A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

open access: yesAdvanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

p-Nitrophenol degradation by activated persulfate

open access: yesEnvironmental Technology & Innovation, 2021
Abstract The degradation of p-nitrophenol (PNP), which is listed as a priority pollutant by the Environmental Protection Agency (EPA), was investigated in this work by the activated persulfate oxidation. Different forms of persulfate activation (namely thermal, by medium basification and with an iron salt catalyst) were evaluated, apart from founding

Dual‐Substrate Synergistic Photocatalysis: Exogenous Reagent‐Free Co‐Removal of Phenol and Cr(VI) via Electron‐Donor‐Mediated Redox Coupling over Modified Carbon Nitride

open access: yesAdvanced Science, EarlyView.
An exogenous reagent‐free dual‐substrate strategy harnesses phenol as an intrinsic electron donor to drive synchronous phenol degradation and Cr(VI) reduction over modified carbon nitride. π–π stacking and hydrogen bonding direct electron transfer to the catalyst, enriching photogenerated electrons and accelerating Cr(VI) reduction 6.4‐fold. This waste‐

Quantitative evaluation of the alkaline phosphatase activity in industrial and traditional dairy products supplied in Ahvaz as an indicator of pasteurization [PDF]

open access: yesBihdāsht-i Mavādd-i Ghaz̠āyī, 2017
Alkaline phosphatase is an indigenous milk enzyme and is probably, the most important indigenous milk enzyme from a dairy technology viewpoint which is used to determine the efficacy of the pasteurization process.

Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression

open access: yesAdvanced Science, EarlyView.
The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.

A NOTE ON THE ETHYLATION P-NITROPHENOL

open access: yes, 1945
p-Nitrophenetole constitutes the starting material for the manufacture of phenacetin, an important synthetic drug. Nitrophenetole is generally prepared by heating the sodium salt of p-nitrophenol with ethyl chloride in an autoclave or with ethyl bromide at ordinary pressure.

Phosphate status and acid phosphatase activity in soil and ectomycorrhizas in two mature stands of scots pine (Pinus sylvestris L.) exposed to different levels of anthropogenic pollution

open access: yesActa Societatis Botanicorum Poloniae, 2014
The relations between anthropogenic environmental pollution and the level of inorganic phosphorus in soil, enzyme activities of extracellular soil acid phosphatase and the surface acid phosphatase of excised ectomycorrhizas of Scots pine (Pinus ...

Magnetic cotton textile wastes pyrolyzed by ferric cerium oxide for degradation of p-nitrophenol by catalytic ozonation

open access: yesWater Science and Technology, 2021
In this paper, magnetic cotton textile wastes pyrolyzed by ferric cerium oxide (FexCey oxide/PC) were synthesized for degradation of p-nitrophenol by catalytic ozonation, and the optimal Fe-Ce ratio was 10:1.

One‐Step Preparation of Lanthanide‐Doped Polyurea Multicolor Microspheres for Versatile Fluorescent Applications

open access: yesAdvanced Science, EarlyView.
Lanthanide‐doped polyurea microspheres are prepared via a facile one‐step precipitation polymerization. They exhibit strong hydrogen‐bonding and coordination interactions with excellent properties, including multicolor emission, high quantum yield (75.3%), remarkable stability, redispersibility, and biocompatibility.

Chiral Plasmonic Printing of Discrete Hierarchical Chiral Au@Chiral Ag Semi‐Core‐Shell Nanorods With Chiral Plasmon‐Enhanced Photocatalysis

open access: yesAdvanced Science, EarlyView.
Chiral plasmonic printing uses CPL as a chiral stimulus to guide asymmetric Ag deposition on chiral Au NRs seeds. Under CPL, hot carriers reduce Ag+, and the process is controlled by both the CPL handedness and the chiral SPR. L‐dc Au generates more hot electrons under LCP than RCP, while D‐dc Au shows the opposite, revealing chiral photon‐selective ...
