Indirect calorimetry and nutritional problems in clinical practice

open access: yes, 2001
Indirect calorimetry is a simple and affordable tool for measuring energy expenditure and for quantifying the utilization of macronutrients. Its use is becoming increasingly widespread, but it is necessary to know its methodological features and its ...

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

open access: yesAdvanced Science, EarlyView.
Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for

Chiral Supramolecular Templating Enables Tunable Second‐Harmonic Generation in Hybrid Zinc Thiocyanates

open access: yesAngewandte Chemie, EarlyView.
Chiral supramolecular templates derived from natural amino acids direct the spatial organization of SHG‐active [Zn(SCN)4]2− units, enabling diverse second‐harmonic generation in hybrid zinc thiocyanates. ABSTRACT Chiral organic molecules have been widely used to construct hybrid nonlinear optical (NLO) materials with second‐harmonic generation (SHG ...

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

open access: yesAdvanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Reinforcing Particle Architectural Stability of Li‐Rich Cathode With Enhanced Anionic Redox Reaction Reversibility

open access: yesAngewandte Chemie, EarlyView.
In this work, we establish a direct correlation between internal compactness and particle architectural stability, identifying it as a key descriptor of cathode structural integrity. Simultaneously, the capacity contribution and compensation mechanism of ARR are resolved, revealing that the extent of irreversible capacity loss is governed by both the ...
