Photonic chip based optical frequency comb using soliton induced Cherenkov radiation

open access: yes, 2015
By continuous wave pumping of a dispersion engineered, planar silicon nitride microresonator, continuously circulating, sub-30fs short temporal dissipative solitons are generated, that correspond to pulses of 6 optical cycles and constitute a coherent ...

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

open access: yesAdvanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Thulium distributed-feedback fiber lasers [PDF]

open access: yes, 2006
Rare-earth doped silica bers have already shown their huge potential in the telecom and sensing industry. The most successful of all rare-earths today is erbium, well known for its ideal characteristics for optical amplication in the telecommunications frequency window. Yet, interest is growing in the utilization of other rare-earth doped bers to reach

Injectable Porous Microspheres Loaded With Biomimetic Preconditioned Bone Marrow Mesenchymal Stem Cell‐Derived Exosomes for Vascularized Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Schematic illustration of injectable PDA‐modified GelMA microspheres loaded with BioPre‐Exos for vascularized bone regeneration. ABSTRACT Critical‐sized bone defects remain a highly challenging clinical problem due to insufficient intrinsic self‐healing capacity.

Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs

open access: yesAdvanced NanoBiomed Research, EarlyView.
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.

Linewidth-Narrowed, Linear-Polarized Single-Frequency Thulium-Doped Fiber Laser Based on Stimulated Brillouin Scattering Effect

open access: yesIEEE Photonics Journal, 2017
A 2-μm linear-polarized hybrid Brillouin–Thulium fiber laser (BTFL) was experimentally investigated for linewidth narrowing. The low threshold for the BTFL in terms of Brillouin pump of ∼200 mW, benefits from the gain of ...

Tensile Stimulation in Biorelevant Culture Conditions Enhances MSC and TPSC Tenogenesis on Aligned Electrospun Scaffolds

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biomimetic electrospun scaffold incorporating GDF‐7‐loaded mesoporous silica nanoparticles, combined with mechanical stimulation and physiological oxygen tension, guides tenogenic differentiation of mesenchymal stromal cell and tendon progenitor stem cell. This integrated approach enhances cell proliferation, matrix deposition, and tendon‐specific gene
