Minuscule pliers made of soft filaments added to the ends of optical fibres can be controlled with visible light, and could be used to grip objects tens of micrometres in size, such as some individual cells.

In this Special Issue, we welcome contributions which facilitate the search for win-win solutions where cost-efficient commercial urban transport can be successfully achieved with the use of electric vehicles. Suitable submissions include the adaptation of existing distribution and service logistics systems with the inclusion of electric vehicles (e.g., within city logistics concepts), fleet analysis and routing tools, lifecycle and total cost of ownership (TCO) estimations, cost and environmental impact assessment, etc. Furthermore, we welcome successful case studies demonstrating the applicability of electric vehicles for urban freight transport and logistics.
