Invisibility cloakInvisibility cloak closer to reality: Concealing military airplanes, and even people
Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, acoustic, and other types of waves in ways not possible in nature. Now, Hao Xin, a professor of electrical and computer engineering at the University of Arizona, has made a discovery with these synthetic materials that may take engineers one step closer to building microscopes with superlenses that see molecular-level details, or shields that conceal military airplanes and even people.

EnergyNovel nanosized antenna arrays key to effective harvesting of solar energy
For years, scientists have studied the potential benefits of a new branch of solar energy technology that relies on incredibly small nanosized antenna arrays that are theoretically capable of harvesting more than 70 percent of the sun’s electromagnetic radiation and simultaneously converting it into usable electric power. A novel fabrication technique could provide the breakthrough technology scientists have been looking for to improve today’s solar energy systems.

Invisibility cloaksNew invisibility cloak conceals objects from human view
For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans; the new “carpet cloak” works by concealing an object under layers of silicon oxide and silicon nitride etched in a special pattern, and bending light waves away from the bump that the object makes, so that the cloak appears flat and smooth like a normal mirror

China syndromeChina establishes itself as a physics powerhouse
Published journal articles in nanoscience, with at least one co-author based in China, have seen a 10-fold increase since the beginning of the millennium, rising to more than 10,500 in 2007; China has already overtaken the United Kingdom and Germany in the number of physics papers published and is beginning to nip at the heels of the United States; the verdict on the quality of many of these papers is still out
