Beyond wound sealing: A dual‐functional adhesive nanofiber membrane promoting coagulation and osteogenesis in extraction sites

open access: yesBMEMat, EarlyView.
Inspired by the suction mechanics of octopus suckers, a dual‐layer nanofiber membrane integrates antibacterial protection, strong wet adhesion, and osteogenic support, offering a bioinspired strategy for effective hemostasis and alveolar bone preservation.

Analysis of Tooth Profile Characteristics and Meshing Characteristics of Double Cycloid Needle Tooth Transmission

open access: yesJixie chuandong, 2023
In order to solve the problems of the traditional output structure of the cycloid pinion transmission, such as easy damage and complex structure, a new type of cycloid pinion gear is proposed by applying the internal and external cycloid tooth profile to the field of NN-type less differential planetary gear transmission, and the analysis of its tooth ...

Laughing all the way to the bank? Alternative comedy in the provinces

open access: yes, 1994
Metropolitan snobbery and the logistics of scale both militate against the success of comedians working in the regions. Yet, as Oliver Double here argues, the scene has been a lively one, often daring in its style and range alike – at least until the ...

An experimental method to measure gear tooth stiffness throughout and beyond the path of contact [PDF]

open access: yes, 2001
A method is presented that allows the accurate measurement of the tooth pair stiffness of a pair of spur gears. The method reveals the stiffness behaviour throughout the full length of the normal path of contact and also into the extended contact region ...

A biomechanical optimized Zr58Cu25Al14Nb3 bulk metallic glass dental implant improves peri‐implant stress distribution and bone quality under physiological loading

open access: yesBMEMat, EarlyView.
This study reports a novel Zr58Cu25Al14Nb3 bulk metallic glass that possesses high mechanical strength and low elastic modulus, which further promotes efficient mechanotransduction and significantly improves peri‐implant bone quality upon cyclic occlusal loading.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

open access: yesBMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Developmental Morphometry of the Paranasal Sinuses in Subjects Aged 1–25 Years: A Computed Tomography Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The present study aimed to evaluate the developmental morphometry of the paranasal sinuses using computed tomography (CT) in subjects aged 1–25 years and to characterize age‐related changes in sinus dimensions, volume, and surface area throughout childhood, adolescence, and young adulthood.
