The development of petroleum exploration has led to an increased focus on deeper drilling, necessitating more robust materials with enhanced properties. In this context, sapphire glass materials are emerging as a novel alternative solution.

Although sapphire glass boasts high hardness and good abrasion resistance, it still possesses brittleness and is prone to breakage when exposed to intense impact. Hence, when designing products incorporating sapphire glass, it is necessary to mitigate the risk of fragmentation through structural design optimization and other protective measures to guarantee that the properties of sapphire...

Sapphire bullet-proof technology is one of the challenging high-tech fields that can offer valuable resources and assistance to police, military, and security agencies. Whether in counter-terrorism, protecting important individuals, or safeguarding crucial national infrastructure, sapphire bulletproof technology plays an irreplaceable and significant role.

Although certain studies indicate that blue light may have an impact on ocular health, there is currently no definitive scientific evidence substantiating the claim that blue light filtering lenses can prevent or treat eye diseases. Nevertheless, individuals who engage in prolonged use of electronic devices or those with pre-existing ocular conditions may still derive...
