A multifunctional tumor-targeting delivery system was developed and evaluated for an efficient treatment of drug-resistant ovarian cancer by combinatorial therapeutic modality based on chemotherapy and mild hyperthermia. The engineered iron oxide nanoparticle (IONPs)-based nanocarrier served as an efficient delivery vehicle for doxorubicin and provided the ability to heat cancer cells...
Air-sea interaction at ocean fronts and eddies exhibits positive correlation between sea surface temperature (SST), wind speed, and heat fluxes out of the ocean, indicating that the ocean is forcing the atmosphere. This contrasts with larger scale climate modes where the negative correlations suggest that the atmosphere is driving the...
Mud volcanoes (MVs) are considered as important methane (CH₄) sources for the
atmosphere; gas is not only released from macroseepage, i.e., from craters and visible gas bubbling
manifestations, but also from invisible and pervasive exhalation from the ground, named miniseepage.
CH₄ flux related to miniseepage was measured only in a...
We demonstrate terahertz (THz) imaging and spectroscopy of single-layer graphene deposited on an intrinsic Si substrate using THz time-domain spectroscopy. A single-cycle THz pulse undergoes multiple internal reflections within the Si substrate, and the THz absorption by the graphene layer accumulates through the multiple interactions with the graphene/Si interface. We...
Asukamycin, a member of the manumycin family of antibiotics, exhibits strong antibacterial, antifungal, and anti-neoplastic activities. However, its production in the wild-type strain of Streptomyces nodosus subsp. asukaensis ATCC 29757 is relatively low. Recently, the biosynthetic gene cluster for asukamycin was identified in the producing organism and among the 36...
The wind speed response to mesoscale SST variability is investigated over the Agulhas Return Current region of the Southern Ocean using the Weather Research and Forecasting (WRF) Model and the U.S. Navy Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS) atmospheric model. The SST-induced wind response is assessed from eight simulations with...
Yutian (Cry to Heaven) is the third Chinese stage adaptation of Harriet Beecher Stowe’s novel Uncle Tom’s Cabin between 1907 and 2007. The first, Heinu yutian lu (Black Slave’s Cry to Heaven) by Zeng Xiaogu, was staged by Chinese students in Tokyo in 1907; the second, Heinu hen (Regret of...
Suspended metallic carbon nanotubes (m-CNTs) exhibit a remarkably large transport gap that can exceed 100 meV. Both experiment and theory suggest that strong electron-electron interactions play a crucial role in generating this electronic structure. To further understand this strongly-interacting system, we have performed electronic measurements of suspended m-CNTs with known...
High spatiotemporal resolution satellite imagery is useful for natural resource management and monitoring for land-use and land-cover change and ecosystem dynamics. However, acquisitions from a single satellite can be limited, due to trade-offs in either spatial or temporal resolution. The spatial and temporal adaptive reflectance fusion model (STARFM) and the...
We introduce a novel ambient hydrolysis deposition (AHD) methodology that, for the first time, employs sequential water adsorption followed by a hydrolysis reaction to infiltrate tiny SnO2₂ particles inside nanopores of mesoporous carbon in a conformal and controllable manner. The empty space in the SnO2₂/C composites can be adjusted by...
