In this report, to tackle the thermal fluorescent quenching issue of II-VI semiconductor quantum dots (QDs), which hinders their on-chip packaging application to light-emitting diodes (LEDs), a QD-ZnS nanosheet inorganic assembly monolith (QD-ZnS NIAM) is developed through chemisorption of QDs on the surface of two-dimensional (2D) ZnS nanosheets and subsequent assembly of the nanosheets into a...

ing dielectric permittivity and loss tangent of embedded passive materials. The measurements are made in an APC-7 coaxial configuration where the test specimen represents a load terminating an air-filled coaxial transmission line. The method is suitable for testing high dielectric constant (high-k) polymer-composite materials having nominal thickness of 1 μm to 300 μm at frequencies of 100 MHz ...

Surface modification of titanium (Ti) implants are extensively studied in order to obtain prominent biocompatibility and antimicrobial activity, especially preventing implant-associated infection. In this study, Ti substrates surface were modified by graphene oxide (GO) thin film and silver (Ag) nanoparticles via electroplating and ultraviolet reduction methods so as to achieve this purpose. Mi...

To evaluate the significance of thin-film composite membrane surface morphology on water productivity, flat-sheet experiments were conducted with silicon dioxide, titanium dioxide, and cerium dioxide nanoparticles. The polyamide thin-film active layer exhibited a valley and ridge morphology that was directly related to the surface roughness, and was found to contribute to particle accumulation ...
