Silicon nanoparticles vs trace elements toxicity: Modus operandi and its omics bases

Frontiers in Plant Science
Phytotoxicity of trace elements (commonly misunderstood as ‘heavy metals’) includes impairment of functional groups of enzymes, photo-assembly, redox homeostasis, and nutrient status in higher plants.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

Advanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

Activación del crecimiento de Plantulas de sietecueros (Tibouchin lepidota) por Fitohormonas

Acta Biológica Colombiana, 1996
Many tropical tree species when seedling have a slow growing period that seems to be controlled by a physiological mechanism of hormonal regulation. In "sietecueros" (Tibouchina lepidota (Bnpl.) Baill), different plant hormones like polyamines, auxines ...

Fertimetro, a Principle and Device to Measure Soil Nutrient Availability for Plants by Microbial Degradation Rates on Differently-Spiked Buried Threads [PDF]

, 2018
A novel patented method (PCT/IB2012/001157: Squartini, Concheri, Tiozzo, University of Padova) and the corresponding application devices, suitable to measure soil fertility, are presented. The availability or deficiency of specific nutrients for crops is

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

Advanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Thermal stress triggers broad Pocillopora damicornis transcriptomic remodeling, while Vibrio coralliilyticus infection induces a more targeted immuno-suppression response.

PLoS ONE, 2014
Global change and its associated temperature increase has directly or indirectly changed the distributions of hosts and pathogens, and has affected host immunity, pathogen virulence and growth rates.

The Meanings of ‘Life’:Biology and Biography in the Work of J.S. Haldane (1860-1936) [PDF]

, 2011
In the course of his somewhat unorthodox career in science, the physiologist John Scott Haldane occasionally turned to biography to portray the aims and values that he associated with such a career.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

Advanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Molecular studies of Arabidopsis and Brassica with focus on resistance to Leptosphaeria maculans [PDF]

, 2001
Blackleg caused by Leptosphaeria maculans is a widespread fungal disease on B~assica napus (oilseed rape). In contrast, Arabidopsis thaliana and B. nigra are in general highly resistant. This study presents results from genomic interaction between the A.
