Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

open access: yesAdvanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Effects of olive oil and its fractions on oxidative stress and the liver's fatty acid composition in 2,4-Dichlorophenoxyacetic acid-treated rats

open access: yesNutrition & Metabolism, 2010
Background Olive oil's beneficial effects are not only related to its high content of oleic acid, but also to the antioxidant potential of its polyphenols.

Ultra‐Improved Interfacial Strength Between Metallic Surface and Polyurethane via Cost‐Effective Anodizing Process

open access: yesAdvanced Materials Interfaces, EarlyView.
SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

Study of 2,4-D Spectral Characteristics and Its Detection in Zizania Latifolia Using Terahertz Time-Domain Spectroscopy

open access: yesApplied Sciences, 2019
2,4-Dichlorophenoxyacetic acid (2,4-D) is a common plant growth regulator, which can remain in food and, with long-term consumption, threaten human health. Therefore, it is necessary to propose an effective detection method.

Generación in situ de especies oxidantes para la remoción del herbicida 2,4-D en medio acuoso [PDF]

open access: yes, 2012
En el presente estudio, se llevó a cabo la generación de especies fuertemente oxidantes: los radicales hidroxilo (HO•) y el ion ferrato [FeO4 2-] para la descomposición del ácido 2,4-diclorofenoxiacético (2,4-D), un herbicida recalcitrante.

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

open access: yesAdvanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.

Gibberellic acid and 2,4-D as growth regulators in laboratory culture of seaweeds [PDF]

open access: yes, 1999
The growth regulatory effects of gibberellic acid (GA) and 2,4-D (2,4-dichlorophenoxy acetic acid) on a green alga, Ulva fasciata and two species of red algae, Gracilaria corlicata and Hypnea valentiae were studied.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

open access: yesAdvanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

REGENERATION OF Agave marmorata Roezl PLANTS, BY SOMATIC EMBRIOGENESIS

open access: yesTropical and Subtropical Agroecosystems, 2020
Background. Agave marmorata Roezl is a monocot plant of the Asparagaceae family, which is mainly used in the elaboration of the alcoholic drink called mezcal. This species is propagated by seeds or stolons (hijuelos), but its reproduction is slow because

OZONOLISIS UNTUK DEGRADASI ASAM 2,4-IKLOROFENOKSIASETAT(2,4-D) DALAM PESTISIDA SANTAMIN 865 SL [PDF]

open access: yes, 2011
One of the herbicides that used in more grade is 2,4-dichlorophenoxyacetic acid (2,4-D). It is well known as inexpensive herbicides, but it can give rise to undesirable pollution.
