Spatially Regulated Silicon Clusters in Trimodal Composite Anodes for High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A trimodal anode architecture spatially regulates silicon clusters within confined interstitial environments formed by graphite and contorted hexabenzocoronene. This confinement suppresses silicon aggregation and localized stress while enabling efficient Li‐ion transport, achieving high‐capacity, stable lithium‐ion batteries.

Reversible Calcium Alloying on Bulk and Indium (Sub)‐Micro Negative Electrodes for Calcium‐Based Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Description: Indium metal serves as a reversible calcium‐alloying negative electrode. By transitioning from planar electrodes to powders and (sub‐)micron indium particles, the specific surface area is increased, improving the areal capacity density and cycling stability for calcium‐based batteries.

Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Remote Activation of Wnt Signaling and Cell Proliferation by E‐Cadherin Magnetomechanical Stimulation

open access: yesAdvanced Functional Materials, EarlyView.
A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.

XVII. Asrın İlk Yarısında İstanbul'da Tedavüldeki Sikkelerin Râici

open access: yesBelgeler, 1964
On altıncı asrın ikinci yarısında Osmanlı ekonomisi bir krizin tesiri alanına yavaş yavaş girmeğe başladı. Daha Kanuni'nin son yıllarından kendini duyuran kriz, gittikçe daha da kuvvetlendiği ve on yedinci asrın ilk yarısına kadar yayıldığı söylenebilir.

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts

open access: yesAdvanced Functional Materials, EarlyView.
The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...

Důsledky tzv. Šmalkaldské války z let 1546-1547 pro vývoj měnové integrace Evropy

open access: yesTheatrum Historiae, 2008
The author focuses on specific political factors that influenced the creation of II. Imperial Coinage Order of 1551. Every effort was made to reform and unify of coinage situation in the frame of the Holy Roman Empire (the Reich).

The Coinages and Monetary Policies of Henry VIII (r. 1509-1547): Contrasts between Defensive and Aggressive Debasements [PDF]

open access: yes
The renown or infamy of Henry VIII's Great Debasement (1542 - 1553), which the government of his successor, Edward VI, continued for another six years after his death, has unfairly obscured his earlier and far more modest coinage changes and public ...

Modulation of Surface‐Associated Transport in (Bi1‐xSbx)2Te3 via Battery‐ Inspired Solid‐State Iontronic Gating

open access: yesAdvanced Functional Materials, EarlyView.
Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...

Philippe II et les dieux

open access: yesKaranos, 2020
Macedonian kings kept close bonds with the divine sphere. They considered themselves as Heraklids (and, in consequence, they traced back their lineage to Zeus himself) and the kingship kept noteworthy religious functions.
