Elements are reviewed using varying methods to check how efficiently they are working to make storage possible. An element like Li in LIBs can store up to 4 volts of power, the strongest behavior ever. It has earned huge attention in the commercial markets all across. Carbon with nitrogen can give a high charge capacity of 487 mAh/g with retention of over 80%. So, it has high-capacity load performance. Na-ion batteries are used for large-scale energy storage. These have up to 372 mAh/g storage capacity. K-ion batteries have fast ionic conductivity so these can have up to 710 mAh/g storage capacity. Ca-ion shows the impressive character toward its feature and gives storage upto 200 mAh/g. Cobalt batteries also show devoting behavior and can be stored up to a capacity 707 mAh/g at the current density of 90 mAh/g. Zn-ions show tremendous character in an aqueous medium. These batteries have a storage capacity of upto 810 mAh/g. Sulfur hybrid battery with lithium gives a reversible capacity of more than 900 mAh/g which is exceptional. All of these and more elements have very much promising behavior for storage with multiple cycles. This review article builds interest and trust in these elements.

Bagasse Fly Ash (BFA) is a rejected material of bagasse that is produced in the sugar industry after burning as a fuel. After this discovery, it is used as a cheap, effective and more reliable adsorbent with the highest elimination rate than activated carbon for various harmful heavy metals and pesticides at different factors like pH, contact time, adsorbent dose, adsorbate concentration, temperature, particle size by Batch and column studies. Pesticides and heavy metals have more adverse effects on human health as well as on the water bodies organisms like many systems as reproduction, urinary, neurological, circulatory, digestive, soil fertility fluctuations as acidity and basicity. Various techniques were utilized for the elimination of heavy metals and pesticides in the past with high expenses as well as difficult to manage. But in future, this review may help in new efficient adsorbent with high removal ability at a low price as well as easy to use than others adsorbents for the elimination of harmful heavy metals and pesticides from wastewater.

Most of synthetic dyes are toxic for the environment. On the other hand, natural dyes are ecofriendly and can replace synthetic toxic dyes. In the present studies, a natural dye was extracted from rinsed and grinded olive peel in 1:10 ratio (m/V) with water. Then, fabrics (wool and silk) were dyed with the peel extract by using different types of dulling and shining mordants (FeSO 4 , CuSO 4 , CoSO 4 , SnCl 2 , K 2 SO 4 , Al 2 (SO 4 ) 3 , ZnSO 4 and NiSO 4 ). The mordants have shown best results for wool at the acidic pH (4-5) and for silk at the basic pH (8-9). After dyeing wool (at 70-80ºC) and silk (at 100ºC) with olive peel extract, by simultaneous mordanting method, an interesting variety of beige, buff and khaki shades were obtained. Color fastness was noted by matching the dyed fabric color with grey scale. The colors of dyed fabric were again noted after its washing, pressing by iron, rubbing and light exposure. The fastness results were found quite satisfactory. The investigated procedure of natural dye extraction is eco-friendly, safe for the environment and a safe technique as it does not involve any organic solvent. The natural dyes can be satisfactory potential substitutes of the synthetic environmentally hazardous dyes.

Computer technology plays an active role in the development of the economic, educational, and social growth of a country. Following a sequential explanatory mixed methods research design, the primary purpose of the study was to comprehend the advantages of teaching science to grade 6 students via Computer Integrated Teaching (CIT) as compared to the lecture-based approach. This study also investigated if computer integrated teaching enhanced students learning and contributed to higher achievement scores. The research was conducted for 6 months, with a focus on grade 6 science instruction. The quantitative part of the study comprised experimental research with a sample size of 62 students. Experimental group students were exposed to a strong intervention program of CIT, whereas the control group was taught by traditional methods. The findings of the study show that the experimental group scored significantly higher marks in science theory and practical tests than the control group students. The qualitative findings of the study, based on focus group interviews, support the quantitative findings as students favored technology-based learning because of its vast potential.
