Self‐Adhesive Conductive Elastomers for Gel‐Free Biopotential Recording

open access: yesAdvanced Electronic Materials, EarlyView.
σPOMaC, a self‐adhesive conductive citrate elastomer incorporating PEDOT:PSS and DBSA, enables gel‐free biopotential electrodes with stable conductivity and intrinsic skin adhesion. The composite exhibits low resistivity (∼ 0.02 Ω·cm), robust electrical performance during repeated use, and reliable on‐body ECG acquisition comparable to Ag/AgCl ...

High‐Performance Noble‐Metal‐Free Perovskite Solar Cells Enabled by MoOX/Cr/Al Multilayer Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
Cost‐effective perovskite solar cells (PSCs) are developed using a noble‐metal‐free MoOX/Cr/Al multilayer electrode. The devices achieve a power conversion efficiency (PCE) of 25.6%, competitive with that of Au‐based devices (26.3%), and a 25.5 cm2 mini‐module shows 21.3% PCE.

Measurement of Vapor Liquid Equilibrium for Difluoromethane (R32) +Fluoroethane (R161) + 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf)

open access: yesZhileng xuebao, 2018
In the study, we focused on the vapor-liquid equilibrium property of the ternary system of R32+R161+R1234yf. The vapor–liquid equilibrium data was measured via a liquid-circulation apparatus at temperatures from 283.15 K to 323.15 K.

Food Tastes in the United States: Convergence or Divergence?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

Low Flammability Limit of Mixtures of Natural Refrigerants: Standards vs Theory

open access: yes, 2022
Natural refrigerants are being increasingly adopted by heat pump manufacturers. Heat pumps using flammable refrigerants need to satisfy charge limit requirements from standard IEC/EN 60335-2-40 and EN 378.

Does a Specialized Niche Market Vegetable Processor Enjoy Bargaining Power?

open access: yesAgribusiness, EarlyView.
ABSTRACT Agribusiness companies may achieve competitive advantage through specialization within niche markets. One such niche is the fresh‐cut fruit and vegetable market, which has been steadily growing in Germany. This study examines whether the specialization of a German fresh‐cut producer grants it with market power within this niche market.
