Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Bacterial reduction of N-oxides of tobacco- specific nitrosamines (TSNA) [PDF]

open access: yes, 1996
1 Contrary to established metabolic pattern, a recent investigation of NNK metabolism produced in rat urine higher levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1- butanone (NNK) and 4-(methylnitrosamino)-1-(3-pyri dyl)-1-butanol (NNAL) than their N ...

A theory for the tissue specificity of BRCA1/2 related and other hereditary cancers [PDF]

open access: yes, 2010
Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery. There has been much conjecture to explain such apparently

Green Solvent Enabled Perovskite Ink for Ambient‐Air‐Processed Efficient Inkjet‐Printed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
This study explores an eco‐friendly solvent with 1,3‐dimethyl‐2‐imidazolidinone for developing perovskite ink, enhancing grain size and formation of purer phase perovskite. The inkjet‐printed perovskite solar cells demonstrated a remarkable improvement in device power conversion efficiency from 14.6% to almost 17.8%, highlighting sustainable innovation
