Design of Fuel‐Dependent, Complex‐Coacervate‐Based Synthetic Cells

open access: yesChemistry – A European Journal, EarlyView.
Fuel‐dependent synthetic cells form and persist only in the presence of chemical fuel, decaying under starvation. We establish design rules for hexapeptide‐based coacervates, showing that tryptophan enhances polyanion binding, extends lifetime, and reduces waste sensitivity.

Sustainability strategies for organic food and farming [PDF]

open access: yes, 2005
Local organic food should be an accessible alternative, both concerning availability and price, for a citizen-consumer influencing through food choices, and for the rural poor.

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam

open access: yesChemie Ingenieur Technik, EarlyView.
This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

Genomic Insights Into Risperidone Treatment Outcomes in Children and Adolescents: Experience From a Psychiatric Hospital Serving Rural Youth

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Risperidone is a commonly used antipsychotic for treating psychiatric illness in children and adolescents. There is a large variability in risperidone response and discontinuation rates remain high. Pharmacogenomics offers the opportunity to improve risperidone outcomes, yet studies in pediatric populations are limited.

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

open access: yesDrug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Determination of THC and THC‐COOH in Dried Capillary Blood Spots and Comparison to Venous Blood of Recreational Cannabis Consumers in a Pilot Study

open access: yesDrug Testing and Analysis, EarlyView.
A new extraction method was developed and validated for the extraction of THC and THC‐COOH from capillary blood samples collected as dried blood spots. The extracts were analysed using HPLC–MS/MS resulting in high extraction efficiencies for both THC and THC‐COOH.

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...
