Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

open access: yesAdvanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

open access: yesAdvanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Does nitrogen uptake affect nitrogen uptake efficiency, or vice versa?

Acta Physiologiae Plantarum, 2008
The aim of the paper is to enter into a discussion concerning the title question. In our opinion it is N uptake efficiency that affects N uptake, but not vice versa, mainly because the former is a genotypic characteristic, and as such is not influenced by N uptake.

Effect on nitrogen and spacing on the yield of sugarcane and uptake of nitrogen

Madras Agricultural Journal, 2023
A field experiment was conducted at Sugarcane Breeding Institute, Coimbatore during 1993-94 to study the effect of graded levels of N application (0, 100, 200, 300 and 400 kg ha) under two different row spacings (75 and 90 cm) in three promising midlate varieties of sugarcane (Co 86027, Co 86032 and Co 86038) on the nitrogen uptake, cane yield and ...

EFFECT OF NITROGEN AVAILABILITY ON GROWTH AND NITROGEN UPTAKE IN LETTUCE

Acta Horticulturae, 2000
Fresh and dry matter production and nitrogen uptake during crop growth of two lettuce (Lactuca sativa L.) cultivars, cv. Audran (butterhead lettuce) and cv. Canasta (loose leaf lettuce), were studied in a field trial at different levels of fertilizer-N (0, 50, 100 and 200 kg N ha-1) broadcast at transplanting. On a dry matter basis, the relative growth

Dissolved organic nitrogen uptake by seagrasses

Limnology and Oceanography, 2008
We examined the ability of seagrasses to take up dissolved organic nitrogen (DON) with leaves (in situ) and roots (laboratory) in an oligotrophic tropical offshore meadow in Indonesia using 15N‐labeled nitrogen (N) substrates. We compared the uptake of urea and amino acids with that of ammonium (NH4+) and nitrate (NO3−) and determined uptake kinetics ...
