Tunable and Recyclable Piezoelectric Biomaterials via Ion‐Directed Guanine‐Quadruplex Assembly

open access: yesAdvanced Functional Materials, EarlyView.
Guanine‐quadruplex (GQ) assemblies, formed via ion‐mediated self‐assembly of amphiphilic guanine derivatives, are introduced as tunable and recyclable piezoelectric biomaterials. Distinct alkali ions induce unique dipole configurations and piezoelectric outputs, with K⁺ yielding the highest performance.

Use of Partial Purified Lipase From local Chicken kidney for Improvement the Flavor of Butter Fat

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
    Lipase was extracted by Sodium acetate buffer (pH=6; 0.05M) Containing 0.1M NaCl. Enzyme content of crude extract was concentrated by gradual addition of ammonium sulfate at 30-60% saturation.

Full‐Spectrum Solar Harvesting and Desalination Enabled by Supra‐Nano Amorphous Ruthenium Dioxide – Mineral Composites

open access: yesAdvanced Functional Materials, EarlyView.
A mineral‐based supra‐nano amorphous ruthenium dioxide composite (a‐Ru0.5‐AM) was designed, achieving 97% broadband solar absorption. Under one sun, it reaches 87.91 ± 0.32 °C with a distinct thermal buffering effect that favors thermal confinement.

The refolding of recombinant human liver methylmalonyl-CoA mutase from inclusion bodies produced in Escherichia coli : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]

open access: yes, 1998
Human methylmalonyl-CoA mutase (hMCM) is an adenosylcobalamin-dependent enzyme that catalyses the structural rearrangement of (R)-methylmalonyl-CoA to succinyl-CoA as pan of the catabolism of the branched chain amino acids valine, leucine and isoleucine,

Programmable DNA‐Peptide Hybrid Nanostructures for Potent Neutralization of Multiple Influenza a Virus Subtypes

open access: yesAdvanced Functional Materials, EarlyView.
A multivalent antiviral platform based on honeycomb‐shaped DNA nanostructures (HC–Urumin) is developed to enhance the potency and breadth of the host defense peptide Urumin. Through spatially patterned trimeric presentation, HC–Urumin disrupts influenza A virus entry, improves cell viability, and reduces disease severity in vivo‐offering a modular and ...

Design of Efficient and Mechanically Robust Anion Exchange Membrane for Water Electrolysis Achieved by Chemically Crosslinked Elastomers using Polyfluorene‐Based Conjugated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
High‐performance SEBS‐PFB AEM is developed by crosslinking SEBS‐amine with polyfluorene‐based crosslinker containing benzene spacer. With the superior electrochemical and mechanical properties, SEBS‐PFB enabled an AEMWE single cell to achieve a high current density of 14.0 A cm−2 at 2.0 V and 80 °C in 1 m KOH, using a PtRu/C cathode and Ni2Fe anode ...

High‐Entropy Perovskite Nanofibers for Bifunctional Air Electrodes in Reversible Protonic Ceramic Electrochemical Cells

open access: yesAdvanced Functional Materials, EarlyView.
High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.
