In this paper, employing a hydrothermal method, we synthesized Cu2O nanoparticles and Cu2O@C core–shell. The scanning electron microscope (SEM), X -Ray diffraction (XRD), dynamic light scattering (DLS) and zeta potential techniques were used for characterized of the Cu2O nanoparticles and Cu2O@C core–shell. The zeta potential values were obtained to be -11.16 mV and -0.88 mV for Cu2O and Cu2O@C, respectively

Study of the photocatalytic activity of Mn-doped ZnO nanocomposites depending on their morphology and structure with the variation of manganese concentration Surf. Interfaces (IF 3.724) Pub Date : 2020-12-26 Bharati Debi Biswas; Moushumi Dutta Purkayastha; Ekta Tiwari; Shanku Denrah; Mitali Sarkar; Gopala Krishna Darbha; Tapas Pal Majumder
Manganese doped zinc oxide (MZ) nanocomposites was uniquely synthesized using co-precipitation method. The photocatalytic activity of the synthesized MZ nanocomposites was studied under ultraviolet light irradiation by the photodegradation of malachite green (MG), a toxic organic dye. MZ3 (1:25) nanocomposite This show the best photocatalytic activity among the different molar ratios of Mn/Zn by studying

3D Printing-Assisted Fabrication of Microgrid Patterns for Flexible Antiadhesive Polymer Surfaces Surf. Interfaces (IF 3.724) Pub Date : 2021-01-10 Jaebum Sung; Hongyun So
Flexible antiadhesive polymer surfaces were fabricated using an array of microgrid patterns generated by three-dimensional (3D) printing. A disadvantage of the fused deposition modeling-type 3D printing (rough surface) was utilized to create casting molds with microgrid patterns. The shape of the microscale pattern was controlled by rotating the bottom epoxy mold where polylactic acid filaments were

Electronic interactions between graphene and cobaltite thin film La0.7Sr0.3CoO3 and its magnetic consequences Surf. Interfaces (IF 3.724) Pub Date : 2021-01-03 Zied Othmen; Riadh Othmen; Kais Daoudi; Michel Boudard; Antonella Cavanna; Ali Madouri; Pascale Gemeiner; Doru C. Lupascu; Meherzi Oueslati; Brahim Dkhil
We have successfully synthesized and transferred graphene (Gr) monolayers on top of epitaxial mixed valence La0.7Sr0.3CoO3 (LSCO) thin films. Raman spectroscopy reveals that Jahn-Teller (JT) modes associated with the oxygen octahedral distortions usually unobserved for bare LSCO are activated by the deposited graphene. The appearance of these JT modes in the Gr/LSCO heterostructure is attributed to

Spectroscopic, structural and morphological properties of spin coated Zn:TiO2 thin films Surf. Interfaces (IF 3.724) Pub Date : 2020-12-31 Prathvi; S Asha Bhandarkar; Akshayakumar Kompa; Dhananjaya Kekuda; Murari M S; Maksim P Telenkov; Nagaraja K K; Mohan Rao K
Herein we report on the spin coated thin films of Zn-doped TiO2 on glass substrates with various Zn concentrations (2 ‒8 at %). The structural, chemical, optical and morphological properties were investigated using X-ray diffraction (XRD), Raman spectroscopy, photoluminescence (PL), UV-Visible spectroscopy, X-ray Photoelectron Spectroscopy (XPS) and Field Emission Scanning Electron Microscopy (FESEM)
