Electrical Maxwell demon and Szilard engine utilizing Johnson noise, measurement, logic and control. [PDF]

open access: yesPLoS ONE, 2012
We introduce a purely electrical version of Maxwell's demon which does not involve mechanically moving parts such as trapdoors, etc. It consists of a capacitor, resistors, amplifiers, logic circuitry and electronically controlled switches and uses ...

Photonic Maxwell's demon

open access: yes, 2015
We report an experimental realisation of Maxwell's demon in a photonic setup. We show that a measurement at the single-photon level followed by a feed-forward operation allows the extraction of work from intense thermal light into an electric circuit ...

Iontronic Regulation of Nanoconfined Electrical Double Layers on Dielectric Solids

open access: yesSmall Science, Volume 5, Issue 11, November 2025.
In this review, the evolution from classical EDL models at conductor‐liquid interfaces to extended frameworks for nonconductor‐liquid systems is revisited. Building upon this foundation, the implemented energy and information technologies are systematically classified based on the dynamic regulation strategies of different EDL substructures ...

Axiomatic Information Thermodynamics

open access: yesEntropy, 2018
We present an axiomatic framework for thermodynamics that incorporates information as a fundamental concept. The axioms describe both ordinary thermodynamic processes and those in which information is acquired, used and erased, as in the operation of ...

Membrane Proteins as Maxwell’s Demons and Their Significance for P Systems [PDF]

open access: yes, 2008
The aim of these notes is to contribute to the dialog between P systems and Biological Sciences focussing on membrane proteins involved either in iron transport inside the bacterial cells or in elimination outside the bacterial cells of substances ...

Metabolic Origin, Role and Fate of the Denaturant Guanidine

open access: yesMicrobial Biotechnology, Volume 18, Issue 11, November 2025.
The origin of metabolic guanidine is largely a mystery. We suggest it is created when guanine‐containing nucleotides are oxidised by molecular oxygen instead of being broken down into urea as purines normally would. Guanidine may act as a signal to help cells control the level of reactive oxygen species.

Nonlinear bosonic Maxwell’s demon by coupling to qubits

open access: yesCommunications Physics
The concept of Maxwell’s demon, proposed in classical physics as a means to extract work from a thermodynamics system beyond the constraints set by the second law of thermodynamics, has since been extended to modern quantum physics.

Limits of Landauer’s principle and of the second law of thermodynamics

open access: yesEntropie
Since 1857, the second law of thermodynamics has faced the challenge of Maxwell’s imagined demon. The widely accepted response to this challenge suggests that the demon requires a bit of information to work, and according to Landauer’s principle ...

A Modified Szilard's Engine: Measurement, Information, and Maxwell's Demon

open access: yesEntropy, 2004
: Using an isolated measurement process, I've calculated the effect measurement has on entropy for the multi-cylinder Szilard engine. This calculation shows that the system of cylinders possesses an entropy associated with cylinder total energy states ...

A 15‐Year Time Series Shows Major Declines in Whale Sharks in Southern Mozambique

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 10, October 2025.
ABSTRACT A 15‐year dataset (2005–2019) of 706 photo‐identified whale sharks (Rhincodon typus) off Praia do Tofo in Mozambique allowed us to assess the local abundance trend, and size‐ and sex‐specific sighting and abundance trends, using both generalised additive models and capture–mark–recapture models.
