Background: Silicon Photonics has been rapidly developing as a field. The primary reason for this is its lower operating costs and faster switching rates for use in big data centres. Instead of microns-wide copper lines to transmit signals, silicon photonic chips use waveguides, usually of silicon or silicon nitride. Photonic signals bypass the issues of resistive-capacitance lag (RC-lag) and resistive-heating encountered by copper lines. Additionally, a single waveguide may transmit multiple signals along different carrier wavelengths.

There is an increasing need for radiation-hardened electronics as space programs grow in number and scope. Scientific interest in long-term exploration, particularly in high-radiation environments such as Europa, as well as commercial interest in establishing permanent outposts, requires high tolerance of radiation effects. A flash memory device might survive for several years in low Earth orbit, but only a few days in orbit around Europa due to the extremely high levels of radiation encountered there. Meanwhile, commercial interests, including asteroid mining and building a base on the moon or Mars would require electronic systems that could survive for long periods …

Nucleic acid technology along with vast variety of nanomaterials has demonstrated a great potential in many applications from biosensing studies to molecular diagnostics, from biomedical and bioanalytical research to environmental analysis. Especially short single stranded (ss) DNA molecules, called oligonucleotides, are extraordinary biopolymers featuring diverse functionality on the nanoparticles thanks to their high degree of programmability, target-specific binding or cleavage, molecular recognition ability, structure-switching capability, and unique interactions at the bio-nano interfaces. Among those, there have been many biosensing applications utilizing ss DNAs and numerous nanomaterials through various detection techniques such as fluorometric, colorimetric or electrochemical methods. Although many groundbreaking …

Natural resources useful for the generation of energy are limited. The development of efficient materials capable of utilizing the abundant free solar radiation is of considerable interest. Utilization of otherwise wasted energy sources, including solar radiation, is a progressive step in the quest for sustainable energy. Solar radiation incident upon the earth’s surface exceeds current energy requirements and motivates scientists to investigate and develop functional devices and nanomaterials including light harvesting complexes (LHC) capable of capturing solar radiation for energy conversion and storage.

Despite the advance health care, devastating health conditions such as cancer and infectious diseases that affect populations worldwide are too often not diagnosed until morbid symptoms become apparent in the late phase. Obtaining an early and accurate diagnosis that reveal a hidden lethal threat before the disease becomes complicated may dramatically reduce the severity of its impact on the patient’s life and increase the probability of survival. For example, in the case of ovarian cancer, which is the fifth most common malignancy and the fifth leading cause of cancer mortality in women in the US, the 5-year relative survival is …
