TL;DR: Direct writing (DW) is a family of flexible multi-length scale processes for the deposition of functional materials to form simple linear or complex conformal structures on a substrate.
Abstract: Direct writing (DW), also known as digital writing or digital printing, is a family of flexible multi-length scale processes for the deposition of functional materials to form simple linear or complex conformal structures on a substrate. This paper provides an overview of key DW technologies and their process characteristics under a unified classification system. In DW, a variety of mechanisms and energy modes such as inkjet, laser, mechanical pressure and tips are used to create material transfer to produce features from the nm to the mm range. This new group of additive on-demand processes complements existing manufacturing methods especially in product miniaturization and geometrical footprint reduction due to its conformal writing capability. The range of materials is exceptionally wide, ranging from metallics, ceramics, dielectrics and polymers to biomaterials. The thickness of the layer ranges from a monolayer of molecules to hundreds of micrometres. As DW is a scalable process, it is capable of high-throughput volume production, especially in microelectronics. Industrial applications have been expanding and numerous niche examples are given to illustrate meso-, micro- and nano-scale applications. Finally, challenges for its future development are also discussed.

TL;DR: In this paper, a theoretical analysis for the erosion of metals by spheres at normal incidence is presented, which employs a criterion of critical plastic strain to determine when material will be removed, and velocity exponents of 3 for erosion and −2 for the mass of spherical particles which must hit the surface before material is removed.

TL;DR: In this paper, the authors describe the deposition methods, deposition mechanisms, characterisation methods, electronic structure, gap states, defects, doping, luminescence, field emission, mechanical properties and some applications of diamond-like carbon.
Abstract: Diamond-like carbon (DLC) is a metastable form of amorphous carbon with significant sp3 bonding. DLC is a semiconductor with a high mechanical hardness, chemical inertness, and optical transparency. This review will describe the deposition methods, deposition mechanisms, characterisation methods, electronic structure, gap states, defects, doping, luminescence, field emission, mechanical properties and some applications of DLCs. The films have widespread applications as protective coatings in areas, such as magnetic storage disks, optical windows and micro-electromechanical devices (MEMs).

TL;DR: In this paper, a review of recent advances in understanding the mechanical behavior of metallic glasses, with particular emphasis on the deformation and fracture mechanisms, is presented, where the role of glass structure on mechanical properties, and conversely, the effect of deformation upon glass structure, are also described.

TL;DR: An overview of the key aspects of graphene and related materials, ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries are provided.
Abstract: We present the science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts and benefits reaching into most areas of society. This roadmap was developed within the framework of the European Graphene Flagship and outlines the main targets and research areas as best understood at the start of this ambitious project. We provide an overview of the key aspects of graphene and related materials (GRMs), ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries. We also define an extensive list of acronyms in an effort to standardize the nomenclature in this emerging field.

TL;DR: It is found that the ratio between the D and G peak intensities, for a given defect density, strongly depends on the laser excitation energy, and a simple equation for the determination of the point defect density in graphene via Raman spectroscopy is presented.
Abstract: We present a Raman study of Ar(+)-bombarded graphene samples with increasing ion doses. This allows us to have a controlled, increasing, amount of defects. We find that the ratio between the D and G peak intensities for a given defect density strongly depends on the laser excitation energy. We quantify this effect and present a simple equation for the determination of the point defect density in graphene via Raman spectroscopy for any visible excitation energy. We note that, for all excitations, the D to G intensity ratio reaches a maximum for an inter-defect distance ~3nm. Thus, a given ratio could correspond to two different defect densities, above or below the maximum. The analysis of the G peak width and its dispersion with excitation energy solves this ambiguity.
