CMB B-modes, spinorial space-time and Pre-Big Bang (II) [PDF]

open access: yes, 2014
The BICEP2 collaboration reported recently a B-mode polarization of the cosmic microwave background (CMB) radiation inconsistent with the null hypothesis at a significance of > 5 {\sigma}.

Dual‐Interface‐Dominant Cathode Architectures Enabling Fast Sulfur Redox and Stable Interfaces in All‐Solid‐State Li‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An optimized carbon host nanostructure enables a dual‐interface‐dominant architecture in sulfur cathodes of solid‐state Li‐S batteries by selectively forming sulfur|carbon and sulfur|solid electrolyte interfaces. This tailored interfacial configuration accelerates sulfur redox kinetics by establishing enriched Li+/e– transport networks, while ...

Evaluating Global Warming Potentials as Historical Temperature Proxies: an application of ACC2 Inverse Calculation [PDF]

open access: yes
Global Warming Potentials (GWPs) are evaluated as proxies of the historical temperature by applying them to convert historical CH4 and N2O emissions to equivalent CO2 emissions.

Pixelation‐Free, Monolithic Iontronic Pressure Sensors Enabling Large‐Area Simultaneous Pressure and Position Recognition via Machine Learning

open access: yesAdvanced Functional Materials, EarlyView.
A pixelation‐free, monolithic iontronic pressure sensor enables simultaneous pressure and position sensing over large areas. AC‐driven ion release generates spatially varying impedance pathways depending on the pressure. Machine learning algorithms effectively decouple overlapping pressure–position signals from the multichannel outputs, achieving high ...

Temperature‐Induced Nonvolatile Switching through Thermal Hysteresis in a Gd3Fe5O12/Ho3Fe5O12 Exchange‐Coupled Rare‐Earth Iron Garnet Bilayer

open access: yesAdvanced Functional Materials, EarlyView.
Reducing power consumption in spintronic memory remains a major challenge due to the need for high current densities. A bilayer of gadolinium and holmium iron garnets enables purely temperature‐induced, nonvolatile magnetic switching with bistable states within a ±25 K range. This approach achieves up to 66‐fold lower energy use than current spin–orbit

Le quotidien et les média [PDF]

open access: yes, 2007
La question que j’aimerais soulever est la suivante: quand de nos jours le temps a perdu les différents accents qu’il peut prendre, «l’accent aigu de l’actualité, l’accent grave de l’historicité et l’accent circonflexe de l’éternité» (Paul Celan ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

open access: yesAdvanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...
