Reduced‐Graphene Oxide Nanofiltration Membranes Intercalated by Conjugated Polyaromatics: Towards High Monovalent Salt Rejections

open access: yesAdvanced Science, EarlyView.
We demonstrate the fabrication of a series of reduced‐GO nanofiltration membranes containing intercalated polyaromatic conjugated molecules of different structural classes. These tuned‐nanochannel membranes perform “deep nanofiltration” with remarkably high monovalent salt rejections and near‐total divalent salt rejections in a large concentration ...

Unspanned Stochastic Volatility and the Pricing of Commodity Derivatives [PDF]

open access: yes
We conduct a comprehensive analysis of unspanned stochastic volatility in commodity markets in general and the crude-oil market in particular. We present model-free results that strongly suggest the presence of unspanned stochastic volatility in the ...

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery

open access: yesAdvanced Science, EarlyView.
We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent

Cointegration and Causality Analysis of World Vegetable Oil and Crude Oil Prices [PDF]

open access: yes
Because of the recent soaring petroleum price and growing environmental concerns, biodiesel has become an important alternative fuel. Biodiesel is the mono alky esters made from a vegetable oil, such as soybean or rapeseed oil, or sometimes from animal ...

Forecasting the term structure of crude oil futures prices with neural networks

open access: yes, 2015
The paper contributes to the rare literature modeling term structure of crude oil markets. We explain term structure of crude oil prices using dynamic Nelson-Siegel model, and propose to forecast them with the generalized regression framework based on ...

Constraint of Lignin–Carbohydrate Complex Orchestrated on Polyphenol in Oil–Water Interface Targeting Ulcerative Colitis Therapy

open access: yesAdvanced Science, EarlyView.
This study constructed the W1/O/W2 emulsion–based targeted therapy delivery system for ulcerative colitis (UC) utilizing LCC as surfactant for the first time. This multifunctional emulsion offered certain therapeutic advantages for UC, including targeted colonic delivery of active compounds, synergistic modulation of gut microbiota through combined ...
