Zhang, Haibin published the artcileColloidal self-assembly based all-metal metasurface absorbers to achieve broadband, polarization-independent light absorption at UV-Vis frequencies, HPLC of Formula: 111-29-5, the publication is Applied Surface Science (2022), 152624, database is CAplus.

Here, we demonstrate a straightforward colloidal self-assembly strategy to fabricate metasurface absorbers (MAs) with efficient broadband light absorption from UV to visible (Vis) spectral range. In this study, high-index faceted colloidal Au nanocrystals (NCs), i.e., Au icosidodecahedron with active surface plasmonic modes, are innovatively designed as the meta-atoms, while a facile electrostatic self-assembly progress is implemented to arrange these meta-atoms onto a gold reflecting film, resulting in MAs with all-metal structures. Optical characterizations show that the well-designed MAs with a 28-32% surface coverage of Au meta-atoms exhibit an average light absorption above 94% within the wavelengths ranging from 200 to 600 nm. Moreover, the particular absorption behaviors of the designed MAs are inherently polarization-independent for a broad range of incident angles (0-45°) owing to the ultrathin structure and topol. symmetry of the devices. It has been inferred that the pos. localized surface plasmon and gap plasmon resonances excited from the adjacent Au meta-atoms and gold film are critical for self-assembled MAs with excellent absorbing performances. Overall, this work provide an alternative and simple pathway for the construction of scalable and practical UV-Vis MAs, which may facilitate the high-frequency optical applications of thermophotovoltaics, photoelec. devices and photochem. systems.

Li, Qinghua published the artcile¹⁹F magnetic resonance imaging enabled real-time, non-invasive and precise localization and quantification of the degradation rate of hydrogel scaffolds in vivo, Name: 3,3,3-Trifluoropropan-1-ol, the publication is Biomaterials Science (2020), 8(12), 3301-3309, database is CAplus and MEDLINE.

The degradation behavior of hydrogel scaffolds is closely related to the controlled release of bioactive agents and matching with the proliferative demands of newly generated tissues. Here, for the first time, we presented the use of ¹⁹F magnetic resonance imaging (¹⁹F MRI) to precisely monitor the localization and quantify the degradation rate of implantable or injectable hydrogels in a real-time and noninvasive manner, with no interference of endogenous background signals and limitation of penetration depth. The total voxel and content in the region of interest (ROI) were linearly correlated to the injection amount, providing exact 3D stereoscopic and 2D anatomical information in the meantime. Moreover, a computational algorithm was established to present the real-time degradation rate in vivo as a function of time, which was implemented directly from the ¹⁹F MRI dataset. In addition, labeling with a zwitterionic ¹⁹F contrast agent demonstrated a facile and general applicability for multiple types of materials with no influence on their original gelation properties as well as ¹⁹F NMR properties in the hydrogel matrix. Therefore, this ¹⁹F MRI method offers a new approach to non-invasively track the degradation rate of hydrogel scaffolds in vivo in a precise localization and accurate quantification way, which will suffice the need for the evaluation of implants at deep depths in large animals or human objects.

De Mol, Eva published the artcileEPI-001, A Compound Active against Castration-Resistant Prostate Cancer, Targets Transactivation Unit 5 of the Androgen Receptor, COA of Formula: C3H6O2, the publication is ACS Chemical Biology (2016), 11(9), 2499-2505, database is CAplus and MEDLINE.

Castration-resistant prostate cancer is the lethal condition suffered by prostate cancer patients that become refractory to androgen deprivation therapy. EPI-001 is a recently identified compound active against this condition that modulates the activity of the androgen receptor, a nuclear receptor that is essential for disease progression. The mechanism by which this compound exerts its inhibitory activity is however not yet fully understood. Here we show, by using high resolution solution NMR spectroscopy, that EPI-001 selectively interacts with a partially folded region of the transactivation domain of the androgen receptor, known as transactivation unit 5, that is key for the ability of prostate cells to proliferate in the absence of androgens, a distinctive feature of castration-resistant prostate cancer. Our results can contribute to the development of more potent and less toxic novel androgen receptor antagonists for treating this disease.

Koester, Roland published the artcileBoron compounds. XXIX. Catalyzed diethylborylation of alcohols and phenols, Product Details of C4H7BrO, the publication is Justus Liebigs Annalen der Chemie (1975), 352-72, database is CAplus.

The elimination of 1 Et group as ethane from Et3B below 80° by ROH or dihydroxy organic compounds with Me3CCO2BEt2 as catalyst gave Et2BOR (R = Me, Et, Bu, allyl, propargyl, naphthyl, etc.) and (Et2BO)2X (X = CH2CH2, (CH2)5, CH2CCCH2, 1,2-, 1,3-, 1,4-cyclohexanediyl, etc.). Other trialkylboranes react more slowly than Et3B, the rates decreasing: BEt3 > BPr3 > B(CHMe2)3 > B(CH2CHMe2)3. Borylations with BMe3 are very slow and do not proceed uniformly. Alkyl pivalates, pivalonitrile, and other derivatives of pivalic acid and derivatives of other carboxylic acids are less active as catalysts; the catalyzed diethylborylations of hydroxy compounds containing C:C or CC bonds, halogens, carboxylate and aromatic nitro groups all proceed without side reactions. The catalytic diethylborylation is effective for the quant. determination of hydroxy groups in alcs.

Excited state intramol. proton transfer (ESIPT) is a widespread phenomenon that has been exploited in several anal. and technol. applications. Here we describe the synthesis of two ESIPT-active halogen-substituted naphthol-oxazolines that can be conveniently functionalized to develop tailored sensors, and a bis-oxazoline that showcases the potential of oxazolines to undergo double ESIPT. The photophys. properties of these compounds in solution were investigated using polar aprotic solvents and the results were rationalized using DFT/TD-DFT calculations

We report the synthesis and properties of π-stacked polymers consisting of oligothiophene and naphthalene as the stacked π-system and the scaffold, resp. The titled polymers were obtained by the Suzuki-Miyaura coupling reaction. Oligothiophene units were layered in proximity, ∼3.0 Å from each other. Contribution of the quinoidal structure of the oligothiophene units involving the naphthalene scaffolds in the excited state resulted in relatively high photoluminescence quantum efficiencies. The polymers have potential application to optoelectronic devices such as hole-transporting materials. Polymer Journal (2010) 42, 928-934; doi:10.1038/pj.2010.101; published online 27 Oct. 2010.

We synthesized xanthene-based oligothiophene-layered polymers containing bithiophenes, terthiophenes, quaterthiophenes and quinquethiophenes by the Suzuki-Miyaura coupling reaction. The polymers were characterized by various spectroscopic and electrochem. methods. They were well soluble in common organic solvents and thermally stable. Effective π-π interactions among the layered oligothiophene units in the polymer backbone were not observed in the ground state as well as in the excited state. A possible application of the polymers in opto-electronic devices such as hole transporting materials is expected.

Seguin, Jean-Christophe published the artcileChemical Composition of the Unexplored Volatile Fraction of Betula glandulosa, a Prevalent Shrub in Nunavik, Quebec, Formula: C10H18O, the publication is Chemistry & Biodiversity (2022), 19(2), e202100871, database is CAplus and MEDLINE.

The volatile fraction of the leaves of Betula glandulosaICHX. has been investigated for its secondary metabolite composition by GC/MS and GC/FID. The rapid expansion of this shrub species in subarctic landscapes, like the ones found in Nunavik (Northern Quebec, Canada), highly impacts ecosystem dynamics. Yet, despite its abundance, few phytochem. investigations have yet been conducted on this species. In this study, we present the first phytochem. investigation of the volatile metabolites of B. glandulosa leaves. Although no essential oil was isolated, volatile compounds were extracted from the hydrosol by steam distillation The main metabolites observed were linalool (14.6-19.0 %), C6 oxylipins (known as green leaf volatiles, GLV; total of 18.2-40.2 %), eugenol (1.6-8.6 %) and α-terpineol (3.3-4.8 %). Dwarf birch is an important food source for insects and herbivores, so knowledge of its metabolite composition could help understand parts of its functional role in subarctic ecosystems. The composition of the volatile fraction could serve as marker for differentiating B. glandulosa from other dwarf birch species like Betula nana L.

Garces, Karin published the artcileIridium-Catalyzed Hydrogen Production from Hydrosilanes and Water, Formula: C6H16OSi, the publication is ChemCatChem (2014), 6(6), 1691-1697, database is CAplus.

The iridium(III) complex [Ir(H)(CF₃SO₃)(NSiN)(coe)] (NSiN=fac-coordinated bis(pyridine-2-yloxy)methylsilyl, coe=cyclooctene) has been proven to be an effective catalyst precursor for hydrogen production from the hydrolysis of hydrosilanes at room temperature The reaction performance depends both on the nature of the silane and the solvent. Interestingly, high turnover frequencies of around 10⁵ h^-1 were obtained by using Et₂SiH₂ or (Me₂HSi)₂O as hydrogen sources and THF as the solvent. Moreover a mechanistic insight into this Ir-catalyzed hydrogen generation process, based on both theor. calculations and NMR spectroscopy, is reported. The overall catalytic cycle can be viewed as a two-stage process that involves water-promoted Si-H bond activation followed by water splitting by a proton transfer.
