Nanotechnology is widely used for the manufacturing of photovoltaic (PV) solar cells. Applications of solar technology are based in two forms; lithium-ion and lead-acid. These cells and batteries have the capacity to store a large amount of energy longer than other ordinary batteries. The mechanism for manufacturing solar cells usually arises from the combinations of layers of single-molecule thick sheets of graphene and molybdenum diselenide. In this fact, one of common example is the fine coating of graphene with zinc oxide nanowires. Solar based cells are incorporated into the modified forms for increasing their synthetic applications. These modified forms are copper indium selenide sulfide quantum dots. Perovskite solar cells are dominating in the scientific community due to their advantages and cheap sources of solar energy. These perovskite solar cells are also composed of different metals and other combinations in order to make them functional for different purposes. The most widely implemented metals are germanium, antimony, titanium and barium. Tin (Sn)-based perovskites allow the movement of ions and electrons and significantly in the surrounding environment. There is also need in the future for valuable and mechanical designing for nanotechnolgy and their usage in industrial and commercial applications.

Balangu (Lallemantia royleana) is a member of the Lamiaceae or Labiateae family. In Pakistan commonly called Tukhmalanga. This valuable medicinal plant is indigenous to tropical Asia, including India, Afghanistan, and Pakistan. The chemical analysis of Lallemantia royleana seed showed that the seeds contained: protein 25.60%, fat 18.27%, fiber 1.29%, alkaloids, anthraquinones, flavonoids, glycosides, pholobtannin tannins, volatile oils, mixed fatty acids and terpenoids. It exerted many pharmacological effects included antimicrobial, antioxidant, antidepressant, anxiolytic, sedative, antiemetic, hypolipidemic, protective and many other pharmacological effects. The current review discussed the Lallemantia royleana as a beneficial medicinal plant. It can be a good remedy for skin disease. Further screening for phytochemicals should be carried out in search of novel therapeutic compounds.

This study carried out to determine the impact of school physical facilities on students’ academic performance in senior secondary schools in Aba Education Zone of Abia State. A descriptive survey research design was adopted by the study with the population of 47 respondents (29 male 18 female teachers) sampled purposively from the 11 secondary schools in Aba educational zone of Abia State. Two research questions and two null hypotheses guided the study. The instrument for data collection was a structured 27-items statement questionnaire developed by the researchers after an extensive literature reviewed sectioned A & B with rating scales of Strongly Agree (SA), Agree (A), Disagree (D) and Strongly Disagree (SD) assigned the numerical values of 4, 3, 2 & 1 respectively. The instrument was validated by research experts while the reliability index of 0.87 was obtained using Cronbach Alpha reliability estimate. Mean and standard deviation were used to answer the two research questions while the null hypotheses were tested using t-test statistics at .05 level of significance and appropriate degree of freedom. The result of the analyses revealed that library as a school physical facility has great impact on the students’ academic performance in senior secondary schools in Aba Education Zone. It was afterwards recommended that adequate school physical facilities should be provided by appropriate authorities to ensure effective teaching and learning activities. It is believed that if the facilities are available and adequate, there would be effective performance among students in senior secondary schools in Aba Education Zone of Abia State.

Productivity, Work Pressure, and Wellness Are Related
The research conducted in this article was used to prove that work stress has a measurable impact on wellness and productivity of professionals. Research was conducted by placing typical work patterns of subjects in perspective, identifying sources of data for various aspects of the subject’s interactions with work during the day, classifying and organizing collected data based on criteria related to time, groups, etc. and then used to draw conclusions via corelation of work stress periods with periods of productivity. The research concluded that work stress does in fact have a measurable impact, not just on individual subjects, but also has long term consequences for organizations/groups.

In recent years, studies have placed a greater emphasis on the scientific evaluation of historical plant-based medications, as well as the examination of various plant parts for medicinal and pharmacological significance. In light of cultural histories and ancient medicine from previous decades, which have continued to promote the healing benefits of plants and their extracts, the medicinal values of plants cannot be overstated. Nutraceuticals are the use of therapeutic properties of plants or plant parts to prevent and control illness. The Zingiberaceae family includes Curcuma longa (Turmeric), which is one of the most innovative nutraceuticals. It is widely grown and consumed in India and Asian countries as a shelf-life enhancer and preservative, aromatic, and coloring ingredient. It possesses anti-glycemic, antioxidant, anti-inflammatory, anti-carcinogenic, and anti-viral properties, among other health advantages. For millennia, Curcuma longa has been regarded safe to use as a spice and seasoning.

Severe acute respiratory syndrome coronavirus 2 that causes coronavirus disease 2019 (COVID-19) is changing at a rapid pace due to accumulated mutations in the viral genetic code over time. As new variants of the virus continue to emerge and replace previous versions of the variants, therapeutics and vaccines are being constantly monitored and reviewed for their efficacy against the new strains. With the surge in new omicron sub-variants across the nation, U.S. Food and Drug Administration issued emergency use authorization to a new monoclonal antibody therapy called bebtelovimab replacing the previous sotrovimab that was effective against Omicron BA.1. The main objective of the paper is to review the current treatment options available to treat non-hospitalized mild-to-moderate COVID-19 caused by the new omicron sub-variants BA.2, BA.4, and BA.5. Scientists, pharmaceutical companies, and researchers have been proactive in conducting randomized, double-blinded, placebo-controlled clinical trials to test the safety and efficacy of therapeutics in managing COVID-19 in addition to testing the vaccine efficacy against new strains. The paper focuses on reviewing the results of these randomized controlled trials. The oral antiviral options paxlovid and molnupiravir, and intravenous (IV) bebtelovimab continue to show their efficacy against the new sub-variants BA.4 and BA.5. It is important for everyone to stay well-informed of the new treatment options and only opt for those medications that are currently authorized for use in treating mild-to-moderate COVID-19.
