Addressing the long-standing limitations of double exponential and non-rectangular hyperbolic models in quantifying light-response of electron transport rates in different photosynthetic organisms under various conditions

open access: yesFrontiers in Plant Science
The models used to describe the light response of electron transport rate in photosynthesis play a crucial role in determining two key parameters i.e., the maximum electron transport rate (Jmax) and the saturation light intensity (Isat). However, not all

Three-dimensional laser cooling at the Doppler limit

open access: yes, 2014
Many predictions of Doppler cooling theory of two-level atoms have never been verified in a three-dimensional geometry, including the celebrated minimum achievable temperature $\hbar \Gamma/2 k_B$, where $\Gamma$ is the transition linewidth.

iSAT: a visual learning analytics tool for instructors

open access: yesResearch and Practice in Technology Enhanced Learning, 2016
Interactive Stratified Attribute Tracking (iSAT) is a visual analytics tool for cohort analysis. In this paper, we show how instructors can use iSAT to visualize transitions of groups of students during teaching-learning activities. Interactive visual analytics gives the instructor the affordance of understanding the dynamics of the class of students ...

In Situ Construction of Cu+‐Ov‐Ce3+ Sites on CeO2 for Efficient NH3 Oxidation

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
An advanced CeCuOx nanorod catalyst is developed via in situ hydrothermal synthesis, and it exhibits remarkable NH3‐SCO activity, N2 selectivity, and stability. The addition of Cu induces the formation of abundant Cu+‐Ov‐Ce3+ active sites on CeO2 and switch the primary intermediate species of NH3 oxidation from bidentate nitrate species to monodentate ...

The structure and age determination of the writings written with ballpoint pen

open access: yesMedicine Science, 2018
Ink age determination is the determination and interpretation of the structure of the ink on a document by using advanced analytical methods. Over time, the dyestuff in the structure of the ink go through demethylation, solvents get evaporated and resins
