Many high-Tc superconductors, Iron based superconductors and other recently discovered superconducting materials shows the signature of existence of a strange Pseudo Gap above the superconducting transition temperature. Various experimental techniques such as NMR, Tunneling and ARPES suggest that pseudo gap does not change with temperature. As evidenced from these experimental results, the Pseudo gap possess the d-wave pairing symmetry similar to superconducting energy gap. The physical properties shows unusual behavior in the non-superconducting state where pseudo gap exist. Based on experimental evidences we argue about the origin of pseudo gap in these superconductors. Although a complete understanding of mechanism is lacking, the existence of preformed cooper indicated by various experimental probes pairs seems to be responsible for the origin of Pseudo gap.

Self assembled adlayers of conjugated organic molecules on metallic substrates have gained considerable attention due to promising applications in optoelectronic devices based on conjugated molecules. The performance of molecular electronic devices is significantly influenced by interfacial electronic properties at metal-molecule interfaces. The review summarizes significant findings of photoemission spectroscopy together with low energy electron diffraction and X-ray absorption spectroscopy utilized to characterize electronic properties at the metal-molecule interfaces, providing vital information about the charge transfer and charge injection barriers. The adsorption of transition metal complexes on surfaces with and without graphene buffer layers is another crucial issue for their interconnection between electro-magnetic properties. Therefore, fine characterization of these interfaces is mandatory in their applications.. Recent results of phthalocyanines deposited on ferromagnetic metal surfaces and graphene buffer layers revealed a substrate-molecular coupling mechanism, which shows a delicate interaction between long-range as well as local chemical bond.

The 2019 novel corona virus also known as severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) causing corona virus disease 2019 (COVID-19) is spreading rapidly since its earliest incidence in Wuhan, China to 201 countries within a short period. The exponential growth in the morbidity and mortality rate world wide due to the highly contagious nature of this virus and due to the absence of effective treatment and vaccine has worsened the situation.

Global Respiratory illness outbreak COVID-19 is a new public health crisis threatening humanity across the globe with the emergence and spread from central China in late 2019. The virus originated around Wuhan, Hubei province, China in December 2019 in bats and was transmitted through unknown intermediary sources to humans. The clinical presentation of viral infection ranges from asymptomatic to severe pneumonia with acute pulmonary distress syndrome is designated as COVID-19. WHO has characterized the disease as a pandemic due to its severity, as well as the shifting of epidemic zones across the globe from epicentre zone, China through a different stage of transmission by contact or inhalation with infected droplets and the incubation period, varies between 2 - 14 days. Treatment is essentially supportive; the effective role of antiviral agents is yet to be established and secondly without knowing the entire genome sequence of COVID- 19, no drug or vaccine can be effectively administered. Prevention entails home isolation of suspected cases and those with mild illnesses and strict infection control measures at hospitals that include contact and droplet precautions. The highest risk of healthcare-associated transmission is in the absence of standard precautions, when basic infection prevention and control measures for respiratory infections are not in place, and when handling patients where COVID infection is yet to be confirmed. The pandemic acceleration of COVID-19 indicates that the initial sporadic spreading worst hit the epicentre, China. But later on, epidemic zone shifts to nearly all continents.
