Hybridization of Carbon Nanotube Tissue, MnO2 Catalyst and CFx as an Advanced Air Cathode in Metal–Air Batteries
Authors: Levy Natasha Ronith , Ein-Eli Yair 
Published: September 2023

We first present the utilization of hybrid carbon nano-tube (CNT) – manganese dioxide (MnO2) tissues as air electrodes in nonaqueous aluminum- and lithium-based battery systems. The CNT tissues are impregnated with α-manganese dioxide nanoparticles via a straightforward binder-free ultrasonic treatment, thereby enabling an improved oxygen reduction reaction (ORR) catalytic activity. Half-cell potentiodynamic measurements along with full-cell discharge evaluations of Li- and Al-based battery systems are reported. Higher discharge potentials and capacities were obtained from generic and advanced hybrid CNT–MnO2 air cathodes. The discharge products obtained on the air cathode surface were studied using high-resolution scanning electron microscopy. Their chemical compositions were evaluated using elemental mapping energy-dispersive X-ray spectroscopy. The stability of the α-MnO2 catalyst was studied using X-ray photoelectron spectroscopy and electron paramagnetic resonance spectroscopy, thereby indicating the ongoing formation of an outer MnF2 shell layer, which affected the α-MnO2 functionality, as an efficient ORR catalyst. We conclude this part of the talk by showing that the function of the metal–air battery is enabled by using porous carbon nanotube (CNT)-based tissue substrates loaded with MnO2 catalyst.
In contrast, fluorinated graphite (CFx) coating on the CNT substrate provides an additional discharge process, enhancing discharge capacity. Two CFx loadings are investigated, and their performances are compared with that of a pristine CNT tissue. Electrochemical evaluations, including half- and full-cell measurements, are performed to examine the effect of the coating layer thickness on the ability of the cell to function at high discharge rates.

Published: September 2023

Reduced graphene oxide (rGO) has attracted significant attention as an active electrode material for sensors and flexible energy devices due to its high electric conductivity and large surface area. rGO is usually obtained from graphene oxide(GO) through a thermal, chemical, photochemical, and electrochemical reduction process. Compared to the other reduction strategy, laser reduction is a single-step, precise, low cost, and chemical-free processing that can be directly applied on the GO membrane at room temperature in an ambient condition.The laser irradiation parameter, such as laser source, power, speed, and frequency, plays an important role in reduction optimization. In general, the quality of the rGO is not as high as that of pristine graphene because of incomplete reduction, and oxygenated defects involved in the reduction process.The not fully removed oxygenated function group not only influence the sensitivity and selectivity of the electrode, but also influences response time and recovery time during sensing and the electrochemical window of the supercapacitor made with those rGO electrode.
This study aims to develop reduced graphene oxide (rGO) through laser irradiation for application in supercapacitors and electrochemical sensors as electrodes. GO membranes were fabricated with a layer-by-layer assembly process first then further reduced through conventional CO2 laser reduction. The laser irradiation parameters including intensity, frequency, and scan speed will be optimized to achieve the reduction up to maximi, C/O ratio. The effects of the reduction will be characterized and evaluated using scanning electron microscope (SEM), Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, X-ray diffraction (XRD)spectroscopy, and four-point probe station. The influence of the humidity on the impedance of the rGO electrode and the capacitance of the planar supercapacitor made with rGO electrode will also be analyzed for potential application of as-prepared rGO electrodes in supercapacitors and humidity sensors.
Porosity Engineering of Si Nanoparticle-Based Electrodes by Carbon Nanostructures
Authors: Kim Jae Ho , Pach Gregory F. , Carroll Gerard (MIke) Michael , Neale Nathan R. 
Published: September 2023

Silicon (Si) has been considered as a next-generation anode material due to natural abundance, low operating potential (<0.5 V vs. Li/Li+), and high theoretical specific capacity of 4200 mAh g-1.1 However, the electrochemical alloying reaction of Si involves large volume changes of 400% during lithiation and delithiation, causing cracking and pulverization of Si.1 In addition, solid electrolyte interface (SEI) of Si anode experiences constant changes due to unstable SEI reactivity.2 Considerable efforts have been made to design nanostructured Si materials to address the issues because nanostructuring can relieve the mechanical strain.3 However, when compared to micrometer-sized active materials having sufficient electrolyte pathway through interparticle space, the nanoparticle (NP)-based electrodes tend to be densely packed. As mass loading is higher and electrode is thicker, ion transport issue can become more severe in the densely packed electrodes.4

In this work, we will present studies on engineered porosity impacts performance in Si NP electrodes by altering porosity with carbon nanostructures. We explore the extreme limit of effectively non-porous electrodes using quasi-spherical, 6 nm diameter Si NPs produced via plasma-enhanced chemical vapor deposition (PECVD), which result in densely packed electrodes when slurry is prepared with conventional carbon black. We engineer porosity using carbon nanostructures including single-walled carbon nanotubes and carbon nanorods in place of conventional carbon black to create pore structure in Si NP-based electrodes. These experiments provide a correlation between mass loading, porosity and silicon utilization in Si NP-based electrodes.

(Invited) Near Infrared Fluorescence Lifetime Imaging of Biomolecules with Carbon Nanotubes
Authors: Kruss Sebastian 
Published: September 2023

Single wall carbon nanotubes (SWCNTs) are versatile building blocks for biosensors. Their near infrared (NIR) fluorescence enables detection of biomolecules in the optical tissue transparency window. Their surface chemistry can be tailored to selectively interact with analytes, which typically changes the fluorescence intensity. However, such signals are affected by external factors such as sample movement or fluctuations in excitation light. Here, we demonstrate fluorescence lifetime imaging microscopy (FLIM) of SWCNT-based sensors in the NIR as absolute and calibration-free method.
For this purpose, we use a tailored laser scanning confocal microscope (LSCM) optimized for NIR signals (>800 nm) and time correlated single photon counting (TCSPC). (GT)10-DNA modified SWCNTs serve as sensor of the important neurotransmitter dopamine. The detected fluorescence signal > 900 nm increases in lifetime up to 25 %. These lifetime sensors are used as paint to cover cells and report extracellular dopamine in 3D. We therefore show the potential of using fluorescence lifetime in combination with confocal microscopy as readout for SWCNT-based sensors.
Characterizing the Non-Covalent Binding of a Pyrene-Derived Linker for DNA Immobilization on Graphene Field-Effect Transistors

Published: September 2023

Graphene field-effect transistors (G-FETs) constitute an emerging platform for biosensing applications. Most genomic applications with G-FETs use single-stranded DNA (ssDNA) as probes in order to capture a specific target DNA sequence and to detect the corresponding change in the electrical response of the sensor1. Controlling the distribution of DNA probes on the graphene surface is crucial to the sensitivity, selectivity and reproducibility of the sensors1. The most popular immobilization approach uses a non-covalent linker molecule named 1-pyrenebutanoic acid succinimidyl ester (PBASE)1. This bifunctional molecule binds to the graphene surface through non-covalent π-π interactions via its aromatic pyrene group, and on the other end, its succinimidyl ester group can form a covalent bond with amine groups added to the terminal end of ssDNA probes. However, the adsorption process of PBASE molecules is not well controlled, which represents a limitation in the optimization of G-FET biosensors.
Here, we present an investigation of the kinetics of the non-covalent adsorption of PBASE on graphene, in order to control the density of ssDNA probes for biosensing applications with G-FETs. We fabricated G-FET sensor arrays using CVD-grown graphene and photolithography techniques, as described previously2. First, we investigated the effect of incubation time on PBASE coverage on graphene, using electrical curves as well as Raman hyperspectral imaging (RIMA). We report a significative and reproducible electrical signature for the PBASE compared to the control without PBASE. We find that this electrical signature appears and saturates quickly compared to the timescales usually reported in the literature. Corroborating results were obtained with RIMA spectroscopy, showing a rapid response of the graphene modes following PBASE incubation. Next, we studied the effect of PBASE accumulation on the assembly of ssDNA probes. We will discuss the combined effect of PBASE accumulation and screening effects in saline buffer on the electrical signature of ssDNA probes. Our results will enable a better control on the non-covalent functionalization of graphene with PBASE for the assembly of various biomolecular probes for biosensing applications.

Published: September 2023

In this report, we present the 3D graphene foams developed by chemical vapour deposition technique, acetone as a carbon source, and Ni as scaffolds. Graphene is a 2D material with diverse applications. However, there are essential applications in gas and liquid media that can benefit from the unique properties of graphene but require a 3D structure able to interact thoroughly with the medium. We studied how the structural properties of the 3D graphene foams depend on the growth parameters, such as temperature, precursor concentration, and Ni foams thickness. This material will be used as an electrode in sensing some enzymes or other biological molecules
The systematic and reproducible fabrication of 3D graphene would enable further applications for research and industrial processes, such as catalysis and environmental remediation. The detailed analysis will be discussed during the meeting presentation.
(Invited) Demonstration of ATPS Phase Separation, B-Field Concentration and Manipulation of Sars-Cov-2 Viral Particles
Authors: Ignatova Tetyana , Rotkin Slava V. 
Published: September 2023

A technology, based on fluorescence sensing in a liquid sample and capable for an early detection of a pathogen at extremely low concentration, is very desirable though equally challenging to develop. In optical sensors, a typical fluorescent signal would be too weak to measure without special tools, unless the detected analyte, tagged with a fluorescent label, can be separated and concentrated.
In this work a new combined technology[1] will be presented. An assembly of a monoclonal antibody (mAb) functionalized with a fluorescent tag with the S-proteins at the surface of inactivated coronavirus is achieved. In order to separate a bound fluorescent tag (signal) and free tag molecules (background), we simultaneously attach to the virus surface ferrite magnetic nanoparticles (mNP) functionalized with the mAb (without fluorescent tag). Since the surface of the SARS-CoV2 virus has a large number of binding sites, a "sandwich" assembly of mNP-mAb:virus:mAb-FL happens. At the same time, non-specific binding of the fluorescent tag to mNPs is excluded. As a result, the fluorescent tag bound to the analyte can be manipulated by magnetic force and moved with respect to (unused) free tag molecules.
Fig.1 shows the fluorescence signal of the mNP-mAb:virus:mAb-FL sandwich assemblies, that were first concentrated by an aqueous two-phase system separation (ATPS)[2] – carefully designed mix of PEG/dextran solutions. Upon dividing the ATPS into PEG bulk phase and dextran bubbles, the viral assemblies (and free non-bound tag) were separated into the PEG phase. Applying vertical magnetic field as shown in the figure resulted in additional significant concentration of the assemblies against the wall of a dextran bubble. Thus, we achieved a clear separation of the virus (as detected by direct fluorescence signal) with respect to the free tag molecules (background) residing in the bulk solution.

Published: September 2023

Viral and microbiological infections are a major cause of death that burdens the infrastructure of health systems. To contain the spread of pathogens and assess available treatment options, a number of diagnostic methods have been developed. However, the development of diagnostic tests is typically time consuming and, in the light of current pandemics, the need for adaptable concepts has become more apparent.
For sensor applications that require a minimally invasive read out, optical systems offer a rapid detection of biomolecules with a high spatial and temporal resolution. Due to the reduced autofluorescence, absorption and scattering, the near-infrared (NIR, 870 – 2400 nm) tissue transparency window offers an improved signal-to-noise ratio. Biosensors that fluoresce in this region are therefore highly desirable for biological applications and single-walled carbon nanotubes (SWCNTs) have emerged as versatile NIR fluorescent building blocks in this context. Here, we report a biofunctionalization strategy for single walled carbon nanotube (SWCNT) based (bio-)sensors that uses a generic signal transduction mechanism for different recognition elements. It allows the detection of viral compounds in subnanomolar concentrations, which can be used to fingerprint them at 1020 nm in the near infrared. In summary, we present a concept that allows rapid exchange of recognition units and a straightforward method to detect pathogens.

Abstract
In this contribution the author will proceed in three steps. First, he will raise questions about the various rhetorical approaches one might follow in order to study the argumentative development of Galatians, considering the different methodological options. Second, he will offer a survey of existing rhetorical research on Galatians. Then he will seek to outline the argumentative structure and development of Galatians, in order to understand what is really at stake in this Pauline letter. At the end it will be proven that the literary rhetorical approach in studying Galatians is highly useful for a deep understanding of the text of the letter and its aim: Paul wants to re-evangelise the addressees.
Les démons étaient-ils vraiment le problème à Corinthe ?
Authors: Patmore Hector M. 
Published: September 2023

Abstract
A consensus of opinion exists among scholars that Paul appears to contradict himself in 1 Cor 10:17–22: on the one hand, he makes clear that idols have no existence beyond the material objects themselves ; on the other hand, he appears to warn the Corinthians that they are exposing themselves to a dangerous metaphysical reality, namely demons (i.e., evil supernatural beings), by taking part in pagan cults. This supposed non sequitur is generally resolved by claiming that Paul adheres to two Jewish traditions simultaneously. The Jewish witnesses, however, do not support such a conclusion. In fact, the Jewish sources offer an alternative solution to this supposed problem, namely that Paul uses the word δαιμόνια to designate foreign gods to which he attributes no metaphysical reality. In short, there are no demons involved. As such, he maintains a biblical position : even if the idols are nothing but wood and stone, idolatry is forbidden.
Inulin has a beneficial effect by modulating the intestinal microbiome in a BALB/c mouse model
Authors: Zhu Z. , Hu C. , Liu Y. , Wang F. , Zhu B. 
Published: September 2023

Abstract
Food allergy is an important health problem that affects human quality of life and socioeconomic development, and its treatment requires improvement. Intestinal flora dysbiosis is closely associated with food allergies. A sensitised mouse model was established by the intraperitoneal injection of ovalbumin (OVA). The mice were randomly divided into four groups: control, model, high-dose (H), and low-dose (L) inulin. The mice were administered water containing different concentrations of inulin four weeks before the OVA injection. Body weight changes were monitored. After the last OVA injection, the mice were scored for allergic reactions. The levels of total immunoglobulin E (IgE) and diamine oxidase (DAO) in the serum and secretory IgA (sIgA) in the small intestinal mucus were measured, and 16S rRNA sequencing of the faecal flora was performed to evaluate microbial parameters. The intestinal flora biomarkers, correlations between them, and biochemical indicators were analysed. Inulin treatment had no effect on the body weight of OVA-sensitised mice but attenuated allergic reactions and intestinal injury in mice. Compared with the control group, the model group had significantly higher levels of serum DAO and IgE and significantly lower levels of intestinal mucus IgA. IgA levels in the intestinal mucus of mice treated with inulin prior to OVA sensitisation were higher than those in non-inulin-treated OVA-sensitised mice. Furthermore, analysis of operational taxonomic units showed that inulin treatment decreased the abundance of Alloprevotella, Rikenellaceae RC9, Eubacterium siraeum, and Eubacterium xylanophilum, and increased the abundance of Blautia and Lachnospiraceae. Serum DAO levels were positively associated with Eubacterium siraeum, Alloprevotella, Eubacterium xylanophilum, and Odoribacter and negatively associated with Blautia, Tyzzerella, Alistipes, Desulfovibrionaceae, and Ruminococcaceae UCG005. In addition, IgE levels were positively associated with Eubacterium siraeum, Alloprevotella, Eubacterium xylanophilum, Odoribacter, and Citrobacter and negatively associated with Blautia, unclassified Ruminococcaceae, and Alistipes. IgA exhibited significant positive correlation with Blautia, norank_f_Eubacterium coprostanoligenes, Alistipes, norank Desulfovibrionaceae, Muribaculum, and Ruminococcaceae and significant negative correlation with Eubacterim siraeum, Eubacterium xylanophilum, Odoribacter, and Citrobacter. Inulin exerts a protective effect against food allergies in mice, which is partially mediated by alterations in the gut microbiota.
Use of Specialized Tribunals for the Settlement of Construction Projects in Times of a Financial Crisis
Authors: Abdulrahim Abdulla Mohammad Ibrahim 
Published: September 2023

Abstract
Financial crises have ripple effects throughout several sectors. Both the 2008 financial crisis and the recent covid-19 crisis significantly impacted the financial sector. The government of Dubai devised numerous legislative solutions to the 2008 crisis, one of which was creating special tribunals. The success of the legislative remedies adopted by Dubai’s government during the covid-19 crisis is also worthy of attention. This study aims to draw lessons from both crises in recognition of their considerable potential to serve as remedies during emergencies. Moreover, it seeks to analyze arbitration and insolvency/bankruptcy procedures utilized by specialized tribunals.
Nebulous Cinema
Authors: de Luca Tiago 
Published: September 2023

Abstract
As billowing masses averse to stillness and defined by perpetual variability, clouds, fog and mist share common ontological properties. This article will group them together under the rubric of the “nebulous,” and probe its conceptual and aesthetic relationship with film. Fog, smoke and mist are pervasive through the entire history of cinema and crop up in an array of genres and modes. What would film history look like if traced from the perspective of these cloud forms? The article hopes to sketch out the first contours of such a history by honing in on a durational cinematic tradition, from the “landscape film” of the 1970s through to contemporary slow cinema. It will conceive of such a history as intermedial both in the sense that it extrapolates the boundaries of the film medium and in that it treats fog, mist and clouds as elemental “media” in their own right.
The Export of Goods Used for Torture and the Applicability of Article 3 echr
Authors: Trampert Joëlle 
Published: September 2023

Abstract
Article 3 of the European Convention on Human Rights (echr or Convention) is currently not understood to apply when Council of Europe member states export goods that could be used for torture, the death penalty, or other ill-treatment in third states. In 2021, the Committee of Ministers of the Council of Europe recommended states to take measures against trade in such goods, also recalling Article 3 echr. Following an analysis of relevant rules in the EU Anti-Torture Regulation, the UN Convention Against Torture, and the echr, the paper demonstrates how Article 3 echr may be interpreted so as to apply to export. As the person (at risk of) suffering torture, the death penalty, or other ill-treatment will be located abroad, the paper examines three alternative models for extraterritorial jurisdiction. It concludes that, at a minimum, the Convention could accommodate an obligation to investigate after an export has taken place.
