Formation of Chiral alpha-Monofluorinated-beta-amino Esters through Organocatalytic Asymmetric Reduction of alpha-Fluoro-beta-enamino Esters by Trichlorosilane

open access: yes, 2012
A concise method was developed to prepare chiral alpha-monofluorinated-beta-amino esters through N-sulfinyl urea catalyzed asymmetric hydrosilylation of alpha-fluoro-beta-enamino esters, which affords high yields, good to high diastereoselectivities (up ...

Multimodal Optoelectronic Synapses for Neuromorphic Intelligence: Coupling Light, Electrical, Thermal, and Beyond

open access: yesAdvanced Functional Materials, EarlyView.
This review revisits optoelectronic neuromorphic devices that extend from unimodal sensing toward multimodal perception. Five types of stimuli‐to‐output information flow that are classified based on the device roles within the system and applications are summarized and discussed.

Non-catalytic Synthesis of Biolubricant Esters and their Solubilities in Supercritical Fluids [PDF]

open access: yes, 2018
Breakdown products released due to increased loss of mineral oil based lubricants to the environment lead to aquatic toxicity and release of harmful volatile compounds into the atmosphere. The production of these conventional mineral oil based lubricants

Programming Nanoscale Reaction Environments via Peptide Localization for Gold Nanoparticle Growth in Liposomal Nanoreactors

open access: yesAdvanced Functional Materials, EarlyView.
The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

open access: yesAdvanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Esters in Australian geranium oil (Pelargonium hybrid)

open access: yes, 1999
This paper is the first detailed report of straight chain and branched esters in Australian geranium oil. Hydrodistillation of 41 samples of Australian-grown rose geranium (Pelargoniun hybrid) produced oils containing four detectable parent alcohols; 2 ...

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

open access: yesAdvanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...
