Metal-Based Nanomaterials
Metal-based nanomaterials could be widely used in biomedical fields, as metal ions are essential in living organisms. Since the particle size of the virus particles ranges from tens to hundreds of nanometers, the surface activity of the metal material is enhanced after the metal is nanosized. It can be used in the inhibition of virus infection.

Chemistry and pharmacological study of Aspidosperma pyrifolium (Apocynaceae)
Aspidosperma pyrifolium Mart., popularly known as “pereiro-preto”, is a small tree that is widely distributed in Northeastern Brazil, more precisely in the Caatinga. Its wood is used in the manufacture of furniture, due to its excellent quality; in traditional medicine, the extract of its leaves and bark is used for its anti-inflammatory and analgesic properties. The study made it possible to isolate 15-methoxyaspidospermine and 15-methoxypyrifolidine, corroborating the results of pharmacological assays, which showed anti-inflammatory and analgesic potential, especially at 30 mg kg−1 (p < 0.001). Thus, the species was shown to be a promising source of active substances, with special attention paid to its toxicological potential.

Carica papaya Leaf Extract
Carica papaya (papaya) leaf extract has been used for a long time in a traditional medicine to treat fever in some infectious diseases such as dengue, malaria, and chikungunya. The development of science and technology has subsequently made it possible to provide evidence that this plant is not only beneficial as an informal medication, but also that it has scientifically proven pharmacological and toxicological activities, which have led to its formal usage in professional health care systems.

Applications of Magnetic Hydrogels
Magnetic hydrogels (MHGs) are a special class of hydrogel that contain at least one magnetic component in their composition. Generally, MNPs are dispersed in a polymer gel matrix to form MHGs. These hydrogels are special because they are prone to show fluctuations in their physical properties in the presence of an externally applied magnetic field.

Hydrogels Classification
Hydrogels are attractive biomaterials with favorable characteristics due to their water uptake capacity. However, hydrogel properties are determined by the cross-linking degree and nature, the tacticity, and the crystallinity of the polymer.

Surface Treatment in PDMS-Microfluidic Devices
Microfluidic lab-on-a-chip cell culture techniques have been gaining popularity by offering the possibility of reducing the amount of samples and reagents with greater control over the cellular microenvironment. Polydimethylsiloxane (PDMS) is the commonly used polymer for microfluidic cell culture devices because of the cheap and easy fabrication techniques, non-toxicity, biocompatibility, high gas permeability, and optical transparency.

Magnetic Guiding
Magnetic guidance is understood as a remote, untethered and contact-free control of the movements of an object via magnetic interactions. The movements should happen on arbitrary trajectories inside a container caused by an external device. The concept of remote magnetic guiding is developed from the underlying physics for bijective force generation over the inner volume of magnet systems. This concept can equally be implemented by electro- or permanent magnets.

Multifunctional Polymeric Nanogels for Biomedical Applications
Currently, research in nanoparticles as a drug delivery system has broadened to include their use as a delivery system for bioactive substances and a diagnostic or theranostic system. Nanogels, nanoparticles containing a high amount of water, have gained attention due to their advantages of colloidal stability, core-shell structure, and adjustable structural components. These advantages provide the potential to design and fabricate multifunctional nanosystems for various biomedical applications. Modified or functionalized polymers and some metals are components that markedly enhance the features of the nanogels, such as tunable amphiphilicity, biocompatibility, stimuli-responsiveness, or sensing moieties, leading to specificity, stability, and tracking abilities.

Copper-Coated Used Fuel Container
The Copper Coated Used Fuel Container is the main containment barrier in the engineered barrier system. The role of copper coated used fuel container is to provide containment for used CANDU (CANada Deuterium Uranium) fuel and any other fuel deemed acceptable for a deep geological repository in accordance with the Nuclear Fuel Waste Act (S.C. 2002, c.23) and Nuclear Waste Management Organization’s waste acceptance criteria.
