Cellulose Nanocrystal and Water-Soluble Cellulose Derivative Based Electromechanical Bending Actuators
(MDPI, 2020-05-15)
This study reports a versatile method for the development of cellulose nanocrystals (CNCs) and water-soluble cellulose derivatives (methyl cellulose (MC), hydroxypropyl cellulose (HPC), and sodium carboxymethyl cellulose ...
Identification of Key Performance Indicators in Project-Based Organisations through the Lean Approach
(MDPI, 2020-07-24)
For the time being, companies and organisations are being forced to compete in utterly complex and globalised environments, facing massive natural, economic, and technological challenges on a daily basis. Addressing these ...
Influence of Process Parameters in Graphene Oxide Obtention on the Properties of Mechanically Strong Alginate Nanocomposites
(MDPI, 2020-02-28)
Sodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve ...
An Adaptable Train-to-Ground Communication Architecture Based on the 5G Technological Enabler SDN
(MDPI, 2019-06-12)
Railway communications are closely impacted by the evolution and availability of new wireless communication technologies. Traditionally, the critical nature of railway services, the long lifecycle of rolling stock, and ...
The cross layer RMPA handover: a reliable mobility pattern aware handover strategy for broadband wireless communication in a high-speed railway domain
(Springer, 2012)
Enhancing the handover process in broadband wireless communication deployment has traditionally motivated many research initiatives. In a high-speed railway domain, the challenge is even greater. Owing to the long distances ...
Iridescent Cellulose Nanocrystal Films: the Link Between Structural Colour and Bragg's Law
(Iop Publishing, 2018-04-30)
Structural colour is a phenomenon found in nature, which provides plants and animals with vibrant optical properties. The production of this colour is based on the interaction of incident light with the hierarchical ...
Towards Circular Economy: Different Strategies for Polyurethane Waste Recycling and the Obtaining of New Products
(MDPI, 2018-11-22)
As a consequence of the high production and simultaneous consumption of polyurethanes
(PU) a great volume of PU waste is landfilled. In this scenario, suitable and efficient routes for PU
waste recycling have been searched ...
Lignocellulosic Biomass as a Source of Raw Materials for the Synthesis of Polyurethanes
(MDPI, 2018-11-06)
Precursors have been satisfactorily synthesized from lignocellulosic biomass for later use in the synthesis of polyurethanes resulting in competitive final properties with those of petroleum derived polyurethanes
How Do People Move Around? National Data on Transport Modal Shares for 131 Countries
(MDPI, 2020-06-18)
The COVID-19 pandemic has brought global mobility into the spotlight, with well over 100 countries having instituted either a full or partial lockdown by April 2020. Reduced mobility, whilst causing social and economic ...
European Cities in the Energy Transition: A Preliminary Analysis of 27 Cities
(MDPI, 2020-03-12)
Nowadays, there is a wide scientific consensus about the unsustainability of the current energy system and at the same time, social awareness about climate change and the IPCC’s goals is increasing in Europe. Amongst ...
