Parametric Study of an Air Charged Franchot Engine with Novel Hot and Cold Isothermalizers

open access: yesInventions, 2017
The Stirling engine is an external combustion engine that uses heat exchangers to enhance the addition and removal of energy. This makes the engine power-dense but expensive, less efficient and complicated. In this contribution, the Stirling engine based

One‐Step Electrodeposition of Iron Oxyhydroxide Onto 3D Porous Graphene Substrates for on Chip Asymmetric Micro‐Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A micro‐supercapacitor with electrodeposited iron oxyhydroxide (FeOOH) as the negative electrode and birnessite manganese oxide (MnO2) as the positive electrode achieves a 2 V working voltage, stable cycling in an aqueous electrolyte, and high energy and power densities of 21 μWh cm‐2 and 2.5 mW cm‐2 respectively.

Asymmetric Organocatalytic Synthesis of Sulfone‐Containing (Dihydro)pyrans via Formal (4+2)‐Cycloadditions of Allenylsulfones or Propargylsulfones and Michael Acceptors

open access: yesChemCatChem, Accepted Article.
The activation of electron poor allenes with Lewis base catalysts allows for unique transformations and chiral isochalcogenoureas were recently introduced as powerful catalysts for allenoate‐based (4+2)‐cycloadditions. We herein now report the use of these catalysts for the activation and control of allenylsulfones and propargylsulfones for asymmetric (

Relational Responsibility and Host Communities in Complex and Contentious Environmental Situations: Coastal Fisheries and Treated Water at the Fukushima Dai'ichi Nuclear Plant, Japan

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Treated water releases into the Pacific from the Fukushima Dai'ichi nuclear plant in Japan have drawn opposition from fishing communities, who accused proponents of acting irresponsibly in commencing releases before gaining local support. The controversy reflects questions in social licence to operate and social impact assessment about how ...

Electrophoresis of polyelectrolyte‐adsorbed soft particle with hydrophobic inner core

open access: yesELECTROPHORESIS, EarlyView.
Abstract This article deals with the electrophoresis of hydrophobic colloids absorbed by a layer of polymers with an exponential distribution of the polymer segments. The functional groups present in the polymer layer further follow the exponential distribution.
