3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

open access: yesAdvanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...

The Allocation of Development Aid Assistance: Do new donors have old motives? [PDF]

open access: yes
The aid allocation literature explores the motives behind development aid assistance. This literature is enormous, yet surprisingly, the extant empirical studies have in the main only focused on the motives of established donors. Consequently, relatively

Autologous Blood Donation

open access: yesAnesthesiology Clinics of North America, 2005
Preoperative autologous blood donation has become accepted as a standard practice in elective surgery. Subsequent improvements in blood safety and evolving surgical techniques resulting in less blood loss have caused a national decline in preoperative autologous blood donation by approximately 50%.

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Disparities in being able to donate human milk impacts upon maternal wellbeing: Lessons for scaling up milk bank service provision

open access: yesMaternal and Child Nutrition
Receiving donor human milk for a baby can have a protective effect upon parental wellbeing. A growing body of research also finds that being able to donate milk to a milk bank, particularly after infant loss, can also boost maternal wellbeing through ...

Dimensions of individual religiosity and charity:Cross national effect differences in European countries? [PDF]

open access: yes, 2006
The relation between religiosity and donations to charity has frequently been subject of research. We analyzed effects of dimensions of individual religiosity (Glock and Stark 1966) on people's intention to donate to the poorest countries.

Diels‐Alder Click Chemistry as a Dynamic‐Covalent Crosslinking Method in Spheroid‐Encapsulating Hydrogels for Cartilage Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This research shows the development of hydrogels with Diels‐Alder click chemistry for engineering cartilage‐like tissue. The hydrogels support cartilage spheroids which could be cultured for at least 28 days. Furthermore, the spheroids showed a tendency to fuse together into a more consistent construct, and produced important components needed for ...

When donors feel generous: economic research on prosocial behavior [PDF]

open access: yes
New research shows that people donate time and money at the level of peers to groups with which they identify—and that they want to see the impact of their giving.
