RF Sputtering onto Liquid Substrates for a Dry Single-Step Preparation of Nanofluids

Size-controlled Cu and Au nanoparticles were deposited onto low vapor pressure liquid by RF magnetron sputtering. The deposition protocol was optimized to gain good control over plasma parameters and host liquid features to tune the physical properties of the resulting nanofluid. This work aims at developing a green and one-step approach in the synthesis of ultrapure catalyst nanoparticles.

Role of Oxygen Plasma Treatments in Cu/CNT Nanohybrids Synthesis by RF Sputtering

This study investigated the effect of oxygen plasma as pre- and post-treatment in metal NPs deposition on CNTs by RF sputtering. Oxygen plasma treatments allowed the modulation of surface functional groups which favor the loading of the metal NPs and help tuning the colloidal stability of the obtained nanohybrids. These nanohybrids will be employed for energy catalyst applications.

Enhancing Usability in E-Voting Systems: Balancing Security and Human Factors with the HC3 Framework

A smashed glass cannot be full: Generation of Commonsense Explanations through Prompt-based Few-shot Learning

We assume that providing explanations is a process to elicit implicit knowledge in human communication, and propose a general methodology to generate commonsense explanations from pairs of semantically related sentences. We take advantage of both prompting applied to large, encoder-decoder pre-trained language models, and few-shot learning techniques, such as pattern-exploiting training. Experiments run on the e-SNLI dataset show that the proposed method achieves state-of-the-art results on t...

Turn-by-turn measurements of the energy spread at negative momentum compaction factor at KARA

The Karlsruhe Research Accelerator (KARA), the storage ring at KIT, allows short electron bunch operation with positive as well as negative momentum compaction factor. For both cases, the beam dynamics are studied. Using a line array camera KALYPSO (KArlsruhe Linear arraY detector for MHz rePetition rate SpectrOscopy), based on TI-LGAD, the horizontal intensity distribution of the emitted visible part of the synchrotron radiation is measured at a 5-degree port of a bending magnet on a turn-by...
