An oligo peptide transporter family member, OsOPT7, mediates xylem unloading of Fe for its preferential distribution in rice

New Phytologist, Volume 242, Issue 6, Page 2620-2634, June 2024.
Summary Iron (Fe) needs to be delivered to different organs and tissues of above‐ground parts for playing its multiple physiological functions once it is taken up by the roots. However, the mechanisms underlying Fe distribution are poorly understood.

Enrichment of 54Fe by Electromagnetic Isotope Separator (EMIS) [PDF]

مجله علوم و فنون هسته‌ای, 2014
Electromagnetic Isotopes Separator (EMIS) has been installed in Karaj since 1991 in order to separate isotopes of a wide range of elements. Iron is successfully separated. Iron element has four stable isotopes, 58Fe, 57Fe, 56Fe and 54Fe.

Promoting effects of aluminum addition on chlorophyll biosynthesis and growth of two cultured iron‐limited marine diatoms

Limnology and Oceanography, Volume 69, Issue 5, Page 1157-1171, May 2024.
Abstract Aluminum (Al) may play a role in the ocean's capacity for absorbing atmospheric CO2 via influencing carbon fixation, export, and sequestration. Aluminum fertilization, especially in iron (Fe)‐limited high‐nutrient, low‐chlorophyll ocean regions, has been proposed as a potential CO2 removal strategy to mitigate global warming.

Characterization of a Southern Ocean deep chlorophyll maximum: Response of phytoplankton to light, iron, and manganese enrichment

Limnology and Oceanography Letters, Volume 9, Issue 2, Page 145-154, April 2024.
Abstract Southern Ocean phytoplankton growth is limited by low iron (Fe) supply and irradiance, impacting the strength of the biological carbon pump. Unfavorable upper ocean conditions, such as low nutrient concentrations, can lead to the formation of deep chlorophyll or biomass maxima (DCM/DBM).

Thermodynamically Guided Improvement of Fe–Mn–Al–Ni Shape‐Memory Alloys

Advanced Materials, Volume 36, Issue 5, February 1, 2024.
The utilization of a microstructural‐informed thermodynamic model enables the creation of pseudoelastic Fe–Mn–Al–Ni shape‐memory alloys with enhanced reversibility. The feasibility of the proposed alloy‐design strategy is proven by complementary spherical nanoindentation and in situ compression tests.
