Jai Hind College (Marathi: जय हिंद कॉलेज) is an autonomous college in Mumbai, Maharashtra, India, affiliated to the University of Mumbai. It was established in 1948.In 2000, India Today named Jai Hind College as one of the best and most sought-after colleges in Mumbai city.It was established just after independence, by a small group of teachers who were displaced from D. J. Science College of Karachi, Sindh, Pakistan under the supervision of Dr. Mohinder-Miles Morton.
New quinoxaline-based TADF emitters show tunable orange-red emission (603–700 nm). The best emitter, Cz-PhQx4CN, achieves a maximum EQE of 9.9% in vacuum-deposited devices and 3.6% in solution-processed devices.
Ceramic neutron absorber materials like dysprosium titanate (Dy2TiO5) are gaining more attention in nuclear industries due to their advantages over conventional (n,alpha) absorbers. The high thermal neutron-absorption cross sections (sigma a) of five consecutive Dy isotopes (Dy-160 to Dy-164) and the low activity of their decay products make Dy2TiO5 a good choice for control rod material. The presence of other lanthanides as impurities in this material, which can come from the precursor, will affect its structural integrity and sigma a calculation. Hence, the chemical quality control (CQC) of Dy2TiO5 concerning the other trace lanthanides is indispensable. Ion interaction chromatographic separation of thirteen trace lanthanides from the chemically similar dysprosium matrix was carried out by a dynamically modified reversed-phase column using camphor-10-sulphonic acid and gradient elution with alpha-hydroxyisobutyric acid. Separate eluting fractions were collected for definite time intervals and analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES). The proposed methodology can detect individual other lanthanides in Dy2TiO5 matrix in the range of 0.6-4.0 mg kg(-1). A minimum of 20 mg kg(-1) other trace lanthanides in Dy2TiO5 solid can be quantified with a precision of 2-3%. The difficulty of determining other trace lanthanides in a lanthanide-rich Dy2TiO5 matrix is circumvented by an offline conjugation of ion interaction chromatography with ICP-OES.
Abstract The hasty expansion of Artificial Intelligence (AI)into subjects customarily regarded as intrinsic to human experience such as ethical and moral reasoning, affective stability and metacognitive processing has coincided with increasing academic engagement in the Spiritual Quotient (SQ). SQ includes distinct factors that help define this intelligence differently, such as ethical and moral orientation, depth and frequency of transcendent experience, and self-reflective meaning-making capacities. Simultaneously, human reliance on AI has increased substantially; recent estimates suggest that roughly 66% of the world intentionally engages with AI, at least periodically, with 15-16% of the global working age population engaging daily, asking questions that may relate to their personal life, including spiritual activities. Even though the presence of AI lacks consciousness, intentionality and lived experience, it does not reconfigure the location of AI within spiritual discourse. Instead, it solidifies its role as a mediating tool that may structure reflection without having the ability to embody it. As individuals increasingly turn to AI for reassurance, guidance, and cognitive outsourcing during periods of uncertainty or spiritual disconnection, questions arise regarding its influence on moral orientation and its hidden reflective depth. This paper aims to explore a conceptual framework drawn from philosophy and psychology, including Foucault’s notion of Power-Knowledge, the power dynamics present in human-AI relations, particularly structures and functions divided by thought, symbolized by doubt, fear, and existential uncertainty, that may be assisted through the use of AI’s pattern recognition and generalization of application of theories. By effectively differentiating between reflection and reassurance, and guidance and comfort, this paper conceptualizes AI as a tool for articulation rather than authority. It investigates whether AI meaningfully contributes either positively, neutrally or negatively impacting the development and course of a person’s spiritual journey and if it may include displacement of authentic introspection, which serves as a critical factor in an individual’s spiritual journey. The paper asks and attempts to answer the question: Does Artificial Intelligence aid in the enhancement of human spiritual quotient, or does it merely reshape the conditions under which spiritual reflection occurs? Keywords: Artificial Intelligence (AI), Spiritual Quotient (SQ), Morality, Spiritual Connection, Reflection, Human Agency, Moral Reasoning, Emotional Regulation, Intentional Engagement, Power Dynamics.
Affordable organic compounds with light-emitting properties offer a unique platform for addressing key challenges in organic electronics. This study primarily focuses on the molecular design and synthesis of a fluorescent emitter, 4-(tert-butyl)-N-(4-(tert-butyl)phenyl)-N-(4-(3,7,8-triphenylpyrazino[2,3-g]quinoxalin-2-yl)phenyl)aniline (t DPA-PyrQx), featuring an electron-donating bis(4-(tert-butyl)phenyl)amine group on a pyrazino[2,3-g]quinoxaline acceptor. The emitter exhibits high thermal stability, strong absorption and emission, and pronounced aggregation-induced emission (AIE), with its photophysical characteristics well supported by DFT calculations. The t DPA-PyrQx-doped OLED device was fabricated by using vacuum deposition and exhibited pure red emission, delivering a maximum external quantum efficiency (EQE) of 4.7% and Commission Internationale de l'Eclairage (CIE) coordinates of (0.67, 0.37).
The increasing amount of synthetic dye pollutants in industrial wastewater poses significant environmental and health concerns, creating an urgent need for efficient and sustainable remediation strategies. Herein, we report the fabrication of bimetallic Cu-Ni oxide-doped porous carbon nanofibers (Cu:Ni:PCFs) via block copolymer templating, electrospinning, and controlled pyrolysis. The hierarchical structures combined with uniformly dispersed copper and nickel oxide nanoparticles within the carbon matrix provided abundant active sites, enhanced surface charge modulation, and conferred multifunctional adsorption capabilities. The Cu:Ni:PCF adsorbent demonstrated excellent uptake of anionic MO and cationic MB, reaching Langmuir maximum monolayer adsorption capacities of 362 mg g-1 for MO and 323 mg g-1 for MB, showing enhanced localized single-point capacities under optimized pH environments. Rapid adsorption kinetics were observed, reaching equilibrium within 15 min. The kinetics data were best described by a pseudo-second-order model, indicating a strong adsorption interaction. The equilibrium data fit the Langmuir isotherm model, suggesting monolayer coverage on uniform adsorption sites. Notably, the adsorbent maintained its structural integrity and demonstrated high recyclability, retaining more than 90% of its initial adsorption capacity after five consecutive adsorption-desorption cycles. These findings underscore the potential of Cu:Ni:PCFs as a durable and efficient material for removing various dye contaminants from wastewater, representing a promising strategy for practical environmental remediation.
