Fish Theory: Gravity in a Superfluid Wave Medium
No full textFish Theory proposes a unified interpretation of gravitational and collective behavior — from atomic particles to galaxies — inspired by the fluid coordination of fish.
This model reimagines gravity through wave-fluid interactions, challenging traditional spacetime frameworks, and suggesting that the universe behaves more like a responsive medium than a static stage.

Utilization of cobalt bis(terpyridine) metal complex as soluble redox mediator in Li-O2 batteries
No full textRedox mediators hold significant promise in reducing the large overpotentials pervasive upon charging of lithium-oxygen (Li-O2) cells. Cobalt bis(terpyridine) (Co(Terp)2) was investigated as mediator of the Li2O2 oxidation reaction using electrochemical, XRD and mass spectrometry measurements and benchmarked against tetrathiafulvalene (TTF). Significant reductions in reversible potential versus Li+/Li are measured for Co(Terp)2 and TTF from diglyme to Pyr14TFSI:diglyme to Pyr14TFSI, attributable to upward shift in the Li+/Li, due to weakening Li+ solvation in this solvent order. The lowering of the reversible potentials has noticeable gains on the kinetics of the charge reaction and greater reduction in charge overpotential are observed with the cobalt complex. However, probing the efficacy of the discharge and charge processes using differential electrochemical mass spectrometry reveal that Co(Terp)2 undergoes CoII to CoI reduction on cell discharge which interferes with the desired O2 reduction; furthermore less than 25% of the O2 consumed on discharge is recovered on charge. On the other hand, TTF allows the ideal 2 e-/O2 on discharge and enables up to 32% O2 recovery on charge. CO2 is a significant charging product as voltages becomes greater than 4.0 V vs. Li+/Li because of electrolyte decomposition. The methodology here developed is valuable to critically evaluate the effectiveness of redox agents in Li-O2 batteries

No full textDemythologizing the sacred: F. Scott Fitzgerald\u27s The Great Gatsby as a misnomer
No full textThe first moment the reader catches sight of the cover of F. Scott Fitzgerald\u27s novel The Great Gatsby, the thing that most immediately strikes him is the \u27greatness\u27 of the eponymous character which is taken for granted as early as the very title given to it. Nevertheless, as the book unfolds, the reader comes to realize the irony that lies behind this title, thereby conjuring up the old saying "all that glitters is not gold ". Surprisingly enough, the title turns out to be no more than a mere misnomer ironically referring to a racketeer whose ill-gotten money makes of him a prominent person. The present article attempts to demythologize the ideals, if it is in anyway meaningful to call them so, of Gatsby who is considered to be great and venerable. In demythologizing Gatsby, the article challenges such values as romanticism, the American Dream and the new American elite, if not modern Western society values, held by him. This is done through dismantling the mythical and mysterious elements from Gatsby\u27s character, thereby dealing with him as an ordinary, if not \u27ungreat\u27, man
Quantitative analyses of enhanced thermoelectric properties of modulation-doped PEDOT:PSS/undoped Si (001) nanoscale heterostructures
No full textPoly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) has high electrical conductivity (∼10³ S cm⁻¹) but it exhibits a low Seebeck coefficient (<15 μV K⁻¹), resulting in a low power factor. Mixing PEDOT:PSS with nanostructured semiconductors can enhance the Seebeck coefficient and achieve an improved thermoelectric power factor. However, underlying mechanisms for those composite thermoelectric systems are scarcely understood so far. In this study, quantitative analyses on the electrical conductivity and Seebeck coefficient for the heterostructures of nanometer-thick PEDOT:PSS on single-crystal Si (001) on sapphire (SOS) are reported. The heterostructures have larger Seebeck coefficients up to 7.3 fold and power factors up to 17.5 fold relative to PEDOT:PSS. The electrical conductivity increased with decreasing combined thicknesses of PEDOT:PSS and Si, and the Seebeck coefficient increased with decreasing PEDOT:PSS thickness, which can be attributed to modulation doping caused by diffusion of holes from PEDOT:PSS into undoped Si. This hypothesis is supported by simulation per band alignment. The valence band offset between Si and PEDOT:PSS dominantly controls the electrical conductivity and Seebeck coefficient of the heterostructures. This study not only suggests mechanistic insights to increase the power factors of PEDOT:PSS-based composites but also opens the door for new strategies to enhance the thermoelectric efficiencies of heterostructured nanocomposite materials
