Beyond Nanoporosity: A CO2‐Conditioned Glassy Matrix Contributes to the Brittle‐to‐Ductile Transition of Nanocellular Polyetherimide

Advanced Materials, EarlyView.
The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy matrix before foaming. This matrix contribution provides a new route to understand and optimize the brittle to ductile transition in nanocellular polymers.

Metastable Polymers for Circular 3D Printing

Advanced Materials, EarlyView.
3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Booster heat pumps and central heat pumps in district heating

Applied Energy, 2016
Abstract District heating (DH) enables the utilisation and distribution of heating from sources unfeasible for stand-alone applications and combined with cogeneration of heat and power (CHP), has been the cornerstone of Denmark’s realisation of a steady national primary energy supply over the last four decades.

A DEHUMIDIFYING HEAT PUMP FOR GREENHOUSES

Acta Horticulturae, 2012
In heated greenhouses, attempts have been made to produce potted plants while reducing the amount of energy used. In fact, improvements in greenhouse structure and equipment (double walls, etc.) have led to better insulation and tightness. However, this tightness induces microclimatic changes, especially on night time humidity levels.

Heat exchangers and the performance of heat pumps – Analysis of a heat pump database

Applied Thermal Engineering, 2011
Abstract Heat pumping is a highly energy-efficient technology that could help reduce energy and environmental problems. The efficiency of a heat pump greatly depends on the individual and integral performance of the components inside. In this study, heat pump performance is investigated with a special focus on heat exchangers.

Possibilities of heat pumps for heating homes

Electrical Engineering, 1944
Heat pumps are refrigerating systems in which the principal interest is in the heat given off by the condenser. A portion of this comes from the electric input to the compressor and the remainder from cooling an external source of heat, usually outdoor air.
