Effects of pupal hypoxia duration and holding temperature on quality control parameters of sterile Queensland fruit fly

open access: yesPest Management Science, EarlyView.
Queensland fruit fly pupae tolerate hypoxia up to 2 days without compromising quality. Prolonged hypoxia, especially at 25 °C, reduces emergence and flight ability. Storage at 18 °C is recommended. Abstract BACKGROUND The sterile insect technique is used to eradicate outbreaks of Queensland fruit fly (Q‐fly) Bactrocera tryoni (Froggatt) in fruit‐fly ...

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

open access: yesSustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Soft Colloidal Robots: Magnetically Guided Liquid Crystal Torons for Targeted Micro‐Cargo Delivery

open access: yesSmall, EarlyView.
Torons, topological quasiparticles in liquid crystals, can be propelled using electric fields and precisely steered with magnetic alignment, enabling programmable motion without fluid flow. In microfluidic channels, they transport colloidal cargo and exhibit novel dynamic behavior. Their uniformity, softness, and reconfigurability make torons ideal for

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

open access: yesSmall, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...

Bottom‐Up Assembly of Amorphous Metal–Organic Frameworks From Proton Conductive Metal–Organic Polyhedra

open access: yesSmall, EarlyView.
Structural control in amorphous MOFs (aMOFs) remains challenging compared to their crystalline counterparts. We report a bottom‐up strategy using metal‐organic polyhedra as predefined building units. By crosslinking these clusters, we preserve intrinsic node functionality within aMOFs, achieving proton conductivity up to 4.8 mS cm−1 at 85°C and 90% RH,
