Palmyra Palm(Borassus flabellifer Linn)is a native tree with various ecological,medicinal,economic,and sociological benefits from Asian countries.Palmyra Palm tree-based self-reliant lifestyle and Eco-friendly community living which leads to sustainable development can be called palmyra culture.For each component,Palmyra Palm is the most beneficial species that has economic and medicinal value that could sustain adverse climatic conditions and resist natural calamities.Non-edible,edible,and value add-based uses could be widely categorized into the utility of the plant.Palmyra palm tree is working like a non-stop biochemical factory,creates sugars and many otheruseful chemicals.It also produces many useful polymeric compounds such as pectin,cellulose,hemicelluloses,pentosanpolysulfate,polyphenols,and lignin.The current review gives an insight into the structural,biological,and polymeric elements of Asian palmyra. 展开更多

A simple,highly reproducible,and environmentally friendly method is a considered approach in generating renewable energy materials.Here,hydrogenated amorphous carbon(a-C)films have been successfully prepared from palmyra liquid sugar,employing spin-coating and spraying methods.Compared with the former method,the latter shows a significance in producing a better homogeneity in particle size and film thickness.The obtained films have a thickness of approximately 1000 to 100 nm and contain an sp^(2) hexagonal structure(~70%)and sp^(3) tetrahedral configuration(~30%)of carbons.The introduction of boron(B)and nitrogen(N)as dopants has created the local structural modification of bonding,inducing a slight change of electrical conductivity,electronic energy bandgap,and optical transparency near-infrared region.The obtained α-C film features a“green”semiconducting material. 展开更多

An a-C/a-C:N junction,which used palmyra sugar as the carbon source and ammonium hydroxide(NH4OH)as the dopant source,was successfully deposited on the ITO glass substrate using the nano-spraying method.The current-voltage relationship of the junction was found to be a Schottky-like contact,and therefore the junction shows the characteristic rectifiers.This means the a-C and a-C:N are semiconductors with different types of conduction.Moreover,the samples showed an increase in current and voltage value when exposed to visible light(bright state)compared to the dark condition,thereby,indicating the creation of electron-hole pairs during the exposure.It was also discovered that the relationship between current and voltage for the a-C/a-C:N junction sample formed a curve that satisfies the rule of the photovoltaic effect when exposed to visible light from a light bulb.The exposure of this sample to direct sunlight at AM 1.5 conditions produced a curve that meets the rules for the emergence of the photovoltaic effect with higher characteristics for the current-voltage relationship.Thus,the a-C/a-C:N junction sample is a solar cell successfully fabricated using a sample method and has a maximum efficiency of 0.0013%. 展开更多

Since the onset of conflict in Syria in 2011,several heritage sites have suffered partial or complete destruction.The ancient city of Palmyra,a UNESCO World Heritage Site since 1980,was placed on the List of World Heritage in Danger in 2013,alongside five other Syrian heritage sites.Between 2015 and 2017,Palmyra experienced the loss of nearly 40%of its historic buildings and landmarks.The site’s remote location and ongoing armed conflict pose additional challenges in accessing and preserving it.This paper introduces an interactive online platform employing 360°media to document and disseminate information about the world heritage site of Palmyra.The platform contributes to the safeguarding process of Palmyra,facilitating public engagement and interaction with the site.It also has potential applications for other sites in Syria and beyond.The platform allows users to explore both archival and current information of damaged historical monuments and buildings,revealing their layered histories before and after demolition.Employing interactive 360°media,similar to applications like Google Street View,the platform offers a reality-based digital environment.Users can virtually move into different buildings or follow specific pathways within the site,accessing archival information and documentation about particular monuments and buildings along their journey.This project serves as a unique informational resource for decision-makers and policy planners,aiding in the understanding of the site and the development of relevant strategies and recommendations.It also proves beneficial as an educational tool.The collective understanding fostered by this platform is expected to positively influence post-conflict restoration and reconstruction plans,making it an invaluable asset for research and educational purposes. 展开更多
