Scientists at Living Ink Technologies (Denver, Colo.; www.livinginktechnologies.com) have developed biodegradeable printing ink made from natural cyanobacteria and algae as a sustainable and non-toxic alternative to conventional petroleum-derived printing inks. Living Ink’s method involves using sunlight and carbon dioxide to…
A suitable catalyst for splitting water to make hydrogen must exhibit high H2-conversion efficiency, excellent durability, and must operate well under low voltage. For an efficient H2-evolution reaction, the catalyst must be able to trigger proton reduction with minimal overpotential…
A glassy solid-state electrolyte (SSE) developed by researchers from the University of Texas at Austin (UT; www.utexas.edu) will aid in the evolution of safer, longer-lasting rechargeable batteries. A major concern with the use of lithium- and sodium-ion batteries is the…
A pilot project set up by the University of California Davis (UC Davis; Davis, Calif.; www.ucdavis.edu), GE Water & Process Technologies (Trevose, Pa.; www.gewater.com) and wine-industry service provider Winesecrets LLC (www.winesecrets.com) seeks to capture rainwater for use in wine production,…
When compared to traditional refrigeration cycles, Peltier (thermoelectric) technology has many benefits, including no moving parts and no hazardous refrigerant chemicals. However, it has not yet been widely adopted into large-scale industrial processes (due to poor efficiency, inability to scale…
Scientists at Oregon State University (Corvallis; www.oregonstate.edu) have for the first time demonstrated the use of hydronium ions (H3O+) as charge carriers. The research opens another avenue of exploration for high-power, sustainable batteries for stationary power-storage applications. The research team,…
Porometric mesh is a new weave mesh designed by GKD-USA, Inc. (Cambridge, Md.; www.gkdusa.com) using computational fluid dynamics (CFD) simulations (photo), in a study aimed at reducing erosion and abrasion caused by sand in oil-and-gas pipelines. Porometric mesh has a…
An international team of scientists, led by senior researcher Anna Rising and professor Jan Johansson at the Swedish University of Agricultural Sciences and the Karolinska Institute (both Stockholm, Sweden; www.slu.se and www.ki.se), has developed a process that makes it possible…
A new solution-based method for introducing doping into organic semiconductor films could simplify the manufacture of efficient single-layer photovoltaic cells and move them closer to a commercial reality. Beyond solar cells, the doping technique could be more broadly used in…
So far, there is no high-level evaluation that gives a simple guideline on the benefits and feasibility of converting a batch to a continuous process. Now a group from the Agency for Science, Technology and Research (A*STAR; Singapore; www.ices.a-star.edu.sg) has…
