Direct radiative effect of the Russian wildfires and its impact on air temperature and atmospheric dynamics during August 2010

open access: yes, 2013
In this study, we investigate the shortwave aerosol direct radiative forcing (ADRF) and its feedback on air temperature and atmospheric dynamics during a major fire event that occurred in Russia during August 2010.

Optical Hydrogen Sensing Materials for Applications at Sub‐Zero Temperatures

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the viability of optical hydrogen sensors at temperatures as low as −60°C. Using advanced metal hydride materials, the sensors detect hydrogen with high sensitivity, speed, and stability across a wide range of concentrations. These findings open doors for safe hydrogen detection in extreme cold, enabling applications in aviation,

Internal climate variability and projected future regional steric and dynamic sea level rise

open access: yesNature Communications, 2018
As the global climate becomes warmer, the associated rising sea level could pose significant threats to island and coastal communities. Here the authors show that internal climate variability plays a key role in determining this sea level rise ...

Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Atmospheric dynamics in RR Lyrae stars - The Blazhko effect

open access: yes, 2013
Context. Discovered in 1907, the Blazhko effect is a modulation of the light variations of about half of the RR Lyr stars. It has remained unexplained for over 100 years, despite more than a dozen proposed explanations.

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti‐6Al‐4V

open access: yesAdvanced Functional Materials, EarlyView.
This research applies advanced laser beam shaping (LCoS‐SLM) to fabricate the Ti‐6Al‐4V alloy via laser powder bed fusion. A tailored beam is used to prevent martensite formation and create a dual α+β microstructure by controlling cooling rates.

Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.
