Biomass‐Derived Carbon and Their Composites for Supercapacitor Applications: Sources, Functions, and Mechanisms

open access: yesEcoEnergy, EarlyView.
Carbon materials derived from biomass are sustainable and environmentally friendly, making them ideal for electrochemical energy storage and conversion. This review explores nanocomposites utilizing biomass‐derived carbon with MXenes, metal‐organic frameworks (MOFs), graphene, conductive polymers, and transition metal oxides/hydroxides, highlighting ...

Black holes and D-branes [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1998
D-branes have been used to describe many properties of extremal and near extremal black holes. These lecture notes provide a short review of these developments.

Effects of Chatting Styles on Sharers’ Emotions During Online Conversations

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Prior social sharing research suggests that cueing sharers to focus on recounting emotionally arousing details of a negative experience often increases negative affect, whereas cueing them to reconstrue the experience leads to emotional recovery.

Non-Abelian black holes in string theory

open access: yesJournal of High Energy Physics, 2017
We study a family of 5-dimensional non-Abelian black holes that can be obtained by adding an instanton field to the well-known D1D5W Abelian black holes. Naively, the non-Abelian fields seem to contribute to the black-hole entropy but not to the mass due

When D-branes break

open access: yesPhysics Letters B, 2006
We analyze the possible configurations of D-branes breaking on other D-branes. We describe these configurations in the context of a brane-antibrane effective theory in two ways. First as a tachyon configuration representing a non-trivial bundle over the sphere surrounding the end of the brane a la Polchinski, and second in terms of tachyon solitons ...

Performance‐Emission Optimization of a Diesel Engine Blended With Biodiesel and Pentanol

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The quest for novel alternative fuel blends is fueled by the urgent need to address the inadequacy of fossil fuels and the escalating environmental concerns. While previous studies have primarily explored base fuel and minimally diluted alcohol content since the late 20th century, a significant research gap exists in the comparative analysis ...

Anomalous U(1) gauge bosons as light dark matter in string theory

open access: yesPhysics Letters B, 2020
Present experiments are sensitive to very weakly coupled extra gauge symmetries which motivates further investigation of their appearance in string theory compactifications and subsequent properties.

Non-supersymmetric D-branes with vanishing cylinder amplitudes in asymmetric orbifolds

open access: yesJournal of High Energy Physics, 2017
We study the type II string vacua with chiral space-time SUSY constructed as asymmetric orbifolds of torus and K3 compactifications. Despite the fact that all the D-branes are non-BPS in any chiral SUSY vacua, we show that the relevant non-geometric ...

Highland Barley‐Derived Polyphenols: A Category of Bioactive Phytochemicals Beneficial for Intestinal Health

open access: yesFood Chemistry International, EarlyView.
This minireview highlights that highland barley polyphenols (HBPPs) regulate gut microbiota and promote intestinal homeostasis through antioxidant/anti‐inflammatory activities, barrier reinforcement, and immune modulation, mediated by interactions among HBBPs, intestinal microbiota and intestinal cells.

Application of Ferulic Acid to Alleviate Chilling Injury of Banana Fruit by Regulating Redox, Phenylpropanoid, and Energy Metabolism

open access: yesFood Frontiers, EarlyView.
This study investigated the effect of ferulic acid (FA) on the cold tolerance of banana fruit under 6°C‐storage for 7 days. In comparison with control, 3 mM FA treatment significantly alleviated chilling symptoms of banana fruit by enhancing phenylpropanoid metabolism and maintaining redox and energy homeostasis. ABSTRACT Banana fruit is susceptible to
