Led by the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville, a study of a solar-energy material with a bright future revealed a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat.
“We showed that the thermal transport and charge-carrier cooling time can be manipulated by changing the mass of hydrogen atoms in a photovoltaic material,” said ORNL’s Michael Manley. “This route for extending the lifetime of charge carriers bares new strategies for achieving record solar-to-electric conversion efficiency in novel hot-carrier solar cells.”
UT’s Mahshid Ahmadi noted, “Tuning the organic-molecule dynamics can enable control of phonons important to thermal conductivity in organometallic perovskites.” These semiconducting materials are promising for photovoltaic applications.
AHA and other organizations representing the nation’s clinicians, hospitals, health systems and experts in health informatics and health information management today urged the Department of Health and Human Services’ Office of the National Coordinator for Health Information Technology to allow for at least one year of extended enforcement discretion for its information blocking rule.
“We write to express our steadfast commitment to furthering patient access to their medical records via apps, leveraging application programming interfaces (APIs), enhancing clinician and providers’ access to data within their workflow, and securely sharing medical information electronically so patients and clinicians make informed treatment decisions,” the coalition wrote. “… However, the COVID-19 pandemic continues to monopolize our members’ time and attention, and has strained resources, drastically limiting our members’ ability to prepare for the November 2nd information blocking deadline.”
The coalition also urged the agency to work with the Centers for Medicare & Medicaid
In March, the Department of Health and Human Services passed sweeping interoperability rules that would add teeth to requirements for healthcare providers and IT vendors to securely share patient health information. With the initial deadline approaching in November, is HHS facing pressure to push the deadline back?
“We’ve had lobbying pressure all along,” Dr. Don Rucker, National Coordinator for Health Information Technology, said in a Thursday panel at CBInsights. “These are all powerful economic forces. Whenever you disrupt powerful economic forces in D.C., the town business is lobbying.”
Recent lobbying disclosure reports confirm Rucker’s comments. Health IT companies paid lobbyists in the second quarter of 2020 related to interoperability and information blocking rules. D.C.-based lobbying firm Mehlman Castagnetti Rosen & Thomas, received $60,000 from Epic Systems, and athenahealth reported spending $60,000 on its own lobbying efforts.
Several other familiar names in healthcare spent lobbying dollars related to information blocking in
