Scanning electron microscopy coupled energy-dispersive X-ray...
Nowadays, the use of marine by-products as precursor materials has gained great interest in extraction and production chemical compounds with suitable properties possible pharmaceutical applications. The present paper presents development a new immediate release tablet containing calcium lactate obtained from Black Sea mussel shells. Compared other salts, good solubility bioavailability. In preparations, was extensively utilized source for preventing treating deficiencies. physical...
Captopril is the first angiotensin I-converting enzyme inhibitor widely used for treatment of hypertension. Based on well-known benefits cyclodextrin inclusion complexes, present study investigated ability β-cyclodextrin to include captopril. Solid complexes captopril with in a 1:2 molar ratio were prepared by using paste method complexation. For comparison purposes, simple physical mixture same was also prepared. Fourier-transform infrared spectroscopy, scanning electron microscopy, X-ray...
Finding innovative solutions to improve the lives of people affected by trauma, bone disease, or aging continues be a challenge worldwide. Tissue engineering is most rapidly growing area in domain biomaterials. Cerium-containing MBG-derived biomaterials scaffolds were synthesized using polymethyl methacrylate (PMMA) as sacrificial template. The obtained characterized X-ray powder diffraction (XRPD), infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Ce4+/Ce3+ ratio was...
Ti-aluminosilicate gels were used as supports for the immobilization of Fe, Co, and Ni oxides (5%) by impregnation synthesis efficient photocatalysts degradation β-lactam antibiotics from water. Titanium oxide (1 2%) was incorporated into zeolite network modifying gel during zeolitization process. The formation Y structure its microporous evidenced X-ray diffraction N2 physisorption. structure, composition, reduction, optical properties studied diffraction, H2-TPR, XPS, Raman,...
Ag nanoparticles (AgNPs) were biosynthesized using sage (Salvia officinalis L.) extract. The obtained supported on SBA-15 mesoporous silica (S), before and after immobilization of 10% TiO2 (Degussa-P25, STp; commercial rutile, STr; synthesized from Ti butoxide, STb). formation AgNPs was confirmed by X-ray diffraction. plasmon resonance effect, evidenced UV-Vis spectra, preserved only for the sample STb. dispersion properties supports TEM microscopy, energy-dispersive X-rays, dynamic light...
Ammonia is one of the common inorganic pollutants in surface waters. It can come from a wide range sources through discharge wastewater (industry, agriculture, and municipal waters). Catalytic ozonation reaction efficiently remove ammonia nitrogen without introducing other improve selectivity products by controlling conditions. Catalysts based on silver nanoparticles (Ag NPs) have shown excellent O3 decomposition performance; therefore, they are promising catalysts for catalytic due to their...
Malignant skin conditions are classified as the most common forms of cancer, with an evolution one million new cases reported every year. Research efforts in medical field focused on developing innovative strategies for dissemination measures preventing cancer and providing antitumor compounds. The present research examines development evaluation 1% Carbopol-based hydrogels incorporating two porphyrin derivatives—5,10,15,20-tetrakis-(4-acetoxy-3-methoxyphenyl) (P2.1)...
Reconstruction of extensive bone defects due to age, trauma, or post-illness conditions remains challenging. Biomimetic scaffolds with osteogenic capabilities have been proposed as an alternative the classical autograft and allograft implants. Three-dimensional were obtained based on Ce-doped mesoporous bioactive glass (MBG) Spongia agaricina (SA) sacrificial templates functionalized vitamin D3. The study aimed investigate effect D3 functionalization optimal variant a 3D scaffold doped 3...

This paper describes the preparation of new PEG6000–silica-MWCNTs composites as shape-stabilized phase change materials (ssPCMs) for application in latent heat storage. An innovative method was employed to obtain organic–inorganic hybrid materials, which both a part PEG chains, used material, and hydroxyl functionalized multiwall carbon nanotubes (MWCNTs-OH), thermo-conductive fillers, were covalently connected by newly formed urethane bonds in-situ-generated silica matrix. The study’s main...
Development of efficient controlled local release drugs that prevent systemic side effects is a challenge for anti-osteoporotic treatments. Research new bone-regeneration materials high importance. Strontium (Sr) known as an anti-resorptive and anabolic agent useful in treating osteoporosis.
