Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

A Highly Stable Zinc‐Mimosinate Metal–Organic Framework for Controlled Agrochemical Delivery

European Journal of Inorganic Chemistry, EarlyView.
The graphical abstract illustrates the design of metal–organic frameworks (MOFs) as agrochemicals constructed from active building blocks. The highly robust GR‐MOF‐25 is assembled from the natural herbicide L‐mimosine and Zn2+ ions, combining herbicidal, micronutrient, and antibacterial properties.

The potentiality of botanicals and their products as an alternative to chemical insecticides to sandflies (Diptera: Psychodidae): A review [PDF]

Journal of Vector Borne Diseases, 2014
Use of chemical pesticides is the current method for controlling sandflies. However, resistance is being developed in sandflies against the insecticide of choice that is DDT (dichlorodiphenyl trichloroethane).

Evaluation of alternative mosquito sampling methods for malaria vectors in Lowland South - East Zambia. [PDF]

, 2013
Sampling malaria vectors and measuring their biting density is of paramount importance for entomological surveys of malaria transmission. Human landing catch (HLC) has been traditionally regarded as a gold standard method for surveying human exposure to ...

Total Synthesis of rac‐Keramamine C Enabled by Intrinsic H‐Bond‐Induced Conformational Fixation of Amides

European Journal of Organic Chemistry, EarlyView.
The total synthesis of the manzamine alkaloid keramamine C (2) in its racemic form was achieved in 5 steps, with ring‐closing metathesis as the key step. The metathesis is strongly improved by an intramolecular H‐bond‐induced conformational fixation of the amide bond, inducing close proximity of the terminal double bonds in the precursor molecule.

Proteases as Insecticidal Agents

Toxins, 2010
Proteases from a variety of sources (viruses, bacteria, fungi, plants, and insects) have toxicity towards insects. Some of these insecticidal proteases evolved as venom components, herbivore resistance factors, or microbial pathogenicity factors, while ...

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

Environmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...
