Organic chemistry is the study of the synthesis, structure, reactivity and properties of the diverse group of chemical compounds primarily constructed of carbon. All life on earth is carbon-based ...

A series of homoleptic tetravalent transition-metal and actinide Schiff-base coordination complexes, ML2 {M = Zr, Hf, Th, U; L = N,N′-bis[(4,4′-diethylamino)salicylidene]-1,2-phenylenediamine}, have ...

Rational construction of covalent organic frameworks (COFs) with novel structures still remains a challenge. Herein, we report the designed synthesis of two COFs, 2D-BPTA-COF and 3D-BMTA-COF, starting ...

Cellulosic insulating paper is the essential component of the insulation in power transformers. Under the thermal stress inside the transformer, the cellulosic insulating paper degrades and generates ...

Enantioselective copper(I) hydride (CuH)-catalyzed hydroamination has undergone significant development over the past several years. To gain a general understanding of the factors governing these ...

2-(Trityliminomethyl)-quinolin-8-ol (HL) and its Zn(II) complex were synthesized and characterized by single-crystal X-ray diffraction. HL is an unsymmetrical molecule and coordinated with Zn(II) ion ...

We describe an automated system for high-resolution profiling of human mitochondrial DNA (mtDNA) based upon multiplexed polymerase chain reaction (PCR) followed by desolvation and direct analysis ...

Photooxygenations of 1,2-, 1,3-, and 2,3-di- and 1,2,3-trisubstituted indolizines 1a−1f under different reaction conditions in methanol and acetonitrile have been investigated to establish the general ...

Successive voltage drops near the holding voltage associated with sequential finger triggering (SFT) are observed in multi-finger floating-base SCRs. A time delay between the triggering of neighboring ...

In this study, a composite of pond mud and lanthanum- and nano-zero valent iron-modified-biochar was investigated for its ability to adsorb methylene blue (MB) and sulfamethazine (SMZ). La-modified ...

Although separation of single-walled carbon nanotubes (SWCNTs) according to their helicity and handedness has been attracting tremendous interest recently, exploration of the left- and right-handed ...
