Low-temperature bonding technologies for MEMS and 3D-IC

, 2022
S.34Recent developments within MEMS and IC call for a reduction in bonding temperature down to 350 °C and below. For MEMS, sensitive mechanical structures, thinned wafers, and heterogeneous integration of temperature-sensitive materials or materials with

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

The low-temperature heat capacity of fullerite C60 [PDF]

, 2015
The heat capacity at constant pressure of fullerite C60 has been investigated using an adiabatic calorimeter in a temperature range from 1.2 to 120 K. Our results and literature data have been analyzed in a temperature interval from 0.2 to 300 K.

Low-temperature tribological properties of Si3N4 ceramic composites incorporating nano/microscale graphene and Si3N4 whisker

Journal of Materials Research and Technology
Si3N4 ceramic bearings have demonstrated significant potential in augmenting the performance of liquid rockets. However, the operational conditions, including reciprocating use, ultra-high-speeds, and high-load impacts, impose more stringent requirements

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Radial thermal expansion of pure and Xe-saturated bundles of single-walled carbon nanotubes at low temperatures

, 2009
The radial thermal expansion coefficient alphar of pure and Xe-saturated bundles of single-walled carbon nanotubes (CNTs) is measured in the interval 2.2–120 K. The coefficient is positive above T=5.5 K and negative at lower temperatures.

A bandgap reference source with higher-order curvature compensation

Dianzi Jishu Yingyong
Based on the 0.18 μm BCD process, a higher-order curvature compensation bandgap reference with low temperature coefficient is proposed. On the basis of the basic Kuijk bandgap reference structure, the VBE linearization method is used to perform high ...
