Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

open access: yesChemCatChem, Volume 17, Issue 15, August 7, 2025.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Bacillus as Siderophore and Iron-bioremoval Bacteria [PDF]

open access: yes, 2015
ome Bacillus strains can produce siderophore. Siderophore is a chelating agent for ferric iron as a response to low iron environment. Bacillus has ability as iron bioremoval.

Chemical constitutions in the Colour Index™: A century of colourant classification

open access: yesColoration Technology, Volume 141, Issue 4, Page 427-472, August 2025.
Abstract This article details how the Colour Index™ (CI) system categorises and unambiguously labels commercial dyes and pigments based upon their chemical constitutions. It outlines the current process by which colourants that are new to the market find a place within CI and acquire generic identifiers.

Functional Dendrimer Nanogels for DNA Delivery and Gene Therapy of Tumors

open access: yesAngewandte Chemie, Volume 137, Issue 30, July 21, 2025.
Dendrimer nanogels are designed by emulsion‐free method, endowing them with dual‐active groups, o‐hydroxyl amine, temperature‐responsiveness, polyampholyte property, and self‐triggered aminolysis. With these unique characters, dendrimer nanogels display high gene transfection and therapeutic efficacies with low side effects, thus solving the dilemma ...

Wildfire‐Induced Losses of Soil Particulate and Mineral‐Associated Organic Carbon Persist for Over 4 Years in a Chaparral Ecosystem

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
Wildfires can lower soil carbon (C) stocks directly through combustion, but also indirectly during post‐fire recovery if microbial respiration outpaces photosynthetic C inputs. To assess controls over post‐fire soil C stocks, we measured particulate organic carbon (POC), mineral‐associated organic carbon (MAOC), and microbial and plant communities for ...

Transcriptomic and Proteomic Response to Grain Filling Reveal Potential Grain Size Regulation Mechanisms in Quinoa (Chenopodium quinoa Willd)

open access: yesPlant Breeding, Volume 144, Issue 4, Page 580-594, August 2025.
ABSTRACT Grain size is an important factor affecting quinoa yield, and studying the molecular mechanism of quinoa grain size formation is of great significance for cultivar selection. In this study, we analysed phenotypic traits, conducted RNA sequencing and proteomic detection during grain filling in different developmental stages.
