Ein einfacher Lichtabsorptionsdetektor für die Durchlauf-Dünnschichtchromatographie

CHIMIA, 1976
Description is given of a photometric detector for continuousflow thin-layer chromatography. The detection takes place directly on the thin-layer foil during the separation of sample components. The detector has a maximum of sensitivity at 550 nm.

Influence of homo-buffer layer on stress control of sputtered (Ba0.45,Sr0.55)TiO3 thin films on Pt-Si [PDF]

arXiv, 2013
To engineer strain relaxation of sputtered BST thin films on Pt-Si wafers, homo-buffer layer method was applied to eliminate Pt hillock formation. Thin BST homo-buffer layers were deposited at room temperature and subsequently the main BST layer was deposited at 650{\deg}C, Pt hillock free BST films were obtained with homo-buffer thickness above 5 nm ...

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

Advanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

Oxalate-silica gel thin-layer system for free 2-hydroxy fatty acids and for fatty acyl coenzyme A

Journal of Lipid Research, 1972
The 2-hydroxy fatty acids tend to yield streaks in thin-layer chromatography on silica gel plates. If potassium oxalate is included with binder-free silica gel, good spots are obtained.

Delivery of Islatravir via High Drug‐Load, Long‐acting Microarray Patches for the Prevention or Treatment of Human Immunodeficiency Virus

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Islatravir‐loaded dissolving microarray patches (MAPs) provide a minimally invasive, long‐acting solution for HIV‐1 prevention and treatment. In rats, sustained islatravir delivery lasts up to three months, while in minipigs, efficacious plasma levels are detected for six days.

Dendrimer Conjugates with PD‐L1‐Binding Peptides Enhance In Vivo Antitumor Immune Response

Advanced Healthcare Materials, EarlyView.
In this paper, a novel nanoparticle scaffold composed of dendrimers conjugated with peptide‐based immune checkpoint inhibitors, enhancing drug delivery efficacy is introduced. By conjugating PD‐L1‐binding peptides to dendrimers, multivalent binding effects are harnessed, resulting in enhanced binding affinity, prolonged half‐life, and improved ...

Determination of Trace Moisture Content in Dimethylacetamide by Gas Chromatography [PDF]

arXiv, 2018
Dimethylacetamide is used as a solvent in polymer processing and moisture in DMA affects the morphology and mechanical properties of the polymer products. This paper describes a method for determination of trace moisture content in DMA by acetylene production - gas chromatography. In the condition of 30 centigrade and ultrasonic dispersion, moisture in

Conductive Polymer Coatings Control Reaction Selectivity in All‐Iron Redox Flow Batteries

Advanced Materials, EarlyView.
Aqueous redox flow batteries are limited by the competing hydrogen evolution reaction (HER) at their negative electrodes. In this work, conductive polymers are conformally coated on porous carbonaceous electrodes to improve the reaction selectivity of hybrid all‐iron redox flow batteries.

Empowering Machines to Think Like Chemists: Unveiling Molecular Structure-Polarity Relationships with Hierarchical Symbolic Regression [PDF]

arXiv
Thin-layer chromatography (TLC) is a crucial technique in molecular polarity analysis. Despite its importance, the interpretability of predictive models for TLC, especially those driven by artificial intelligence, remains a challenge. Current approaches, utilizing either high-dimensional molecular fingerprints or domain-knowledge-driven feature ...

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

Advanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.
