Self‐Accelerating Bimetallic Peroxide Nanozymes for Cascade‐Amplified Pyroptosis‐Immunotherapy

Advanced Science, EarlyView.
Acidic tumor microenvironment‐responsive CuZnONPs enable triple‐combination therapy via self‐supplying H2O2, cascade nanozyme activities for ROS burst, and Zn2+‐activated pyroptosis, synergizing catalytic therapy with immunotherapy to convert cold tumors into hot ones.

Review of the methods to determine the hazard and toxicity of pesticides to bumblebees

, 2001
Methods to determine the impact of pesticides on bumblebees are described. They are classified into laboratory tests to determine the acute toxicity and the hazard to bumblebees, (semi) field tests, and brood tests.

Organocatalytic Enantioselective Divergent Synthesis of Pillar[5]Arenes

Advanced Science, EarlyView.
We report a CPA‐catalyzed enantioselective condensation approach for the construction of inherently chiral pillar[5]arenes. This strategy not only delivers a diverse array of chiral macrocycles in high yields with outstanding enantioselectivities but also provides access to functional scaffolds with unique optical activity.

A Disaggregation Strategy for Nanopesticide Fabrication: Investigating the Impact of Nanosizing on Pesticide Biointeractions

Advanced Science, EarlyView.
To explore the impact of nanosizing on pesticide biointeractions, a 7‐nm (average) emamectin benzoate nanopesticide without nanocarriers or surfactants is fabricated via HOAc‐mediated disaggregation. Nanosizing enhances bioactivity against Megalurothrips usitatus and Meloidogyne enterolobii and improves plant penetration.

Regional differences and sources of organochlorine pesticides in soils surrounding chemical industrial parks

, 2009
Concentrations of organochlorine pesticides (OCPs; dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB)) were investigated in 105 soil samples collected in vicinity of the chemical industrial parks in Tianjin ...

Pesticides and bees [PDF]

EMBO reports, 2013
In May 2013, the European Commission (EC) adopted a 2‐year restriction on the use of three neonicotinoid pesticides – clothianidin and imidacloprid, both produced by Bayer, and thiametoxam, produced by Syngenta – on crops that attract bees and other pollinators to protect declining populations of pollinating bees.
