Comparison of acetone–butanol–ethanol fermentation and ethanol catalytic upgrading as pathways for butanol production: A techno-economic and environmental assessment [PDF]

Biofuel Research Journal, 2021
Butanol is an important compound used as a building block for producing value-added products and an energy carrier. The main butanol production pathways are conventional acetone–butanol–ethanol (ABE) fermentation and catalytic upgrading of ethanol.

Modeling and tuning of glucose oxidase‐catalase system incorporating dissolved oxygen concentration

Journal of Chemical Technology &Biotechnology, Volume 98, Issue 6, Page 1520-1531, June 2023., 2023
Abstract BACKGROUND Gluconic acid production by a glucose oxidase (GOx) and catalase (CAT) system has been proposed. However, the bioprocess optimal design and operation are limited by the lack of kinetic models of GOx involving oxygen as substrate. Herein, the GOx‐CAT system is modeled considering a continuous oxygen supply at a bioreactor lab scale ...

Recovery of insular seabird populations years after rodent eradication

Conservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Seabirds have been particularly affected by invasive non‐native species, which has led to the implementation of numerous eradication campaigns for the conservation of these keystone and highly vulnerable species. Although the benefits of eradication of invasive non‐native species for seabird conservation have been demonstrated, the recovery ...

UNDERSTANDING GRAY ZONE WARFARE FROM MULTIPLE PERSPECTIVES

World Affairs, Volume 186, Issue 1, Page 81-104, Spring 2023., 2023
This study examines the dynamics of gray zone warfare by analyzing its conceptualization in the literature and through its practice in several recent examples. Ever‐increasing changes in the characteristics of contemporary warfare have complicated the security environment of the 21st century.

Precisely spun super rotors

Nature Communications, 2021
Optical pulses can be useful to create and control molecules in higher quantum states. Here the authors use optical pumping to create rotationally excited states of SiO+ molecular ion into super rotor ensemble.

Fluorescence Intensity Ratio‐based temperature sensor with single Nd3 + :Y2O3 nanoparticles: Experiment and theoretical modeling

Nano Select, Volume 2, Issue 2, Page 346-356, February 2021., 2021
A thermometer based on single Nd3 + :Y2O3 nanoparticles is reported. It relies on the ratio of thermally coupled Nd3 + emission lines accessible by continuous‐wave upconversion under 880 nm or downconversion under 532 nm. The rate equation analysis lead to results that nicely agree with the experimental data. The system showed a relative sensitivity up

Percutaneous radiofrequency‐assisted liver partition versus portal vein embolization before hepatectomy for perihilar cholangiocarcinoma

BJS Open, Volume 4, Issue 1, Page 101-108, February 2020., 2020
Percutaneous radiofrequency‐assisted liver partition with portal vein embolization in staged liver resection (PRALPPS), modIfied ALPPS with reduced surgical trauma on the first stage, was used in 11 patients with perihilar cholangiocarcinoma. PRALPPS did not differ from portal vein embolization (PVE) in terms of morbidity or mortality.
