3D Bioprinted Blood–Brain–Tumor Barrier Spheroid‐Based In Situ Evaluation of Anticancer Compounds Against Glioblastoma: ROS‐Producing Ruthenium as a Potential Therapeutic Candidate

open access: yesAdvanced Science, EarlyView.
The blood–brain–tumor barrier (BBTB) penetration by anticancer drugs and their effects on glioblastoma (GBM) is assessed using 3D bioprinted‐spheroids. Anticancer drug‐induced U‐87 MG cell death is quantified through in situ imaging of spheroids using a cancer cell death probe. The Ru compound, a partial P‐gp substrate, induces greater tumor‐cell death

Long‐Lifespan Polyorganosiloxane‐Based Silicone Evaporator for High‐Efficiency Seawater Desalination

open access: yesAdvanced Science, EarlyView.
Conventional evaporators suffer from salt crystallization and degradation. We design a white polyorganosiloxane evaporator with a reflector, achieving 4.344 kg m−2 h−1 at 1 sun in 3.5 wt.% NaCl. It shows over 53‑day cycling stability and 197‑day seawater resistance.

Comparison of laser ablation, electrothermal vaporization and solution nebulization for the determination of radionuclides in liquid samples by inductively coupled plasma mass spectrometry

open access: yesJournal of Analytical Atomic Spectrometry, 2006
The performance of solution nebulization (SN), electrothermal vaporization (ETV) and laser ablation (LA) of dried micro-droplets as sample introduction systems for ICP-MS are compared for the determination of several radionuclides in digested biological tissue, nearshore sea-water and river water.

Quenching Photo‐Induced Free Radicals Endows Superomniphobic Atmospheric Water Harvesting Hydrogels With UV Resistance for Durable Bifacial Photovoltaic Cooling

open access: yesAdvanced Science, EarlyView.
A hygroscopic hydrogel layer functionalized with fullerene C60 tackles heat and dust challenges in bifacial photovoltaics (PV) panels. It resists soiling and photo‐aging, maintains high transparency, absorbs water vapor from the air during the night, and delivers strong evaporative cooling power during daytime, significantly lowering PV panel ...

Batch‐to‐Batch Optimization of pH Shifts in CHO Bioreactor Operations

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Culture pH is an important operating parameter in CHO cell cultures producing mAb since it directly affects growth and specific productivity. Mathematical models can be used to optimize the magnitude and timing of pH shifts provided that they are robust to model errors.

Methanol With Increased Water Content in Internal Combustion Engines

open access: yesChemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Caps Off to Abstinence: Unraveling Synthetic Cannabinoid Contamination in Hair Analysis With Headgear Evidence?

open access: yesDrug Testing and Analysis, EarlyView.
Scalp hair from a subject claiming 2‐year abstinence tested positive for MDMB‐4en‐PINACA and other synthetic cannabinoids. Analysis of the worn baseball cap revealed an identical drug profile, demonstrating external contamination – rather than active use – as the likely source and highlighting a critical pitfall in hair‐based abstinence testing ...

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
