Extent of land degradation and status of wastelands in Rajasthan (NW India) with a focus on the Bhilwara District

open access: yesJournal of Agriculture and Environment for International Development, 2016
Geographically, the Rajasthan is the largest state of India. The mapping of degraded and wasteland, its distribution and district wise statistics is very important for land resource management.

Non‐Destructive Laser Nanopatterning of Superconducting Heterostructures in Topological Sn Thin Films

open access: yesAdvanced Materials, EarlyView.
We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

open access: yesAdvanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

open access: yesAdvanced Materials, EarlyView.
Perovskite solar modules face environmental risks from lead and iodine leakage. A dual‐function adsorbent—porphyrin‐modified whitlockite nanocomposites—effectively captures iodine and Pb2+, even under severe damage. Combined with a semi‐closed recycling process, it recovers 96.9% high‐purity PbI2 and reduces residual Pb2+ to <10 ppb, offering an ...

Evolution of the spherical cavity radius generated around a subsurface emitter [PDF]

open access: yes, 2010
The emitter discharge in subsurface drip irrigation can be affected by soil properties. A positive pressure develops at the emitter outlet where a spherical cavity is assumed to form.

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Long-term apple orchard cultivation drives selective accumulation and moderate ecological risk of heavy metals in loess Plateau, China

open access: yesScientific Reports
The long-term intensive cultivation in apple orchards has led to certain heavy metals accumulation yet the relative contributions of fertilizer inputs versus atmospheric deposition remain poorly resolved.

Response of short rotation forestry to dairy farm-pond effluent irrigation : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Agricultural Engineering at Massey University [PDF]

open access: yes, 1999
A growing concern to protect the environment has prompted Regional Councils in New Zealand to monitor compliance under the Resource Management Act (1991) covering the discharge of wastewater into waterways.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
