Nanocomposites based on CuO coated silver nanowire networks for high-performance oxygen evolution reaction.

The development of highly active, low-cost, and robust electrocatalysts for the oxygen evolution reaction (OER) is a crucial endeavor for the clean and economically viable production of hydrogen electrochemical water splitting. Herein, cuprous oxide (CuO) thin films are deposited on silver nanowire (AgNW) networks by atmospheric-pressure spatial atomic layer deposition (AP-SALD). AgNW@CuO nanocomposites supported on conductive copper electrodes exhibited superior OER activity as compared to bare copper substrate and bare AgNWs.

Pes anserine bursitis as a complication of tibial osteochondroma.

Exostosis, or osteochondroma, represents the most prevalent primary benign bone tumor, often viewed as a developmental anomaly rather than a true neoplasm. This article presents 2 cases illustrating complications associated with tibial osteochondroma. The first case involves a 25-year-old patient with recurrent medial knee pain attributed to pes anserine bursitis secondary to tibial osteochondroma, managed successfully with surgical excision.

Ileal intussusception secondary to lipoma in an adult patient: A rare cause for intestinal obstruction: A case report.

Intussusception is a rare condition in adults, unlike in children, with a variety of etiologies. In most cases, it is secondary to tumors. acute intussusception on lipoma is very exceptional.

Assessing the Environmental Impact of Atomic Layer Deposition (ALD) Processes and Pathways to Lower It.

Due to concerns on resources depletion, climate change, and overall pollution, the quest toward more sustainable processes is becoming crucial. Atomic layer deposition (ALD) is a versatile technology, allowing for the precise coating of challenging substrates with a nanometer control over thickness. Due to its unique ability to nanoengineer interfaces and surfaces, ALD is widely used in many applications.

Can We Rationally Design and Operate Spatial Atomic Layer Deposition Systems for Steering the Growth Regime of Thin Films?

Fine control over the growth of materials is required to precisely tailor their properties. Spatial atomic layer deposition (SALD) is a thin-film deposition technique that has recently attracted attention because it allows producing thin films with a precise number of deposited layers, while being vacuum-free and much faster than conventional atomic layer deposition. SALD can be used to grow films in the atomic layer deposition or chemical vapor deposition regimes, depending on the extent of precursor intermixing.

Chemical deposition of CuO films with ultra-low resistivity: correlation with the defect landscape.

Cuprous oxide (CuO) is a promising p-type semiconductor material for many applications. So far, the lowest resistivity values are obtained for films deposited by physical methods and/or at high temperatures (~1000 °C), limiting their mass integration. Here, CuO thin films with ultra-low resistivity values of 0.

Atmospheric atomic layer deposition of SnO thin films with tin(II) acetylacetonate and water.

Due to its unique optical, electrical, and chemical properties, tin dioxide (SnO) thin films attract enormous attention as a potential material for gas sensors, catalysis, low-emissivity coatings for smart windows, transparent electrodes for low-cost solar cells, . However, the low-cost and high-throughput fabrication of SnO thin films without producing corrosive or toxic by-products remains challenging. One appealing deposition technique, particularly well-adapted to films presenting nanometric thickness is atomic layer deposition (ALD).

A comparative study of semantic segmentation of omnidirectional images from a motorcycle perspective.

The semantic segmentation of omnidirectional urban driving images is a research topic that has increasingly attracted the attention of researchers, because the use of such images in driving scenes is highly relevant. However, the case of motorized two-wheelers has not been treated yet. Since the dynamics of these vehicles are very different from those of cars, we focus our study on images acquired using a motorcycle.

Silver Nanowire Networks: Ways to Enhance Their Physical Properties and Stability.

Silver nanowire (AgNW) networks have been intensively investigated in recent years. Thanks to their attractive physical properties in terms of optical transparency and electrical conductivity, as well as their mechanical performance, AgNW networks are promising transparent electrodes (TE) for several devices, such as solar cells, transparent heaters, touch screens or light-emitting devices. However, morphological instabilities, low adhesion to the substrate, surface roughness and ageing issues may limit their broader use and need to be tackled for a successful performance and long working lifetime.

Effects of non-homogeneity and oxide coating on silver nanowire networks under electrical stress: comparison between experiment and modeling.

Silver nanowire (AgNW) networks are among the most promising indium-free, flexible transparent electrodes for energy, lighting and heating devices. However, the lack of stability of such networks is a key factor that limits their industrial application. While applications require homogeneous networks, non-homogeneous AgNW networks are intentionally prepared in the present work to probe the mechanisms leading to failure under electrical stress.

Planar and Transparent Memristive Devices Based on Titanium Oxide Coated Silver Nanowire Networks with Tunable Switching Voltage.

Threshold switching devices are fundamental active elements in more than Moore approaches, integrating the new generation of non-volatile memory devices. Here, the authors report an in-plane threshold resistive switching device with an on/off ratio above 10 , a low resistance state of 10 to 100 kΩ and a high resistance state of 10 to 100 GΩ. Our devices are based on nanocomposites of silver nanowire networks and titanium oxide, where volatile unipolar threshold switching takes place across the gap left by partially spheroidized nanowires.

Pulmonary and intracranial miliary tuberculosis secondary to Behçet's anti-TNF alfa treatment.

Behçet disease is a rare vasculitis that affects vessels of different body parts, causing different kinds of manifestations. We report a case of a 47 years old woman who had a tumor necrosis factor alfa blocker prescription due to a Behçet's disease relapse. The patient then developed a cerebral and pulmonary tuberculous miliary due to immunodeficiency.

EPIMAG: International Cross-Sectional Epidemiological Psoriasis Study in the Maghreb.

Background: Psoriasis is a common skin disorder that is characterized by red plaques covered with silvery scales and is associated with considerable psychosocial impact. It has been described in several studies worldwide, but specific data from the Maghreb (Algeria, Morocco and Tunisia) are unavailable.

Objectives: To characterize the frequency of new psoriasis cases and to describe the epidemiological and clinical profile of psoriasis in the Maghreb.

[Urethral discharge in Morocco: prevalence of microorganisms and susceptibility of gonococcos].

We studied 422 patients with urethral discharge recruited from 4 sentinel sites in Morocco to determine sociodemographic characteristics, history of STI infection, infecting organism and antibiotic susceptibility of Neisseria gonorrhoeae. The mean age of the sample was 28 years (range 16-67 years), and most were single, had multiple sex partners without taking protective measures and came from all social backgrounds; 59.9% had a history of a previous STI.

The authors, in a series of 65 cases of Behçet's disease, notice 53% of rheumatological manifestations which are third in line after aphthosis and ocular disease. In order of decreasing frequency, it concerns arthritis (mono, oligo or poly-arthritis), arthralgias with an almost identical frequency, sacroiliitis, extraarticular involvement. These rheumatological manifestations are readily associated with necrotic pseudo-folliculitis and cutaneous aphthosis.
