Abstract A three‐phase [nanocrystalline hydroxyapatite (HA), carbon nanotubes (CNT), mixed in a polymeric matrix of polycaprolactone (PCL)] composite scaffold produced by 3D printing is presented. The CNT content varied between 0 and 10 wt % 50 PCL matrix, with HA being the balance. With combination three well‐known materials, these scaffolds aimed at bringing together properties all into unique material to be used tissue engineering as support for cell growth. technique allows producing...
Accurate determination of the effective doping range within diamond thin films is important for fine-tuning electrical conductivity. Nevertheless, it not easily attainable by commonly adopted techniques. In this work, pulsed RF glow discharge optical emission spectrometry (GD-OES) combined with ultrafast sputtering (UFS) applied first time to acquire elemental depth profiles intrinsic coatings and boron content bulk distribution in films. The GD-OES practical advances presented here enabled...
Abstract The interfacial topography of biomaterials has been identified as a major biophysical regulator cell behavior and function, role played through the interplay with biochemical cues. In this work, we demonstrate potential laser versatile technology for direct fine-tuning Bacterial nanocellulose (BNC) bioinspired topographies micropatterns on size scale. Two lasers were used, different wavelengths—IR (CO 2 , 10600 nm) UV (tripled Nd: YVO 4 355 —attempting to reproduce Pitcher-plant...

Abstract The ability to fabricate materials with ultrathin architectures enables the breakthrough of low‐dimensional structures high surface area that showcase distinctive properties from their bulk counterparts. They are exploited in a wide range fields, including energy harvesting, catalysis, and biomedicine. Despite such versatility, fine tuning lateral dimensions geometry these remains challenging. Prepatterned platforms gain significant attention as enabling technologies process highly...
Diamond-based electrodes and biosensors are interesting in analytics because of their particular set properties, namely: large potential window, chemical inertness, low baseline current, stability, transparency. were shown to detect biological molecules such as neurotransmitters proteins, respectively. In this review, we summarise the different types diamond based on type detection (electrochemical or optical), functionalisation, target analyte. The last section presents a discussion...
The functionalization of nanographene oxide (GO) with polymers is desirable for increasing the interface compatibility GO, thereby enabling its use in a variety applications such as biomedical and energy storage systems. Typically, wet chemistry processes are used to achieve polymer having limitations high heterogeneity, time consumption, difficult purification processes. Two approaches dry nano-GO surface therefore proposed, utilizing an atomic layer deposition (ALD) reactor: (i)...
Cobalt-cemented carbide micro-end mills were coated with diamond grown by chemical vapor deposition (CVD), the purpose of micro-machining cemented carbides. The coatings designed a multilayer architecture, alternating between sub-microcrystalline and nanocrystalline layers. structure was studied transmission electron microscopy. High adhesion to chemically pre-treated WC-7Co tool substrates observed Rockwell C indentation, withstanding critical load 1250 N. tools tested for micro-end-milling...
