Urban Waste Management and Waste Management in Nigeria

open access: yes, 2020
The article analyzes the functioning of the waste management system in the cities of Nigeria, which faces real problems in providing proper waste management services. The key factors that limit these pro cesses are identified. Proposals are proposed to improve the management of municipal waste, which will not only solve environmental problems, but also

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

ROBOTS IN WASTE MANAGEMENT

open access: yesDetritus
There are different strategies for urban waste management. At present, solutions are being sought for example to the noise that the collections cause to the inhabitants in the cities, as well as the environmental impact. The introduction of technology and particularly robots in the last time, open an opportunity to develop different applications for ...

Biphasic Co‐Delivery of Curcumin and 5‐FU using 3D‐Printed Dissolving Microneedles for Skin Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Using pixel‐aware digital light processing, the authors created high‐resolution, dissolvable microneedles from a PEGDA/VP matrix. These microneedles encapsulate curcumin and 5‐fluorouracil and dissolve in the skin, co‐delivering drugs directly to tumours.
