Synthesis of fibroin/silica adsorbent for thin layer chromatography

Хімія, фізика та технологія поверхні
The main aim of this work is to synthesize microspherical fibroin/silica adsorbent through a one-step in situ synthesis that integrates silk fibroin into the hydrolytic polycondensation of tetraethoxysilane (TEOS). The kinetics of the sol-gel process is

High‐Mobility Chalcogenophene‐Engineered Diketopyrrolopyrrole Mixed Ionic‐Electronic Conductors With Doping Tolerance for Low‐Power Organic Electrochemical Transistors

Advanced Materials, EarlyView.
Chalcogen substitution emerges as a powerful strategy for designing high‐performance OMIECs. In aliphatic–glycol side chain diketopyrrolopyrrole polymers, biselenophene incorporation promotes a planar, polarizable, and doping‐tolerant quinoidal framework, enabling PDPP‐4EG‐Se2 to combine high hole mobility, large µC*, enhanced operational stability ...

Thin-layer chromatography of tissue lipids without extraction

Journal of Lipid Research, 1970
Frozen tissue sections were applied directly to silica gel plates, and the lipids were separated by developing the plates in different solvent systems.

From Dark Photocatalysis to Photobattery‐Type Operation: A Re‐Functionalized Ti‐MOF for Solar Energy Storage

Advanced Materials, EarlyView.
ReCl47‐bpy is developed as a solar‐rechargeable, Re‐functionalized two‐dimensional metal–organic framework (MOF) for light‐driven charge storage and dark utilization. Re–bipyridine sites stabilize photoinduced electrons, enabling two complementary configurations: a MOF suspension for long‐lived charge retention and dark H2 evolution, and a spin‐coated ...

Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing

Advanced Materials Interfaces, EarlyView.
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...

Obtenção de biodiesel por transesterificação em dois estágios e sua caracterização por cromatografia gasosa: óleos e gorduras em laboratório de química orgânica

Química Nova, 2013
Methanolic transesterification of oils and fats was carried out in a two steps procedure, under basic and acidic catalysis. Palm, soybean, canola, corn, rice, grapeseed, sunflower, peanut, pequi and olive oils, besides tallow and lard were used as ...

Interface‐Driven Control of Vanadium Carbide Micro‐ and Nanocrystal Growth During Chemical Vapor Deposition

Advanced Materials Interfaces, EarlyView.
A wrapped copper–vanadium interface enables reliable chemical vapor deposition growth of vanadium carbide micro‐ and nanocrystals. Adjusting methane supply shifts the process from the formation of many small crystals toward lateral expansion and merging of larger domains, while longer growth increases surface coverage without changing the cubic ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...
