Recent progress in metal-organic frameworks (MOFs) for CO2 capture at different pressures

2022

Global climate change ensued by the rise in atmospheric CO2 levels is one of the greatest challenges our planet is facing today. This worldwide distress demands technologies that can contribute to our society toward “negative carbon emissions”. Carbon capture and storage (CCS) technologies are in in important role for capturing CO2 from existing emission sources, such as industrial and energy production point sources, before new more prominent modifications to the energy infrastructure can be implemented. Recently, alongside point source capture, direct air capture (DAC) processes have emerged as highly sought-after technologies that are able to capture CO2 from the ambient air. Alongside t…

‘The best guess for the future?’ Teachers’ adaptation to open and flexible learning environments in Finland

2021

Finnish education has recently experienced reforms with respect to guidelines forming the curriculum framework for basic education and school architecture. Since 2016, all new schools incorporate open and flexible design, at least to some extent. The more open school design challenges the conventional organisation of space and pre-defined structures and interaction practices. This study investigates how teachers both adapt and are affected by new demands for pedagogy, team teaching and teacher-student relationships. Interview data of 21 teachers of six modern schools are reviewed through thematic analysis. The new school layouts provided some incongruence with the teachers’ aims and their p…

Co-designing a pedagogical framework and principles for a hybrid STEM learning environment design

2022

AbstractThe importance of engaging and effective learning environments for science, technology, engineering and mathematics (STEM) has been internationally recognised. However, no comprehensive pedagogical frameworks exist that support STEM learning environment design. In this study, a pedagogical framework and principles for STEM learning environment design were created based on participatory focus groups involving 10–18-year-old students, teachers, school directors, parents, university students and STEM professionals. Representatives of key stakeholder groups in Belarus, Finland, Germany, Greece and Spain (total n = 132) were invited to focus group discussions in which their wishes relate…

INSTITUTIONAL PROBLEMS OF PIG CARCASS CLASSIFICATION SECTOR IN ROMANIA

2015

The paper deals with the institutional problems faced by animal carcass classifying operators while implementing the SEUROP classification system in Romania. The research was performed in March 2015 by means of in-depth interviews with different economical operators in the pig-carcass classification sector. The main findings that need solutions in the next future are the following: still poor understanding of the benefits of the carcass classification activity by some direct beneficiaries, the need for a consolidation in current regulation, the need for a methodological framework for the uniform application of the law and a few external factors that can not be controlled by carcasses classi…

Selective Laser Sintering of Metal-Organic Frameworks: Production of Highly Porous Filters by 3D Printing onto a Polymeric Matrix.

2019

Metal‐organic frameworks (MOFs) have raised a lot of interest, especially as adsorbing materials, because of their unique and well‐defined pore structures. One of the main challenges in the utilization of MOFs is their crystalline and powdery nature, which makes their use inconvenient in practice. Three‐dimensional printing has been suggested as a potential solution to overcome this problem. We used selective laser sintering (SLS) to print highly porous flow‐through filters containing the MOF copper(II) benzene‐1,3,5‐tricarboxylate (HKUST‐1). These filters were printed simply by mixing HKUST‐1 with an easily printable nylon‐12 polymer matrix. By using the SLS, powdery particles were fused t…

Inside Cover: Hydrogen-Bonded Open-Framework with Pyridyl-Decorated Channels: Straightforward Preparation and Insight into Its Affinity for Acidic Mo…

2017

International audience; A hydrogen-bonded open framework with pores decorated by pyridyl groups was constructed by off-charge-stoichiometry assembly of protonated tetrakis(4-pyridyloxymethyl)methane and [Al(oxalate)(3)](3-), which are the H-bond donor and acceptor of ionic H-bond interactions, respectively. This supramolecular porous architecture (SPA-2) has 1nm-large pores interconnected in 3D with large solvent-accessible void (53%). It demonstrated remarkable affinity for acidic organic molecules in solution, which was investigated by means of various carboxylic acids including larger drug molecules. Competing sorption between acetic acid and its halogenated homologues evidenced good sel…

Sponge‐Like Behaviour in Isoreticular Cu(Gly‐His‐X) Peptide‐Based Porous Materials

2015

We report two isoreticular 3D peptide-based porous frameworks formed by coordination of the tripeptides Gly-L-His-Gly and Gly-L-His-L-Lys to Cu(II) which display sponge-like behaviour. These porous materials undergo structural collapse upon evacuation that can be reversed by exposure to water vapour, which permits recovery of the original open channel structure. This is further confirmed by sorption studies that reveal that both solids exhibit selective sorption of H2 O while CO2 adsorption does not result in recovery of the original structures. We also show how the pendant aliphatic amine chains, present in the framework from the introduction of the lysine amino acid in the peptidic backbo…
