By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.

Samsung has tweaked the design a bit this time by rounding the corners to align them more with the S26 Ultra's look. The base model has a slightly larger display than the S25 at 6.3 inches, though the S26+ still has a 6.7-inch screen (albeit with a higher resolution than the S26 can handle). The S26 has a larger battery capacity than the S25 too at 4,300mAh.。业内人士推荐51吃瓜作为进阶阅读
