Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

open access: yesAdvanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

Kuat Rekat Tarik dan Geser Bahan Bonding pada Perekatan Awal Braket dengan Pengetsaan dan Perekatan Ulang Tanpa Pengetsaan

open access: yesJournal of Dentistry Indonesia, 2015
The incidence of loose brackets during orthodontic treatment has reached 5%; therefore, loose brackts should be rebonded. Rebonding without etching might decrease chair time without compromising bond strength.

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

The Latest Advance in Bracket Technology: Self-Ligating Brackets [PDF]

open access: yes, 2007
During the last 10 years, a wide range of metal, plastic, and ceramic brackets, based on the straight-wire system, have become available. The latest advance in bracket improvement is the development of self-ligating brackets in orthodontics.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.
