Selective and Precise Editing of Digital Polymers Through Parallel or Series Toehold‐Mediated Strand Displacement

Advanced Functional Materials, EarlyView.
A sequence‐encoded supramolecular construct containing two accessible toeholds is developed herein for enabling multiple editing operations. By introducing specific input strands, it is possible to selectively erase or rewrite digital content through parallel or series toehold‐mediated strand displacement (PTMSD or STMSD).

Reference Material Preparation of 143Nd/144Nd Isotope Ratio

Yankuang ceshi, 2017
143Nd/144Nd isotope ratio is the key for Sm-Nd isotope method. The 143Nd/144Nd isotope ratio of geological samples varies within a small range, and thus the 143Nd/144Nd isotope ratio analysis must be precise.

Fingerprint analysis of biological samples using ICP-MS and IR-MS [PDF]

, 2012
Atomic spectroscopy based analytical techniques can generate fingerprints encompassing the vast majority of elements found in the periodic table as well as ratios of their stable isotopes. These highly multivariate fingerprints have laid the foundation

Test of Einstein Equivalence Principle for 0-spin and half-integer-spin atoms: Search for spin-gravity coupling effects

, 2014
We report on a conceptually new test of the equivalence principle performed by measuring the acceleration in Earth's gravity field of two isotopes of strontium atoms, namely, the bosonic $^{88}$Sr isotope which has no spin vs the fermionic $^{87}$Sr ...

Advancing Electrochemical Nitrate Reduction: Overcoming Rate‐Limiting Bottlenecks with Copper/Cobalt Catalysts

Advanced Functional Materials, EarlyView.
This paper synthesizes CuO@CuCo2O4 catalysts via an emulsion hydrothermal method. Among them, CuCuCo2O4 perfectly inherits the advantages of CuO and Co3O4 and successfully connects the reactions in series. During the electrolysis process, CuO is reduced to Cu.

Liquid Metals as Initiators of Free‐Radical Polymerization of Hydrogels: A Perspective

Advanced Functional Materials, EarlyView.
Gallium‐based liquid metals initiate free radical polymerization to form hydrogels without the use of toxic molecular initiators. In addition to initiating polymerization, they can act as crosslinkers, yielding softer, more extensible, and tougher hydrogels than those formed with conventional initiators.

Phase‐Stable Palladium Hydride Derived from PdCoO2 for Sustainable Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
The exceptionally active β‐PdHx is demonstrated for the hydrogen evolution reaction in acidic media. The fast activation kinetics from the PdCoO2 template are resolved by operando spectroscopy, and isotope‐labeled atom probe tomography quantifies the H content in β‐PdHx. The outstanding stability of the electrocatalyst is attributed to the retention of
