Performance evaluation of phosphonium based deep eutectic solvents coated cerium oxide nanoparticles for CO capture.

The critical challenge being faced by our current modern society on a global scale is to reduce the surging effects of climate change and global warming, being caused by anthropogenic emissions of CO in the environment. Present study reports the surface driven adsorption potential of deep eutectic solvents (DESs) surface functionalized cerium oxide nanoparticles (CeNPs) for low pressure CO separation. The phosphonium based DESs were prepared using tetra butyl phosphoniumbromide as hydrogen bond acceptor (HBA) and 6 acids as hydrogen bond donors (HBDs).

The Evaluation of Inflammatory Biomarkers in Predicting Progression of Acute Pancreatitis to Pancreatic Necrosis: A Diagnostic Test Accuracy Review.

Acute pancreatitis is the acute inflammation of the pancreas; 30% of cases may progress to pancreatic necrosis. The aim of this study was to assess the diagnostic accuracy of inflammatory biomarkers (C-reactive protein (CRP), procalcitonin (PCT), and lactate dehydrogenase (LDH)) in detecting pancreatic necrosis in adults with confirmed acute pancreatitis within 14 days of symptom onset and without organ failure. A systematic search was conducted across the Cumulative Index of Nursing and Allied Health (CINAHL), Cochrane, Embase, PubMed, and Web of Science until May 30, 2022, with the following keywords: acute disease, biomarkers, C-reactive protein, calcitonin, differential, diagnosis, lactate dehydrogenase, pancreatitis, acute necrotizing, necrosis, sensitivity, specificity.

Knowledge, attitude, and behaviour of dentists working during the COVID-19 pandemic: A cross-sectional survey.

Background: The coronavirus disease 2019 (COVID-19) has immensely affected the world's population at physical and psychosocial levels. Dentists are no different from other healthcare providers, as they are equally if not more exposed to the threat of getting infected.

Objective: To assess the experience and behavior of public and private sector dentists practicing during the COVID-19 pandemic and their knowledge about it.

Template-based textural modifications of polymeric graphitic carbon nitrides towards waste water treatment.

The composite materials based on graphitic carbon nitrides (g-CN) are remarkably better semiconductors, but the inherent photocatalytic performance in its generic synthesis form is not up to the mark. Eminence efforts have been made to improve its performance and photocatalytic efficiencies. Recently, extensive investigations have been performed to develop their texturally modified and highly porous structures to get around the big flaws of bulk g-CN.

Cyclic oxygen exchange capacity of Ce-doped VO materials for syngas production high-temperature thermochemical-looping reforming of methane.

Synthesis gas production solar thermochemical reduction-oxidation reactions is a promising pathway towards sustainable carbon-neutral fuels. The redox capability of oxygen carriers with considerable thermal and chemical stability is highly desirable. In this study, we report Ce-doped VO structures for high-temperature thermochemical-looping reforming of methane coupled to HO and CO splitting reactions.

What Makes People Hide Knowledge? Influence of Passive Leadership and Creative Self-Efficacy.

Although numerous studies have been conducted in the field of knowledge sharing with a focus given to its importance, very little attention has been given to knowledge hiding practices. A very few studies have been found to make an attempt to figure out its impact and antecedents. Likewise, the negative role of passive leadership in the project management literature has not been evidenced enough despite its existence in project-based organizations.

Development and Comparative Analysis of Electrochemically Etched Tungsten Tips for Quartz Tuning Fork Sensor.

Quartz Tuning Fork (QTF) based sensors are used for Scanning Probe Microscopes (SPM), in particular for near-field scanning optical microscopy. Highly sharp Tungsten (W) tips with larger cone angles and less tip diameter are critical for SPM instead of platinum and iridium (Pt/Ir) tips due to their high-quality factor, conductivity, mechanical stability, durability and production at low cost. Tungsten is chosen for its ease of electrochemical etching, yielding high-aspect ratio, sharp tips with tens of nanometer end diameters, while using simple etching circuits and basic electrolyte chemistry.

Concentration-Dependent Solar Thermochemical CO/HO Splitting Performance by Vanadia-Ceria Multiphase Metal Oxide Systems.

The effects of V and Ce concentrations (each varying in the 0-100% range) in vanadia-ceria multiphase systems are investigated for synthesis gas production thermochemical redox cycles of CO and HO splitting coupled to methane partial oxidation reactions. The oxidation of prepared oxygen carriers is performed by separate and sequential CO and HO splitting reactions. Structural and chemical analyses of the mixed-metal oxides revealed important information about the Ce and V interactions affecting their crystal phases and redox characteristics.

Fractionation of Lignocellulosic Biomass over Core-Shell Ni@Al O Catalysts with Formic Acid as a Cocatalyst and Hydrogen Source.

Highly dispersed, core-shell Ni@Al O on activated carbon (AC) catalysts were prepared to develop an effective, external-hydrogen-free fractionation process for various types of lignocellulosic biomass. In a mixture of formic acid, ethanol, and water at 190 °C, the conversion of oak wood produced 23.4 C% lignin-derived phenolic monomers (LDPMs) and highly delignified pulp-rich solid.

Enhanced mechanical, thermal and antimicrobial properties of poly(vinyl alcohol)/graphene oxide/starch/silver nanocomposites films.

In the present work, synthesis of poly(vinyl alcohol)/graphene oxide/starch/silver (PVA/GO/Starch/Ag) nanocomposites films is reported. Such films have been characterized and investigated for their mechanical, thermal and antimicrobial properties. The exfoliation of GO in the PVA matrix occurs owing to the non-covalent interactions of the polymer chains of PVA and hydrophilic surface of the GO layers.

Liquid crystals based sensing platform-technological aspects.

In bulk phase, liquid crystalline molecules are organized due to non-covalent interactions and due to delicate nature of the present forces; this organization can easily be disrupted by any small external stimuli. This delicate nature of force balance in liquid crystals organization forms the basis of Liquid-crystals based sensing scheme which has been exploited by many researchers for the optical visualization and sensing of many biological interactions as well as detection of number of analytes. In this review, we present not only an overview of the state of the art in liquid crystals based sensing scheme but also highlight its limitations.

From Eye Drops to ICU, a Case Report of Three Side Effects of Ophthalmic Timolol Maleate in the Same Patient.

Timolol Maleate (also called Timolol) is a nonselective beta-adrenergic blocker and a class II antiarrhythmic drug, which is used to treat intraocular hypertension. It has been reported to cause systemic side effects especially in elderly patients with other comorbidities. These side effects are due to systemic absorption of the drug and it is known that Timolol is measurable in the serum following ophthalmic use.
