Sustainable Synthesis of P‐Doped Carbon Nitride From Fertilizer Sources for Enhanced Photocatalysis

ChemPhotoChem, Volume 10, Issue 5, May 2026.
A new P‐doped carbon nitride was synthesized from the combination of thiourea and (NH4)2HPO4 by a straightforward and mild approach. The final material shows a fourfold higher specific surface area and excellent suppression of charge carrier recombination.

Drift measurements for conditions of hydrogen cyanamide spraying in kiwifruit

New Zealand Plant Protection, 2018
Kiwifruit are sprayed in late winter with hydrogen cyanamide to enhance with bud burst. The trellis layout of kiwifruit vines in combination with the canopy dormancy at that time of year means that a higher portion of the spray is able to drift away from the canopy.

Dormancy Patterns of Apple Trees Grown in a Mild Winter Region: A Breakpoint Model Analysis

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Climate change poses a significant challenge to the production of temperate climate fruit trees, since the dormancy of these species is regulated by the chill and heat accumulation during winter and early spring. This study aimed to identify the dormancy evolution patterns of three apple cultivars (“Galaxy,” “Fuji Suprema,” and “Eva”) in a ...

Chill unit accumulation and necessity of rest breaking agents in South African table grape production regions

BIO Web of Conferences, 2014
Cultivation of table grapes in warm regions of South Africa is complicated by problems associated with delayed and uneven bud break. Rest breaking agents, mainly hydrogen cyanamide, are applied to overcome these problems.

Prebiotic Organic Chemistry of Diketopiperazines

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

Biosynthetically‐Inspired Oxidative Cleavage Platform Enables Rapid Access to Diverse and Architecturally Complex Chemotypes From Indole Alkaloids

ChemistryEurope, Volume 4, Issue 4, April 2026.
We report a biosynthesis‐inspired ring distortion approach that involves oxidative ring cleavage, ring rearrangement, and ring expansion reactions from a diverse collection of indole alkaloids and derivatives. This chemical synthesis approach led to the synthesis of >25 distinct chemotypes from 14 indole alkaloids.
