Advanced Science, EarlyView.By grafting dense long double‐brush chains, we synthesized bottlebrush networks with high theoretical enthalpy. Their low entanglement, combined with dynamic bonds, promotes crystalline domain reorganization and minimizes enthalpy loss, achieving a record enthalpy of 240.7 J·g−1.

Bipolar Hydrogen Production from a Hybrid Alkaline‐Acidic Formaldehyde‐Proton Fuel Cell
Advanced Science, EarlyView.A novel hybrid alkaline‐acidic formaldehyde‐proton fuel cell (FPFC) was developed by coupling alkaline formaldehyde oxidation reaction (FOR) with acidic hydrogen evolution reaction (HER). This design enables concurrent bipolar H2 production and electricity generation.

Intermittent many-body dynamics at equilibrium [PDF]
, 2017 The equilibrium value of an observable defines a manifold in the phase space of an ergodic and equipartitioned many-body system. A typical trajectory pierces that manifold infinitely often as time goes to infinity.

Advanced Science, EarlyView.This study elucidates how steric hindrance in amines creates a dual effect in CO2 capture: it thermodynamically favors the reaction by shifting the pathway from carbamate to alkyl carbonate formation, increasing capacity and lowering regeneration heat, while simultaneously slightly slowing the kinetics.

Quantum Chaos and Quantum Randomness—Paradigms of Entropy Production on the Smallest Scales
Entropy, 2019 Quantum chaos is presented as a paradigm of information processing by dynamical systems at the bottom of the range of phase-space scales. Starting with a brief review of classical chaos as entropy flow from micro- to macro-scales, I argue that quantum ...

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?
ChemistryEurope, EarlyView.Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

A New Perspective on Classical Ideal Gases
Entropy, 2013 The ideal-gas barometric and pressure laws are derived from the Democritian concept of independent corpuscles moving in vacuum, plus a principle of simplicity, namely that these laws are independent of the kinetic part of the Hamiltonian.

Quasi-particle spectrum and entanglement generation after a quench in the quantum Potts spin chain
, 2018 Recently, a non-trivial relation between the quasi-particle spectrum and entanglement entropy production was discovered in non-integrable quenches in the paramagnetic Ising quantum spin chain.

Partial identification with categorical data and nonignorable missing outcomes
Canadian Journal of Statistics, EarlyView.Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.
