Electron-Beam Damage Mechanisms and Strategies in MOFs
Metal–organic frameworks (MOFs), composed of metal nodes and inorganic linkers, are promising for a wide range of applications due to their unique periodic frameworks. Understanding structure–activity relationships can facilitate the development of new MOFs. Transmission electron microscopy (TEM) is a powerful technique to characterize the microstructures of MOFs at the atomic scale. In addition, it is possible to directly visualize the microstructural evolution of MOFs in real time under working conditions via in situ TEM setups. Although MOFs are sensitive to high-energy electron beams, much progress has been made due to the development of advanced TEM.

Morphological Characterization of Capsules
Encapsulation is a process in which a micron-sized particle of the main substance is coated and surrounded by a wall/carrier material that insulates and protects the contents from the external environment. The resulting encapsulation product is called a capsule or encapsulate.

MOS Gas Sensor for Lung Cancer Diagnosis
Lung cancer is the most prevalent severe illness in both sexes and all ages and the leading cause of cancer-related deaths globally. Late-stage diagnosis is the primary cause of its high mortality rate. Therefore, the management of lung cancer needs early-stage screening. Breath analysis is a non-invasive, low-cost, and user-friendly approach to diagnosing lung cancer. Among the various types of breath sensors, metal oxide semiconductor (MOS) gas sensors are preferred due to their high gas responses, fast response times, robustness, and lower price.

Hydrogel-Based Flexible Supercapacitors for Wearable Applications
Hydrogels are often known as three-dimensional networks of polymer chains capable of holding a large quantity of water while also being water insoluble. Research into “hydrogels” is currently a growing topic of scientific interest due to their diverse applications and eco-friendly properties.

Wire and Arc Additive Manufactured Materials Corrosion Behaviour
Wire and Arc Additive Manufacturing (WAAM) is a deposition rate process for the creation and/or repair of large structural metallic components. The non-equilibrium heating and cooling conditions associated with WAAM lead to the development of heterogenous microstructures. Although there is a large body of work focusing on the microstructure and mechanical properties of WAAM-fabricated components, assessment of the corrosion behaviour of alloys fabricated by WAAM is still in its infancy. Here, the body of knowledge associated with the corrosion behaviour of different WAAM-fabricated engineering alloys is presented and discussed. Future perspectives and potential research topics are also presented. This is the first work focusing on the corrosion of wire and arc additive manufactured materials.

Ultrafine-Grained Stainless Steels after Severe Plastic Deformation
Both mechanical properties and corrosion resistance of various stainless steels can be optimized owing to grain refinement decreasing the grain size down to hundreds of nanometers. The ultrafine-grained (UFG) microstructures can be obtained in ferritic and austenitic stainless steels by means of large strain deformation using severe plastic deformation (SPD) or conventional processing methods under conditions of cold to warm working. The UFG stainless steels are characterized by high strength. However, the strengthening by large strain deformation is accompanied by a substantial degradation of plasticity. Therefore, the UFG stainless steels are frequently subjected to recovery/recrystallization annealing to balance the strength and plasticity. The revealed relationships among a range of microstructural parameters open up a promising approach to clarify the mechanical behaviour of UFG stainless steels. Therefore, UFG stainless steels produced by large strain deformation have great potential for various applications as structural and functional materials.

Electroluminescence Devices Based on Self-Healable Hydrogels
Self-healing generally refers to a process of recovery after failures caused by mechanical pressures. The lifetime of a conventional electroluminescence (EL) device is restricted due to the damage that occurs when mechanical strain exceeds the resistance limit. Therefore, developments of EL devices focus on developing electrode materials that can recover after stress, so that the lifetime and reliability of the EL device improve. Such device construction requires self-healable materials. Hydrogel-based materials are perfect candidates for this type of application.
