Probing the Metal/Oxide Interface of IrCoCeO in NH·HO Decomposition: An Experimental and Computational Study.

Understanding the structure of a functional catalyst is crucial to disclosing the complexity of heterogeneous processes and improving their efficiency. Herein, coprecipitated cobalt-ceria (CoCeO) oxides doped with Ir (IrCoCeO) were synthesized and used to assess the performances of metal/oxide interfaces in the NH·HO decomposition performed in aqueous NaOH. Kinetic experiments in batch showed that CoO is the active phase of CoCeO and that the copresence of Ir and Co (IrCoCeO) enhanced H productivity.

Operando Spectroscopy of Catalysts Exploiting Multi-technique and Modulated Excitation Approaches.

Operando spectroscopy combines the in situ determination of material structure by spectroscopy/diffraction techniques with the measurement of material performance, which is conversion/selectivity in the field of heterogeneous catalysis. A central question in operando spectroscopy is whether the signatures visible by the characterization methods are responsible for catalyst performance. Individual analytical methods can provide useful information, but their combination (multi-technique approach) is essential to obtain a complete perspective on molecular reaction mechanisms.

Can the endometrioma be an obstacle to complete oocyte retrieval in IVF cycles? A retrospective study.

Objective: The study aimed to evaluate the utility and safety of ancillary maneuvers during oocyte retrieval for patients with endometrioma that makes ovum pick-up hard due to poor ovarian surgical accessibility.

Patients And Methods: Cases of 251 women with ovarian endometriomas undergoing in vitro fertilization (IVF) in our infertility unit were retrospectively analyzed to evaluate the clinical IVF cycle outcomes after oocyte retrieval. Controls (n = 251) were age-matched women without endometriomas who underwent an uncomplicated oocyte retrieval.

Neurophysiological markers of asymmetric emotional contagion: implications for organizational contexts.

Emotions play a vital role within organizations, impacting various crucial aspects of work such as job satisfaction, performance, and employee well-being. Understanding how emotional states spread in organizational settings is therefore essential. Recent studies have highlighted that a leader's emotional state can influence their followers, with significant consequences on job performance.

Machine Learning for Quantitative Structural Information from Infrared Spectra: The Case of Palladium Hydride.

Infrared spectroscopy (IR) is a widely used technique enabling to identify specific functional groups in the molecule of interest based on their characteristic vibrational modes or the presence of a specific adsorption site based on the characteristic vibrational mode of an adsorbed probe molecule. The interpretation of an IR spectrum is generally carried out within a fingerprint paradigm by comparing the observed spectral features with the features of known references or theoretical calculations. This work demonstrates a method for extracting quantitative structural information beyond this approach by application of machine learning (ML) algorithms.

In Situ Neutron Diffraction of Zn-MOF-74 Reveals Nanoconfinement-Induced Effects on Adsorbed Propene.

Even though confinement was identified as a common element of selective catalysis and simulations predicted enhanced properties of adsorbates within microporous materials, experimental results on the characterization of the adsorbed phase are still rare. In this study, we provide experimental evidence of the increase of propene density in the channels of Zn-MOF-74 by 16(2)% compared to the liquid phase. The ordered propene molecules adsorbed within the pores of the MOF have been localized by in situ neutron powder diffraction, and the results are supported by adsorption studies.

Improving time-resolution and sensitivity of X-ray photoelectron spectroscopy of a powder catalyst by modulated excitation.

Ambient pressure X-ray photoelectron spectroscopy (APXPS) is a powerful tool to characterize the surface structure of heterogeneous catalysts . In order to improve the time resolution and the signal-to-noise (S/N) ratio of photoemission spectra, we collected consecutive APXP spectra during the periodic perturbation of a powder Pd/AlO catalyst away from its equilibrium state according to the modulated excitation approach (ME). Averaging of the spectra along the alternate pulses of O and CO improved the S/N ratio demonstrating that the time resolution of the measurement can be limited solely to the acquisition time of one spectrum.

Barriers to cultural participation by people with disabilities in Europe: a study across 28 countries.

This article discusses the findings of a new qualitative study conducted in 28 European countries, examining barriers to cultural participation as perceived by representatives of organisations of people with disabilities. The study explores barriers operating in all art-forms as well as in cultural heritage, and it encompasses participation of people with a broad range of disability types both as audiences and as creators of culture. The article evidences that a range of interlinked barriers are commonly perceived by people with disabilities in five areas - lack of effective laws and policies; inadequate services and/or funding; negative attitudes; lack of accessibility; and lack of involvement of persons with disabilities in cultural organisations.

Diffuse reflectance infrared spectroscopy of adsorbates in liquid phase.

Infrared spectroscopy is widely used to analyse the surface of solid materials central to modern chemical processes. For liquid phase experiments, the attenuated total reflection mode (ATR-IR) requires the use of waveguides that can limit a broader applicability of the technique for catalysis studies. Here, we demonstrate that high quality spectra of the solid-liquid interface can be collected in diffuse reflectance mode (DRIFTS) thus opening future applications of infrared spectroscopy.

Immersive Virtual Reality and Cadaveric Bone are Equally Effective in Skeletal Anatomy Education: A Randomized Crossover Noninferiority Trial.

Objective: Immersive virtual reality (IVR) technology is transforming medical education. Our aim was to compare the effectiveness of IVR with cadaveric bone models in teaching skeletal anatomy.

Design: A randomized crossover noninferiority trial was conducted.

A successful twin healthy live birth achieved from eggs with a rare perivitelline space abnormality: A case report.

Background: Phenotypic dysmorphism is not rare to be found in the human oocyte, especially in the perivitelline space, which are among the most important aberration of the extra cytoplasmic component.

Case Presentation: The case is of a 30-yr-old woman with no previous pregnancy, attempting an in vitro fertilization treatment for the first time. Given the extraordinary quantity of granular particles found in the perivitelline space, visible after the stripping procedure, it was not possible to establish the presence and position of the first polar body to appreciate the correct oocyte maturation (metaphase 2).

Congenic hematopoietic stem cell transplantation promotes survival of heart allografts in murine models of acute and chronic rejection.

The ability to induce tolerance would be a major advance in the field of solid organ transplantation. Here, we investigated whether autologous (congenic) hematopoietic stem cell transplantation (HSCT) could promote tolerance to heart allografts in mice. In an acute rejection model, fully MHC-mismatched BALB/c hearts were heterotopically transplanted into C57BL/6 (CD45.

Surface species in direct liquid phase synthesis of dimethyl carbonate from methanol and CO: an MCR-ALS augmented ATR-IR study.

The reaction mechanism of dimethyl carbonate (DMC) production over ZrO from CO and CHOH is well-known, but the level of understanding has not improved in the last decade. Most commonly, the reaction mechanism has been explored in the gas phase, whilst DMC production occurs in the liquid phase. To overcome this contradiction, we exploited ATR-IR spectroscopy to study DMC formation over ZrO in the liquid phase.

The Polymorphism Asn680Ser on the FSH Receptor and Abnormal Ovarian Response in Patients with Normal Values of AMH and AFC.

After the controlled ovarian stimulation (COS), the number of cumulus oocyte complexes collected is lower than predicted. The aim of this study is to understand if there is a possible reason for that deficient ovarian response. It was hypothesized that this is associated with the SNP (single-nucleotide polymorphism) of the FSH receptor (FSHr), specifically c.

Enhancing Access to Digital Culture for Vulnerable Groups: The Role of Public Authorities in Breaking Down Barriers.

This article discusses which barriers hamper access to, and participation in, cultural life for members of vulnerable groups, in particular persons belonging to old and new minorities and persons with disabilities in the context of digitization. It then examines what role public authorities can play in addressing and dismantling these barriers. The article adopts a bottom-up approach, in that it is based on a qualitative study, which gives voice to vulnerable groups.

Bringing social interaction at the core of organizational neuroscience.

Organizations are composed of individuals working together for achieving specific goals, and interpersonal dynamics do exert a strong influence on workplace behaviour. Nevertheless, the dual and multiple perspective of interactions has been scarcely considered by Organizational Neuroscience (ON), the emerging field of study that aims at incorporating findings from cognitive and brain sciences into the investigation of organizational behaviour. This perspective article aims to highlight the potential benefits of adopting experimental settings involving two or more participants (the so-called "second person" approach) for studying the neural bases of organizational behaviour.

The Remapping of Peripersonal Space in a Real but Not in a Virtual Environment.

One of the most surprising features of our brain is the fact that it is extremely plastic. Among the various plastic processes supported by our brain, there is the neural representation of the space surrounding our body, the peripersonal space (PPS). The effects of real-world tool use on the PPS are well known in cognitive neuroscience, but little is still known whether similar mechanisms also govern virtual tool use.

Beware of beam damage under reaction conditions: X-ray induced photochemical reduction of supported VO catalysts during XAS experiments.

X-ray absorption spectroscopy (XAS) is a powerful technique for the investigation of heterogeneous catalysts and electrocatalysts. The obtained XAS spectra are usually interpreted from the point of view of the investigated chemical processes, thereby sometimes omitting the fact that intense X-ray irradiation may induce additional transformations in metal speciation and, thus, in the corresponding XAS spectra. In this work, we report on X-ray induced photochemical reduction of vanadium in supported vanadia (VO) catalysts under reaction conditions, detected at a synchrotron beamline.
