STM and ab initio study of holmium nanowires on a Ge(111) Surface
, 2007 A nanorod structure has been observed on the Ho/Ge(111) surface using scanning tunneling microscopy (STM). The rods do not require patterning of the surface or defects such as step edges in order to grow as is the case for nanorods on Si(111).

Limnology and Oceanography: Methods, EarlyView.Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Triple-Clad Fiber Combiner for Holmium-Doped Fiber Lasers Clad-Pumping
PhotonicsThe development of a high-power 7 × 1 triple-clad fiber combiner aimed at resonantly clad-pump holmium-doped fiber lasers is presented. Thanks to the implementation in the combiner of a low refractive index glass capillary, we show that the developed ...

Dysprosium-doped ZBLAN fiber laser tunable from 2.8 {\mu}m to 3.4 {\mu}m, pumped at 1.7 {\mu}m
, 2018 We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 {\mu}m Raman fiber laser. To the best of our knowledge, this represents the largest tuning range achieved to date from

UroPrecision, EarlyView.Abstract Surgical intervention for benign prostatic hyperplasia (BPH) can lead to postoperative stress urinary incontinence. Pelvic floor muscle exercises (PFME) are proposed as a non‐invasive strategy to mitigate symptoms, but their efficacy and optimal timing remain unclear.
