A Minisci-type borylation of unprotected adenosine, adenine nucleotide, and adenosine analogues was successfully achieved through photocatalysis or thermal activation. Despite the challenges posed by the presence of two potential reactive sites (C and C) in the purine motif, the unique nucleophilic amine-ligated boryl radicals effortlessly achieved excellent C site selectivity and simultaneously avoided the formation of multifunctionalized products. This protocol proved effective for the late-stage borylation of some important biomolecules as well as a few antiviral and antitumor drug molecules, such as AMP, cAMP, Vidarabine, Cordycepin, Tenofovir, Adefovir, GS-441524, etc.

Article Synopsis
  • Ionic liquids (ILs) are unique liquid salts known for their low melting points, ionic nature, and customizable properties, making them valuable in fluorescence sensing technologies.
  • This paper reviews various applications of ILs in fluorescence sensors, categorizing them based on the target materials like metals, explosives, and organic compounds.
  • The effectiveness of these sensors hinges on careful design to ensure they are specific and sensitive, with performance influenced by the chemical properties of the IL, the fluorophore used, and how they interact with the analyte being analyzed.

A combination of mineral nutrients and plant growth regulators should be assessed to improve crop performance under various abiotic stresses. There is a need to include plant growth regulators in fertilization regime of various crops along with essential mineral nutrients, especially when they are irrigated with polluted water with higher levels of heavy metals. The performance of pea was evaluated under cadmium (Cd) stress coupled with potassium (K) and jasmonic acid (JA) supplementation.

Due to climate change, temperature in late February and early March raised up which cause heat stress at reproductive stage (terminal growth phase of wheat crop) which has become the major causative factor towards low wheat production in arid and semiarid regions. Therefore; strategies need to be adopted for improving terminal heat stress tolerance in wheat. In this study, we assessed whether foliar application of silicon (Si) (2 and 4 mM) at terminal growth phase i.

Wheat is an important global staple food crop; however, its productivity is severely hampered by changing climate. Erratic rain patterns cause terminal drought stress, which affect reproductive development and crop yield. This study investigates the potential and zinc (Zn) and silicon (Si) to ameliorate terminal drought stress in wheat and associated mechanisms.

In metamaterials, metallic nanowires are used for creating artificial materials to functionalize them for various nanophotonics applications. Strong polarization-dependent response coupled with complex dielectric function at optical frequencies gives additional degrees of freedom to achieve scattering, absorption, and other benefits that go much beyond what is possible with conventional materials. In this paper, we propose an extended cylindrical wave impedance approach at optical frequencies to model the internal and external impedance of the metallic nanowire.

Article Synopsis
  • Salt stress negatively impacts potato growth and yield, prompting a study on the effectiveness of salicylic acid in mitigating these effects during cultivation under high salinity conditions.
  • Salicylic acid improved the performance of both potato cultivars tested, with N-Y LARA showing greater responsiveness compared to 720-110 NARC, suggesting genetic differences in salt tolerance.
  • The application of salicylic acid resulted in better antioxidant activity, improved water relations, and increased potassium availability, ultimately correlating with enhanced tuber yield, making it a recommended treatment for potatoes in saline environments.
