Mitochondria-Targeted Drug in Cardiovascular Disease
Cardiovascular disease (CVD) represents a major threat for human health. The available preventive and treatment interventions are insufficient to revert the underlying pathological processes, which underscores the urgency of alternative approaches. Mitochondria dysfunction plays a key role in the etiopathogenesis of CVD and is regarded as an intriguing target for the development of innovative therapies. Oxidative stress, mitochondrial permeability transition pore opening, and excessive fission are major noxious pathways amenable to drug therapy. Thanks to the advancements of nanotechnology research, several mitochondria-targeted drug delivery systems (DDS) have been optimized with improved pharmacokinetic and biocompatibility, and lower toxicity and antigenicity for application in the cardiovascular field.

XPS Study Calcining Mixtures of Brucite with Titania
The X-ray stimulation photospectrometry technique known as XPS is applied to determine chemical bond characteristics of organic and inorganic substances. On the other hand, the processes of chemical substance formation can be energetically activated by various mechanisms, one of them being thermal activation. Magnesium oxide (magnesia, MgO) and titanium oxide (titania, TiO2) are substances that, due to their chemical and energetic nature, can chemically react to form other chemical compounds when subjected to relatively high temperatures. During the sintering of MgO it is feasible to use some additives such as TiO2 to improve some properties, but during the process it is possible the formation of substances that limit its final application at high temperature. This review focuses on the relatively high-temperature synthesis and characterization of compounds based on MgO:TiO2 in a 50:50 wt% ratio, using the XPS technique and supported by XRD.

Seaweed Phenolics
Seaweed, also referred to as macroalgae, have been studied as potential aquafeed ingredients since the late 1970s but have been implemented as a poultry feed supplement since the 1950s. Seaweed phenolics provide alternative ingredients that are complementary to synthetic additives used in aquaculture, possessing a broad spectrum of bioactive properties such as antimicrobial, antiviral, antifungal, anti-stress, antioxidant, anti-inflammatory, immunostimulant, and appetite stimulation. Also, their antioxidant properties retard lipid oxidation and preserve feed quality improving shelf life.

3DP Medicines and Medical Devices
Novel additive manufacturing (AM) techniques and particularly 3D printing (3DP) have achieved a decade of success in pharmaceutical and biomedical fields. Highly innovative personalized therapeutical solutions may be designed and manufactured through a layer-by-layer approach starting from a digital model realized according to the needs of a specific patient or a patient group. The combination of patient-tailored drug dose, dosage, or diagnostic form (shape and size) and drug release adjustment has the potential to ensure the optimal patient therapy. This document provides an overview on different 3DP techniques to produce personalized medicines and medical devices, highlighting, for each method, the critical printing process parameters, the main starting materials, as well as advantages and limitations.

Direct Synthesis of Silicon Compounds
The development of industrial organosilicon chemistry, and thus the development of silicon chemistry, is partly related to the discovery of the direct process of organosilanes synthesis in the 1940s, which allowed the production of organosilanes and silicone polymers on a large scale, and resulted in the development of new technologies to produce organosilicon monomers and polymers. The direct synthesis process, also known as the Müller–Rochow process, is one of the best-known industrial processes for obtaining organosilicon compounds, and has been the basis of the silicone industry.

Plant Cellulose Nanofibre-Based Aerogels
Cellulose nanomaterials from plant fibre provide potential applications in biomedical. The biomedical application of nanocellulose isolated from plant fibre, which is a carbohydrate-based source, is very viable in the 21st century. The essential characteristics of plant fibre-based nanocellulose, which include its molecular, tensile and mechanicalproperties, as well as its biodegradability potential, have been widely explored for functional materials in the preparation of aerogel. Plant cellulose nano fibre (CNF)-based aerogels are novel functional materials that have attracted remarkable interest. In recent years, CNF aerogel has been extensively used in the biomedical field due to its biocompatibility, renewability and biodegradability. The effective surface area of CNFs influences broad applications in biological and medical studies such as sustainable antibiotic delivery for wound healing, the preparation of scaffolds for tissue cultures, the development of drug delivery systems, biosensing and an antimicrobial film for wound healing. Many researchers have a growing interest in using CNF-based aerogels in the mentioned applications. The application of cellulose-based materials is widely reported in the literature. However, only a few studies discuss the potential of cellulose nanofibre aerogel in detail. The potential applications of CNF aerogel include composites, organic–inorganic hybrids, gels, foams, aerogels/xerogels, coatings and nano-paper, bioactive and wound dressing materials and bioconversion.

PEDOT:PSS Layer and Perovskite Solar Cells
Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is the most successful conducting polymer, which has been widely used in displays, transistors, various sensors and photovoltaics (PVs). It has high optical  transparency in the visible light range and low-temperature processing condition, making it one of the most widely used polymer hole transport materials inverted perovskite solar cells (PSCs), because of its high optical transparency in the visible light range and low-temperature processing condition. However, the stability of PSCs based on pristine PEDOT:PSS is far from satisfactory, which is ascribed to the acidic and hygroscopic nature of PEDOT:PSS, and property differences between PEDOT:PSS and perovskite materials, such as conductivity, work function and surface morphology.

Carbonation of Concrete
As one of the major causes of concrete deterioration, the carbonation of concrete has been widely investigated over recent decades. In recent years, the effect of mechanical load on carbonation has started to attract more attention. The load-induced variations in crack pattern and pore structure have a significant influence on CO2 transport which determines the carbonation rate.
