In the current study, Bismuth molybdate was synthesized using simple co-precipitation procedure, and their characterization was carried out by various methods such as FT-IR, SEM, and P-XRD. Furthermore, the photocatalytic degradation of Orange G (ORG) dye using synthesized catalyst under visible light irradiation was studied. Response surface Method was used for the optimization of process variables and degradation kinetics evaluated by modeling of experimental data. Based on the experimental design outcomes, the first-order model was proven as a practical correlation between selected factors and response. Further ANOVA analysis has revealed that only two out of six factors have a significant effect on ORG degradation, however ORG concentration and irradiation time indicated the significant effects sequentially. Maximum ORG degradation of approximately 96% was achieved by keeping process parameters in range, such as 1 g L−1 loading of catalyst, 50 mg L−1 concentration of ORG, 1.4 mol L−1 concentration of H2O2 at pH 7 and a temperature of 30 °C. Kinetics of ORG degradation followed the pseudo first order, and almost complete degradation was achieved within 8 h. The effectiveness of the Bi2MoO6/H2O2 photo-Fenton system in degradation reactions is due to the higher number of photo-generated e- available on the catalyst surface as a result of their ability to inhibit recombination of e- and h+ pair.

The emergence of a novel Corona virus (COVID 19) originated on December 19 from China. The city of Wuhan, the capital city of Hubei province, China, is responsible for an outbreak of respiratory illness known as COVID 19 and it has been rapidly spread across the world claiming millions of lives. The sudden outbreak of novel Coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2 or 2019‐nCoV), is a big concern for their speedy mitigation using the predictable treatment and creating its approach around the world. Researchers and doctors are in search of rapid diagnosis kit, drugs, and viral‐resistant personal protective equipment (PPE) to clinical diagnosis, medication, and prevent the spread of COVID 19. A rational approach with adaptability and broad viewpoint to challenge the growing pain could be overcome by the application of appropriate technology. The nanotechnology‐based approach can significantly serve the purpose of the current pandemic situation of COVID 19. But same time implementation of innovative and creative nanotech approach, there is a decisive need for the full knowledge of SARS‐CoV‐2 pathogenesis. Moreover, to defeat COVID 19, particularly nanotech‐based system with their viral inhibitory properties to increase the effective nanotech approach is essential. In this scenario, this review aims to summarize the past, present, and future of nanotech‐based systems that can be used to treat COVID 19, highlighting Nano‐based compounds. Lastly, the potential application of the different category of Inorganic Nanomaterials/Inorganic organic conjugate /hybrid system and their practical applicability as suitable means for inspiring against COVID 19 has also been discussed.

Background: Pregnancy and child birth are normal event in the life of women. Most pregnancy results in normal birth but any pregnancy can develop complication at any stage so timely provision of obstetric services is extremely important and to the care by a skill birth attendant. So knowledge, skills and practices of these are very important. In light of above the study was carried out with objective to assess the knowledge and practices of medical officer and paramedical staffs (staff nurses and ANM) regarding antenatal services, intra-natal services, postnatal services.Methods: A cross sectional study was conducted at first referral units (FRUs) of Agra district of Uttar Pradesh, India from June 2015–August 2016. Structured open ended interview schedule were use d to collect the desired information. Before commencing the interview, informed written consent were taken from respondents. All medical officer and all staff nurse, public health nurse and auxiliary nurse midwives (ANM) were included as study subjects. Data were collected by first author himself. A total of 25 medical officers and 30 paramedical staff were interview for the study.Results: Almost all the medical staffs (100%) have knowledge regarding antenatal care except minimum ANC visit (80%) as practice of ANC services concerned less than half of them doing it as routine, nearly 1/3rd of medical staff (32.0%) conducted or assists delivery (i.e. only LSCS) in routine practices.Conclusions: Knowledge about maternal health services was more among medical staffs than paramedical staffs. Paramedical staffs have less knowledge as well as practice about neonatal resuscitation and infection control measure. Only less than 1/3rd of medical staffs conducting or assisting deliveries.
