Bocoran Tampilan iOS 8 Mulai Beredar
KOMPAS.com - Tak lama setelah update iOS 7.1 dirilis, bocoran mengenai sistem operasi versi berikutnya, iOS 8, mulai bermunculan.
Nilai WeChat Bisa Tiga Kali WhatsApp
KOMPAS.com -Saat WhatsApp resmi dibeli Facebook, banyak yang terkejut dengan total nilai transaksi penjualannya. Walau tak semuanya dibayar dengan uang, namun angka 19 miliar dollar AS menjadi nilai akuisisi tertinggi untuk sebuah layanan pesan instan.
Setelah kabar akuisisi tersebut, banyak analis yang menjadikan WhatsApp sebagai parameter untuk menilai berapa harga yang layak untuk layanan pesan instan lain, termasuk WeChat.
Dikutip dari Techcrunch, lembaga analis Credit Lyonnais Securities Asia (CLSA) menaksir harga WeChat bisa tiga kali lipat dari WhatsApp, nilainya saat ini mencapai setidaknya 60 miliar dollar AS.

Advances in the science and technology of carbon nanotubes and their composites
Since their first observation nearly a decade ago by Iijima (Iijima S. Helical microtubules of graphitic carbon Nature. 1991; 354:56–8), carbon nanotubes have been the focus of considerable research. Numerous investigators have since reported remarkable physical and mechanical properties for this new form of carbon. From unique electronic properties and a thermal conductivity higher than diamond to mechanical properties where the stiffness, strength and resilience exceeds any current material, carbon nanotubes offer tremendous opportunities for the development of fundamentally new material systems. In particular, the exceptional mechanical properties of carbon nanotubes, combined with their low density, offer scope for the development of nanotube-reinforced composite materials. The potential for nanocomposites reinforced with carbon tubes having extraordinary specific stiffness and strength represent tremendous opportunity for application in the 21st century. This paper provides a concise review of recent advances in carbon nanotubes and their composites. We examine the research work reported in the literature on the structure and processing of carbon nanotubes, as well as characterization and property modeling of carbon nanotubes and their composites.\
