Development of ZnO Buffer Layers for As‐Doped CdSeTe/CdTe Solar Cells with Efficiency Exceeding 20%

open access: yesAdvanced Materials Technologies, EarlyView.
Highly resistive ZnO has been used as the buffer layer in As‐doped CdSeTe/CdTe solar cells to achieve efficiencies higher than 20%. STEM images and EDX mapping show that the quality of the front interface is dependent on the ZnO deposition temperature. Unusually, chlorine is not observed at the front interface using EDX when the ZnO is deposited at 100

A Protocol Using Compact 3D Printed Micro‐Optical Elements for Protein Identification from Low‐Intensity Amino‐Acid Raman Signals

open access: yesAdvanced Materials Technologies, EarlyView.
High speed Raman spectroscopy has various applications, e.g. the sequencing of proteins. However, low signal intensity coincides with the low measurement time. The study presents a protocol using only a small number of sensitive single‐photon detectors measuring optimized spectral regions.

Multidrug Resistance Protein-4 Influences Aspirin Toxicity in Human Cell Line

open access: yesMediators of Inflammation, 2015
Overexpression of efflux transporters, in human cells, is a mechanism of resistance to drug and also to chemotherapy. We found that multidrug resistance protein-4 (MRP4) overexpression has a role in reducing aspirin action in patients after bypass ...

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Flexible framework of computing binding free energy using the energy representation theory of solution [PDF]

open access: yesarXiv
Host-guest binding plays a crucial role in the functionality of various systems, and its efficiency is often quantified using the binding free energy, which represents the free-energy difference between the bound and dissociated states. Here, we propose a methodology to compute the binding free energy based on the energy representation (ER) theory of ...
