Detection of a large void (∼7 Mpc) is reported between the redshifts 2.16286 and 2.20748 in the Ly α forest of TOL 1038-2712. This void is centered near a foreground QSO TOL 1037-2704 which is at a distance ∼4.4 Mpc away from the void. The estimated probability for the void to occure by chance in front of the foreground QSO is few times 10 −3. Various implications of the void being produced by ...

Silicon batteries have attracted much attention in recent years due to their high theoretical capacity, although a rapid capacity fade is normally observed, attributed mainly to volume expansion during lithiation. Here, we report for the first time successful synthesis of Si/void/SiO2/void/C nanostructures. The synthesis strategy only involves selective etching of SiO2 in Si/SiO2/C structures w...

Low-dimensional copper interconnects are prone to void formation which takes place during the Cu-filling of narrow interconnect lines. These voids increase the electrical resistance of the interconnects which in turn results in an increase of the RC delay of the integrated circuit. Therefore, a fast and non-destructive method is needed, which will allow the detection of the voids in copper inte...

We study the possible magnetization of cosmic voids by void galaxies. Recently, observations revealed isolated starforming galaxies within the voids. Furthermore, a major fraction of a voids volume is expected to be filled with magnetic fields of a minimum strength of about 10 −15 G on Mpc scales. We estimate the transport of magnetic energy by cosmic rays (CR) from the void galaxies into the v...

Underwater Acoustic Sensor Network (UASN) comes with intrinsic constraints because it is deployed in the aquatic environment and uses the acoustic signals to communicate. The examples of those constraints are long propagation delay, very limited bandwidth, high energy cost for transmission, very high signal attenuation, costly deployment and battery replacement, and so forth. Therefore, the rou...
