A Linearly Deformable Pneumatic Scalable Microgripper for Universal Mid‐Air Micromanipulation

open access: yesAdvanced Science, EarlyView.
This work presents a fully 3D printed soft microgripper capable of active adhesion control through a pneumatic system. Its modular design can reach a high adhesion switching ratio of 373 and free release of micro‐objects at 100 μm$\umu \rm {m}$ dimension.

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

open access: yesAdvanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Multifunctional Tailoring of Fertilizer Composites Directly Derived From Phosphate Rock

open access: yesAdvanced Science, EarlyView.
A novel phosphorus‑sulfur mixed acid with urea (PSU) activation system converts low‑grade phosphate rock (LPR) into multifunctional fertilizer composites (MFCs). MFCs feature porous structures, high nutrient‑activation efficiency, superior slow‑release, and enhanced crop growth, offering a sustainable solution for integrated nutrient management and ...

Microfluidic‐Driven Lipid Nanoparticles for Improved miRNA Delivery via Endo‐Lysosomal Trafficking Optimization

open access: yesAdvanced Science, EarlyView.
This study investigates the impact of various post‐processing methods (filtration, sonication, dialysis, and heating) on lipid nanoparticles produced using microfluidics. The nanoparticles are designed for efficient delivery of miRNA into cells. The work highlights how processing conditions influence nanoparticle stability and quality, providing ...

The influence of lime sulphur on the quality and sulphur content of organic 'Royal Gala' and 'Braeburn' apples : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Agribusiness at Massey University [PDF]

open access: yes, 2007
Black spot or apple scab is a major disease in apple (Malus domestica) production. Its control is especially difficult in organic production systems that rely on copper- and sulphur-based fungicides which are not very effective and demand a high number ...
