Ewing Christian College (ECC), formerly Allahabad Christian College, is an autonomous constituent college of University of Allahabad, located in Allahabad, India.The college was established in 1902 by Arthur Henry Ewing, a prominent Presbyterian missionary, as an initiative of the East India Company.The college was conferred with the status of College with Potential for Excellence by the University Grants Commission in 2005 and accredited by the National Assessment and Accreditation Council (NAAC).
Heterocycle-containing liquid crystals are highly valued for their tunable physicochemical properties and potential in advanced technological and biological applications. Here, we report the design and synthesis of a homologous series of 5-phenylpyridine azomethines, (E)-3-hydroxy-4-(((5-phenylpyridin-2-yl) imino) methyl) phenyl 4-(alkyloxy) benzoates (5a-c), which exhibit thermally robust long range enantiotropic nematic mesophases, with alkyl chain length modulating phase transition temperatures and nematic ranges. Absorption spectroscopic studies revealed pi-pi* absorption bands at 280-281 & 360-367 nm and fluorescence at 431-438 nm. Electrochemical analysis of compound 5b showed a 1.595 eV band gap (HOMO -5.031 eV, LUMO -3.436 eV). DFT calculations confirmed optimized geometries and uniform electrostatic potential distributions, indicating electronic stability. Molecular docking study of 5a with BSA demonstrated strong binding through hydrogen bonds and hydrophobic interactions, suggesting significant biological affinity.
Lignin recovery from lignocellulosic material is a prominent solution to environmental concerns and problems and establishes more sustainable and competitive lignocellulosic biorefineries. Lignin has the potential to produce various commodity chemicals, biofuels, plastics, dyes, adhesives, concrete binders, foaming agents, lubricants, and nanomaterials, and is a commitment step for a safer and sustainable circular bioeconomy development. However, lignin valorization is hindered by a series of factors, i.e., heterogeneous nature, intrinsic recalcitrance, and the presence of strong intermolecular bonding and functionalities. Most of the lignin residue generated during cellulosic or pulp industries is combusted for electricity production in an uneconomic manner. Therefore, we have critically assessed and discussed the main constraints of novel strategies concerning lignin isolation and valorization, which is widely used in the landscape of lignocellulose biomass-based biorefining to reduce the dependency on fossil reserves and indirectly impacts the circular economy and lifestyle of people. Finally, this review highlights the integrated approach linked to enzyme-to-microbe, microbe-to-microbe interactions, or modified lignin fraction via employing metabolic engineering, discusses the commercial aspects of lignin in the market, and describes the future perspectives as well. Additionally, various advanced catalytic approaches under oxidative/reductive environments and hydrodeoxygenation are well explored, illustrating their influence on the selectivity of lignin depolymerization. The article will consolidate existing knowledge but also incorporate some novel perspectives for future advancement concerning lignin valorization in a sustainable way, which is a prerequisite objective for various biorefinery developments.
The chapter examines the integration of Agentic Artificial Intelligence (Agentic AI) and quantum computing, highlighting the emergence of quantum agents that enhance decision-making beyond classical limits. It reviews existing research in quantum machine learning and proposes a Quantum-Agentic Architecture (QAA) that combines classical AI with quantum processors to improve operational efficiency. Mathematical models for quantum-enhanced learning, including reinforcement learning equations, are presented, along with a comparative analysis of classical and quantum-enhanced agents in terms of complexity and convergence metrics. Experimental simulations show significant performance improvements in multi-agent environments. The chapter also addresses challenges such as noisy intermediate-scale quantum (NISQ) limitations and ethical considerations in the deployment of autonomous quantum intelligence systems.
The enhanced power graph of a group G is a simple undirected graph with vertex set G and two vertices are adjacent if they belong to same cyclic subgroup. In this article, we study the combinatorial properties of the enhanced power graph of non-abelian group G of order p^3 of exponent p^2 , where p is an odd prime. We also obtain the spectral properties of the enhanced power graph of the group G.
The aim of this paper is to give a formal meaning of universal commutator identities and to see as to how the structure of multiplicative Lie algebra on a group is a potential candidate to describe universal commutator identities. We introduce some higher Schur multipliers. We shall also introduce and study Steinberg and Chevalley Multiplicative Lie algebras, the multiplicative Lie algebras with commutator identities among the root vectors describing Lie product relations. Free multiplicative Lie algebra on Steinberg and Chevalley groups are discussed.
