Um Siliziumbloecke in hauchduenne Wafer zu zersaegen, braucht man das richtige Werkzeug: einen Kilometer langen Draht, benetzt mit einer Art Schleifpaste. Doch muessen alle Parameter optimal angepasst sein - nur so vermeidet man beim Schneiden grosse Materialverluste.
Bringing lively discussions on technologies with life-changing potential, SPIE Optics and Photonics runs through Thursday in the San Diego Convention Center. Approximately 4,500 international attendees are expected to attend the technical presentations and panels, professional development courses, and exhibition.
Researchers have devised a way to encapsulate bacteria in a synthetic polymer hydrogel. These new, stable, bio-hybrid materials maintain the microbes' ability to exchange nutrients and metabolic products with their environment, and could find widespread applications, for example, as biosensors, catalysts, drug-delivery systems, or in wastewater treatment
Researchers have been able to illuminate brain tumors by injecting fluorescent nanoparticles into the bloodstream. The tiny particles can safely cross the blood-brain barrier, an almost impenetrable barrier that protects the brain from infection.
Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor. Now, scientists at the Carnegie Institution in Washington D.C., US, have discovered a hydrogen-based compound that could be helpful in the search for metallic and superconducting forms of hydrogen.
The future of quantum computing depends on engineers being able to develop quantum error-correction codes that allow quantum devices to compute reliably in a world so fragile that information is destroyed or altered as soon as it is measured or read.
UCLA researchers have developed technology to perform more than a thousand chemical reactions at once on a stamp-size, PC-controlled microchip, which could accelerate the identification of potential drug candidates for treating diseases like cancer.
Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations, a group of academic researchers is reporting.
