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.

ECS hosted its first ever satellite OpenCon event on October 1, 2017 during the 232nd ECS Meeting in National Harbor, MD. This landmark event marked ECS’s first large community effort aimed at creating a culture of change in how research is designed, shared, discussed, and disseminated, with the ultimate goal of making scientific progress faster.

Watch full coverage of the event.

OpenCon is an international event hosted by the Right to Research Coalition, a student organization of SPARC, the Scholarly Publishing and Academic Resources Coalition. OpenCon provides a platform the researchers to learn about open access and open science, develop critical skills, and catalyze action toward a more open system for sharing the world’s information.

This event featured vocal advocates in the open movement, examining the intersection of advances in research infrastructure, the researcher experience, funder mandates and policies, as well as the global shift that is happening in traditional scholarly communications.

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.

Co-organizer David Beck led a hack session during the ECS Data Sciences Hack Day.

The full vibrancy of the electrochemical community was on show during the recent 232nd ECS Meeting in National Harbor, MD. Adding to the diversity of ideas and excitement for electrochemistry were the 30 participants of the inaugural ECS Data Sciences Hack Day on Wednesday, October 4. The participants in the hack day traveled from around the globe and represented varying stages of careers in both academic and industry roles.

The day-long event was kicked off with a short series of informational sessions covering some of the essential tools in any data scientist’s toolbox. During lunch, participants pitched their ideas for projects, and teams for the afternoon session organically formed around common interests. The remaining time during the afternoon was reserved as open “hacking” time for working on the project ideas. Excitingly, good progress was made in this four-hour block with teams working on a wide variety of projects, including:
