Effects of Wheat Straw-Derived Biochar on Soil Microbial Communities Under Phenanthrene Stress

Agriculture
The potential of biochar to mediate shifts in soil microbial communities caused by polycyclic aromatic hydrocarbon (PAH) stress in farmland, thus assisting in the bioremediation of contaminated soil, remains uncertain.

1,1‐and 1,2‐Diborylalkenes: Preparation and Synthetic Applications

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
In this review, we highlight recent advances in the synthesis and reactivity of 1,1‐diborylalkenes and 1,2‐diborylalkenes, along with various transformations leading to C‐C, C‐heteroatom, and multicomponent products. By providing a comprehensive and practical resource, this review aims to assist researchers in exploring the synthetic utility of 1,1 and

High sorption of phenanthrene in agricultural soils

, 2006
We studied the sorption and desorption of 14C-labelled phenanthrene, a polycyclic aromatic hydrocarbon, on soils, both in the laboratory using batch experiments and during 6 months of natural conditions using lysimeters.

Capacity of Aromatic Compound Degradation by Bacteria from Amazon Dark Earth

Diversity, 2014
Amazon dark earth (ADE) is known for its high organic matter content, biochar concentration and microbial diversity. The biochar amount suggests the existence of microorganisms capable of degrading aromatic hydrocarbons (AHs). In an effort to investigate

Dibenzosuberene‐Winged Polycyclic Aromatic Hydrocarbons

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
The twisted acene 8, which features two dibenzosuberene “wings”, was prepared by the addition of a crowded aryne to a similarly “winged” cyclopentadienone. Compound 8 is chiral, and it has a high barrier to thermal racemization (ΔG‡rac = 36 kcal/mol), but it undergoes fast photochemical racemization even in ambient light.

Anti-inflammatory phenanthrene derivatives from stems of Dendrobium denneanum

, 2013
Cultivated Dendrobium denneanum has been substituted for other endangered Dendrobium species in recent years, but there have been few studies regarding either its chemical constituents or pharmacological effects.

Supramolecular Assembly of DNA-Phenanthrene Conjugates into Vesicles with Light-Harvesting Properties [PDF]

, 2018
Vesicle-shaped supramolecular polymers are formed by self-assembly of a DNA duplex containing phenanthrene overhangs at both ends. In the presence of spermine, the phenanthrene overhangs act as sticky ends linking the DNA duplexes together.

DNA‐Binding Properties of Iridium(III) Complexes Encompassing Design, Function and Biophysical Assessments

ChemPhysChem, Volume 27, Issue 11, 15 June 2026.
This review describes the biophysical techniques used to investigate DNA‐binding phenomena and the progress made so far in the application of iridium(III) complexes for this purpose. Ir(III) complexes offer myriad opportunities in the design and study of DNA‐binding agents and discussed examples are contextualised with complementary studies in ...

Synthesis and Reactivity of Iodepinium Salts

European Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
An efficient oxidative cyclization of (Z)‐iodostilbenes grants access to the long‐elusive class of seven‐membered diaryliodonium salts — the iodepinium triflates. X‐ray analysis reveals their distinctly nonplanar geometry, while reactivity studies uncover unprecedented pathways, including copper‐mediated conversion to phenanthrene and chalcogen‐induced
