Vacancies mediated ordering in Ni-Mn-Ga shape memory alloys
(Elsevier, 2022-07-01)
[EN] Vacancy mediated diffusion is the main atomic mechanism that controls the ordering of substitutional alloys. In particular, in Ni-Mn-Ga shape memory alloys vacancies control the evolution of the L21 atomic order degree ...
Metals and metalloids in high-altitude Pyrenean lakes: sources and distribution in pre-industrial and modern sediments
(Springer, 2023-07)
High-altitude Pyrenean lakes are ecosystems far from local pollution sources, and thus they are particularly sensitive to the
atmospheric deposition of metals and metalloids. This study aims to quantify the effect of human ...
Highly hydrophobic cellulose acetate mats modified with poly(ethylene oxide-b-propylene oxide-b-ethylene oxide) triblock copolymer and TiO2 nanoparticles by electrospinning
(2023)
Cellulose acetate (CA) mats modified with poly(ethylene oxide-b-propylene oxide-b-ethylene oxide) (PEO-b-PPO-b-PEO or EPE) and sol–gel synthesised titanium oxide (TiO2) nanoparticles were successfully fabricated by using ...
Chitin Nanofibrils from Fungi for Hierarchical Gel Polymer Electrolytes for Transient Zinc-Ion Batteries with Stable Zn Electrodeposition
(Wiley, 2023-11)
Rechargeable batteries play an integral role toward carbon neutrality. Environmentally sustainable batteries should consider the trade-offs between material renewability, processability, thermo-mechanical and electrochemical ...
Desymmetrization of Oxabenzonorbornadienes through Brønsted Acid-Catalyzed Enantioselective (3+2) Cycloaddition with Hydrazones
(Wiley, 2023-07)
This work presents the desymmetrization of oxabenzonorbornadienes through the (3+2) cycloaddition reaction with hydrazones using a chiral Brønsted acid such as a BINOL-derived phosphoramide. This chiral acid catalyst appears ...
European Grapevine Cultivars and Rootstocks Show Differential Resistance to Xylella fastidiosa Subsp. fastidiosa
(MDPI, 2023-11-12)
Several Xylella fastidiosa subsp. fastidiosa (ST1) strains that cause Pierce’s disease were isolated from grapevine in Spain. In this study, we applied an approach to assess PD susceptibility among 24 different well-known ...
Neuroinflammation in the Evolution of Motor Function in Stroke and Trauma Patients: Treatment and Potential Biomarkers
(MDPI, 2023-10-25)
Neuroinflammation has a significant impact on different pathologies, such as stroke or spinal cord injury, intervening in their pathophysiology: expansion, progression, and resolution. Neuroinflammation involves oxidative ...
White Blood Cell Classification: Convolutional Neural Network (CNN) and Vision Transformer (ViT) under Medical Microscope
(MDPI, 2023-11-15)
Deep learning (DL) has made significant advances in computer vision with the advent of vision transformers (ViTs). Unlike convolutional neural networks (CNNs), ViTs use self-attention to extract both local and global ...
Chronological detection of depression in social media threads by means of natural language processing
(2023-11-28)
Detecting depression in social media has become an increasingly important research area
in recent years. With the widespread use of social media platforms, individuals at risk of
suicide often express their thoughts and ...
