$Graphjet Technology (GTI.US)$ 石墨烯目前是世上最薄卻也是最堅硬的納米材料[6]，它幾乎是完全透明的，只吸收2.3%的光[7]；導熱係數高達5,300 W/(m·K)，高於納米碳管和金剛石，常溫下其電子遷移率超過15,000 cm2/(V·s)，又比納米碳管或硅晶體（monocrystalline silicon）高，而電阻率只約10-6 Ω·cm，比銅或銀更低，爲目前世上電阻率最小的材料[8][4]。由於它的電阻率極低，電子的移動速度極快，因此被期待可用來發展出更薄、導電速度更快的新一代電子器件或晶體管。石墨烯實質上是一種透明、良好的導體，也適合用來製造透明觸控螢幕、光板，甚至是太陽能電池。

聯邦開放市場委員會計劃於 7 月 30 日至 31 日召開即將舉行的會議。廣泛預期該委員會將將聯邦基金利率保持在 5.25％ 和 5.50％ 之間。在兩天的會議結束後，聲明將於美國時間 14:00 發布，接著將與傑羅姆鮑威爾主席舉行新聞發布會，預定於美國東部 14:30。
