Astrocyte‐Guided Maturation of Neural Constructs in a Modular Biosynthetic Hydrogel for Biohybrid Neurotechnologies

open access: yesAdvanced Functional Materials, EarlyView.
A modular biosynthetic PVA–gelatin hydrogel crosslinked via visible‐light thiol‐ene chemistry is engineered as a coating for neural electrodes. Optimizing matrix composition and mechanical properties enables the hydrogel to support astrocytic populations that guide neural differentiation and functional maturation.

Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

open access: yesAdvanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Studies on the Estimation of Pregnancy Rate of White Hanwoo (Albino Korean Native Cattle) with Sexed Semen

open access: yesJournal of Animal Reproduction and Biotechnology, 2015
The purpose of this study is to produce wanted sex progeny of genetically confined White Hanwoo (albinism) with preselected sex sperm. One bull of White Hanwoo was chosen for semen donor and X sperm was sorted by MoFlo XDP cell sorter.

State and parameter estimation approach to monitoring AGR nuclear core [PDF]

open access: yes, 2007
This work concerns with the problem of monitoring an Advanced Gas-cooled Nuclear Reactor (AGR) core. This plant (figure 1) makes use of the heat given by the nuclear efficient reaction to produce electricity by means of steam turbines.

Self‐Feeding of Engineered Tissues via Controlled Glucose Release Facilitates Survival and Vascularization of Living Implants

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Engineering living matter has great clinical potential to deliver functional replacement organs. However, clinical translation remains hampered by the current inability to maintain viability of clinically relevant‐sized constructs. During the pre‐vascular phase, implants rely on nutrient diffusion for survival, which is insufficient at ...

Efficiency of In Vivo Embryo Production following Superovulation with Sex-soted Semen in Hanwoo (Korean Native Cattle)

open access: yesJournal of Animal Reproduction and Biotechnology, 2014
Sexed semen is commonly used for the production of calves of the desired gender. Gender selection is important in animal production industries. For example, female cattle are required for the dairy industry while males are preferred in the beef cattle ...

Gold Nanoclusters as Dual Agents for Engineering Tumor Vascular Leakiness and Performing Photothermal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Many cancer nanotherapeutics, while potent, suffer from the inability to escape from the tumor vasculature, especially in the absence of endothelial permeability. In this work, ultrasmall gold nanoclusters could engineer nanomaterials induced endothelial leakiness (NanoEL) and harness strong NIR induced photothermal characteristics to suppress tumor ...
