Determination of Metals Content in Wine Samples by Inductively Coupled Plasma-Mass Spectrometry
Molecules, 2018 Knowledge about the metal content of wine is very important, for many reasons. Depending on the element, its quantity varies in wine from ng/L to mg/L.

Matrix Effects in Inductively Coupled Plasma Mass Spectrometry
Analytical Sciences, 1987 Suppression of analyte signals by various concomitant elements was investigated. In addition to the ionization interference by easily ionizable elements reported previously, signal suppression by heavy matrix elements was found to be significant. The interference trend followed the order of atomic weight of the matrix elements, i.e., the larger the ...

A Universal van der Waals Tunneling Injector for Monolayer CMOS
Advanced Materials, EarlyView.A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Advanced Materials, EarlyView.A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis
Advanced Materials, EarlyView.A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...
