Brazilian Journal of Political EconomyIrving Fisher offered a ‘tentative’ debt-deflation theory of great depressions rather than a fully consistent theory of his ‘creed’: “I say ‘creed’ because, for brevity, it is purposely expressed dogmatically and without proof.

Toward a General Theory of Standards of Proof
SSRN Electronic Journal, 2010 Which standard of proof is best for a particular type of case? This deceptively simple question has been much discussed, but the current state of understanding is unsatisfactory. Statisticians posed a general answer; philosophers and others launched an assault on that answer; practically oriented scholars draw on both strains unsystematically; and ...

Advanced Functional Materials, EarlyView.Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

On Equivalence of Definition of the Energy-Momentum Tensor in General Relativity and Field Theory [PDF]
Iranian Journal of Astronomy and AstrophysicsThis work investigates a fundamental pedagogical question concerning the definition of the energy-momentum tensor in theoretical physics. Students learn the definition of energy-momentum tensor in the field theory and on the other hand a different ...

Advanced Functional Materials, EarlyView.Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics
Advanced Functional Materials, EarlyView.Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.

Formation of Quasi‐Decoupling Interface on Li‐Metal Anodes in High Donor Electrolyte
Advanced Functional Materials, EarlyView.Li‐metal anode (LMA) is stabilized by introducing Li2Te2 as an electrolyte additive for Li‐metal batteries. Upon contact with Li, Li2Te2 spontaneously converts to Li2Te, which electronically isolates Li from dimethyl sulfoxide due to its large bandgap and minimal Bader charge transfer.
