Recent Research Progress on Lead-free or Less-lead Perovskite Solar Cells

International Journal of Electrochemical Science, 2017
Perovskite solar cells (PSCs) have been attracting great research interests and attained remarkable progress since its debut in 2009. Remarkably, the power conversion efficiency (PCE) of PSCs has already surpassed other types of solar cells that have ...

Lagrange inversion formula, Laguerre polynomials and the free unitary Brownian motion

, 2016
This paper is devoted to the computations of some relevant quantities associated with the free unitary Brownian motion. Using the Lagrange inversion formula, we first derive an explicit expression for its alternating star cumulants of even lengths and ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Better bullets to shoot small mammals without poisoning scavengers

Wildlife Society Bulletin, 2017
Recreational shooters kill millions of small mammals each year and scavengers that ingest the carcasses can be poisoned if lead bullets are used.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Influence of electric field on the Eu+3 photolumiscence in lead-free ferroelectric Na1/2Bi1/2TiO3

, 2015
Eu modified Na1/2Bi1/2TiO3 (NBT) was investigated for electric-field induced Eu+3 photoluminescence (PL) and structural changes. Detailed analysis revealed that below a critical Eu composition electric field irreversibly suppresses the structural ...

Whisker Test of Lead-Free Semiconductor Packages in Lead-Free Soldering

Journal of Japan Institute of Electronics Packaging, 2010
We evaluated the semiconductor mounting substrate and investigated the whisker's generations and factors by experimenting different environmental conditions. On the lead consisted of Cu base/Sn plating, the result of the condition 110°C/85% & 120°C/85% which were produced by Air-HAST (HAST with air) generates Sn whiskers faster than other high ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
