Fully Bio‐Based Epoxy Thermoset Based on Epoxidized Linseed Oil and Tannic Acid

open access: yesMacromolecular Materials and Engineering, Volume 307, Issue 12, December 2022., 2022
By using epoxidized linseed oil and tannic acid to produce a bio‐based thermoset, this work pursues the approach of replacing hazardous and petrochemical‐derived materials with nontoxic bio‐based materials while preserving the efficacy of function. Thus, good thermal‐ and mechanical properties such as a flexural modulus of 2986 MPa, Tg of 147 °C, or ...

Monitoring Nanostructural Dynamics During the Electrochemical Growth of Metal Hydroxide Thin Films by in‐situ Small‐Angle X‐Ray Scattering

open access: yesChemistry–Methods, EarlyView.
We present a custom‐built electrochemical flow cell for in‐house real‐time small‐angle X‐ray scattering (SAXS) experiments to monitor the electrocrystallization of nanoscale Co(OH)2 platelets tracking their growth from 7.8 nm to 15.7 nm thickness. Citrate ligands initially stabilize spherical structures, transitioning to platelet morphologies as the ...

Spotting LLMs With Binoculars: Zero-Shot Detection of Machine-Generated Text [PDF]

open access: yesarXiv
Detecting text generated by modern large language models is thought to be hard, as both LLMs and humans can exhibit a wide range of complex behaviors. However, we find that a score based on contrasting two closely related language models is highly accurate at separating human-generated and machine-generated text.

Supplementing Single‐Arm Trials with External Control Arms—Evaluation of German Real‐World Data

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
As single‐arm trials (SATs) are increasingly used in pharmaceutical research, the validity of such study designs needs to be critically assessed. We characterize the feasibility of supplementing SATs with real‐world data (RWD)‐derived external control arms by determining the proportion of SATs on breast cancer and amyotrophic lateral sclerosis (ALS ...

Be like a Goldfish, Don't Memorize! Mitigating Memorization in Generative LLMs [PDF]

open access: yesarXiv
Large language models can memorize and repeat their training data, causing privacy and copyright risks. To mitigate memorization, we introduce a subtle modification to the next-token training objective that we call the goldfish loss. During training, randomly sampled subsets of tokens are excluded from the loss computation. These dropped tokens are not

1 min synthesis of phase pure nanocrystalline high‐entropy sulfides for efficient water electrolysis

open access: yesEcoEnergy, EarlyView.
High‐entropy sulphide spinels are synthesized with up to 8 different metal cations by an extremely short synthesis time of only 1 min and temperature of only 200–230°C. We further demonstrate the activity of the obtained nanosheets for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER).
