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?

Food choices are increasingly perceived to be reflected in personal values, leading to the moralisation of one’s diet rather than an explicit focus on the physical nutrition received. Contemporary food culture often presents dietary options not only as they are, but as indicators of responsibility, self-control, compassion, acceptance, and virtue, and intrinsic values which one may use to indicate personality and belief reflecting behaviour. Consequently, food has become a symbolic medium through which individuals communicate aspects of their identity, beliefs, and moral character. However, these moral evaluations are not applied uniformly. Social expectations around food consumption are deeply influenced by gender, and this paper seeks to investigate the reasons behind women often being subjected to greater scrutiny in their choices, and being in many ways prodded, on what, how, when, and why they eat. The interrogation of choice is done by society on a certain section of society. Dietary restraint, eating “clean” and health-conscious choices are frequently associated with femininity, moral worth and identity. Indulgence, in this case, may be interpreted as a lack of self-control and failure of personal responsibility. In contrast, men’s eating behaviour is more commonly evaluated through ideals of performance, strength, autonomy and agency, which seems to be heavily influenced by society, through the conditioning received from gender-based social norms. These norms take effect for both genders in several aspects of studying media, social norms, the practice of these social norms and behavioural capacity to control their choices. This comparative study attempts to examine how identical eating behaviour is perceived differently depending on the gender of the individual. Drawing upon theories from moral psychology, Philosophical theories around gender, consumption, the sociology of food and personality studies. By investigating the intersection of food, morality, gender and identity, the study aims to contribute to a broader understanding of how everyday eating practices reinforce social norms, influence identity construction, and perpetuate gendered standards. This paper aims to contribute to gender studies and food consumption philosophy and psychology by attempting to determine the conditioning and reasoning behind one’s behaviour surrounding food, their relationship with food, their eating habits and the socio-cultural context these reasons arise from.

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).
