Introduction to flexible nanomaterials: microscopic mechanisms and macroscopic applications.

Yuan Cheng, Zibiao Li, Junfeng Gao, Hai-Dong Yu and Gang Zhang introduce this themed collection on flexible nanomaterials.

Stoichiometry-grain size-specific capacitance interrelationships in nickel oxide.

Nickel oxide exhibits almost the highest theoretical specific capacitance ( ), which includes contributions from non-faradaic double layer charging and faradaic OH adsorption. However, the realistic and tangible is due to the faradaic process, which can be influenced by chemical ( stoichiometry) and structural ( grain size) changes. Hence, it is necessary to investigate the interrelationships among chemical and structural features and charge storage capacity.

Room-temperature synthesized SnO electron transport layers for efficient perovskite solar cells.

Tin oxide (SnO) is widely used as electron transport layer (ETL) material in perovskite solar cells (PSCs). Numerous synthesis methods for SnO have been reported, but they all require a proper thermal treatment for the SnO ETLs. Herein we present a simple method to synthesize SnO nanoparticles (NPs) at room temperature.

On the axiomatic foundations of the integrated information theory of consciousness.

The integrated information theory (IIT) is one of the most influential scientific theories of consciousness. It functions as a guiding framework for a great deal of research into the neural basis of consciousness and for attempts to develop a consciousness meter. In light of these developments, it is important to examine whether its foundations are secure.

The beta3-adrenoceptor agonist 4-[[(Hexylamino)carbonyl]amino]-N-[4-[2-[[(2S)-2-hydroxy-3-(4-hydroxyphenoxy)propyl]amino]ethyl]-phenyl]-benzenesulfonamide (L755507) and antagonist (S)-N-[4-[2-[[3-[3-(acetamidomethyl)phenoxy]-2-hydroxypropyl]amino]-ethyl]phenyl]benzenesulfonamide (L748337) activate different signaling pathways in Chinese hamster ovary-K1 cells stably expressing the human beta3-adrenoceptor.

This study identifies signaling pathways activated by the beta(2)-/beta(3)-adrenoceptor (AR) agonist zinterol, the selective beta(3)-AR agonist L755507, and the selective beta(3)-AR antagonist L748337 in CHO-K1 cells expressing human beta(3)-adrenoceptors. Zinterol and L755507 caused a robust concentration-dependent increase in cAMP accumulation (pEC(50) values of 8.5 and 12.

Alcohol consumption and computer blackjack.

The authors considered compliance with a decision aid that E. Thorp (1966) designed to minimize loss in a gambling paradigm under different levels of risk or impairment. Twenty adult men (aged 18-46) completed the South Oaks Gambling Screen (SOGS; H.

Ligand-directed signaling at the beta3-adrenoceptor produced by 3-(2-Ethylphenoxy)-1-[(1,S)-1,2,3,4-tetrahydronapth-1-ylamino]-2S-2-propanol oxalate (SR59230A) relative to receptor agonists.

This study examines signaling pathways activated by the mouse beta(3)-adrenoceptor (AR) expressed in Chinese hamster ovary cells at high (CHObeta(3)H) or low (CHObeta(3)L) levels. Functional responses included extracellular acidification rate (ECAR), cAMP accumulation, and p38 mitogen-activated protein kinase (MAPK) or extracellular signal-regulated protein kinase 1/2 (Erk1/2) phosphorylation. (-)-Isoproterenol and the beta(3)-AR agonist (R, R)-5-[2-[[2-(3-chlorophenyl)-2-hydroxyethyl]-amino]-propyl]1,3-benzodioxole-2,2-decarboxylate (CL316243) caused concentration-dependent increases in cAMP accumulation and ECAR in CHObeta(3)H and CHObeta(3)L cells.

Electrolocation in the platypus--some speculations.

In the platypus, electroreceptors are located in rostro-caudal rows in skin of the bill, while mechanoreceptors are uniformly distributed across the bill. The electrosensory area of the cerebral cortex is contained within the tactile somatosensory area, and some cortical cells receive input from both electroreceptors and mechanoreceptors, suggesting a close association between the tactile and electric senses. Platypus can determine the direction of an electric source, perhaps by comparing differences in signal strength across the sheet of electroreceptors as the animal characteristically moves its head from side to side while hunting.
