Modification of kraft wood-pulp fibre with silica for surface functionalisation

open access: yes, 2008
A new science strategy for natural fibre modification was devised in which glass surface properties would be imparted to wood-derived fibre. The enhancements known from addition of silane reagents to glass fibre–polymer composites could therefore be ...

Preparing Prospective Counselors for Classroom‐Based Career Guidance Using Video Vignettes—Mechanisms and Effects

open access: yesJournal of Employment Counseling, EarlyView.
ABSTRACT Career guidance in schools is often delivered by counselors who take on instructional roles. Video vignettes are widely used in teacher education. We developed vignettes for counselor training in classroom‐based guidance in Germany. This study examines how prospective counselors engage with these vignettes and how this relates to changes in ...

Palatal donor site wound healing following mucogingival surgery using amnion‐chorion membrane: A randomized controlled clinical trial

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Free soft tissue autografts (FSTA) harvested from a patient's palate are frequently associated with significant postoperative morbidity. Several wound dressings have been applied to the palatal donor site with the aim of reducing postoperative complications and improving wound healing.

Design and fabrication of a micromachined electrostatically suspended gyroscope

open access: yes, 2008
The current paper describes the design and fabrication of a micromachined electrostatically suspended gyroscope. Electrostatic levitation is employed to suspend the rotor, eliminating the mechanical bearing and thus friction effects between the rotor and

Unique Features of Nasal Airway and Airflow Improvement Post‐Dupilumab: A Computational Cohort Study

open access: yesThe Laryngoscope, EarlyView.
The impact of dupilumab on nasal airway patency and airflow is not uniform. It is more pronounced in the middle and superior, but not inferior meatus. These unique regional changes significantly correlate with and potentially drive the improvement in patient symptoms.

Laser‐Based In Situ Diagnostics of Temperature and Material‐Growth Dynamics in Photothermal Laser Nanoprinting of ZnO

open access: yesLaser &Photonics Reviews, EarlyView.
This work elucidates the previously unknown thermal dynamics during sub‐micrometer photothermal laser printing of zinc oxide using a non‐invasive transmission‐based in situ measurement. The elevated temperatures are shown to be highly localized around the laser focal spot, reaching average temperature increases of about 113 K per mW of laser power ...

REINFORCEMENT POTENTIAL OF BLEACHED SAWDUST KRAFT PULP IN DIFFERENT MECHANICAL PULP FURNISHES

open access: yesBioResources, 2009
Bleached unrefined and refined sawdust kraft pulps were added to bleached Norway spruce thermomechanical (TMP) and pressurised groundwood (PWG) pulps in different proportions. Handsheets were prepared and tested for physical properties.
