Water confined to channels one nanometer thick exhibits electrochemicalbehavior distinct from bulk water, including enhanced protonic conductivityand large dielectric anisotropy.Here, we exploit these characteristics to designa scalable electrochemical energy storage system-a “blue capacitor”-constructedentirely from naturally abundant materials. By assembling layeredclays and conductive graphene, we produce 1-nm-thick channels in whichconfined water acts as the sole electrolyte. [...]

One of the most common resistance mechanisms against antibiotics employed by Gram-negative bacteria involves the production of β-lactamases, resulting in rapid hydrolysis of the antibiotic. Extensive use of the early-generation cephalosporins led to the rise of extended-spectrum β-lactamases such as CTX-Ms [...]

The all-germanium adamantane (Me$_3$SiGe)$_4$(GeMe$_2$)$_6$ (2) was synthesized from its isomer (Me$_3$GeSi)$_4$(GeMe$_2$)$_6$ (1) via sila-Wagner-Meerwein rearrangement (overall four steps starting from commercial Me$_2$GeCl$_2$, Si$_2$Cl$_6$, and [nBu$_4$N]Cl). The molecular structures of 1 and 2 were characterized by single-crystal X-ray diffraction; a plausible mechanistic scenario is postulated based on quantum-chemical calculations..

Measurements of properties of top quark-antiquark pair production in association with a W boson in proton-proton collisions at a center-of-mass energy of 13 TeV are presented, using a data sample corresponding to an integrated luminosity of 138 fb$^{−1}$, recorded by the CMS experiment at the CERN LHC. Events are selected based on the presence of either two leptons with the same electric charge or three leptons, and multiple jets and b-tagged jets [...]

At hadron colliders, the net transverse momentum of particles that do not interact with the detector (missing transverse momentum, $\vec{p}_\mathrm{T}^\text{miss}$) is a crucial observable in many analyses. In the standard model, $\vec{p}_\mathrm{T}^\text{miss}$ originates from neutrinos. [...]

This Letter reports the first measurement of photonuclear D$^0$ meson production in ultraperipheral heavy ion collisions. The study is performed using lead-lead collision data, with an integrated luminosity of 1.38 nb$^{-1}$, collected by the CMS experiment at a nucleon-nucleon center-of-mass energy of 5.36 TeV. [...]

A model-independent measurement of the differential production cross section of the Higgs boson decaying into a pair of W bosons, with a final state including two jets produced in association, is presented. In the analysis, events are selected in which the decay products of the two W bosons consist of an electron, a muon, and missing transverse momentum [...]

Precision measurements of Higgs boson differential production cross sections are a key tool to probe the properties of the Higgs boson and test the standard model. New physics can affect both Higgs boson production and decay, leading to deviations from the distributions that are expected in the standard model [...]

Constraints on Wilson coefficients (WCs) corresponding to dimension-6 operators of the standard model effective field theory (SMEFT) are determined from a simultaneous fit to seven sets of CMS measurements probing Higgs boson, electroweak vector boson, top quark, and multijet production. Measurements of electroweak precision observables are also included and provide complementary constraints to those from the CMS experiment. [...]
