ABSTRACT

Photocatalysis represents a unique class of chemical transformations. It utilizes the energy delivered by light and drives reactions that are difficult, sometimes even impossible, to carry out in dark. When used for thermodynamically uphill reactions such as photosynthesis, photocatalysis promises a sustainable solution to large scale solar energy storage. Despite the longstanding interest in this process and research efforts, existing photocatalysis demonstrations are limited to academic laboratory settings. Chief among the reasons for the slow progress is the lack of suitable photocatalysts materials for large scale applications. For the purpose of effective light absorption, charge separation, and charge transfer, a large number of photocatalytic materials, including conventional semiconductors and emerging photoelectronic materials such as nanoscale plasmonic metal particles, quantum dots, and 2D materials, have been studied.¹

ABSTRACT

This review paper purpose is the ‘Queen of herb’’ means holy basil/Tulsi is how to showing it Antimicrobial activity by using different type of method. This paper also study the pharmaceutical used of Tulsi & its Pharmacological activity of Tulsi like. Antimicrobial activity, Antifungal activity, Anti-inflammatory& Analgesic activity. It is main symbol of the Hindu region tradition this is plant having unique odor found in the semitropical and tropical country. In the world. This is plant mainly used for reducing the cough. Holy basil is ancient Hindu scriptures, Tulsi occupies the supreme position among the herb so that it referred to as “MOTHER”. It has been used Ayurveda and siddha practices for it’s supposed treatment of diseases. It having medicinal her that belong to the mint family and is found in 150 different worldwide. Tulsi has been used in thousands of years in Ayurveda for its diverse healing properties special about this plant is apart from being considered holy Tulsi is also reserved as great healer

ABSTRACT

An analytical methodology for the simultaneous determination of seven pharmaceuticals and two metabolites belonging to the non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics therapeutic groups was developed based on off-line solid-phase extraction and ultra-high performance liquid chromatography coupled to tandem mass spectrometry ¹ (SPE–UHPLC–MS/MS). Extraction conditions were optimized taking into account parameters like sorbent material, sample volume and sample ^1,2 PH. Method detection limits (MDLs) ranging from 0.02 to 8.18 ng/L were obtained ^2,3. This methodology was successfully applied to the determination of the selected pharmaceuticals in seawater samples of Atlantic Ocean in the Northern Portuguese coast. All the pharmaceuticals have been detected in the seawater samples, with pharmaceuticals like ibuprofen, acetaminophen, ketoprofen and the metabolite hydroxy ibuprofen being the most frequently detected at concentrations that can reach some hundreds of ng/L ⁴.
