Entropy‐Driven Physical Amplification in Multivalent Biosensing

open access: yesAdvanced Science, EarlyView.
Detecting scarce molecules usually demands enzymatic amplification such as PCR. A statistical‐mechanical theory now reveals a purely physical alternative: distributing a fixed binding strength over more linker arms exponentially lowers the concentration at which multivalent sensors switch on.

Minimal Transport Units Govern Oxygen‐Defect Stabilization and Transport for Lightweight Solid Electrolytes

open access: yesAdvanced Science, EarlyView.
Lightweight borate chemistry combined with minimal transport units provides a new pathway for designing lightweight oxide‐ion solid electrolytes. ABSTRACT Solid electrolytes are central to electrochemical energy technologies, including fuel cells, sensors, catalysis, membrane separation, and electrolyser.

Density estimators through Zero Variance Markov Chain Monte Carlo [PDF]

open access: yes
A Markov Chain Monte Carlo method is proposed for the pointwise evaluation of a density whose normalizing constant is not known. This method was introduced in the physics literature by Assaraf et al (2007).

Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

open access: yesAdvanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...
