Noble metal elements are ubiquitous in our everyday life, from medical applications to electronic devices and synthetic chemistry. Iridium is one of the least abundant elements, and despite its scarcity, it remains essential for efficient and active catalytic processes. Consequently, the development of heterogeneous catalysts with the presence of active iridium sites is of enormous interest as it leads to the improvement of their recyclability and reusability. Here, we demonstrate a strategy to incorporate iridium atoms into metal-organic frameworks (MOFs), as part of their secondary building units (SBUs), resulting in robust and reusable materials with heterogeneous photocatalytic activity.

Background: Assistive technology (AT) plays a crucial role in empowering people living with dementia (PLWD) to perform tasks independently, enhancing their autonomy and dignity. To build on this foundation, our proposal introduces a home-based reminder system designed to further support PLWD in their daily lives.
Hypothesis: Memory aid technology, in particular reminder systems, can be developed to prospectively provide PLWD with autonomy and independence, to alleviate responsibilities and time commitments of caregivers and clinicians, and to enable remote behavioral monitoring.

Twisting 2D van der Waals magnets allows the formation and control of different spin-textures, as skyrmions or magnetic domains. Beyond the rotation angle, different spin reversal processes can be engineered by increasing the number of magnetic layers forming the twisted van der Waals heterostructure. Here, pristine monolayers and bilayers of the A-type antiferromagnet CrSBr are considered as building blocks.

Background: Research has demonstrated that staff working in Paediatric Critical Care (PCC) experience high levels of burnout, post-traumatic stress and moral distress. There is very little evidence of how this problem could be addressed.
Aim: To develop evidence-based, psychologically informed interventions designed to improve PCC staff well-being that can be feasibility tested on a large scale.

Expanded heterohelicene composing of alternating linearly and angularly fused multi-resonance (MR) skeleton has garnered wide interest for their promising narrowband emission. Herein, a pair of sym- and asym-expanded heterohelicene isomers are firstly developed by merging boron/oxygen (B/O)-embedded MR triangulene and indolo[3,2,1-jk]carbazole units via one-shot synthesis. Owing to the fully resonating extended helical skeleton, the target heterohelicenes exhibit significantly narrowed spectra bandwidth while emission red-shifting, thus affording deep-blue narrowband emission with peak at around 460 nm, full-width-at-half-maximum (FWHM) of merely 18 nm and near-unity photoluminescence quantum yields.

Osteoporosis has been usually considered a female disease, generally causing more fracture risk and complications in adult and older women compared to older men. While vertebral fractures occur in a small proportion of men during middle age, men generally fracture about 10 years later than women, with significant increases in fracture risk after about age 75. Independent of age, men experiencing fragility fractures have a higher risk of life-threatening events compared to women, but the risk of secondary fragility fracture overlaps between men and women.
