Green route to fabrication of Semal-ZnO nanoparticles for efficient solar-driven catalysis of noxious dyes in diverse aquatic environments

This work successfully demonstrates a sustainable and environmentally friendly approach for synthesizing Semal-ZnO nanoparticles (NPs) using the aqueous leaf extract of Bombax ceiba L. These NPs exhibit an absorption peak at approximately 390 nm in the UV-visible spectrum and an energy gap (Eg) of 3.11 eV. Detailed analyses of the morphology and particle size using various spectroscopic and microscopic techniques, XRD, FE-SEM with EDS, and HR-TEM reveal crystallographic peaks attributable to the hexagonal phase, with an average crystal size of 17 nm. The Semal-ZnO NPs also exhibit a notable photocatalytic efficiency for degrading methylene blue (MB) and methyl orange (MO) under sunlight in different water samples collected from diverse natural sources, indicating that they are promising photocatalysts for environmental remediation. The photocatalytic efficiency of the biofabricated Semal-ZnO NPs is impressive, exhibiting a photodegradation rate of up to 99% for MB and 79% for MO in different water samples under exposure to sunlight. The novel phytofabricated Semal-ZnO NPs are thus a beacon of hope for the environment, with their desirable photocatalytic efficiency, pseudo-first-order kinetics, and ability to break down noxious dye pollutants in various aquatic environments

DERMATOGLYPHIC PATTERNS AND ACADEMIC PERFORMANCE OF COLLEGE STUDENTS: A RELATIONSHIP?

Dermatoglyphics is the study of patterns of epidermal ridges and these patterns do not change through entire life and thus are unique features of identification. This study aimed at finding a relation between the dermatoglyphic patterns and the academic performance among the physiotherapy students of Teerthanker Mahaveer University with the sole intent of using these patterns for categorising students into above average, below average and average performance. A total of 100 physiotherapy students of 3rd and 4th year were included in the study (31 male and 69 female). The students were categorised as average, above average and below average performers on the basis of cumulative percentage of end term exams of last 2 years. The dermatoglyphic patterns were recorded using the flat-bed scanner method. Students with above average academic performance had prevalence of loop pattern (Whorls 37 %, loops 58 %, arches 4 %) while students with below average academic performance had prevalence of whorl pattern (Whorls 58 %, loops 39 %, arches 2 %) and a negative correlation of ‘atd’ angle to the academic performance was observed. Thus, these patterns may be used as adjunct tool for identifying and differentiate individuals on the basis of academic performance so that different methods and educational strategies may be made a part of the curriculum for enhancing the performance of low scoring individuals

Gluten free approach of biscuits preparation

Replacement of gluten is a challenging issue in preparation of the bakery products. The present work aimed to develop gluten-free biscuits by using gluten-free flours like rice, sorghum, and corn in different ratios (0, 25, 33.33, 50, and 100%). The quality of the prepared biscuits was analyzed based on different physical, chemical, and nutritional parameters. It was found that there was a significant (p < 0.05) effect of flour ratio on the chemical and nutritional properties of the biscuits. Sample with an equal ratio of different flours was found to be good in terms of total sugar, reducing sugar, protein content, fat content, moisture content, ash content, and some physical properties like spread ratio, volume, and densities. Sensory analysis was also performed and found that the biscuits are high in overall acceptability and a sample with an equal ratio of flours was found to be highly accepted. It can be suggested that whole wheat flour can plausibly be substituted by gluten-free soy, corn, and rice flour

Concentration-Guided Visual Detection of Multiphase Aliphatic Biogenic Amines through Amine–Phenol Recognition Using a Dual-State Emitter

Intermolecular amine–phenol interactions are largely recognized as unique models with diverse supramolecular interactions. However, fluorescence (FL) variations originating from such interactions are rare. Herein, FL changes are well realized from amine–phenol interactions to identify an important biomarker, biogenic amines (BAs). A simple, inexpensive, and thermally stable anthracenylphosphonate is linked with 2,2′-biphenol to design a functional dual-state emitter. Among the various amines tested, this emitter displays superior sensitivity with the lowest possible limit of detection as 5.8–9.7 ppb with aliphatic polyamines such as 1,3-, 1,4-, 1,5-, and 1,6- diamines and spermidine in the solution phase. Fast, on-spot detection of the BA vapors was visually conducted through a notable high-contrast change from blue to yellow emission in the solid state. FT-IR, 1H/31P NMR, and mass spectroscopic studies identify the ground-state amine–phenol interactions. The failure in BA detection with the 2,2′-dimethoxy-biphenyl-linked analog verifies the role of amine–phenol interactions. Mechanistic studies determine amine–phenol interactions in the ground and excited states. The molecular structure and packing of the doubly twisted probe are documented with a substantial void space facilitating close contact of the BAs with the strong amine–phenol interactions desired for efficient detection. Finally, this probe governs the freshness of a piece of Catla catla fish and prawn. Further, a remarkable concentration-controlled diverse emission with a red shift difference of 141 nm is detected with 1,3-diaminopropane (1,3-DAP) vapor (from 29 to 319 mg/L) for the first time. Thus, a cost-effective device is developed to detect 1,3-DAP at a precise concentration, visible through the naked eye

Robotic Bronchoscopy: A Comprehensive Review

Lung cancer, a major global cause of cancer-related deaths, demands continual advancements in diagnostic methodologies. This review delves into the transformative role of Robotic-Assisted Bronchoscopy (RAB) in redefining lung cancer diagnostics. As lung cancer screenings intensify, leading to a surge in pulmonary nodule diagnoses, navigational bronchoscopy, notably electromagnetic navigational bronchoscopy (ENB), faces persistent limitations. Examining key RAB platforms—Monarch™, Ion™ and the Galaxy System™—reveals their distinctive features, with RAB demonstrating superior diagnostic yields over traditional biopsy methods. However, challenges include CT-to-body divergence (CBCT) and divergent findings in diagnostic yield studies and a lack of head-to-head comparisons with non-RAB modalities. Future directions should explore RAB’s potential therapeutic applications, shaping the landscape of both diagnostics and therapeutics in lung cancer management

Isomeric Benzenediol-Linked Organophosphonates as a Handy Reusable Emitting Platform: Diversity in Polyamine Vapor Detection

This work introduces metal/column-free facile quantitative access to conformationally twisted catechol-linked organophosphonate (CAP) as a blue-emitting solid that could reversibly detect only 1,3-diaminopropane (DAP) and 1,2-ethylenediamine (EDA) vapors, belonging to industrially and pharmaceutically abundant crucial diamines. In CAP, two adjacent hydroxy groups in a benzene ring facilitate selective diamine–dihydroxy (amine–phenol type) interactions in the solid phase, leading to a quenched emission with selectively smaller aliphatic PAs, that is, DAP and EDA. The disparity was noticed with an isomeric resorcinol-linked emitter (RAP), detecting various polyamine vapors with superior sensitivity. A one-carbon-away placed hydroxy group in RAP can only generate a monoamine–hydroxy complex, not diamine–dihydroxy. The more acidic nature of resorcinol would prefer ionizing the amines and, consequently, creating amine/hydroxy interactions. More systematic investigations reveal an exciting role of amine–hydroxy realization for the catechol analog in the solid phase with a syn–anti conformation for CAP. Unlike CAP, RAP’s available crystal void space creates considerable room in which to come closer and facilitates amine–phenol interactions. The role of phosphonates in the selective detection of PAs is also examined. Observed outcomes are substantiated by FT-IR, single-crystal X-ray diffraction, SEM, XPS, and mass spectroscopic studies. The proposed amine–hydroxy interactions are further supported by DFT-optimized molecular structures
