Anton FICAI is a young professor with habilitation involved in both academic and scientific life of the University POLITEHNICA of Bucharest and Academy of Romanian Scientists. His major academic interests are related to the coordination of the teaching activities related to the classes: Chemistry, Chemistry and Characterization of Materials, Composite Materials for Medicine, NaoBioMaterials for Tissue Engineering  and Drug Delivery Systems. The research interests are much broader and cover the following topics: tissue engineering; drug delivery systems; multifunctional materials; composite materials; antimicrobial / antitumoral materials; nanoparticles synthesis and characterization; coatings and surface modification; etc. Till now, over 300 scientific papers, from which 270 ISI papers and 18 books or chapters (including 2 edited books) were published along with 28 patent applications (8 of them being already released) and attracting over 3000 citations and a Hirsh index of 30.



Drug delivery systems are increasingly studied or even used for a wide range of biomedical applications [1-3]. Internal or external factors can be used to tune the delivery of the biologically active agents and thus to assure the optimal conditions. Micro and Mesoporous materials are widely used as drug delivery system because they can assure the desired controlled release of a wide range of biologically active agents. Usually, mesoporous silica exhibit large surface area and good surface reactivity to be easily functionalized and thus to assure the desired delivery profile considering especially surface modification, pores' characteristics, and triggering factors.

Starting from the advantages of the mesoporous silica supports, innovative drug delivery systems can be developed in order to obtain targeted drug delivery systems. In this work, several examples of drug delivery systems based on mesoporous silica and different polyphenols will be discussed.

Shape memory effect is a peculiar property exhibited a series of alloy system called shape memory alloys, which have dual characteristics called thermoelasticity and superelasticity, from viewpoint of memory behavior. These alloys take place in class of advanced novel materials with these properties and response to the external conditions. Two successive crystallographic transformations, thermal and stress induced martensitic transformations govern these phenomena in crystallographic basis. Shape memory effect is performed thermally in a temperature interval on heating and cooling after first cooling and, this behavior can be called thermal memory or thermoelasticity. Superelasticity is performed mechanically by stressing and releasing at a constant temperature in the parent austenite phase region of materials, and this behavior can be called mechanical memory.

Thermal induced martensite occurs along with lattice twinning and ordered parent phase structures turn into multivariant twinned martensite structures in self-accommodating manner, and twinned martensite structures turn into detwinned martensite by means of stress induced martensitic transformation on stressing. Superelasticity is performed by stressing material and releasing in a constant temperature in parent phase region and performed simultaneously upon releasing the applied stress. This phenomenon is performed in non-linear way; stressing and releasing paths are different in the stress-strain diagram, and hysteresis loop refers to energy dissipation.

The elementary processes involved in such martensitic transformations are essentially shear deformations, lattice invariant shears, and shuffling of atomic planes. Lattice invariant shears occur with cooperative movements of atoms on close packed planes of ordered parent phase lattice in displacive manner. The atomic plane shuffling and shearing can be considered as elementary processes activated during displacive martensitic transformations. Lattice invariant shear and lattice twinning is not uniform in copper-based shape memory alloys, and cause to the formation of long-period layered complex martensitic structures with lattice twinning on cooling.

Electron diffraction and x-ray diffraction studies performed on copper based CuZnAl and CuAlMn alloys. X-Ray diffraction profiles taken from the alloy samples exhibit superlattice reflections. Critical transformation temperatures of these alloys are over room temperature, and they are in fully martensitic state at room temperature. A series of x-ray diffractions were taken duration aging at room temperature. Diffraction results show that diffraction angles and peak intensities change with aging. This result refers to a new reaction in diffusive manner.

In this work, nitrogen and phosphorus co-doped reduced graphene oxide (N, P-rGO) nanohybrids has been synthesized using one pot greener in situ method using cytidine monophosphate as a dopant/reducing agent. This material has been characterized by various techniques such as UV-Vis, Raman, FE-SEM, TEM and thermal methods (TGA). The stability of N, P-rGO as an electrode material and the high operational potential window of 2.7 V (from -1.4 to 1.3 V) was achieved in three-electrode setup after running 150 electrochemical cyclic voltammetry (CV) cycles in neutral WIS 17 m NaClO4 electrolyte. Two-electrode aqueous symmetric supercapacitor (SSC) (N, P-rGO//N, P-rGO), designed by using CMP-mediated N, P-rGO as electrode material in neutral WIS 17 m NaClO4 electrolyte provided a fairly high energy density of 42.2 Wh Kg-1 at a power density of 315.2 W Kg-1 at 0.7 Ag-1 with superior cyclic stability, making it sustainable for energy storage applications. The ClO4- anion has been suggested to act as an effective H-bond net-work breaker for the bulk water, thereby, enhancing the cell voltage to 2.7 V. To the best of our knowledge, this system demonstrates a very high cell voltage for N, P-co-doped reduced graphene oxide with a high energy density.

Excellent and superior properties of alumina (Al2O3) nanocrytalline ceramic make it a one of the highly demanded advanced ceramics in the present competitive scenario of manufacturing and industrial applications. α-Αl2O3 nanoparticles with average particle size of 3.4, 5.2, 7.2 and 12.5 nm a series of Αl2O3 nanocrystalline ceramic samples were prepared by grain size variation. (Two-step sintering). The inverse Hall Pitch relationship between the microhardness and grain size of Αl2O3 nanocrystalline ceramic was observed. Critical grain size exists at which the properties of α- Αl2O3 nanocrystalline ceramics change significantly. Indentation method was employed to test the fracture toughness of Αl2O3 nanocrystalline ceramic. When the grain size decreased from 297 nm to 33 nm, the fracture toughness increased from 3.04±0.19 to 4.52±0.13 MPa∙m1/2. The enhance of the diffusional creep rate and grain-boundary may be the causes of the improvement of fracture toughness. The maximum microhardness of α- Αl2O3 Nanocrystalline ceramics (NCCs) with grain size is 22.32 GPa. Microstructure evaluation study of alumina Nanocrytalline ceramics is carried out by SEM, TEM and EDX. To study the microhardness and fracture toughness of alumnian nanocrytalline ceramics Vickers hardness test is performed. Further focusing on Investigate the behavior of positive and negative Hall pitch behavior by experimental and theoretical model results and evaluate the deformation mechanisms of alumina Nanocrystalline ceramics.

As society has developed, nanoparticles have had a profound impact. Recently, the energy sector has benefited from the synthesis of transition metal nanoparticles and their phosphates. In this manuscript, the performances of nickel-cobalt phosphate nanoparticles produced via coprecipitation were examined. The morphology, structural, optical, and electrochemical features of the produced nanoparticles were determined using scanning electron microscopy (SEM), X-ray diffractometry (XRD), UV-vis spectrophotometer, and a 3-electrode potentiostat, respectively. The SEM and XRD data revealed nanospikes and crystalline structures. The optical data revealed that when the molar concentrations increased, the particles' absorbance increased and their band gap energy (3 eV) decreased. The nanoparticles' charge-storage capacity was discovered through electrochemical experiments. In the future, the particles produced may be used in supercapacitors.
