Glasses have played a critical role in the development of modern civilization and will
continue to bring new solutions to global challenges from energy and the environment to …

The hardness properties of materials are tracked from early history until the present time.
Emphasis is placed on the hardness test being a useful probe for determining the local …

Sapphire, widely used in high-speed integrated-circuit chips, thin-film substrates, and
various electronic components, is regarded as one of the most difficult to cut materials owing …

Potential for obtaining stronger glass products is discussed. Flaws, mostly forming‐and
handling‐generated and accelerated crack growth due to surrounding environment appear …

Glass has provided many life‐changing products over the past millennia to improve the
quality of human living. In this “International Year of Glass 2022” paper, we review the …

A methodology is described for characterizing the spatial distribution of thermal mismatch
stresses at grain level in B 4 C-SiC-Si ceramic composites using Raman spectroscopy …

Traditional anti‐impact armors and shields are normally made of stiff and hard materials and
therefore deficient in flexibility. This greatly limits their applications in protecting objects with …

The cross scratching experiments were carried out on C-and M-planes of sapphire to
investigate the crystal-orientation dependence of crack initiation and damage mechanism …

Mechanical properties of glasses can be significantly increased by inducing surface
crystallization of a low coefficient of thermal expansion phase. In this work, we produced …

In the IR spectra of the silica and silicate glasses, the shifts of the maximum intensity position
of the νSi–O–Si, as band upon heating or applying mechanical stress could be attributed to …
