Comments on "Wall-plug (AC) power consumption of a very high energy e+/e- storage ring collider" by Marc Ross

open access: yes, 2013
The paper arXiv:1308.0735 questions some of the technical assumptions made by the TLEP Steering Group when estimating in arXiv:1305.6498 the power requirement for the very high energy e+e- storage ring collider TLEP.

Core‐Shell: Resolving the Dilemma of Hard Carbon Anodes by Sealing Nanoporous Particles With Semi‐Permeable Coatings

open access: yesAngewandte Chemie International Edition, EarlyView.
A core–shell strategy is presented to overcome the high first‐cycle losses of non‐graphitic hard carbon anodes. Activated carbon is sealed by gas‐phase carbon deposition to create semi‐permeable shells that spatially separate SEI formation from Na storage in a retained nanoporous core. The resulting anode delivers 400 ± 24 mAh g−1 with an ICE of 82 ± 2%

Periodic and Statistically Distributed Surface Texturing of Surface‐Enhanced Raman Spectroscopy (SERS) Sensors with Spatially Selective Signal Mapping

open access: yesAdvanced Physics Research, EarlyView.
Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.

D’où vient la dégradation du solde commercial français hors énergie ? Une analyse par types de produits. [PDF]

open access: yes
La contraction du solde hors énergie français depuis 2002 provient, avant tout, de l’automobile et des produits électroniques grand public. Cette évolution a été amplifi ée par la contre-performance de produits qui concourent habituellement à tirer vers ...

Enhancing the Capacitance of Poly(Heptazine Imide) Electrodes in Aqueous Electrolytes via Hybrid Material Design

open access: yesBatteries &Supercaps, EarlyView.
This work highlights the synthesis of a potassium poly(heptazine imide) K‐PHI@carbon hybrid material. The design of the hybrid improves the electrochemical properties of the semiconducting carbon nitride enabling the investigation of interaction between K‐PHI and different cations from the electrolyte.

Transforming Coal Waste into Surface‐Engineered Carbons for Lithium–Sulfur Batteries

open access: yesBatteries &Supercaps, EarlyView.
Coal waste is transformed into surface‐engineered porous carbons that suppress polysulfide shuttling and boost Li–S battery performance. Slow redox kinetics and polysulfide shuttling hinder the practical deployment of lithium–sulfur (Li–S) batteries.
