Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Energy Profiles of Activated Sludge Degradation of a Xenobiotic Compound

open access: yesChemical Engineering Transactions, 2015
Stable structure of xenobiotic requires a large amount of energy for the microorganisms to metabolize. In addition to the general hard-to-treat nature of a xenobiotic, the energy expense in breaking xenobiotic structure may add to the difficulty of ...

Influence of Rice Production on the Quality of Water in Tailwater Collection Reservoirs [PDF]

open access: yes, 1996
Since maintaining high water quality standards in the state remains a high priority, monitoring for pesticides in water sources must continue. Determining the type, concentration, and characteristics of any pesticides present in water supplies are ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

open access: yesAdvanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

CIPC-2,4-D Combinations for Control of 2,4-D-Resistant Monocot Species

open access: yes, 1970
Laboratory, greenhouse and field studies show that CIPC pretreatments alter 2,4-D resistant monocot species making them susceptible to subsequent 2,4-D treatments. Pretreatment with 1 lb/A CIPC followed 1- several weeks later by 1 lb/A 2,4-D has given control of wild garlic (Allium vineale) and eradication of yellow nutsedge (Cyperus esculentus) along ...

The natural ways of degradation of pesticides based on 2,4-dichlorophenoxyacetic acid [PDF]

open access: yes, 2016
To increase crop yields by destroying weeds the separate group of pesticides exist, that is called herbicides. Among the herbicides based on chlorphen oxalcanecarboxylic acids products of sodium and ammonium salts, as well as 2,4-dichlorophenoxyacetic ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

open access: yesAdvanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Involvement of several transcriptional regulators in the differential expression of tfd genes in Cupriavidus necator JMP134 [PDF]

open access: yes, 2009
Cupriavidus necator JMP134 has been extensively studied because of its ability to degrade chloroaromatic compounds, including the herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and 3-chlorobenzoic acid (3-CB), which is achieved through the pJP4 ...

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...
