The ECS Lecture during the 232nd ECS Meeting in National Harbor, MD, was delivered by Steven Chu. Chu is currently the William R. Kenan, Jr., Professor of Physics and Professor of Molecular & Cellular Physiology at Stanford. Previously, he served as U.S. Secretary of Energy under President Obama and was the co-recipient of the 1997 Nobel Prize in Physics for his contribution to laser cooling and atom trapping.

Chu’s ECS Lecture, “The Role of Electrochemistry in our Transition to Sustainable Energy,” focused on the risks society is facing due to changing climate, the evolving energy landscape, and the role of electrochemistry in providing critical technological advances.

During his lecture, Chu outlined the risks that modern society faces, which demand technological innovation to provide solutions. Namely, Chu stated that the rising climate poses significant risks to the global community. According to Chu, the Earth has warmed by an alarming one degree Celsius since 1975.

“One degree Celsius does not sound like a lot, but just a couple of degrees warmer would make a dramatic difference,” Chu said. “If the Earth does warm by two degrees Celsius, Boston will be underwater.”

After remaining steady for three years, global fossil fuel emissions are rising again and may increase again next year. But improved energy efficiency and a booming renewables market may offer a bit of a silver lining.

“This year’s result is discouraging, but I remain hopeful,” says Rob Jackson, professor at the School of Earth, Energy & Environmental Sciences at Stanford University and chair of the Global Carbon Project, which released a series of reports in Environmental Research Letters.

“In the US, cities, states, and companies have seized leadership on energy efficiency and low-carbon renewables that the federal government has abdicated.”

The report appears with data published simultaneously in an Earth System Science Data Discussions paper led by Corinne Le Quéré of the University of East Anglia, who is also part of the Global Carbon Project.

Together, they forecast that global fossil fuel emissions will reach a record 37 billion tons of carbon dioxide in 2017, with total emissions reaching a record 41 billion tons, including deforestation. Atmospheric carbon dioxide concentration reached 403 parts per million in 2016, and is expected to increase by 2.5 parts per million in 2017.

A reversible fabric keeps skin a comfortable temperature whatever the weather—and could save energy by keeping us away from the thermostat.

As reported in Science Advances, the double-sided fabric is based on the same material as everyday kitchen wrap and can offer warmth or cooling depending on which side faces out.

“Why do you need to cool and heat the whole building? Why don’t you cool and heat individual people?” says Yi Cui, professor of materials science and engineering at Stanford University, who thought if people could be more comfortable in a range of temperatures, they could save energy on air conditioning and central heating.

Thirteen percent of all of the energy consumed in the United States is due to indoor temperature control. But for every 1 degree Celsius (1.8 degrees Fahrenheit) that a thermostat is turned down, a building can save a whopping 10 percent of its heating energy—and the reverse is true for cooling. So adjusting temperature controls by just a few degrees could have major effects on energy consumption.

Researchers have developed a type of “smart paper” that can conduct electricity and detect water.

The paper, laced with conductive nanomaterials, can be employed as a switch, turning on or off an LED light, or as an alarm system indicating the absence or presence of water.

In cities and large-scale manufacturing plants, a water leak in a complicated network of pipes can take tremendous time and effort to detect, as technicians must disassemble many pieces to locate the problem.

The American Water Works Association indicates that nearly a quarter-million water line breaks occur each year in the United States, costing public water utilities about $2.8 billion annually.

The smart paper could simplify the process for discovering detrimental leaks.

Symposium E01: Electrodeposition of Micro and Nano Materials for Batteries and Sensors

Symposium Focus: This symposium will cover advances in electrochemical deposition (electrolytic, electroless, chemical bath or electrochemical ALD) for energy storage and sensor devices. The electronics industry has demonstrated electrochemical processing at micro and nano dimensions for interconnect, barrier layer, magnetics and solder applications for metals, alloys and composites. A large number of relevant active materials and current collector scaffolds can also be deposited, structured and post-processed electrochemically for use in advanced batteries and sensor devices. These processes can enable future micro-devices for the internet of things but equally can address improvements in certain components for large capacity batteries, electrolyzers or fuel cells. Our symposium welcomes also papers covering vapor deposition techniques such as ALD which can be used in combination with the wet chemical deposition routes for the fabrication of microdevices.

Scientists these days face a conundrum. As Americans are buffeted by accounts of fake news, alternative facts and deceptive social media campaigns, how can researchers and their scientific expertise contribute meaningfully to the conversation?

There is a common perception that science is a matter of hard facts and that it can and should remain insulated from the social and political interests that permeate the rest of society. Nevertheless, many historians, philosophers and sociologists who study the practice of science have come to the conclusion that trying to kick values out of science risks throwing the baby out with the bathwater.

Ethical and social values – like the desire to promote economic development, public health or environmental protection – often play integral roles in scientific research. By acknowledging this, scientists might seem to give away their authority as a defense against the flood of misleading, inaccurate information that surrounds us. But I argue in my book “A Tapestry of Values: An Introduction to Values in Science” that if scientists take appropriate steps to manage and communicate about their values, they can promote a more realistic view of science as both value-laden and reliable.

New research sheds light on the effectiveness and value of carbon-pricing incentive programs.

In a new paper, based on analysis of a 2015 pilot program on the Yale University campus, researchers examine internal carbon-pricing strategies, including different models of implementation.

Further, they illustrate how the Yale project, which has since expanded into a campus-wide initiative, has provided empirical evidence of the effectiveness of these price signals.

More than 600 major companies—from BP to Microsoft—have adopted carbon-pricing programs to spur energy conservation and control their carbon emissions. But researchers have previously not analyzed or publicly reported the effectiveness of these efforts.
