Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

open access: yesBMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Finite element modelling and load share analysis for involute worm gears with localised tooth contact

open access: yes, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Impaired healing following implant placement surgery: A case report of a modern‐day manifestation of scurvy

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...

Finite element modelling and load share analysis for involute worm gears with localized tooth contact

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the modified tooth geometry, which ensures that the worm gear teeth are in localized contact.

Five‐year tomographic and clinical evaluation of the socket shield technique: Case report

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background The socket shield technique, one modality of partial extraction therapy, aims to preserve periodontal tissues and maintain the buccal alveolar bone volume following immediate implant placement or in prosthetic pontic sites, by the strategic maintenance of a tooth root fragment.

Reduction of gear pair transmission error with tooth profile modification

open access: yes, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Hand‐powered and programmable electrowetting‐on‐dielectric droplet actuation enabled by triboelectric nanogenerator and mechanically encoded punch‐card switch array

open access: yesDroplet, EarlyView.
A hand‐powered and mechanically programmable electrowetting‐on‐dielectric platform is demonstrated by integrating a contact‐separation triboelectric nanogenerator with a mechanically encoded punch‐card switch array. This unified mechanical–electrical architecture enables autonomous, portable, and robust droplet control for field‐deployable microfluidic
