The Frontiers of Aqueous Zinc–Iodine Batteries: A Comprehensive Review on Mechanisms, Optimization, and Industrial Prospects

open access: yesAdvanced Functional Materials, EarlyView.
This review provides an in‐depth understanding of all theoretical reaction mechanisms to date concerning zinc–iodine batteries. It revisits the inherent issues and solutions of zinc–iodine batteries from the perspective of industrial application. By integrating existing examples of energy storage applications, it identifies the challenges faced on the ...

A mathematical and experimental simulation of the hematological response to weightlessness

open access: closedActa Astronautica, 1979
Two ground-based methods of weightlessness simulation--a computer model of erythropoiesis feedback regulation and bedrest--were used to investigate the mechanisms which lead to loss of red cell mass during spaceflight. Both methods were used to simulate the first Skylab mission of 28 days.

A SURVEY OF CHRONIC WEIGHTLESSNESS SIMULATION IN BIOLOGICAL RESEARCH [PDF]

open access: closed, 1964
Abstract : The central emphasis of the survey concerns the status of research involving various methods of effecting chronic weightlessness for organisms. Three general types of approach are considered: (1) accelerations that oppose the Earth's gravity, (2) indirect reduction of gravitational effects, and (3) indirect information from increases of ...

Simulation of Weightlessness

open access: closed, 1986
The phenomenon of gravitation is characterized by the mutual attraction of any two bodies. The universal character of gravitation was first recognized by Isaac Newton who found the well-known law for the attraction force F acting between two mass points or homogeneous spherical bodies $$\rm F\, = \,\gamma Mm/R^2 $$ (3.1) M, m are the masses ...

[Weightlessness or weightlessness simulation and vascular remodeling].

open access: closedHang tian yi xue yu yi xue gong cheng = Space medicine & medical engineering, 2003
Weightlessness is inavoidable during spaceflight. It brings profound physiological effects on human body. Vascular remodeling is one of the important changes of cardiovascular system caused by weightlessness or simulated weightlessness. The paper summarized the studies on the effects of weightlessness or weightlessness simulation on vascular remodeling

Exercise response to simulated weightlessness

Acta Astronautica, 1979
Two bed rest analog studies of space flight were performed; one 14 d and the other 28 d in duration. Exercise response was studied in detail during the 28 d study and following both the 14 d and 28 d studies. This paper relates the results of these studies to physiologic changes noted during and following space flight.
