Effect of phenolic compounds on nematodes- A review [PDF]

, 2010
The term, phenolics has been used to describe a group of structurally diverse plant secondary metabolites. This group includes metabolites derived from the condensation of acetate units (terpenoids), those produced by the modification of aromatic amino ...

Chemical Methods for Peptide and Protein Backbone Cleavage

ChemistryEurope, EarlyView.
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

Defect Suppression via Tailoring Functionalized Additives for Efficient and Stable CsPbI3 Perovskite Solar Cells

Carbon Energy, EarlyView.
This study proposed a structure‐designed benzohydrazide derivative, namely 4‐methoxybenzohydrazide (MeOBH), as an additive to regulate crystallization, passivate defects, optimize energy‐level structure, and enhance phase stability of β‐CsPbI3 perovskite films.

Hydrazinolysis of lipids and analysis of their constituent fatty acids

Journal of Lipid Research, 1983
Treatment of O-acyl lipids with hydrazine degrades them to hydrazides of the constituent fatty acids. These hydrazides react with acetone to yield less polar and more volatile N'-isopropylidenealkanohydrazides, R-CO-NH-N = C(CH3)2, which strongly absorb ...

Identification of Natural Isonitriles Through Ligation to an Azomethine Imine Probe

Chemistry – A European Journal, EarlyView.
The azomethine imine (AMI)–isonitrile (NC) ligation allowed for the chemoselective detection of natural isonitriles in bacteria and fungi. The reactivity‐based screening establishes a new stereogenic center, thereby allowing for facile distinction between chiral and achiral isonitriles. The work also unraveled a unique reactivity of isonitriles bearing

Recent Advances on Self‐Powered Metal Halide Perovskite Photodetectors

EcoEnergy, EarlyView.
This review outlines that metal halide perovskites, with high absorption coefficient and carrier mobility, enable self‐powered photodetectors. These devices operate without external power, with improvements via structural optimization, film engineering, and defect passivation, showing promise in smart sensors and Internet of Things applications ...

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
