Selection and Optimal Use of Nanoporous Materials for Adsorption Energy Technologies

Due to the large waste of heat in the power and industrial sectors, our use of energy is inefficient. Moreover, it relies on rapidly depleting and greenhouse-gas-emitting sources such as fossil fuels. While the scarcity of energy resources is a relevant so ...

Oxidation of pyrite (FeS2) and troilite (FeS) impurities in kaolinitic clays after calcination

Karen Scrivener, Franco Alberto Zunino Sommariva

Valorisation of locally available clays for producing blended cements is crucial for a widespread adoption of sustainable binders incorporating these materials. In some places, clays can be intermixed with small amounts of iron sulfides, which could eventu ...

Design-to-Fabrication Workflow for Raw-Sawn-Timber using Joinery Solver

Petras Vestartas

Currently, the Swiss timber industry in mountain areas largely exports unprocessed lumber and imports finished timber products due to the lack of digital tools. By using new digital design-to-production workflows, it is possible to investigate new building ...

Removal of trace organic contaminants from wastewater by superfine powdered activated carbon (SPAC) is neither affected by SPAC dispersal nor coagulation

Tamar Kohn, Florence Bonvin, Loïc Decrey

Powdered activated carbon (PAC) is increasingly used as tertiary treatment for the removal of trace organic contaminants (TrOCs) from wastewater (WW). To enhance the sorption kinetics and capacity, the PAC particles can be milled down to super fine powdere ...

Biomechanical Properties and Resistance to Uprooting of Laboratory‐Scale Wood Logs

Paolo Perona

Wood dynamics affects riparian ecosystem functioning and river morphology. The spatial and temporal dynamics of wood pieces in river corridors, in particular of deposited rejuvenated wood logs, depend on their biomechanical properties and resistance to upr ...

Laser Scanning with Industrial Robot Arm for Raw-wood Fabrication

Yves Weinand, Petras Vestartas

This paper presents an integrated raw-wood fabrication workflow using an industrial robot arm and a laser scanner. The research is situated in a Swiss mountain forestry context where timber in its natural form could be applied locally without relying on la ...

Biomass burning aerosol as a modulator of the droplet number in the southeast Atlantic region

Athanasios Nenes

The southeastern Atlantic (SEA) and its associated cloud deck, off the west coast of central Africa, is an area where aerosol–cloud interactions can have a strong radiative impact. Seasonally, extensive biomass burning (BB) aerosol plumes from southern Afr ...

CS2 Reductive Coupling to Acetylenedithiolate by a Dinuclear Ytterbium(II) Complex

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez, Davide Toniolo

The activation of CS2 is of interest in a broad range of fields and more particularly in the context of creating new C‐C bonds. The reaction of the dinuclear ytterbium(II) complex [Yb2L4], 1, (L = (OtBu)3SiO‐) with carbon disulphide led to the isolation of ...

Design and demonstration of a prototype 1.5 kWth hybrid solar/autothermal steam gasifier

Sophia Haussener, Iacopo Guscetti

A 1.5 kWth hybrid solar/autothermal steam gasifier was designed and tested for continuously producing synthesis gas. Time-averaged responses to a series of inlet flow conditions were examined in a high-flux solar simulator. The gasifier consisted of a SiC ...
