Six-Letter Connoisseur\u27s Ladders [PDF]

open access: yes, 2001
By the time we reach six-letter words, conditions for superior ladders are much improved: nearly one-half of six-letter words are heterograms (all letters are different), the fraction of isolanos (words which have no neighbours) decreases to less than ...

Surface Passivation of HgTe Nanocrystals Enabling EG/2 Open‐Circuit Voltage and Their Coupling to Dielectric Cavity for Narrow Detection

open access: yesAdvanced Materials, EarlyView.
This article explores how the integration of a thin shell, combined with optimized surface chemistry, enables the design of photodiodes based on short‐wave infrared HgTe nanocrystals. These photodiodes achieve an open‐circuit voltage greater than half the optical bandgap, which drastically reduces dark current. The article also explores the integration

Pinning and switching of magnetic moments in bilayer graphene

open access: yes, 2009
We examine the magnetic properties of the localized states induced by lattice vacancies in bilayer graphene with an unrestricted Hartree-Fock calculation.

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Cure of chronic viral infection and virus-induced type 1 diabetes by neutralizing antibodies [PDF]

open access: yes, 2009
The use of neutralizing antibodies is one of the most successful methods to interfere with receptor–ligand interactions in vivo. In particular blockade of soluble inflammatory mediators or their corresponding cellular receptors was proven an effective ...

Bonding of Acrylic Pressure‐Sensitive Adhesives and Silicone Elastomers via Surfactant‐Assisted Plasma Activation for Soft Robotics

open access: yesAdvanced Materials Interfaces, EarlyView.
A simple strategy is presented for bonding acrylic PSAs and silicone elastomers by curing surfactant‐doped Ecoflex on oxygen‐plasma‐treated VHB. The interface reaches a maximum strength of 1.6 N/mm (over 20 times that of the control) while retaining material compliance.

Mechanically Robust MXene‐Metal Polyphenol Network Hybrid Interfaces for Multifunctional Protection of Keratin Fibers

open access: yesAdvanced Materials Interfaces, EarlyView.
Hair keratin fibers inevitably deteriorate under UV exposure, heat, and dryness. A robust composite coating assembles delaminated Ti3C2 MXene nanosheets onto keratin surfaces through biocompatible metal‐polyphenol networks of EGCG. This hybrid layer simultaneously screens UV, dissipates heat, reinforces mechanical strength, suppresses static charge ...

Fluorescence Analysis for Multi-Site Aluminum Binding to Natural Organic Matter [PDF]

open access: yes, 1998
Natural organic matter (NOM) samples isolated from different water sources in Norway were compared using their fluorescence properties. Fluorescence surfaces were observed at pH 4.36 and deconvoluted using SIMPLISMA (Windig and Guilment 1991). There were

Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers

open access: yesAdvanced Materials Technologies, EarlyView.
We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.

Development of Apparels from Silk Waste and Pineapple Leaf Fiber

open access: yesJournal of Natural Fibers, 2018
The degummed mulberry silk waste and eri silk waste were blended with degummed and bleached pineapple leaf fibers (PALF) at fiber stage in different proportions, and spun into yarn in a jute spinning system.
