Abstract The precise control over the interaction between cells and surface of materials plays a crucial role in optimizing integration implanted biomaterials. In this regard, material with controlled topographic features at micro- nano-scales has been proved to affect overall cell behavior therefore final osseointegration implants. Within context, femtosecond (fs) laser micro/nano machining technology was used work modify structure stainless steel aiming controlling adhesion migration....
Owing to the confined Fe-3d orbitals and self-interaction error of exchange-correlation functionals, approximate DFT fails describe iron oxides electronic structure magnetic properties accurately. Hybrid or + U can solve these problems, but former is expensive, latter only considers on-site interactions. Here, we used V, a extension including inter-site interactions, simulate structural, magnetic, properties, along with Fe O K-edge XAS spectra α-Fe2O3. Two types atomic orbital projectors...
The increasing demand for portable electronic devices and batteries has led to a growing interest in Li compounds. Lithium manganese oxides (LMO) are the most popular lithium-ion sieves (LIS) precursor materials due their high lithium adsorption capacity selectivity. key step forming LIS is desorption process from crystalline lattice of LMO. However, this been less researched than its counterpart, process. In line, there some studies describing acid media spinel-type Nevertheless, no...
In this paper a method for fabricating nanostructured polymeric surfaces with contrasted chemical functionality is presented. First, polymer film of acrylic acid (PAA) deposited by plasma enhanced vapor deposition. It covered monolayer particles in the 500 nm range. Then oxygen etching performed, providing both nanoparticles and present between masks. The process stopped before complete residual ones are removed ultrasonic bath. Chemical contrast thus created nanodomes having plateau-like...
Ag2S nanoparticles are the staple for high-resolution preclinical imaging and sensing owing to their photochemical stability, low toxicity, photoluminescence (PL) in second near-infrared biological window. Unfortunately, exhibit a PL efficiency attributed defective surface chemistry, which curbs translation into clinics. To address this shortcoming, we present simple methodology that allows improve quantum yield from 2 10%, is accompanied by lifetime lengthening 0.7 3.8 μs. Elemental mapping...
Today, diabetes mellitus is one of the most common diseases that affects population on a worldwide scale. Patients suffering from this disease are required to control their blood-glucose levels several times day through invasive methods such as piercing fingers. Our NaGdF4: 5% Er3+, 3% Nd3+ nanoparticles demonstrate remarkable ability detect D-glucose by analysing alterations in red-to-green ratio, since sensitivity arises interaction between and OH groups present molecules, resulting...
Iron-based nanoparticles have emerged as promising candidates for diverse biomedical applications, including cell separation, targeted drug delivery, hyperthermia therapy, and magnetic resonance imaging. This study reports the scalable synthesis of high-magnetization iron-based with controlled anisotropic shapes, achieved via a two-step process. Hematite nanoparticles, featuring nanocube, nanoellipse, nanoneedle morphologies, were synthesized through hydrolysis ferric chloride in presence...
The increasing availability of semiconductor-based nanostructures with novel and unique properties has sparked widespread interest in their use the field biosensing. precise control over size, shape composition these leads to accurate physico-chemical overall behavior. Furthermore, modifications can be made better suit integration biological systems, leading such interesting as enhanced aqueous solubility, biocompatibility or bio-recognition. In present work, most significant applications...
In this report, we have used the DFT + U V approach, an extension of approach that takes into account both on-site and intersite interactions, to simulate structural, magnetic, electronic properties together with Fe O K-edge XAS spectra Fe3O4 above Verwey temperature (Tv). Moreover, compared simulated experimental data. We examined orthogonalized nonorthogonalized atomic orbital projectors DFT, U, HSE as a hybrid functional. It is noteworthy that, despite widespread use same Hubbard value...
Electrodeposition of gold into porous silicon was investigated. In the present study, with ~100 nm in pore diameter, so-called medium-sized pores, used as template electrode for electrodeposition. The growth behavior deposits studied by scanning electron microscope observation deposited silicon. Gold nanorod arrays different rod lengths were prepared, and their surface-enhanced Raman scattering properties We found that absorption peak due to surface plasmon resonance can be tuned changing...
