Atomic layer deposition of ZnO gas diffusion electrodes for tunable CO2 electroreduction in membrane electrode assemblies

Manpatilan, Lovelle Rhoy · Porro, Samuele · Castellino, Micaela · Allione, Marco · y 5 más

The electrochemical conversion of CO2 to CO in membrane electrode assembly (MEA) electrolyzers using gas diffusion electrodes (GDEs) offers a sustainable and scalable pathway for carbon utilization. Here, we present a one-step atomic layer deposition (ALD) approach to prepare ZnO-based GDEs with tunable loadings and hi...

LM-PCVMNet: Pediatric cervical vertebral maturation analysis with deep fusion of landmarks and metadata

Peng Wang · Wanzhen Song · Anli Wang · Xueshuo Xie · y 2 más

Cervical vertebral maturation (CVM) assessment plays a pivotal role in orthodontic diagnosis and determining the optimal timing of treatment, especially for pediatric patients. In this paper, we propose LM-PCVMNet, a novel deep learning framework for automatic pediatric CVM staging. Specifically, our method integrates...

Direct monitoring of pesticide residues by DART-MS: From river water to fish scales

Almir Custodio · Nathália dos Santos Conceição · João Victor Borges Assis · Simone Nascimento · y 3 más

This study demonstrates the feasibility of direct analysis in real-time mass spectrometry (DART-MS) for rapid pesticide residues screening in aquatic ecosystems, highlighting the application of fish scales as a non-lethal biological matrix. For this purpose, multivariate approaches were employed to optimize the signifi...

Laboratory-to-pilot evaluation of CO2 absorption by aqueous KOH in packed columns

Meng Shi · Randi Neerup · Sai H.B. Vinjarapu · Sara Vallejo Castaño · y 5 más

Electrochemical regeneration techniques have renewed interest in aqueous potassium hydroxide (KOH) solution as a potential absorbent for post-combustion CO2 capture. However, absorber performance at different scales and its sensitivity to the loading of the regenerated solvent remain underexplored, primarily due to the...

Molten KCl-thiourea synergy enabled N/S Co-doped lignin carbon for boosted CO2 adsorption and supercapacitors

Tong Zhou · Yan Zhang · Mingxing Zhou · Hao Zhang · y 9 más

Lignin holds great promise for fabricating multifunctional carbon materials, yet it is hindered by the difficulty of simultaneous pore structure regulation and heteroatom doping. To address this challenge, we propose a novel molten KCl-thiourea synergistic strategy for the scalable synthesis of N/S co-doped lignin-deri...

Exploring strategies to confine magneto-immunoassays enzymatic products on gold interdigitated microelectrodes (G-IDE) for enhanced sensitivity: application to detection of respiratory syncytial virus (RSV)

Xana García-Fernández · Judit Prat-Trunas · Narcís Saubi · Manuel Gutiérrez-Capitán · y 5 más

Magnetic particles (MP) combined with screen-printed electrodes (SPE) are widely used for enzyme-labelled magneto-immunoassays enabling quantitative electrochemical detection of analytes. In contrast, thin-film electrodes are less frequently implemented, despite their reported high sensitivity. This study aims to ident...

Parasitic castration and its physiological consequences: Insights from parasitism of the carrot weevil (Listronotus oregonensis) by the nematode Bradynema listronoti

Alissandre, Lavoie · Jacques, Brodeur · Hassan, Sabik · Fleur, Gagnon · y 1 más

Parasitic castration represents a strategy by which parasites suppress host reproduction by consuming gonads, disrupting the endocrine system, or indirectly manipulating host resource allocation. The nematode Bradynema listronoti Zeng parasitizes both sexes of the carrot weevil, Listronotus oregonensis (LeConte), but i...

An improved bound on the number of dot products determined by a finite point set in the plane

Michalis Kokkinos

We are interested to bound from below the number of distinct dot products determined by a finite set of points $P$ in the Euclidean plane. In this paper, we build on the work of B. Hanson, O. Roche-Newton, and S. Senger, to obtain the improved lower bound \[|\{p\cdot q : p,q\in P\}|\gtrsim |P|^{\frac2 3 + \frac{7}{1425...

On subgroup perfect codes in vertex-transitive graphs

Binzhou Xia · Junyang Zhang · Zhishuo Zhang

A subset $C$ of the vertex set $V$ of a graph $Γ$ is called a perfect code in $Γ$ if every vertex in $V\setminus C$ is adjacent to exactly one vertex in $C$. Given a group $G$ and a subgroup $H$ of $G$, a subgroup $A$ of $G$ containing $H$ is called a perfect code of the pair $(G,H)$ if there exists a coset graph $\mat...

A compositional kernel model for feature learning

Feng Ruan · Keli Liu · Michael Jordan

We study a compositional variant of kernel ridge regression in which the predictor is applied to a coordinate-wise reweighting of the inputs. Formulated as a variational problem, this model provides a tractable setting for studying feature learning in compositional architectures. From the perspective of variable select...
