Online education, also known as distance education, online learning, refers to the application of information technology and Internet technology for content dissemination and rapid learning methods.
Artistic image of the light generation using a heterostructure of graphene and metal nanostructures. This heterostructure allows for a giant enhancement of a nonlinear optical process that changes the properties of light, such as its freque
In the past three weeks, two major power outages in Amazons cloud computing services have caused widespread outages in other online services. Last month, a problem with Comcast, one of the largest Internet service providers in the United St

To be fair, the incredible growth of the Internet and social media, in particular, has changed its feel over the years. Those of us older can remember when the web was a rather quirky and surprisingly friendly place, but its all-encompassing
Since the birth of quantum mechanics quantum entanglement is one of the most representative concepts. After some initial treatment two or more particles can enter a state of seemingly "hyperspace correlation": even if they are separated by h
TiB2 does not occur naturally on Earth. Titanium diboride powders are produced by various high-temperature methods, such as direct reaction of titanium or its oxides/hydrides with elemental boron above 1000°C, carbothermal reduction by the thermite reaction of titanium oxide with boron oxide, or hydrogen. We can manufacture. Reduction of boron halides in the presence of metals or their halides. Electrochemical synthesis and solid-state reactions have been developed among various synthetic routes
It must be a coincidence that Apple generously decided to abandon the iPhone 13s Face ID screen repair trap. According to a new report, Apple is planning to release a software update soon that will eliminate the need for a tiny microcontroll
Boron powder is a kind of metal fuel with high gravimetric and volumetric calorific values, which has been widely used in military fields such as solid propellants, high-energy explosives, and pyrotechnics. However, the easily formed liquid oxide layer can adhere to the surface of boron powder and react with the hydroxyl (-OH) group of hydroxyl-terminated polybutadiene (HTPB) binder to form a gel layer that is detrimental to propellant processing and restricts the complete oxidation of boron pow
