Resolving aging dynamics of a 3D colloidal glass
Physical aging is an inherent property of glassy matter, but understanding its microscopic mechanism remains a challenge particularly at the particle level. In this work, we use a confocal microscope to in-situ t...

Effective Energy Density of Glass Rejuvenation
Glasses with rejuvenated structures usually exhibit improved room-temperature plasticity, which facilitates their applications. However, glass rejuvenation requires external energy injection to “shake up” the ...

Cu/Fe Bimetallic Modified Fly Ash: An Economical Adsorbent for Enhanced Phosphorus Removal from Aqueous Solutions
Excessive phosphorus in water causes eutrophication and leads to the ecological unbalance. The main treatment for eutrophication is to remove the phosphorus in aqua system effectively and efficiently. A compos...

Unraveling the threshold stress of structural rejuvenation of metallic glasses via thermo-mechanical creep
The competition between physical aging and structural rejuvenation determines the physical and mechanical properties of glassy materials. Thus, the rejuvenation-aging boundary must be identified quantitatively...

Synthesis and Characterization of a Novel Preceramic Polymer for SiBNC Ceramic Fibers
A new approach for the synthesis of polymer precursor for quaternary SiBNC fibers is presented. The inexpensive, commercially available reactants n-propylamine (C3H7NH2), trichlorosilane (SiHCl3) and boron trichl...

How does the initial free volume distribution affect shear band formation in metallic glass?
Introducing heterogeneities into the structure is an effective way to enhance the plasticity in metallic glasses (MGs). As natural heterogeneity, the original randomly distributed free volume in MGs has been f...

Equivalent Model of Expansion of Cement Mortar Under Sulphate Erosion
The expansion property of cement mortar under the attack of sulfate ions is studied by experimental and theoretical methods. First, cement mortars are fabricated with the ratio of water to cement of 0.4, 0.6, ...
