Boosting Electrocatalytic NO Reduction via Intermediate Adsorption Modulation on Synergistic CuCo Bimetallic Oxide Catalysts.

Cobalt-based catalysts are extensively employed in the electrocatalytic nitric oxide reduction reaction (NORR) for ammonia synthesis due to their superior ammonia selectivity. However, their practical implementation is significantly hindered by insufficient adsorption capacity toward NO and critical intermediates. To address this limitation, we strategically integrated copper (Cu) into a cobalt (Co) matrix through hydrothermal synthesis followed by controlled annealing, resulting in a well-dispersed CuCo bimetallic catalyst (CuCoO-650).

Transforming the management of radiotherapy-induced hypothyroidism in nasopharyngeal carcinoma through an Innovative individualized radiation dosage model: A multicenter retrospective analysis.

Purpose: Current guidelines for thyroid radiation dose prescription lack uniformity and fail to consider the unique characteristics of individual patients. This study aimed to develop an individualized thyroid dosing regimen to enhance thyroid protection during radiotherapy.

Methods And Materials: In this study, we enrolled 621 patients with nasopharyngeal carcinoma (NPC) across four distinct cancer centers, stratifying the data into a training cohort and two external validation cohorts.

Treatment outcomes in nasopharyngeal carcinoma patients with parotid lymph node metastasis: An 11-year experience at a tertiary cancer center.

Parotid lymph node (PLN) metastasis in nasopharyngeal carcinoma (NPC) is rare, with limited data guiding its management and prognosis. We retrospectively analyzed 6924 non-metastatic NPC patients at our tertiary cancer center, identifying 126 patients with PLN metastasis confirmed by fine-needle aspiration cytology (FNAC) and magnetic resonance imaging (MRI). Survival outcomes and prognostic factors were assessed using Kaplan-Meier estimates, log-rank tests, propensity score matching (PSM), and Cox regression.

Enhancing diagnostic accuracy and timeliness in NPC is crucial for clinical implications. Radiomics has demonstrated significant potential in the clinical management of NPC.

Utilization of 18F-FDG Standardized Uptake Value and Metabolic Tumor Volume to Predict Local Failure in Nasopharyngeal Carcinoma.

Introduction: The aim was to evaluate the prognostic values of pretreatment 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) parameters for predicting local failure in nasopharyngeal carcinoma (NPC) patients in the intensity-modulated radiotherapy (IMRT) era.

Methods: Retrospective analysis was performed on 759 patients with NPC who underwent pretreatment 18F-FDG PET. The optimal cutoff values for maximum standardized uptake value (SUVmax) and metabolic tumor volume (MTV) were determined by receiver operating characteristic curve analysis.

Reduced graphene oxide membrane with small nanosheets for efficient and ultrafast removal of both microplastics and small molecules.

The clogging of sieving pores due to the complex sewage system of mixed molecules and nanoparticles of different scales is a difficulty in the membrane-based separation process. When the holes are reduced to the point where they can repel small molecules in the contaminants, large-molecule contaminants can adsorb to the holes and decrease the permeability. A similar question remains in new promising graphene oxide (GO) membranes.

Electrochemical Synthesis of Metasequoia-Like Reduced Graphene Oxide Coated Cobalt-Silver Catalyst for Stable and Efficient Electrocatalytic Nitrate Reduction to Ammonia.

Electrocatalytic nitrate (NO ) reduction to ammonia (NH) is a green and efficient NH synthesis technology. Metallic silver (Ag) is one of the well-known electrocatalysts for NO reduction. However, under alkaline conditions, its poor water-splitting ability fails to provide sufficient protonic hydrogen required for NH synthesis, resulting in low NH selectivity.

A GO regulated bimetallic CoFe catalyst for efficient electrochemical nitrate reduction to ammonia under acidic conditions.

Electrocatalytic nitrate reduction to ammonia (ENRA) in acidic media is currently a challenge. Herein, we presented a CoFeO/GO catalyst that exhibited a high faradaic efficiency (95.51%) and ammonia yield rate (1268.

Effects of Central Metal Ion on Binuclear Metal Phthalocyanine-Based Redox Mediator for Lithium Carbonate Decomposition.

LiCO is the most tenacious parasitic solid-state product in lithium-air batteries (LABs). Developing suitable redox mediators (RMs) is an efficient way to address the LiCO issue, but only a few RMs have been investigated to date, and their mechanism of action also remains elusive. Herein, we investigate the effects of the central metal ion in binuclear metal phthalocyanines on the catalysis of LiCO decomposition, namely binuclear cobalt phthalocyanine (bi-CoPc) and binuclear cobalt manganese phthalocyanine (bi-CoMnPc).

Significance of saline nasalirrigation for COVID-19 infection: observations and reflections from nursing care of nasopharyngeal carcinoma.

Background: Coronavirus disease 2019 (COVID-19) has placed a tremendous burden on the world's healthcare systems, prompting medical professionals worldwide to diligently research and experiment with treatment methods to prevent infection and alleviate symptoms. Previous studies have shown the potential of nasal irrigation in reducing viral clearance time and alleviating local symptoms of COVID-19. However, views differ regarding its efficacy in improving systemic symptoms.

Significance of chemotherapy for older patients with nasopharyngeal carcinoma in the intensity-modulated radiotherapy era: A propensity score matching analysis.

Introduction: This study aimed to evaluate the survival and prognosis of older patients with nasopharyngeal carcinoma (NPC) who received intensity-modulated radiotherapy (IMRT) alone versus IMRT plus chemotherapy using propensity score matching (PSM).

Materials And Methods: We enrolled 841 older patients with NPC aged 60 years and above without metastasis receiving IMRT alone or chemoradiotherapy from 2012 to 2019. The comorbidity was assessed by adult comorbidity evaluation (ACE-27).

Methane Activation by [AlFeO ] : the Hidden Spin Selectivity.

The performance of heteronuclear cluster [AlFeO ] in activating methane has been explored by a combination of high-level quantum chemical calculations with gas-phase experiments. At room temperature, [AlFeO ] is a mixture of [AlFeO ] and [AlFeO ] , in which two states lead to different reactivity and chemoselectivity for methane activation. While hydrogen extracted from methane is the only product channel for the [AlFeO ] /CH couple, [AlFeO ] is able to convert this substrate to formaldehyde.

How Doping Affects the Activity of the Aluminum Oxide Support.

The performance of heteronuclear clusters [AlXO ] (X=Al, AlO , AlMg O , AlZnO, AlAu , Mg, Y, VO, NbO, TaO) in activating methane has been explored by a combination of high-level quantum calculations with reported and supplementary gas-phase experiments. With different dopants in [AlXO ] , the mechanism, reactivity and selectivity towards methane activation varies accordingly. The classic HAT competes with PCET, depending on the composition of intramolecular interactions.

On the origin of reactivity variation upon sequential ligation: the [Re(Cl)]/CH ( = 1-3) couples.

The potential of [ReCl] ( = 1-3) in activating methane has been explored by using a combination of gas-phase experiments and high-level quantum calculations. When the number of Cl ligands increases, the reactivity towards methane activation varies accordingly. While [ReCl] ( = 1-2) are able to dehydrogenate methane by a three-state reactivity scenario, [ReCl] shows inertness towards methane at ambient conditions.

Reversed Active Sites Boost the Intrinsic Activity of Graphene-like Cobalt Selenide for Hydrogen Evolution.

Optimizing the hydrogen adsorption Gibbs free energy (ΔG ) of active sites is essential to improve the overpotential of the electrocatalytic hydrogen evolution reaction (HER). We doped graphene-like Co Se with sulfur and found that the active sites are reversed (from cationic Co sites to anionic S sites), which contributed to an enhancement in electrocatalytic HER performance. The optimal S-doped Co Se composite has an overpotential of 108 mV (at 10 mA cm ) and a Tafel slope of 59 mV dec , which exceeds other reported Co Se-based electrocatalysts.

NiSe/CdS composite nanoflakes photocatalyst with enhanced activity under visible light.

Degrading organic pollutants using a photocatalyst under visible light is one of the effective ways to solve the increasingly serious environmental pollution problem.
