Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Wavelength‐Dependent Differential Amplification of Raman Scattering by Chiral Gold Nanorods for Multiplexed Encoding

open access: yesAdvanced Functional Materials, EarlyView.
The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Diagnostyka postnatalna wad układu moczowego wykrytych w okresie prenatalnym. Część 1. Wady z poszerzeniem dróg moczowych

open access: yesPediatria i Medycyna Rodzinna, 2010
Szeroka dostępność prenatalnej diagnostyki ultrasonograficznej płodu niesie ze sobą korzyści pod postacią zwiększonej wykrywalności wad wrodzonych układu moczowego. Wadę taką w rutynowym badaniu podejrzewa się mniej więcej u 1/100 płodów.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Self‐Catalyzed Chemically Coalescing Liquid Metal Emulsions

open access: yesAdvanced Science
Gallium‐based liquid metal alloys (GaLMAs) have widespread applications ranging from soft electronics, energy devices, and catalysis. GaLMAs can be transformed into liquid metal emulsions (LMEs) to modify their rheology for facile patterning, processing,

Risk factor identification and prevention of osteoporosis in the primary care setting [PDF]

open access: yes, 2006
On one of her visits, MB Borg, a 54 year old lady, showed concern about her risk of developing osteoporosis. Lately, she had been listening to a series of radio and TV programmes on this matter where particular emphasis was put on bone density scans. She

Backbone Heterojunction Photocatalysts for Efficient Sacrificial Hydrogen Production

open access: yesAdvanced Functional Materials, EarlyView.
Herein, a ‘single‐component’ organic semiconductor photocatalyst is presented in which a molecular donor is bonded to a polymer acceptor. The resultant material demonstrates exceptional photocatalytic activity for hydrogen evolution in aqueous triethylamine with an outstanding external quantum efficiency of 38% at 420 nm.
