PET-RAFT
Photoinduced Electron/Energy Transfer Reversible Addition-Fragmentation Chain-Transfer (PET-RAFT) polymerization, proposed for the first time in 2014, is based on an alternative activation of the thiocarbonylthio compounds through photoredox catalysts (PCs). This last presents significant advantages compared to other photochemical techniques in terms of applicability, cost, and sustainability.

Pesticides Removal Using Metal Oxide and Their Composites
Persistent organic chemicals (POPs) are highly hazardous to the ecosystem and living organisms. Their non-biodegradability allows them to accumulate easily in the food chain, affecting both humans and wildlife. Pesticides are one class of POPs with half-lives that can extend to years. They have been used abundantly to control the growth of the crops by exterminating pests including insects, fungi, and microorganisms in agricultural farms.

Pesticide residues detection by Characteristics
The excessive use or abuse of pesticides leads to residues in food, which can threaten human health. Therefore, there is an extremely urgent need for multi-analyte analysis techniques for the detection of pesticide residues, which can be applied as screening techniques for food safety monitoring and detection. Recent developments related to rapid multi-residue detection methods for pesticide residues are reviewed herein. Methods based on the inherent characteristics of pesticides are described in detail. Enzymatic inhibition-based sensors, near-infrared spectroscopy, and SERS spectroscopy based on the inherent characteristics are discussed.

Perylene Diimide-Based Optical Chemosensors for pH Probing
The precise control and monitoring of pH values remain critical for many chemical, physiological and biological processes. Perylene diimide (PDI)-based molecules and materials exhibit excellent thermal, chemical and photochemical stability, unique UV-vis absorption and fluorescent emission properties, low cytotoxicity, as well as intrinsic electron-withdrawing (n-type semiconductor) nature and impressive molecular assembly capability. These features combined enable promising applications of PDIs in chemosensors via optical signal modulations (e.g., fluorescent or colorimetric). One of the typical applications lies in the probing of pH under various conditions, which in turn helps monitor the extracellular (environmental) and intracellular pH change and pH-relying molecular recognition of inorganic or organic ions, as well as biological species, and so on.

Perspective for High-Value C2 Chemicals
The oxidative coupling of methane (OCM) to C2 hydrocarbons (C2H4 and C2H6) has aroused worldwide interest over the past decade due to the rise of vast new shale gas resources. However, obtaining higher C2 selectivity can be very challenging in a typical OCM process in the presence of easily oxidized products such as C2H4 and C2H6. Regarding this, different types of catalysts have been studied to achieve desirable C2 yields.

Peroxyacetic Acid Pretreatment in Lignocellulose Biorefinery
The stubborn and complex structure of lignocellulose hinders the valorization of each component of cellulose, hemicellulose, and lignin in the biorefinery industries. Therefore, efficient pretreatment is an essential and prerequisite step for lignocellulose biorefinery. A considerable number of studies have focused on peroxyacetic acid (PAA) pretreatment in lignocellulose fractionation and some breakthroughs have been achieved in recent decades.

Perovskites for CO2 Reduction
Due to their outstanding operational and compositional properties, perovskite-based structures have already been studied as an important class of solid-state components for electrochemical (EC), photoelectrochemical (PEC), and photovoltaic–electrochemical (PV-EC) CO2 reduction, showing great potential in their catalytic activity and device stability and with a promising window for further technological developments.

Perovskites Application in the Sensing of NPNC Biomarkers
erovskites are materials with a chemical formula of the form ABO3 (oxide-based form) or ABX3 (halogen-based form), ordered in a specific arrangement of atoms in a crystal lattice. It consists of a cubic unit cell in which an atom or ion is located at the center, surrounded by a larger octahedral cage of different atoms or ions. Non-protein nitrogenous compounds (NPNC) such as urea, uric acid, creatine, and creatinine are commonly used as biomarkers of human kidney health.
