7. Nanomaterials science and technologyhave sparked a lot of interest and anticipation in recent years. Nanostructures are also suitable for computer simulation and modelling because their scaleis small enough to allow for a high level of rigour in treatment. In nanomaterials computations, the spatial scaling ranges from 1 to 1 mm, and the temporal scaling ranges from 1 fs to 1 s, with the precision limit exceeding 1 kcalmol-1. Contd... Nanomaterials

8. Two examples of recent successes and paradigm changes in this area are STM images of quantum dots (e.g., a germanium pyramid on a silicon surface) and the quantum corral of 48 Fe atoms arranged in a circle of 7.3 nm radius.[1]. However, tunable Superhydrophobicity from 3D Hierarchically NanoWrinkled MicroPyramidal Architectures was recently reported by Weixin Zhang andcollaborators. Contd...

9. With a touch angle of 172° and a sliding angle of 5° in a steady “Lotus” state, excellent Superhydrophobicity is achieved due to multiscalestructures. Furthermore, the wear resistance and stability measurements indicate that the material will outperform in simulated extreme real-world applications[2]. Contd...

11. Stabilising a consistent and renewable electricity supply to satisfy the world’s rising energydemands is one of the biggest problems of the twenty-first century. With the introduction of renewable energies, there is a new market for energy storagefacilities. Perovskite oxides are valuable functional materials with outstanding physical and chemical properties used in ferroelectric, piezoelectric, dielectric, energy conversion and storage, and other applications. Contd... Energymaterials

12. Oxygen evolution reaction, oxygen reduction reaction, electrochemical water splitting, metal-air batteries, solid-state batteries, oxygen separation membrane, and solid oxide fuel cells are some of the newer uses of perovskiteoxides. While various behaviour descriptors for perovskite oxides have been published, such as the number of d electrons, Eg occupancy, bulk-forming energy, metal-oxygen covalency, and the location of the O–p band gravity core, there is still a need for the world and feasible reactivitydescriptor. Contd...

13. Furthermore, high-throughput DFTcalculations,machine learning, and artificial intelligence helpspeed up exploring newmaterials. Perovskite oxides’ drawbacks include low electronic conductivity at room temperature and instability in acidicenvironments. Adding a certain volume of metals or creating composites with strong electronic conductors, such as carbon nanotubes, graphene, or Mxenes, is one efficient way to increase electronic conductivity. Nanostructured materials with higher surface area and more open reactive sites usually perform better than bulkmaterials Contd...

Even though tissue engineering and regenerative Biomaterials medicine have long dominated the field of in biomaterials, new research shows promise offering transformative solutions to viral outbreaks [4]. Clinical perspectives are exchanged to identify current healthcare needs better than biomaterials technologies canaddress. Contd...

15. The most popular screening patient samples for current SARS-CoV-2 infection is nucleic acid testing via reverse transcription-polymerase chain reaction(RT-PCR). Nanostructures may be built to replicate living cells in a different nanomaterials-centred approach. Nanodecoys constructed from cell membrane-derived materials are used to trap and sequesterviruses. Biomaterials provide several possibilities for overcoming the shortcomings of current clinical techniques (Figure1). Contd...

17. Nanodecoys engineered to capture and sequester virus may be inserted directly into the bloodstream (topleft). In contrast, drug-loaded nanoparticles can be formulated as inhalants to administer medications to lung tissue locally (topright). Extracorporeal blood therapies may replenish O2 (bottom right), modulate immune signalling by removing or supplementing proinflammatory cytokines, or eliminate virus particles directly from the bloodstream (bottom left)[4] Contd...

18. Polymersandplastics Plasticisers have long been recognised for producing lightweight plastics in various industries, including the automobile industry, medical devices, and consumergoods. Because of the constantly evolving spectrum of bio-based and biodegradable polymers and rising interest in investing in the bioplastics market, global bioplastics output capacities are difficult to predict and are typically based onprediction. Contd...

19. Natural polymers such as cellulose derivatives, thermoplastic starch (TPS), and their blends have the largest processing potential, as these components are increasingly replacing plastics in the lightweight film packagingindustry. Bio monomers-derived glucose fermentation or lignin fermentation have also been used to produce commonly used commodity polymers, including polyethene terephthalate, polyamide, and polypropylene, including polyethene terephthalate, polyamide, and polypropylene for the revival of Bio-PET, Bio-PA, and Bio-PP,respectively. Using unaccounted biomass as a valuable resource and rationally engineering bioplastics to impart optimal versatility and recyclability would provide a sustainable bioplastics production value chain[5]. Contd...

21. Metalsandalloys Stainless steel, titanium and its alloys, cobalt alloys, and other metals and alloys have all been used clinically as implantcomponents. Still, contamination or inflammation caused by the implant is also one of the leading causes of implantationfailure. Antibacterial metals and alloys have recently gained popularity due to their long- term antibacterial stability, strong mechanical properties, andbiocompatibility. Contd...

24. Ceramics Ceramic-based energy storage materials have significant benefits over polymer energy storage materials, such as outstanding thermal stability, long life span, and cycle time. Dielectric capacitors, which have the fastest charging/discharging rate and the highest power density for existing energy storage devices such as supercapacitors, batteries, and electrolytic capacitors, are allowing electric energydevices. Contd...

25. Lead zirconate titanate (PZT) is a common piezoelectric material that enables the synthesis of many materials with a broad range of properties due to the formulation of solid solutions over a wide range of Zr: Ti ratios. Also, this system accommodates a wide range of dopants for modification of crystalstructure. This method also supports a wide variety of dopants for crystal structurealteration. Because of its versatility, PZT has become very popular with users and researchers all over theworld. Some lead-free piezo material structures have been investigated, including BNT, BKT, KNN, and BZT-BCT. However, the advancement of lead-free piezo devices and their success with PZT devices is still in the earlystages.

27. It is critical for commercialising effective oxygen electrocatalysts for electrochemical energy storage and conversiontechnologies. A multidisciplinary methodology involving conventional electrochemistry, experimental solid-state chemistry and physics, advanced characterisation, and multiscale computational modelling will be needed for future advances in this excitingarea. To the environmental risk of potential pandemics, masks made of biodegradable materials or used for several purposes must bedesigned. Contd...

28. Cells and tissues are unaffected by antibacterial stainless steel, antibacterial titanium alloys, and antibacterial cobaltalloys. Surface biomodification to increase or enhance cell response is also needed, resulting in decreased antibacterialactivity. As a result, the choice of surface biomodification and its effect on cell reaction and antibacterial activity should be thoroughlyinvestigated. Contd...

29. Even though many antibacterial pathways have been thoroughly explored so far, the antibacterial process remains amystery. As a result, the production and preparation of antibacterial metal alloys are also heavily reliant on element alloying, including the appropriate Cu or Agelement.
