Surface tremors help explore new 2D semiconductor

Something new to explore

Functional genomics in plants has been facilitated greatly by the use of plant viruses to carry segments of host genes that can then promote the silencing of the RNAs expressed from the corresponding host genes; a process called virus-induced gene silencing (VIGS). The silencing of genes in filamentous fungi is either technically more problematic or labor-intensive, especially if transgenic pla...

Directing semiconductor nanorod assembly into 1D or 2D supercrystals by altering the surface charge.

Coulomb repulsion due to the surface charge on semi-conductor nanorods works against the dipole-dipole attraction that tends to direct the nanorods to self-assemble; the nature of this self-assembly for CdSe nanorods can be thus altered by pyridine washing, which charges the rods surface--thereby allowing the Coulomb repulsion to tailor the alignment.

Semiconductor surface plasmon sources.

Surface-plasmon polaritons (SPPs) are propagating electromagnetic modes bound at a metal-dielectric interface. We report on electrical generation of SPPs by reproducing the analogue in the near field of the slit-doublet experiment, in a device which includes all the building blocks required for a fully integrated plasmonic active source: an electrical generator of SPPs, a coupler, and a passive...

A new 2D image compression technique for 3D surface reconstruction

Image compression is one of the important techniques used today for image and video transmission. There are many types of image compression techniques are used these days; one of them is JPEG technique. In this research, we introduce a new idea for applying the JPEG technique with Discrete Wavelet Transform (DWT) for high-resolution images. Our image compression algorithm consists of; firstly, ...
