Green Light Vat‐Photopolymerisation for 3D Printing Hydrogels with Complex Lattice Structures

open access: yesAdvanced Materials Technologies, EarlyView.
Green‐light vat‐photopolymerization (gDLP) at 514 nm enables high‐resolution 3D printing of water‐rich hydrogels (60% water) with 50 μm$\umu{\rm m}$ layer precision. This study pioneers a cost‐effective, modified desktop printer and novel bioresins to fabricate complex vascularized lattices.

Matter of Trust

open access: yesAdvances in Social Work, 2020
Mental health problems among children and adolescents are widespread. Parents seeking information about child mental health problems and treatments face numerous barriers, including fear of stigmatization and uncertainty about where to seek help. In this

Normative Empire Europe: The European Union, its Borderlands, and the ‘Arab Spring’

open access: yes, 2016
Focusing on the EU's relations with its periphery, this paper takes issue both with persistent ‘normative’ conceptions of the EU's international role in the European Studies literature and with the constructivist–rationalist divide in IR theory.

Fabrication Optimization of van der Waals Metasurfaces: Inverse Patterning Boosts Resonance Quality Factor

open access: yesAdvanced Optical Materials, EarlyView.
An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.

On Empirical Generalisations [PDF]

open access: yes, 2012
Manipulationism holds that information about the results of interventions is of utmost importance for scientific practices such as causal assessment or explanation. Specifically, manipulation provides information about the stability, or invariance, of the (causal) relationship between (variables) X and Y: were we to wiggle the cause X, the effect Y ...

Empirical Negation [PDF]

open access: yesActa Analytica, 2012
An extension of intuitionism to empirical discourse, a project most seriously taken up by Dummett and Tennant, requires an empirical negation whose strength lies somewhere between classical negation (‘It is unwarranted that. . . ’) and intuitionistic negation (‘It is refutable that. . . ’).

Adducin‐1 Facilitates Influenza Virus Endosomal Trafficking and Uncoating by Regulating Branched Actin Dynamics and Myosin IIB Activity

open access: yesAdvanced Science, EarlyView.
In this study, a novel mechanism is unveiled by which ADD1, acting as a molecular switch, coordinates actin branch dynamics and the transport of endocytic viruses and cargoes. Phosphorylation of ADD1 at Ser726 reduces actin branch density, enhancing endosome fusion and attachment to microtubules.

Student perspectives on the use of universal design for learning in virtual formats in higher education

open access: yesSmart Learning Environments, 2022
Universal design for learning (UDL) in higher education may be a useful tool in supporting the heterogenous higher education student population, specifically in supporting student academic outcomes and retention.

Multifunctional Infrared Polarizer Based on Aligned Growth of High‐Density Boron Nitride Nanotubes

open access: yesAdvanced Science, EarlyView.
This paper presents a novel method for the high‐density, aligned growth synthesis and purification of boron nitride nanotubes (BNNTs). The polarization sensitivity and linear dichroism characteristics of BNNTs in the near‐infrared and mid‐infrared bands are comprehensively verified.
