Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

The expectations of fathers concerning care provided by midwives to the mothers during labour

open access: yesHealth SA Gesondheid: Journal of Interdisciplinary Health Sciences, 2012
Midwives have been criticised for neglecting the expectations and needs of fathers. They either ignore the fathers or pressure them into becoming more involved than they would choose, if allowed to provide support to the mothers during labour.

Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

open access: yesAdvanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

Contribution of Emotional, and Physical Support of Fathers in Exclusive Breastfeeding

open access: yesAl-Sihah: The Public Health Science Journal
Exclusive breastfeeding coverage in Bogor Regency remains low, affecting infant growth and development during the first six months of life. Paternal support, as a key determinant, has been insufficiently explored. This study assessed the types of support

Potential versus Reality: The Importance of Resources in Challenging Gendered Family Practices

open access: yesSociologica, 2018
Family life is recognised as a central domain for the achievement of greater gender equality. Transformations in fatherhood policies have been key in signalling the value of both mothers and fathers as parents and reflecting new discourses about the ...

Highly Selective Adsorption of Fluorinated Gases by Porous Organic Cages – Effects of Fluorinated Side‐Chains

open access: yesAdvanced Materials, EarlyView.
A systematic study of a series of porous organic cages with perfluorinated alkyl side‐chains of different lengths is presented. The structure‐property relationship of the various cages on gas sorption of highly potent greenhouse gases, such as perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) is investigated.
