Fibrous Pb(II)‐Based Coordination Polymer Operable as a Photocatalyst and Electrocatalyst for High‐Rate, Selective CO2‐to‐Formate Conversion

open access: yesAdvanced Functional Materials, EarlyView.
A coordination polymer [Pb(tadt)]n prepared by a microwave‐assisted solvothermal method selectively reduces CO2 into formate under visible light with a high apparent quantum yield of ≈25% at 400 nm. It can function as a pre‐catalyst, along with conductive Ketjen Black, to form an active PbCO3/Pb3(CO3)2(OH)2 mixture that exhibits a high Faradaic ...

HoloInjection: augmented reality support for CT-guided spinal needle injections

open access: yesHealthcare Technology Letters, 2019
The correct placement of needles is decisive for the success of many minimally-invasive interventions and therapies. These needle insertions are usually only guided by radiological imaging and can benefit from additional navigation support.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

A Tale of Two Needles

open access: yes, 2013
Looking back, I guess the name should have been my first clue. “Alternative” medicine? “Complementary” medicine? What is it about these medical practices, which to me are completely traditional, that places them in a secondary position to other medicinal

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

open access: yesAdvanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Patients’ Knowledge of and Practices Relating to the Disposal of Used Insulin Needles [PDF]

open access: yes, 2010
Objective: To determine (1) how patients currently dispose of used insulin needles, (2) whether patients were educated about disposal of their used insulin needles, and (3) who educated patients about the disposal of their used insulin needles.Methods: A

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

open access: yesAdvanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.
