DC-Link Voltage Control of a Grid-Connected Solar Photovoltaic System for Fault Ride-Through Capability Enhancement

open access: yesApplied Sciences, 2019
The high penetration level of solar photovoltaic (SPV) generation systems imposes a major challenge to the secure operation of power systems. SPV generation systems are connected to the power grid via power converters.

Solar PV-BES in distribution system with novel technique for DC voltage regulation

open access: yesEngineering Science and Technology, an International Journal, 2020
The incremental penetration of solar photovoltaic (SPV) is creating voltage related issues in the distribution system. The problem gets complicated during the peak load demand and peak generation from SPV.

In-House Counsel’s Role in the Structuring of Mortgage-Backed Securities [PDF]

open access: yes, 2012
The authors introduce the financial crisis and the role played by mortgage-backed securities. Then describe the controversy at issue: whether, in order to own and enforce the mortgage loans backing those securities, a special-purpose vehicle “purchasing”

Dynamic Hydrogen‐Bonding Nanonetworks and Asymmetric Dual‐Interface Built‐In Electric Fields Cooperatively Mediate Proton‐Coupled Electron Transfer for C─H Activation

open access: yesAdvanced Science, EarlyView.
The general strategy for constructing proton–electron dual‐transport‐channel photocatalysts (hollow Co3S4/Sv‐chalcogenide/Ti3C2 nanoreactors) is developed. Theses ternary‐component nanoreactors feature dynamic hydrogen‐bonding nanonetworks as proton‐transport channels and asymmetric dual‐interface BIEFs as electron‐transport channels, serving as a ...

Mathematical Modeling and Evaluation of Performance Characteristics of a Hybrid Solar PV and Wind Energy System

open access: yesJournal of Applied Science and Engineering, 2022
Solar Photovoltaic (SPV) and wind energy are two major sources of renewable energy that are intermittent in nature. A hybrid system consisting of SPV and Wind Energy Conversion System (WECS) can meet the energy needs as either of the sources continues to

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

open access: yesAdvanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Tracking surface photovoltage dipole geometry in bi2se3 with time-resolved photoemission [PDF]

open access: yes, 2019
Topological insulators have been shown to exhibit strong and long-lived surface photovoltages when excited by an infrared pump. The ability to generate long-lived potentials on these surfaces provides opportunities to manipulate the spin-momentum locked ...

Prognostic Significance of Portal Vein Tumor Thrombus in Pancreatic Ductal Adenocarcinoma Treated With Chemoradiotherapy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Aim To examine the significance of portal vein tumor thrombus (PVTT) as a prognostic factor for patients with pancreatic ductal adenocarcinoma (PDAC) treated with chemoradiotherapy (CRT) followed by surgery. Methods The study retrospectively examined 313 patients with borderline resectable (BR) or locally advanced (LA) PDAC who underwent CRT ...
