Diffusion-Controlled Electrocrystallization Process
Electrocrystallization is a complicated multistep chain reaction involving the diffusion and mass transfer of ions in solution, the removal of solvation shells, electron transfer, the formation of surface adsorbed atoms, the clustering of adsorbed atoms, the generation of crystal nucleus, or embedding into existing lattice. A short historical background to study the nucleation and growth by diffusion-controlled electrocrystallization is provided.

Digital and Smart Cities
Mobility is notoriously a key aspect of our modern economy and humans' way of life. In an edge situation such as the current coronavirus pandemic, transportation is one of the first affected mechanisms of a city. In our paper, we highlight the potential of operations research and computational intelligence tools for cities' services. The contributions involves aspects of optimization, internet-of-thing and internet-of-value (brought with concepts of Blockchain). When we sum up all these tools, it becomes possible to envision the potential that emerging software and systems can bring to society, associated with the wave of innovation surroundings the smart cities.

Digital Applications in Energy Sector
Digitalization is a transformation process which has already affected many parts of industry and society and is expected to yet increase its transformative speed and impact. In the energy sector, many digital applications have already been implemented. However, a more drastic change is expected during the next decades. Good understanding of which digital applications are possible and what are the associated benefits as well as risks from the different perspectives of the impacted stakeholders is of high importance. On the one hand, it is the basis for a broad societal and political discussion about general targets and guidelines of digitalization. On the other hand, it is an important piece of information for companies in order to develop and sustainably implement digital applications. This entry provides a structured overview of potential digital applications in the German energy (electricity) sector on the basis of a literature review.

Digital Circular Business Models
The concept of circular economy (CE) is receiving increasing attention worldwide as a way to overcome the issues of the current production and consumption model. It requires companies to rethink their supply chains and business models (BM). The CE is a regenerative economic system that necessitates a paradigm shift to replace the end of life (EoL) concept with reducing, alternatively reusing, recycling, and recovering materials throughout the supply chain, with the aim of promoting value maintenance and sustainable development, creating environmental quality, economic development, and social equity, to the benefit of current and future generations.

Digital Collaboration in Mixed-Use Housing Developments
Mixed-use development—with a diverse mix of residential, retail, commercial, social, and entertainment spaces all in one structure—has been recognised as an optimal solution to numerous urban challenges, including social, economic, and environmental ones. Such multifaceted programs can promote social equity and inclusiveness by offering a variety of housing options to people with a wide range of economic abilities. These potential social benefits of bringing a diverse range of amenities and services together can lead to enhanced safety and increased movement independence, especially for socially disadvantaged groups.

Digital Enhanced Cordless Telecommunications
Digital Enhanced Cordless Telecommunications (Digital European Cordless Telecommunications), usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the universal standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2. Beyond Europe, it has been adopted by Australia , and most countries in Asia and South America. North American adoption was delayed by United States radio frequency regulations. This forced development of a variation of DECT, called DECT 6.0, using a slightly different frequency range which makes these units incompatible with systems intended for use in other areas, even from the same manufacturer. DECT has almost universally replaced other standards in most countries where it is used, with the exception of North America. DECT was originally intended for fast roaming between networked base stations and the first DECT product was Net3 wireless LAN. However, its most popular application is single-cell cordless phones connected to traditional analog telephone, primarily in home and small office systems, though gateways with multi-cell DECT and/or DECT repeaters are also available in many private branch exchange (PBX) systems for medium and large businesses produced by Panasonic, Mitel, Gigaset, Snom, BT Business, Spectralink, and RTX Telecom. DECT can also be used for purposes other than cordless phones, such as baby monitors and industrial sensors. The ULE Alliance's DECT ULE and its HAN FUN protocol are variants tailored for home security, automation, and the internet of things (IoT). The DECT standard includes the generic access profile (GAP), a common interoperability profile for simple telephone capabilities, which most manufacturers implement. GAP-conformance enables DECT handsets and bases from different manufacturers to interoperate at the most basic level of functionality, that of making and receiving calls. New Generation DECT (NG-DECT) standard, marketed as CAT-iq by the DECT Forum, provides a common set of advanced capabilities for handsets and base stations. CAT-iq allows interchangeability across IP-DECT base stations and handsets from different manufacturers, while maintaining backward-compatibility with GAP equipment. It also requires mandatory support for wideband audio.

Digital Hydraulic Technology
The digital hydraulic technology as a system which controls a discrete fluid with a modulated, discrete, digital signal directly to realize active and intelligent control of the system output. The hydraulic components with such technical characteristics can be defined as digital hydraulic components. The system composed by digital hydraulic components can also be defined as digital hydraulic system. What is more, the essential feature of digital hydraulic technology is intelligent control; technology which can only realize on/off control cannot be classified as digital hydraulic technology.

Digital Image Correlation
Digital Image Correlation (DIC) is a non-invasive imaging technique that has been used in a significant number of research fields to measure the strain fields across the surface of a body. This entry gives a basic overview of how the DIC method came to be, both in two and three dimensions and some information about the more recent development of DIC in the X-ray spectrum.

Digital Image Correlation Methodology Evolution
Reliable assessment and prediction of the technical condition of reinforced concrete structures require accurate data of the stress–strain state of the structure at all stages of loading. The most appropriate technique to obtain such information is digital image correlation. Digital image correlation is a class of contactless methods which includes the following stages: obtaining an image from a studied physical object, saving it in digital form, and further analysis in order to obtain the necessary information about the stress–strain state of the structure.
