Using Fiber Bragg Grating Sensors to Quantify Temperature Non-Uniformities in Plasmonic Catalyst Beds under Illumination

Distinguishing between photothermal and non-thermal contributions is essential in plasmon catalysis. Use of a tailored optical temperature sensor based on fiber Bragg gratings enabled us to obtain an accurate temperature map of an illuminated plasmonic catalyst bed with high spatiotemporal resolution. Its importance for quantification of the...

Low temperature sunlight‐powered reduction of CO2 to CO using a plasmonic Au/TiO2 nanocatalyst

Sunlight-powered reduction of CO2to fuels and chemicals is apromising strategy to close the carbon loop and facilitate theenergy transition. In this research, we demonstrate that Aunanoparticles supported on TiO2are an efficient plasmoniccatalyst for the sunlight-powered reverse water-gas shift (rWGS)reaction. A maximum CO production rate of429...

Collective photothermal effect of Al2O3-supported spheroidal plasmonic Ru nanoparticle catalysts in the sunlight-powered Sabatier reaction

Sunlight-Fueled, Low-Temperature Ru-Catalyzed Conversion of CO2 and H2 to CH4 with a High Photon-to-Methane Efficiency

Methane, which has a high energy storage density and is safely stored and transported in our existing infrastructure, can be produced through conversion of the undesired energy carrier H2 with CO2. Methane production with standard transition-metal catalysts requires high-temperature activation (300−500 °C). Alternatively, semiconductor metal...

Security in NATO collective mission training - Problem analysis and solutions

We never fight alone, so we should train together! With missions being joint and combined, we also need to train that way. Given limited budgets and available resources, distributed simulation is rapidly becoming a necessity for collective mission training. However, due to the characteristics of mission simulations the protection of classified...

Multi-Level Security Cannot Realise NEC Objectives

Multi-Level Security (MLS) is often viewed as the holy grail of information security, especially in those environments where information of different classifications is being processed. In this paper we argue that MLS cannot facilitate the right balance between need-to-protect and duty-to-share as required for a Network Enabled Capability (NEC)...

Labelling: Security in Information Management and Sharing

Military communication infrastructures are often deployed as stand-alone information systems operating at the System High mode. Network-Enabled Capabilities (NEC) and combined military operations lead to new requirements for information management and sharing which current communication architectures cannot deliver. This paper informs...

Towards Multi-Level Security for NATO Collective Mission Training – a White Paper

Distributed simulation is rapidly becoming a necessity for collective mission training. With missions being joint and combined, we will never fight alone. Thus we need to train together, within and between nations. However, in any such scenario it is likely that some or all of the information may be classified at some level and need protection,...

A Secure NEC-enabling Architecture: Disentangling Infrastructure, Information and Security

The NATO Network-Enabled Capability (NNEC) study envisions effective and efficient cooperation among the coalition partners in missions. This requires information sharing and efficient deployment of IT assets. Current military communication infrastructures are mostly deployed as stand-alone networked information systems operating at the System...

IPv6 Monitoring in Nederland: De derde meting : TNO-White paper

Dit whitepaper beschrijft de derde meting in het kader van IPv6 monitoring in Nederland. Eerder zijn de Nulmeting2 en Tweede Meting3 gepubliceerd. In de tweede helft van 2011 zal nog een vierde meting gepubliceerd worden. Uit de vorige metingen is gebleken dat IPv6 bewustzijn toeneemt, maar dat het nog op weinig plekken daadwerkelijk is...

Old School Hacking Treft Smartphones: Hoe operators hun netwerk kunnen beveiligen

Smartphones en tablets zijn vatbaar voor allerhande virussen en mal-ware infecties. Meestal is het de taak van de gebruiker om zich daaryegen te beschermen. Hij moet pincodes instellen, firewalls opzetten en virussscanners installeren, Cybercriminaliteit is echter niet een probleem van de eindgebruiker alleen. Ook de operators hebber er een...

Security Shift in Future Network Architectures

In current practice military communication infrastructures are deployed as stand-alone networked information systems. Network-Enabled Capabilities (NEC) and combined military operations lead to new requirements which current communication architectures cannot deliver. This paper informs IT architects, information architects and security...
