The use of piezoelectric nanomaterials combined with ultrasound stimulation is emerging as a promising approach for wirelessly triggering the regeneration different tissue types. However, it has never been explored boosting chondrogenesis. Furthermore, parameters used are often not adequately controlled. In this study, we show that adipose-tissue-derived mesenchymal stromal cells embedded in nanocomposite hydrogel containing barium titanate nanoparticles and graphene oxide nanoflakes...
Abstract Articular cartilage (AC) is a specialized connective tissue able to provide low‐friction gliding surface supporting shock‐absorption, reducing stresses, and guaranteeing wear‐resistance thanks its structure mechanical lubrication properties. Being an avascular tissue, AC has limited ability heal defects. Nowadays, conventional strategies show several limitations, which results in ineffective restoration of chondral Several engineering approaches have been proposed restore the AC's...
Abstract Understanding the nature, density, and distribution of structural defects is crucial for tailoring properties atomically thin two‐dimensional (2D) materials, which paramount advances in nanotechnology. Ion irradiation emerges as a promising technique defect engineering single‐atom‐thick due to its high controllability, repeatability, accuracy. The objective provide comprehensive review elucidating impact various parameters, such ion mass, energy, fluence, incident angle, on...
Among the most reliable techniques for exfoliation of two-dimensional (2D) layered materials, sonication-assisted liquid-phase (LPE) is considered as a cost-effective and straightforward method preparing graphene its 2D inorganic counterparts at reasonable sizes acceptable levels defects. Although there were rapid advances in this field, effect outcome sonication frequency are poorly understood often ignored, resulting low efficiency. Here, we demonstrate that simple mild bath higher power...
We report a facile two-furnace APCVD synthesis of 2H-WSe2. A systematic study the process parameters is performed to show formation phase-pure material. Extensive characterization bulk and exfoliated material confirm that 2H-WSe2 layered (i.e., 2D). X-ray diffraction (XRD) confirms phase, while high-resolution scanning electron microscopy (HRSEM), transmission (HRTEM), atomic force (AFM) clarify morphology Focused ion beam (FIB-SEM) estimates depth formed on W foil be around 5-8 μm,...
Recently, graphene and its derivatives have been extensively investigated for their interesting properties in many biomedical fields, including tissue engineering regenerative medicine. Nonetheless, oxide (GO) reduced GO (rGO) are still under investigation improving dispersibility aqueous solutions safety different cell types. This work explores the interaction of rGO with polymeric dispersants, such as glycol chitosan (GC), propylene alginate (PGA), polydopamine (PDA), effects on human...
The high concentration of antibiotics in aquatic environments is a serious environmental issue. In response, researchers have explored photocatalytic degradation as potential solution. Through chemical vapor deposition (CVD), we synthesized copper selenide (β-Cu2−xSe) and found it an effective catalyst for degrading tetracycline hydrochloride (TC-HCl). demonstrated impressive efficiency approximately 98% reaction rate constant 3.14 × 10−2 min−1. Its layered structure, which exposes reactive...
Sunlight-driven photocatalysis is an environmentally friendly approach to solve ecological issues. The development of simple yet sufficiently stable photocatalytic materials capable responding the full-spectrum light remains challenging. Here, we demonstrate phase transformations bulk copper sulfides from digenite (Cu9S5) djurleite (Cu1.97S) and low chalcocite (Cu2S) by reactive thermal annealing during ambient pressure chemical vapor deposition, followed their top-down exfoliation. Using...

Chitosan was used as a surface modifier due to its properties: nontoxicity, biodegradability biocompatibility. adsorption process carried out at room temperature (295 K) pH 7 under static conditions. synthesized sorbent has been characterized scanning electron microscopy (SEM), elemental analysis; the concentrations Pb(II) Cd(II) before after determined using atomic absorption spectroscopy...
Carbon nanomaterials have been introduced as a scaffold for various biological applications due to their unique physical and electrical properties.
Abstract Copper chalcogenides are materials characterized by intrinsic doping properties, allowing them to display high carrier concentrations due their defect‐heavy structures, independent of the preparation method. Such enables these plasmonic resonances, tunable varying stoichiometry. Here, dynamics is studied in drop‐cast Cu 9 S 5 (digenite) nanocrystals (NCs) film using ultrafast pump–probe spectroscopy. The NCs synthesized thermal annealing copper foil chemical vapor deposition (CVD),...
Abstract Osteoarthritis implies a progressive degeneration of the whole joint. Cartilage is particularly affected, with inflammation playing pivotal role1. In recent years, cartilage regeneration has been pursued through several bioengineering strategies and using different stem cell types2-6. Adipose -derived mesenchymal stromal cells (ASCs) constitute an intriguing minimally invasive option. However, use ASCs for hampered by relatively inefficient expression key chondrogenic markers7....
