Impact of the Great Recession on Total Employment and Unemployment Rates in the U.S. [PDF]

open access: yes, 2012
Color poster with text, images, maps, and tables.The economic downturn of 2008-09 was so severe that it has become known as the Great Recession, and by most accounts the subsequent recovery has been relatively slow.

Oxygen Vacancy‐Enriched Platinum Single‐Atom Nanozyme Wrapped in Nanoislands: Unlocking Catalytic Activity and Reprogramming Redox Microenvironment for Osteonecrosis Repair

open access: yesAdvanced Science, EarlyView.
CeO2‐x/Pt single‐atom nano‐island is constructed via low‐temperature reduction, featuring abundant oxygen vacancies and an island–sea structure. It delivers outstanding multi‐enzyme‐mimetic activity and ROS‐scavenging efficiency. Density functional theory reveals optimized electronic structures and reaction pathways.

Detecting recessions in the Great Moderation: a real-time analysis [PDF]

open access: yes
The nature of the business cycle, particularly in the United States, has changed dramatically over the past several decades. In the 1970s and early 1980s, the U.S. economy often whipsawed up and down.

Outlook and appraisal [October 2013] [PDF]

open access: yes, 2013
There is little doubt that after five years since the start of the Great Recession we are now witnessing a stronger recovery, all be it belatedly compared to any recession in the last 70 to 80 years.

Beyond d‐Band Catalysis: A Critical Review and Descriptor Framework for Rare‐Earth Engineering in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework
