Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Hendrik Stoker as mens

open access: yesKoers : Bulletin for Christian Scholarship, 1964
Dis met gemengde gevoelens dat ek die versoek aanvaar het om iets te skryf na aanleiding van die feit dat prof. H. G. Stoker op 4 April 1964 sy vyfensestigste verjaarsdag gevier het: dankbaarheid om ’n mooi lewe van diens aan sy kerk, sy volk, die ...

Drop‐on‐Demand Printed Negative Dielectric Anisotropy Liquid Crystal Droplets for Adaptive Complex Beam Manipulation and Assessment

open access: yesAdvanced Functional Materials, EarlyView.
Printed negative‐dielectric‐anisotropy liquid‐crystal droplets enable multidimensional full‐vectorial optical‐field sensing across polarization, phase, and wavelength, while also generating tunable skyrmionic‐like complex optical fields. ABSTRACT Adaptive manipulation of vectorial optical fields is important for optical metrology, imaging, and ...

Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride

open access: yesAdvanced Functional Materials, EarlyView.
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Frankenstein, de Mary Shelley, e Drácula, de Bram Stoker: gênero e ciência na literatura [PDF]

open access: yesHistória, Ciências, Saúde: Manguinhos, 2001
As obras literárias têm, através dos tempos, dado voz aos medos e esperanças gerados pelas descobertas científicas e retratado as imagens e mitos em torno da própria idéia de ciência.

Wat is in die Ekonomie eintlik Ekonomies?

open access: yesKoers : Bulletin for Christian Scholarship, 1959
In vorige uitgawes van Koers het veral prof. H. G. Stoker met hierdie probleem geworstel. Reeds daarvoor het ek ook in Koers aangedui dat daar ook in die Sosiologie ’n soortgelyke onopgeloste probleem bestaan, en ook elders.

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of
