Thermal Characteristics of InGaN/GaN Flip-Chip Light Emitting Diodes with Diamond-Like Carbon Heat-Spreading Layers

open access: yesInternational Journal of Photoenergy, 2014
The temperature-dependent optical, electrical, and thermal properties of flip-chip light emitting diodes (FCLEDs) with diamond-like carbon (DLC) heat-spreading layers were investigated.

Consideration on Surface Modification of Steel Dies to Reducing the Plastic Sticking in the Forming Process

open access: yesTribology Online, 2012
Plastic parts such as syringe, phone cases, containers, etc. are formed in the mold under the molten temperature and with the high pressure. Plastic sticking to the mold surface during forming process is a serious practical problem for the manufacturing.

A Supramolecular Thermal Switch for Precision Pyroptosis via Host−Guest Recognition and Electrostatic Interactions

open access: yesAdvanced Science, EarlyView.
A supramolecular pyroptotic thermal switch encapsulates I3− within β‐cyclodextrin (β‐CD) and undergoes CaCO3 mineralization. Upon lysosomal acidification, CaCO3 is degraded, releasing Ca2+ and I3−. Concurrently, BODIPY activation converts I3− into I2, inducing oxidative stress and Ca2+ overload, which together trigger caspase‐3/GSDME‐mediated ...

Oil Free Machinery and “Zero Wear”- Dream or Reality?

open access: yesTribology Online, 2011
Original equipment manufacturers (OEMs) and end-users perceive “Zero Wear” differently. The “Zero Wear” approach will be put into a general relation for different applications and illuminated by individual paths, either based on ...

Iron, nitrogen and silicon doped diamond like carbon (DLC) thin films: A comparative study

open access: yes, 2017
The X-ray absorption near edge structure (XANES), X-ray photoelectron spectroscopy (XPS), valence band photoemission (VB-PES) and Raman spectroscopy results show that the incorporation of nitrogen in pulsed laser deposited diamond like carbon (DLC) thin ...

Lithium Niobate Electro‐Optic Photonic Processor for Variational Quantum Eigensolver

open access: yesAdvanced Science, EarlyView.
An integrated lithium‐niobate‐on‐insulator ququart processor implements an electro‐optically controlled photonic variational quantum eigensolver using single photons encoded in four path modes. Bell‐basis‐emulating ququart projective measurements reduce measurement settings while achieving chemical‐accuracy‐level molecular‐energy estimation.

Engineered Xenogeneic Bone Scaffold with IL‐10 Nanodelivery System: Immunomodulation and BMSC Fate Programming for Skull Defect Repair

open access: yesAdvanced Science, EarlyView.
A multifunctional regenerative composite is constructed by 3D‐printing thermosensitive PNIPAM hydrogel embedded with MPDA@IL‐10 nanoparticles and autologous BMSCs onto antigen‐depleted porcine bone matrix for beagle critical‐sized skull defect reconstruction.

Wear modelling of diamond-like carbon coatings against steel in deionised water

open access: yes, 2014
Diamond-Like Carbon (DLC) coatings are thin protective surface coatings used to reduce friction and minimise wear in a wide range of applications. The focus of this work is the use of DLC coatings within Rolls-Royce’s pressurised water reactors. A strong

Formation of periodical nanostructure formed on diamond-like carbon film (Consideration of the formation of mechanism)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Recently it was reported that a periodic nanostructure was formed by femtosecond pulse laser (λ = 800 nm, fr = 1 kHz) irradiation at the fluence slightly above the ablation threshold over the surface of diamond-like carbon (DLC) films.

Synthesis, structure and properties of nanolayered DLC/DLC films [PDF]

open access: yes, 2003
Diamondlike carbon (DLC) films have been explored extensively in the past due to their highly attractive properties. However, the high level of internal stress developed during growth prevents deposition of thick films.
