Li-diffusion accelerates grain growth in intercalation electrodes: a phase-field study

open access: yes, 2018
Grain boundary migration is driven by the boundary's curvature and external loads such as temperature and stress. In intercalation electrodes an additional driving force results from Li-diffusion. That is, Li-intercalation induces volume expansion of the

Remote Monitoring in Myasthenia Gravis: Exploring Symptom Variability

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Myasthenia gravis (MG) is a rare, autoimmune disorder characterized by fluctuating muscle weakness and potential life‐threatening crises. While continuous specialized care is essential, access barriers often delay timely interventions. To address this, we developed MyaLink, a telemedical platform for MG patients.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Phytochemical-based nano emulsions for stored grain protection

open access: yesJulius-Kühn-Archiv, 2018
Stored grain losses caused by pest insects contribute significantly to the global food crisis. Currently, there are two main chemical control methods against stored product insect pests: fumigation with very toxic gases and grain protection by residual ...

A study of population growth of Sitophilus oryzae L. and Sitophilus granarius L. in single and mixed culture in wheat and rice : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Science at Massey University [PDF]

open access: yes, 1983
Biological interactions between organisms which contend for the same resource, have been of interest to ecologists since the days of Darwin. Although this sort of association is evident for many animal-versus-animal and plant-versus-plant situations, one
