AbstractThis review presents a brief overview of the electrical and gas-sensor properties of polyaniline (PANI) and graphene-based nanocomposites, their application as gas detection materials, and their underlying sensing mechanisms. Several studies have shown that graphene-based PANI gas sensors perform remarkably well at ambient temperatures, are energy efficient, and are inexpensive. The electrical and gas sensing properties of PANI/graphene nanocomposites offer improved responsiveness, durability, and other detection capabilities in sensor-based devices at room temperature. Moreover, the electrical conductivity and gas sensor properties may be controlled by the synthesis methods and the form and type of graphene. This review provides a new framework for the development of new nanomaterials based on PANI/graphene, which will advance their development and industrialization in the environment.Keywords: PANI/graphene nanocompositesgrapheneelectrical propertiesgas sensing properties Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe authors extend their appreciation to the Deanship of Scientific Research at King Khalid University (KKU) for funding this research through the Research Group Program Under the Grant Number: (R.G.P.2/588/44).

Special emphasis is placed on materials prepared by modern techniques, including microwave-assisted synthesis, ultrasound-assisted and sonochemical methods, synthesis employing metal-organic framework precursors, and electrospinning methods. The effects of intrinsic magnetism and external magnetic fields on the efficiency of ferrites in selected energy applications are also highlighted.

AbstractNa-ion batteries (SIBs) are a promising replacement for lithium-ion batteries (LIBs) for low-cost and large-scale energy storage systems in the forthcoming years after additional in-depth examination and investigation. A significant part of the development of innovative anode materials and their in-depth understanding has come through simulations. Ab initio simulations based on density functional theory (DFT) have been proven to be a reliable, efficient, and cost-effective way to design new anode materials for SIBs. As a result of the identification of graphene, researchers and scientists were influenced to create new two-dimensional (2D) materials. On account of their distinctive physical and chemical properties, the broad expanse of surface, innovative electronic features, and charging ability of 2D materials attract much attention. Many of these characteristics are significant prerequisites for using anodes in batteries. Herein, based on recent research progress, we have reviewed the structures and electrochemical properties of 2D materials as anode for Na-ion batteries from a theoretical perspective. The effective methodologies for high-performance anode materials are provided based on the substantial literature and theoretical studies. Added to that, we have also explored the various techniques such as heterostructure, doping, defect- and strain-engineering of 2D materials for the improvement of the performance of these materials as anodes for SIBs.Keywords: 2D Materialsdensity functional theoryenergy storagespecific capacityanode materials AcknowledgementsNV thanks the CSIR for providing financial support in the form of a junior research fellowship (JRF).

Among the alloy systems for the fabrication of metallic components using additive manufacturing (AM), steels as a broad family of alloys attract significant attention owing to their established mechanical and corrosion properties under various loading and environmental conditions. In an erosive/corrosive environment, the possible failure mechanisms necessitate consideration in materials selection and design. Although functional alloying elements are deliberately added to steels to improve corrosion resistance, the crucial role of initial microstructure and post-process heat treatments are equally critical and cannot be neglected. Specifically, the proper selection and optimization of AM process parameters are essential steps in minimizing microstructural defects. This comprehensive review provides a consolidated treatise of powder atomization techniques, AM process parameter control, rapid solidification principles, their roles on the as-built microstructure. The role of different phases and microstructures formed during post-process heat treatments, and corrosion behavior of various grades of AM steels are also presented. The review presents the interplay between process-microstructure-corrosion properties of the AM steels through the entire fabrication process - from powder feedstock to final AM product exposed to harsh environments. In the first section of this review paper, the authors comprehensively explain the important factors, which affect the processability and quality of AM steel components. In the second section, the authors focus on the microstructure of both as-printed and heat-treated AM steel products, the parameters which determine variations of the microstructure, the effect of microstructural features such as the grain size and the dendrite arm spacing on the mechanical properties, and the detrimental effect of inclusions embedded into the matrix. Finally, the third part of the paper is a comprehensive review of the corrosion of different types of stainless steels (316 L austenitic stainless steel, 420 martensitic stainless steel, martensitic precipitation-hardened stainless steels of 15-5 PH, 17-4 PH, and Corrax) fabricated by AM techniques.

AbstractMany thin film applications are based on oxides. The optimization of the oxide properties is an on-going process and requires a deep understanding of the deposition process. A typical feature of reactive (magnetron) sputter deposition is the presence of negative oxygen ions. Two groups of ions can be identified based on their energy. Low energy ions are generated in the bulk of the discharge. The high energy ions are emitted from the oxide or oxidized target surface. As these ions are generated at the cathode, they are accelerated by the electric field toward the growing film. Depending on the discharge voltage and the powering method, their energy is typically several tenths to hundreds electron volt. As such the ions can have a strong impact on the film properties. In the case of magnetron sputtering, this will lead to inhomogenous film properties over the substrate facing the locally eroded target. Due to their high energy, the trajectory of negative ions can be easily predicted which has led to several strategies to avoid negative ion bombardment such as facing target sputtering and off-axis sputtering. This paper reviews several facets of the production, the measurements and the impact on the film properties of negative ions during reactive sputtering. Despite the many illustrative studies on the impact of negative oxygen ions, quantification is often lacking as the negative ion yield is only known for a few oxides. The compilation of several literature sources allows the discussed trends to be placed in a quantitative framework.Keywords: Negative ion yieldmagnetron sputteringion assisted deposition AcknowledgementsThis work is dedicated to two researchers who have passed away recently and had a major impact on the scientific career of the author. The first researcher is Professor Johan (Jo) Haemers, a member of the same department, who assisted the research of the author in the development of special measuring set-ups, and in long discussions on science and other important things in life.
