New Material Captures Carbon at Half the Energy Cost

Capturing carbon from power plants is likely in the future to avoid the worst effects of climate change, but current technologies are very expensive. A new material, a diamine-appended metal-organic framework, captures and releases CO2 with much reduced energy costs compared to today’s technologies, potentially lowering the cost of capturing this greenhouse gas.

Warmer, drier climate altering forests statewide

Historical California vegetation data that more than once dodged the dumpster have now proved their true value, documenting that a changing forest structure seen in the Sierra Nevada has actually happened statewide over the past 90 years.

Solving an Organic Semiconductor Mystery

Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative to silicon-based devices. Uneven performances, however, have been a persistent problem. That’s now changed.

Tropical paradise inspires virtual ecology lab

An international collaboration including Neil Davies, Director of UC Berkeley's Gump Station, is preparing to create a digital representation of of the Pacific island of Moorea to create a virtual lab to test and hypothesize the impact of human activities. 

From the Bottom Up: Manipulating Nanoribbons at the Molecular Level

Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties—such as position-dependent, tunable bandgaps—that are potentially very useful for next-generation electronic circuitry.

New Discovery Opens Door for Radical Reduction in Energy Consumed by Digital Devices

A new study led by engineers at UC Berkeley and CITRIS describes the first direct observation of a long-hypothesized but elusive phenomenon called “negative capacitance.” The work describes a unique reaction of electrical charge to applied voltage in a ferroelectric material that could open the door to a radical reduction in the power consumed by transistors and the devices containing them.

Lightning Expected to Increase by 50 Percent with Global Warming

Today’s climate models predict a 50 percent increase in lightning strikes across the US during this century as a result of warming temperatures associated with climate change. UC Berkeley climate scientists look at predictions of precipitation and cloud buoyancy in 11 different climate models and conclude that their combined effect will generate more frequent electrical discharges to the ground.

Tobacco Gets a Makeover as New Source for Biofuel

Peggy Lemaux, UC Berkeley cooperative extension specialist, is working with Berkeley Lab and the University of Kentucky to develop a genetically engineered tobacco plant that will produce oil that can be used as a biofuel. KQED Science wrote this story about the research effort.
