A Single-Molecular AND Gate Operated with Two Orthogonal Switching Mechanisms.

Advanced materials (Deerfield Beach, Fla.)

Zhang N, Lo WY, Jose A, Cai Z, Li L, Yu L.
PMID: 28512786
Adv Mater. 2017 Jul;29(28). doi: 10.1002/adma.201701248. Epub 2017 May 17.

Single-molecular electronics is a potential solution to nanoscale electronic devices. While simple functional single-molecule devices such as diodes, switches, and wires are well studied, complex single-molecular systems with multiple functional units are rarely investigated. Here, a single-molecule AND logic...

Terahertz and mid-infrared plasmons in three-dimensional nanoporous graphene.

Nature communications

D'Apuzzo F, Piacenti AR, Giorgianni F, Autore M, Guidi MC, Marcelli A, Schade U, Ito Y, Chen M, Lupi S.
PMID: 28345584
Nat Commun. 2017 Mar 27;8:14885. doi: 10.1038/ncomms14885.

Two-dimensional (2D) graphene emerged as an outstanding material for plasmonic and photonic applications due to its charge-density tunability, high electron mobility, optical transparency and mechanical flexibility. Recently, novel fabrication processes have realised a three-dimensional (3D) nanoporous configuration of high-quality...

Alterations in expressed prostate secretion-urine PSA N-glycosylation discriminate prostate cancer from benign prostate hyperplasia.

Oncotarget. 2017 Aug 16;8(44):76987-76999. doi: 10.18632/oncotarget.20299. eCollection 2017 Sep 29.

The prostate specific antigen (PSA) test is widely used for early diagnosis of prostate cancer (PCa). However, its limited sensitivity has led to over-diagnosis and over-treatment of PCa. Glycosylation alteration is a common phenomenon in cancer development. Different PSA...

Rational Design of Porous Conjugated Polymers and Roles of Residual Palladium for Photocatalytic Hydrogen Production.

Journal of the American Chemical Society

Developing highly efficient photocatalyts for water splitting is one of the grand challenges in solar energy conversion. Here, we report the rational design and synthesis of porous conjugated polymer (PCP) that photocatalytically generates hydrogen from water splitting. The design...

PMID: 26041586
Nat Commun. 2015 Jun 04;6:7327. doi: 10.1038/ncomms8327.

The integration of multiple materials with complementary absorptions into a single junction device is regarded as an efficient way to enhance the power conversion efficiency (PCE) of organic solar cells (OSCs). However, because of increased complexity with one more...

The organocatalytic asymmetric Prins cyclization.

Angewandte Chemie (International ed. in English)

Tsui GC, Liu L, List B.
PMID: 26015083
Angew Chem Int Ed Engl. 2015 Jun 22;54(26):7703-6. doi: 10.1002/anie.201500219. Epub 2015 May 26.

We describe here the design and development of an organocatalytic Prins cyclization. In the presence of a confined chiral imidodiphosphoric acid catalyst, salicylaldehydes react with 3-methyl-3-buten-1-ol to afford highly functionalized 4-methylenetetrahydropyrans in excellent regio- and enantioselectivity. The extreme steric...

A Graph-Embedding Approach to Hierarchical Visual Word Mergence.

IEEE transactions on neural networks and learning systems

IEEE Trans Neural Netw Learn Syst. 2017 Feb;28(2):308-320. doi: 10.1109/TNNLS.2015.2509062. Epub 2016 Jan 05.

Appropriately merging visual words are an effective dimension reduction method for the bag-of-visual-words model in image classification. The approach of hierarchically merging visual words has been extensively employed, because it gives a fully determined merging hierarchy. Existing supervised hierarchical...

Sigma(54) (σ(54)) regulates nitrogen and carbon utilization in bacteria. Promoters that are σ(54)-dependent are highly conserved and contain short sequences located at the -24 and -12 positions upstream of the transcription initiation site. σ(54) requires regulatory proteins known as...
