The second method is the spray coating method, which was put forward by the Jesse Zhu research group. Briefly, it consists of several steps as follows: the mixture preparation of submicron PTFE particles, hydrophobic fluoric amorphous nanosilica and sol–gel (as binder), followed by spraying with a spray gun driven by an air supply and, finally, coating curing.

MACOM Silicon Photonics (SiPh)
Silicon photonics is expected to be the most scalable optical transceiver technology available while delivering lowest cost per bit for 100G and 400G. Working in conjunction with value-added foundry partners, we''re using mature photonics design and manufacturing processes to deliver state-of-the-art device performance.
Exfoliated single-crystalline GaN films grown on graphene …
The graphene, which is epitaxially grown on a silicon carbide substrate, serves as a reusable template for growing III-nitride films. The resulting GaN-based multi-quantum-well structures are quite flexible -- flexible enough, in fact, that the blue-emitting LEDs that researchers fabried were actually flexible LEDs transferred to plastic tape.
Types of Building Materials Used in Construction and …
Building material is any material used for construction purpose such as materials for house building. Wood, cement, aggregates, metals, bricks, concrete, clay are the most common type of building material used in construction. The choice of these are based on their cost effectiveness for building projects. Many naturally occurring substances, such as clay, sand, wood and […]

Using the THz-REEF technique, high-resolution broadband spectra of water vapor and 4-Amino-2, 6-dinitrotoluene (4A-DNT) were obtained from 0 to 7 THz and 0 to 1.5 THz ranges, respectively. The 4A-DNT spectra compared favorably with electro-optic sampling, wherein an electro-optic crystal (300 µm thick 110> gallium phosphide) is used to measure the time-domain terahertz waveform via the
