Binary Nanoparticle Combinations in Acetone‐Based Working Fluids for Thermal Performance Enhancement of Evacuated Tube Solar Water Collectors

open access: yesEnergy Science &Engineering, Volume 14, Issue 4, Page 2277-2293, April 2026.
Illustration of the work. ABSTRACT This experimental investigation evaluates the thermal performance enhancement of evacuated tube solar water collectors through the implementation of binary nanofluid formulations using acetone as the base fluid. Three metal oxide nanoparticles, including magnesium oxide (MgO), copper oxide (CuO), and titanium dioxide (

Lunar radiator shade [PDF]

open access: yes, 1992
An apparatus for rejecting waste heat from a system located on or near the lunar equator is presented. The system utilizes a reflective catenary shaped trough deployed about a vertical radiator to shade the radiator from heat emitted by the hot lunar ...

From agnosis to accidental activism: Infinite regress and the Post Office Scandal

open access: yesJournal of Law and Society, Volume 53, Issue S1, Page S25-S41, April 2026.
Abstract This paper explores the lived experiences of victims/survivors affected by the UK Post Office Scandal, drawing on 28 in‐depth interviews and critical legal analysis. It uses the concept of ‘accidental activism’ to explore how victims, initially isolated and disempowered, became central agents of justice reform.

A computational model for retinal haemodynamics under gravitational and postural variations

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 2698-2716, 1 April 2026.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...

Overproduction of 42 Amino Acids Long Amyloid Beta Leads to Activation of Secretory Autophagy and Development of Drusen‐Like Structures Originating From Retinal Pigment Epithelium

open access: yesThe FASEB Journal, Volume 40, Issue 5, 15 March 2026.
The role of 42 amino acids long amyloid beta (Aβ) in the retinal pigment epithelium (RPE) was investigated using 5xFAD mice model overproducing Aβ. The RPE cells of 5xFAD mice showed increased oxidative stress, accumulation of autophagy‐destined proteins, increased expression of secretory autophagy markers, and increase in epithelial‐to‐mesenchymal ...
