Strain- and System-Specific Enhancement of Artemisinin in Artemisia annua Composite Plants Grown in Hydroponic and Aeroponic Systems

Horticulturae
Efficient production of artemisinin, a valuable secondary metabolite from Artemisia annua, remains a challenge for pharmaceutical applications. This study investigated the use of ex vitro composite plants—generated by inoculation with Agrobacterium ...

Potato Stolon and Tuber Growth Influenced by Nitrogen Form

Plant Production Science, 2014
Potato tuber initiation and its growth are key processes determining tuber yield, which are closely related to stolon growth, and are influenced by many factors including N nutrition.

Effects of ageing and cultivation of grassland on soil nitrogen [PDF]

, 2001
Nitrogen losses from agriculture in the Netherlands have to be strongly decreased because of national and international policy (e.g. Nitrate Directive). The cultivation of grassland when grassland is renewed or converted into arable land may enhance net ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Nitrogen Fertilizer Formulations Modulate the Yield–Cadmium Trade-Off in Rice Through Rhizosphere Processes and Translocation Nodes

Plants
Cadmium (Cd) contamination in paddy soils represents a major risk to global food security and human health because Cd can readily enter the food chain through rice consumption.

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Leaf-root trait relationships in Fabaceae and Poaceae forage species under contrasting nitrogen addition forms and levels

Frontiers in Plant Science
IntroductionNitrogen enrichment can reshape above- and belowground traits, but it remains unclear whether N form and supply level alter leaf-root coordination and whether such coordination is related to biomass.

Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

Advanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.
