Small, EarlyView.Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.

Energies, 2018 The loss of kinetic energy of moving parts due to viscous friction of lubricant causes the reduction of piston pump efficiency. The viscosity of lubricant film is mainly affected by the thermal effect. In order to improve energy efficiency of piston pump,

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy
Journal of Synchrotron Radiation, EarlyView.For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Journal of Synchrotron Radiation, EarlyView.A 4D X‐ray computed tomography experimental campaign was carried out on a porous carbonate rock to investigate the link between initial porosity and deformation modes. This paper presents the experiment and the methods used to explore this relationship.The study of the mechanical behaviour of carbonate rocks has benefited from the evolution of ...

Facilitating Feeling?: The Relationship between Memorials and Emotions
Sociological Inquiry, EarlyView.This article explores if and how national memorials impact collective emotions among local residents, focusing on the National Memorial for Peace and Justice (NMPJ) in Montgomery, Alabama. This understudied question is of sociological importance given the change in federal policy regarding public memorials, particularly the removal of references to ...

Experimental Physiology, EarlyView.Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Characteristic Study of a Valve-Matched Flow Single-Piston Miniature Water-Hydraulic Pump
IEEE AccessA miniature single-piston valve flow-matching water-hydraulic pump is described in this paper, which designs with a unique double-face cam mechanism to achieve the reciprocating motion of the piston and a new flow-matching valve to adapt to the ...

Experimental Physiology, EarlyView.Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.
