From classification medicine to clinical medicine (the end of the XVIII century - 1870s). Communication 5. Reforms in therapy in 1840s-1860s

open access: yesТерапевтический архив, 2012
Reforms of therapy in 1840-1860s are considered: development of the methods of objective assessment of efficacy of some methods of treatment, appearance of experimental pharmacology, introduction of anasthesia.

Experimental Realization of an NMR Quantum Switch [PDF]

open access: yesarXiv, 2004
In this paper, we report an experimental realization of quantum switch using nuclear spins and magnetic resonant pulses. The nuclear spins of H and C in carbon-13 labelled chloroform are used to carry the information, then nuclear magnetic resonance pulses are applied to perform either bypass or cross function to achieve the switching.

Unlocking High‐Performance in All‐Organic Solar Cells by the Development of Organic Electrodes with No Acid and High‐Temperature Treatment and the Effective Preparation Thereof on Organic Multilayer Films

open access: yesAdvanced Functional Materials, EarlyView.
The developed all‐organic solar cells achieve a power conversion efficiency of 8.7%, more than double the previous record. In addition, bioplastic substrates are used to produce environmentally friendly solar cells with an efficiency of 8.6%. These results are achieved by developing high‐performance organic electrodes without acid doping or high ...

Third-generation cylindrical dendrimers based on L-aspargic acid in solutions: hydrodynamic and electrooptical properties [PDF]

open access: yesarXiv, 2008
Samples of third-generation cylindrical dendrimers with molar masses ranging in the interval 20000...60000 have been studied by the methods of equilibrium and non-equilibrium electrical birefringence, molecular hydrodynamics and optics. It was found that the absolute values of Kerr and flow birefringence constants exceed the values obtained for ...

Enhanced performance in polymer photovoltaic cells with chloroform treated indium tin oxide anode modification

open access: yes, 2011
Enhanced performance of a poly(3-hexylthiophene):(6,6)-phenyl C61 butyric acid methyl ester bulk heterojunction polymer photovoltaic cell is reported by modifying the indium tin oxide (ITO) anode with chloroform solution.

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

open access: yesAdvanced Functional Materials, Volume 35, Issue 16, April 18, 2025.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...

Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

High‐Speed and Scalable Wet Spinning of Graphene/Liquid Crystalline Elastomer Composite Filaments

open access: yesAdvanced Functional Materials, EarlyView.
Polydomain filaments from graphene/liquid crystalline elastomer (LCE) composites are scalably‐manufactured by wet spinning across a wide range of diameters (≈137–1128 µm) at a speed up to 4500 m h−1 through a double diffusion coagulation mechanism, enabling fast actuation and optimized mechanical performance for broad applications.
