Researchers are working to harness solar power more effectively, creating energy-efficient and durable light sources. The project aims to produce low-cost solar cells using printing techniques, with recent results showing promising 3% power conversion efficiency.
The three-year project aims to develop cost-effective, reel-to-reel printable plastic solar cells that can be printed like money. The technology has enormous potential for the solar industry in Australia and could lead to a world-leading Australian industry in printable electronics.
The project makes available the original serial parts of Dickens' 15 novels, including Oliver Twist and A Tale of Two Cities, through the Web. The digitized works are expected to increase awareness for Dickens' mastery of the serial form and his impact on mass-market publication.
Researchers from Northwestern University have successfully mass-produced the 2008 Summer Olympics logo, 15,000 times, using a new printing technique called Polymer Pen Lithography (PPL). The PPL method allows for fast, inexpensive, and simple printing on nanometer, micrometer, and millimeter length scales.
Scientists have created the world's first all-integrated sensor circuit based on nanowire arrays, combining light sensors and electronics made of different crystalline materials. The method can be used to reproduce numerous devices with high uniformity.
Chemical engineers at Princeton University developed a method for shooting stable jets of electrically charged liquids from a wide nozzle, producing lines just 100 nanometers wide. This technique offers better resolution than ink-jet printing and far more speed and ease than conventional nanotechnology.
Researchers at MIT have developed an electronic nose that can detect hazardous gases like carbon monoxide and explosives using a novel inkjet printing method. The sensor, which consists of thin layers of hollow spheres made of barium carbonate, has the potential to be mass-produced for widespread use.
A University of Missouri-Columbia research team has developed a biology-based process for printing organ tissue structures, maintaining cell properties and allowing nature to take over. The breakthrough enables the creation of functional tissue structures without needing to control cell location or function.
The team's new e-jet printing process can produce lines as narrow as 700 nanometers and dots as small as 250 nanometers using electrically induced fluid flow and nanoscale nozzles. This technology has potential applications in large-area circuits, displays, photovoltaic modules, security, biotechnology, and photonics.
A new microcontact insertion printing technique builds surfaces with specific functions inserted at known intervals, enabling analysis of biochemical mixtures and molecular-scale electronic components. The process allows for precise placement of isolated molecules in a predesigned nano-scale or micro-scale pattern.
Researchers print carbon nanotubes on paper and plastic surfaces, creating conductive patterns that could be used in flexible electronics, sensors, and other applications. The approach is simple, versatile, and inexpensive, making it a potential alternative to current methods.
Researchers at the University of Utah are developing a hydrogel that helps grow new tissue for repairing diseased organs. The gelatin-like substance, made from sugar chains, is essential for organ printing, which aims to print living, three-dimensional tissue for transplantation.
The Newman team won an NSF award for their work on biological self-assembly, a principle that considers the physical properties of cells and tissues to develop new organs. Their research could lead to the 'printing' of replacement parts using organ printing, revolutionizing organ transplantation.
Researchers at Penn State have developed a new microprinting technique called microdisplacement printing, which enables precise placement of molecules during nanoscale component fabrication. This method relaxes requirements for positioning stamps used to apply consecutive patterns with different molecular inks.
A new printing method called Supramolecular Nano-Stamping (SuNS) enables the mass production of complex nano-scale patterns, including DNA microarrays. This could revolutionize diagnostics by making DNA analysis routine and inexpensive.
A Dutch anthropologist's doctoral research on female health workers in Yemen reveals the challenges they face despite their contributions to the healthcare system. The translated thesis provides insight into the backgrounds and motivations of these women, as well as the different agendas and interests at play.
The Internet has led to a renaissance in informal writing, with online diaries and blogs increasing expressive range. Professor Crystal argues that concerns about language deterioration are misplaced, as new technology has increased informality in writing.
A new five-year project at NIST seeks to create standardized measurement methods and diagnostic probes for organic electronics. The goal is to accelerate the development of practical plastic microchips, which could enable large-area applications like wall-sized electronic murals.
Researchers at Purdue University developed a method to trace documents to specific printers, enabling law enforcement to investigate counterfeiting and homeland security matters. The technique uses unique printer characteristics and embedded features to identify the printer used to create documents.
Researchers at University of Illinois have developed a technique to print single-crystal silicon objects onto flexible plastics, enabling high-performance thin-film transistors. This approach separates silicon processing from component fabrication, allowing for integration with various materials and large-area formats.
Scientists create novel processing methods for producing organic conducting polymer circuits, leveraging micro contact printing for low-cost, adaptable, and fast production.
