Electronic structure of colloidal 2H-MoS2 mono- and bilayers determined by spectroelectrochemistry [PDF]

open access: yes, 2022
We investigate the electronic structure of mono- and bilayers of colloidal 2H-MoS2 nanosheets synthesized by wet-chemistry using potential-modulated absorption spectroscopy (EMAS), differential pulse voltammetry (DPV) and electrochemical gating (ECG ...

Giant enhancement of nonreciprocity in gyrotropic heterostructures

open access: yesScientific Reports, 2023
Nonreciprocity is a highly desirable feature in photonic media since it allows for control over the traveling electromagnetic waves, in a way that goes far beyond ordinary filtering.

Coarse and Fine Two-Stage Calibration Method for Enhancing the Accuracy of Inverse Finite Element Method

open access: yesSensors, 2023
The inverse finite element method (iFEM) is a novel method for reconstructing the full-field displacement of structures by discrete measurement strain. In practical engineering applications, the accuracy of iFEM is reduced due to the positional offset of

Beyond the Document: A Single‐Center Qualitative Study of Survivorship Care Plan Barriers and Opportunities Across Pediatric Oncology Stakeholders

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivorship care plans (SCPs) summarize cancer treatment and guide risk‐based follow‐up for cancer survivors, yet remain difficult to create, share, and use. Stakeholder perspectives are needed to inform usable approaches.

Internal and external pressure in cubic perovskites: electronic structure effects and systematic accuracy from first principles

open access: yes, 2019
Pressure is an invaluable tool to manipulate properties of materials. Here, we present an in-depth theoretical study of the effect of structural variation on the electronic properties of cubic ABX3 perovskites where A  =  Cs, CH3NH3, B  =  Pb, Sn and X  =

Imaging the crystal orientation of 2D transition metal dichalcogenides using polarization-resolved second-harmonic generation

open access: yesOpto-Electronic Advances, 2019
We use laser-scanning nonlinear imaging microscopy in atomically thin transition metal dichalcogenides (TMDs) to reveal information on the crystalline orientation distribution, within the 2D lattice. In particular, we perform polarization-resolved second-

Third Harmonic Generation microscopy distinguishes malignant cell grade in human breast tissue biopsies

open access: yesScientific Reports, 2020
The ability to distinguish and grade malignant cells during surgical procedures in a fast, non-invasive and staining-free manner is of high importance in tumor management.

Impact of Pre-Patterned Structures on Features of Laser-Induced Periodic Surface Structures

open access: yesMolecules, 2021
The efficiency of light coupling to surface plasmon polariton (SPP) represents a very important issue in plasmonics and laser fabrication of topographies in various solids. To illustrate the role of pre-patterned surfaces and impact of laser polarisation

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Investigation on SMT Product Defect Recognition Based on Multi-Source and Multi-Dimensional Data Reconstruction

open access: yesMicromachines, 2022
The recognition of defects in the solder paste printing process significantly influences the surface-mounted technology (SMT) production quality. However, defect recognition via inspection by a machine has poor accuracy, resulting in a need for the ...
