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

Memory erasure in small systems
, 2009 We consider an overdamped nanoparticle in a driven double-well potential as a generic model of an erasable one-bit memory. We study in detail the statistics of the heat dissipated during an erasure process and show that full erasure may be achieved by ...

Iontronic Regulation of Nanoconfined Electrical Double Layers on Dielectric Solids
Small 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 ...

An Explanation of the Landauer bound and its ineffectiveness with regard to multivalued logic
Technical Transactions, 2020 We discuss, using recent results on the thermodynamics of multivalued logic, the difficulties and pitfalls of how to apply the Landauer’s principle to thermodynamic computer memory models. The presentation is based on Szilard’s version of Maxwell’s demon

, 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 ...

Metabolic Origin, Role and Fate of the Denaturant Guanidine
Microbial 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.

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

DEMONIC programming: a computational language for single-particle equilibrium thermodynamics, and its formal semantics. [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 Maxwell's Demon, 'a being whose faculties are so sharpened that he can follow every molecule in its course', has been the centre of much debate about its abilities to violate the second law of thermodynamics.

Autonomous Artificial Molecular Motors and Pumps
ChemSystemsChem, Volume 7, Issue 5, September 2025.Autonomous energy consumption is the only way to introduce molecular motors into more sophisticated, larger systems, capable of life‐like behavior. We reviewed a selection of the most recent advances in the field molecular motors focusing on those capable of performing continuous and autonomous motion under constant experimental conditions, that is ...
