The ongoing discharge of hazardous dyes from industrial processes has intensified global water pollution, posing serious threats to aquatic ecosystems and human health. Addressing this challenge, our study explores the potential of bio-based carbon nanomaterials (CNM), synthesized from onion peel biowaste and designated as ON11, as effective agents in dye removal. These CNMs were incorporated into a mixed matrix membrane (MMM), using polysulfone (PSU) as the membrane substrate, to enhance dye adsorption.

Protonic ceramic fuel cells (PCFCs) should exhibit high performance at intermediate temperatures in the range of 400-600 °C. To reduce the operating temperature, more active air electrodes (positrodes) are needed. In the present work, BaCoFeMgYO (BCFMY) is investigated as a positrode material for application in PCFCs as well as solid oxide fuel cells (SOFCs).

Objectives: Examining cytokine profile complexities in chronic autoimmune disorders holds significant clinical importance. In order to address the similarities and differences related to SLE and RA, it was necessary to evaluate their cytokine chemokine profiles. Such analyses would give pointers towards differences, leading thereby to explore the potential of cytokines/chemokines as biomarkers.

Considering the multifactorial and complex nature of Alzheimer's disease and the requirement of an optimum multifunctional anti-Alzheimer's agent, a series of triazole tethered coumarin-eugenol hybrid molecules was designed as potential multifunctional anti-Alzheimer's agents using donepezil and a template. The designed hybrid molecules were synthesized a click chemistry approach and preliminarily screened for cholinesterase and Aβ aggregation inhibition. Among them, AS15 emerged as a selective inhibitor of AChE (IC = 0.

Energy hubs, with their diverse regeneration and storage sources, can engage concurrently in energy transfer and storage. It is anticipated that managing the energy of these hubs within energy networks could enhance economic, environmental, and technical metrics. This article explains how electrical and thermal network hubs manage their energy consumption in the context of the multi-criteria objectives of efficiency, sustainability, reliability of the network operator, and operation.

Article Synopsis
  • - Intercalation reactions depend on how the electronic and structural properties of host (like TaS) and guest materials (like divalent ions) interact, making it harder for divalent ions like Mg to intercalate compared to monovalent ions.
  • - This study explores the cointercalation of Mg and hydrogen (H) into TaS to produce bulk polycrystalline MgHTaS, where hydrogen can be removed by heating at around 400 °C without changing the crystal structure.
  • - The research also investigates how the superconducting properties relate to electronic carrier density using both theoretical calculations and experiments, highlighting the benefits of using hydrides for intercalation reactions.

Purpose: Radiotherapy is frequently employed for palliative treatment in locally advanced head and neck squamous cell carcinoma (HNSCC) but radiation dose fractionation regimens are not well-defined. We designed this phase 3 randomized controlled trial to compare two weekly hypo fractionated regimes and study the effect on progression-free survival (PFS) in this subset of patients.

Materials And Methods: Non-metastatic locally advanced HNSCC patients (n = 305) who were not suitable for curative treatment were randomized to Arm A (20 Gy/5#/5 days) and Arm B (30 Gy/5#/5 days).

Background: The ACR in 2021 and the EULAR in 2022 published recommendations for management of ANCA-associated vasculitis. Given the differences in the demographic, clinical profiles, and the socio-economic realities between various countries, there is a need for development of guidelines for the management of AAV for less economically developed regions of the world.

Methods: These guidelines were made following the GRADE methodology.

Ultrasensitive thermal lens (TL) spectroscopy, where the interplay between conduction and convection is crucial, provides profound insights into molecular behavior. This work focuses on the critical role of molecular convection by using the dual-beam z-scan method and time-resolved TL spectroscopy. We specifically investigated the correlation between the detection iris and the spot size of the pump beam.

Collisions of the transcription and replication machineries on the same DNA strand can pose a significant threat to genomic stability. These collisions occur in part due to the formation of RNA-DNA hybrids termed R-loops, in which a newly transcribed RNA molecule hybridizes with the DNA template strand. This study investigated the role of RAD52, a known DNA repair factor, in preventing collisions by directing R-loop formation and resolution.

Quantum spin liquids (QSLs) have become a key area of research in magnetism due to their remarkable properties, such as long-range entanglement, fractional excitations, and topologically protected phenomena. Recently, the search for QSLs has expanded into the three-dimensional world, despite the suppression of quantum fluctuations due to high dimensionality. A new candidate material, KNi(SO), belongs to the langbeinite family and consists of two interconnected trillium lattices.
