed. High yields at high substrate conversion for the electrochemical step were obtained in dry acetonitrile solutions by const...... hiện toàn bộ

Nanosợi TiO2 được cấu tạo với cấu trúc bề mặt nano qua phương pháp thủy nhiệt ở nhiệt độ 180 °C. Những nanosợi này có bề mặt giống như ‘vết nứt’, tương tự như than cháy. So với những nanosợi có bề mặt tương đối mịn, những nanosợi giống than cháy có diện tích bề mặt riêng cao hơn. Bằng cách sử dụng những nanosợi này làm lớp tán xạ ánh sáng trong pin mặt trời nhuộm nhạy cảm hai lớp, các pin dựa trên...... hiện toàn bộ

Photocatalytic deposition of gold (Au) and silver (Ag) nanoparticles was investigated using jingle-bell-shaped silica (SiO2)-coated cadmium sulfide (CdS) nanoparticles (SiO2/CdS), which each had a void space between the CdS core and SiO2 shell, as a photocatalyst. A size-selective photoetching technique was used to prepare the jingle bell nanostructure of SiO2/CdS. Nanoparticles of Au and Ag were ...... hiện toàn bộ
The coulombic efficiency of zinc electrowinning in high-purity synthetic electrolytesJournal of Applied Electrochemistry - Tập 16 - Trang 654-662 - 1986
T. Biegler, E. J. Frazer
Measurements of coulombic efficiency (QE) for zinc electrodeposition were carried out under mass transfer-controlled conditions using a rotating disc electrode in synthetic acidic zinc sulphate electrolytes. At 25°C in 0.8 M ZnSO4+1.07 M H2SO4 prepared from reagent grade chemicals, the QE at an aluminium cathode was 95.7–97.6%. In order to study the influence of electrolyte purity on QE several pr...... hiện toàn bộ
Microstructural and segregation effects affecting the corrosion behavior of a high‐temperature Bi‐Ag solder alloy in dilute chloride solutionJournal of Applied Electrochemistry - Tập 51 - Trang 769-780 - 2021
Rudimylla Septimio, Clarissa Cruz, Bismarck Silva, Amauri Garcia, José Eduardo Spinelli, Noé Cheung
In electronic devices the solder joint is exposed not only to the air but also to moistures and other corrosive media such as chlorine and sulfur compounds. Bi–Ag alloys meet the melting temperature requirement to be classified as high-temperature solders, therefore, knowledge of corrosion behavior is important for a long-term reliability of Bi–Ag solder connections. However, corrosion studies of ...... hiện toàn bộ

Inhibiting property of nitrite intercalated layered double hydroxide for steel reinforcement in contaminated concrete conditionJournal of Applied Electrochemistry - Tập 50 - Trang 835-849 - 2020
Yuwan Tian, Cheng Wen, Gui Wang, Peichang Deng, Wanwan Mo
A nitrite intercalated layered double hydroxide (LDH-NO2) was suggested as an intelligent corrosion inhibitor to provide smart corrosion protection triggered by aggressive ions. A comparison of the inhibiting properties between NaNO2 and LDH-NO2 in the gradually contaminated concrete pore solution was investigated using electrochemical impedance spectroscopy, Mott–Schottky analysis and X-ray photo...... hiện toàn bộ
